      Ask a Question
      • I have purchased a Nulock through Amazon just last week. I think the lock is a brilliant idea,but I cannot seem to get it to work. Here is the problem. I have done all the instructions and I lock the lock and press the button on the lock and the red light comes on and the app confirms the lock is closed. Yet when I check the lock to see if it is closed, once I press the release button,I can pull the the lock open even though the app is telling me that it is closed. Any idea how to solve this problem. Have to say, a brilliant idea. I hope you can help me please.

        Hi Michael,
        When you press lock button, did you hear "BiBiBi" beeps? You might need to wait a couple of minutes to make sure the lock truly connected with your phone. When the lock is unlocked and the cable bolt is pulled out, the app should show "connect failed" in red. After you press the lock button then wait a few seconds, then the app should show "connect success" in green. If you still have problem, please send us an email with your order ID with your phone number. 

      • When the alarm on the lock goes off, will you be notified on your phone that the alarm is going off?

        The Nulock is a bluetooth device. It will only notify you when your phone is connected or disconnected the Nulock on bluetooth. Since the alarm only works when your phone is disconnected with the device on bluetooth, you will not get notified about the alarm. It will need sim card to transfer data to send you notification from Nulock. But that will involve much more power consuming and also data service. The alarm is used to deter the theif away though.

      • I switched services and got a new phone. How do I reconnect to my nulock?

        Dear customer,
        No matter you are changing your phone service or you need someone else's phone to unlock the nulock, you can always download the free app "Nulock" to your phone then type in your password then unlock it. Please keep in mind: you can only use one phone to connect to the device since it is bluetooth connection. And also please remember your password if you change it.

      • Ill be in my motorhome in the mountains away from phone service. How do i operate the lock under those conditions?

        Hi Dennis,
        Nulock is a bluetooth device. You can set it up or control it without data service just like operating a bluetooth speaker. That means you can lock, unlock, set up alarm etc no matter you are in the mountailns or on the sea, as long as your phone is in the Bluetooth range (around 30 feet). The alarm will be ready to work when it is not connected with your phone (we don't want it to disturb the owner) and you have turned on the vibration on. Alarm goes off when vibration detected, battery cover screws removed or cable cut.

      • I just bought one of these bike locks. When I insert the battery it only beeps twice, and does not lock. Can someone help please?

        Thanks for your purchase. Yes it only beeps twice when you insert the battery as you can see from the video: Our manual is There are a few things I need to confirm before you operate the lock: 1. You have to put battery cover on with screws tightened in. 2. Put the lock button on the front panel to lock it. More detail information can be found in our product page and video testimonies.
        If you still have question, please contact us and let us know.

      • So, I have a discount code from I read that you have plenty of the 41" locks but your site has not been updated to reflect anything but "sold out". Its hard to order when the order won't "take"! So, how do I order before the 4/30 deadline?

        Hi Thanks for your interest of our 47" Nulock. The 47" long cable might allow you to lock two bikes or two wheels of most bikes. We have updated our website and put this one into back ordered. So now you can place an order by using the coupon code you have. We will lock the price and save the inventory for you when we get the shipment. We should be able to ship it out before 5/10/2017.

      • I want to rent my bike in Spinlister. Is it safe?

        That is a good idea. We encourage bike sharing. With Nulock, you just need to send the password to the bike renter. Actually you do not need to meet the renter face to face. Just get one of NuCam 720p light bulb camera. Then you can check from the camera to see whether they come to pick up or have returned it. It is like double security. Just make sure they did not change the password. Please share your experience with us if you have done so. 

      • If someone takes the battery off, will they unlock it?

        Well the electrical circuit of the device is specially designed. If that happens, it will keep alarms which tells the thief to stop. If they determine to do so, they still can not press the unlock button to release the bolt! If you need a battery cover, we can send you a replacement one. 

      • The device sometimes beeps when I move it. When it keeps alarming if I park it outside of a store and someone touches it accidently?

        Great question since you care! But this device is "smart". The device beeps only when your phone is not nearby or you turn off the bluetooth, andyou have set the vibration on in the app. Just remember to keep the bluetooth on or turn off the vibration. If someone moves your bike and Nulock triggers it, it will give out a one-beep warning. If the movement continues in 5 seconds, then it will get off for 30 seconds. It will not keep alarming. It is just a feature to deter thieves away and notify you by sound. 

      • Can I use my phone to control multiple devices?

        Yes, you can control them together under one app. You can rename each device differently. And you can use multiple phones to control one device. But one time it only allows one phone to conect to one device. 

      • If I forget to bring my phone or it is out of battery, how can I unlock the device?

        Wow, it is just like you lost your key for a regular lock. No I am kidding. You are OK. You are not screwed. How about borrowing a phone from your friend and type in your password. You changed the password and do not remember it, and you do not have your phone! This is a very rare situation. We can not recover the password for you since it will bring hole in our app to those hackers. That is why we put a card inside the pacakge and encourage you to write it down. 

      • Why my phone can not connect to the device?

        Since it is a bluetooth smart lock, please double check the following points: The bluetooth of your phone is on The battery cover is on with screws tightened in There is no other phone connected to the device. 

      • Is a PDF copy of the owner's manual available for download?

        Yes of course. Please send an email to From there, we can reply with our PDF Owner's Manual. 

        Thank you, 
        NuVending Team 

      • I got a new iPhone 13 and the nulock app that transferred with my old phone data reports "unable to install "nulock." The app is no longer available in the App Store." I cannot operate my lock without it! Since the App Store no longer carries this app, where can I download it?

        You can download and use SLBLOCK app.

      • when I try and scan for the device it does not find it? does it say Nulock or solebe? or is it called a different name?

        The "QR code is for searching the "Solebe" app, not for searching our Nulock device. Please choose "search the device" when adding device in the Solebe app. Type the default password shown in the manual to connect to the device.

      • The Nulock Smart Lock with Alarm won't pair? It won't scan the bar code either?

        The barcode is only used to get the app not for pairing with the lock. If you just get our Nulock, then you need to use Solebe app and search the device (Default password is 123456. Not scan the device. Make sure the batteries installed with screws tightened and press the lock button tonight the front panel. Bluetooth needs to be turned on).

      • We purchased a bike lock Nulock and playing with it to see how it works, and was having trouble disengaging it. Went to take out batteries and now it will not stop buzzing and can not turn it off. I had this app on 2 phones and in the process I tried removing app and reinstall from one phone. From this phone I forgot Original password. Made a real mess.... are you able to help? Ron Bike lock

        Hi Ron, You can call me at 6262050828 to get an emergency password. Roy

      • I can’t find the app online. Where can I get it?

        If you purchased our Nulock more than 2 years ago, then you can continue to use our old model with an iPhone by downloading "SLBLOCK" app. Otherwise if you purchased it recently, you can download the "Solebe" app.

      • I lost the two tamper screws when I replaced the batteries last time. Can I buy them somewhere?

        Hi Roald, I am sorry to hear that. If you can buy anything in our website, then we can send you two screws together for free. Thus the shipping fee will get covered. Thanks! Roy

      • Your app Nulock dissappeared from poland how do I unlock the device ?

        Please search "Solebe" APP in Google or APP store.

      • If I turn off blue tooth on my phone and turn back on with the lock locked then turn on blue tooth back on the lock says it is connected but will not unlock. If I uninstall the app and reinstall app find the device put in password I can then unlock. if I get out of range of the lock and come back into range the lock repairs fine and works. Is this Normal?

        Hi Mark,, Are you using Auto Unlock feature? Auto Unlock will make the lock unlocked automatically when your phone is connected to to the lock on Bluetooth. If in manual unlock mode, then you might need to wait a few seconds to make sure the lock is connected completely after it says connected in the app. Please let me know whether it fixes the issue.

      • My Nulock battery has died with the lock still locked and securing my bike. I cannot connect to the NuLock because the battery has died. I cannot unlock the lock to free bike. What should I do?

        Hi The app should have given you warning when the battery is essential than 20%. If you have the included screws with you, then you can change the battery.  When you put in new batteries in, the alarm might go off.  You can turn on there app to disarm and unlock the device(make sure they battery cover is screwed tightly).

      • Dear NuLock, I purchased the NuLock cable for my bike. The app and lock have worked great. However, the  mechanical red button release is not unlocking the cable.  Worst thing is that I’m moving out of my apartment.  The app works:-Red light when is locked-Blue light when is unlocked Even the auto-unlock works perfectly.  The lock’s light is blue, the app shows the lock as unlocked and I can still push the red release button (although it is hard to press) but it won’t release the cable. I can jiggle the cable (it moves) but it won’t released.  What can I do? Please help!

        Hi When did you buy our Nulock? Can you please give me your order ID? Our old model uses the old app "Nulock". But our new model uses the new app "Solebe" to make it more compatible with the most updated Android phones. Please also try to use new batteries to see whether it works. If in any chance it turns out to be defective, we can send you a replacement one. Thanks!

      • If the alarm goes off for 30 seconds and the thief walks away. Will it then reset itself and will the alarm go off again when the same thief or when someone different tries to steal the bike?

        Yes the alarm will reset after it stops. It will be triggered again if movement is detected.

      • Also, does a current run through the exposed metal along the top of the locking mechanism? Where someone can overload the lock with their own supply of electricity?

        Yes the cable makes a closed loop circuit. If someone cut the cable when the lock is in locked status, the alarm will be triggered. The owner will have to use the phone to pair with the lock to disalarm. We did not try that part by overloading electricity through the lock. But they will have to do it when the lock is open right? Otherwise the current will just go through the cable and bypass the lock. It will not hurt the lock anything. So it is only an experiment to do that when the lock is open.

      • how muffled does the alarm get if the thief were to place their palm on the opening?

        It is 110dB alarm. The people will still be able to notice the triggered alarm even if they place their palm on the speaker. The purpose of the alrm is to deter the thief away. Normally in this situation the thief will just pass your bike and target for the next one.

      • Do you have a longer model?

        Yes we have 71" long cable version. Please find it out.

      • I just got my Nulock. Tried to connect to the app but can not. I have a Note 10 plus. The app scan just spins without connecting. gps and BT are on. I can scan with BT and it finds and connects to the smart lock but not through the app slblock.

        The app is called Solebe. Please try it again.

      • What is the range for the alarm 20 m-200 m?

        The alarm is at 110dB. Pretty much like the alarm for some cars.  If you are not far, you should be able to hear it.

      • I change the batteries but every time I put the last battery the alarm goes off so I have to take out the batteries and also my phone don’t connect to the lock any more and keeps scanning now my bike is lock for the last four months I try different things and none work I’m thinking of cutting the cable now!!

        Hi Edgar,  If you take the battery out before you unlock the device, it will trigger alarm in our Nulock. This was designed to deter thieves away if they try to mess up the device. So now I recommend you to first add new device then add new batteries and at the same time use your hand or cloth to cover the speakers. Please also remember to tighten the screws. If your device has been added to the device already, please wait a little bit for the device to get connected. Please let me know whether it works.

      • I added my batteries and couldnt get it to connect so i removed batteries and the alarm started going off now I cant pair it to the app because everytime i remove the batteries it goes off How do I fix this

        Hi Joe, when you take out the battery when the lock is still locked, the alarm will go off because that is like a stranger's behavoir. The normal process is to unlock it first in the app then take off the battery. When the alarm goes off,alarm will be killed after you take off the battery but it will resume when you put the battery back. At this situation, you can use hand to cover the speaker then put battery and battery cover back and tighten two screws. Then you can go the app to scan for the device. Now the alarm should be gone. Make sure the LED indicator flashing red after pressing lock button. After unlocked, it should go to blue. Please try again to see whether you can pair with the lock.

      • Recently got a new phone and I downloaded the app again and it’s nit connecting to my nuclock what could be the problem. What do I do. Batteries are new and when I press the button it blinks red and blue but never connects. Help thanks 🙏🏾

        Hi Geo, the indicator blinks red and blue that means it is in low power. Are you sure you put in new batteries? Could you please find other new batteries and try again? It should blink red and changes to blue after connected.

      • what if you lose your password?

        If you lose your password, please send it back to us then we can reset it for you. But as long as you connect it to your phone, then it should be able to connect automatically. You can reset the password then write it down before you might forget it next time.

      • changed phones and in-advertanly locked bike lock. do not remember password. downloaded app again but asking for new password which I dont know

        Hi Matthew, you can ignore the new password reminder. As long as you did not change the default password, then you can unlock it with "123456". Please let us know whether it fixes your issue.

      • How do I change the battery??

        Hi When your phone has paired with Nulock, then you can use the included screwdriver to take screws off and change the battery. Otherwise it might trigger alarm from the device if your phone is not connected with the device. 

      • If Nulock is locked and batteries are removed and then cable cut will the alarm still go off?

        If Nulock is locked and your phone is not nearby or not connected, then the disassembly of the screws from battery cover will trigger the alarm. We expect the 110dB alarm will deter the thief away before he/she continues to take batteries off and decides to get a tool to cut the cable. Of course almost no lock could stop a determined thief. If the batteries are taken off, then no alarm will go off. We will design a new model with integrated rechargeable battery.

      • Can I lock the NuLock from my phone or does it have to armed from the lock itself?

        Hi Larry,
        Sorry to get back to you late. You can only lock the device if you are using AutoUnlock mode. When your phone is out of Bluetooth range, Nulock will get locked automatically. If you use manual unlock mode, then you will have to press the lock button on the front panel to lock the device. The alarm and speaker are built in the lock so it will arm from the lock itself. Thanks!

      • I get the lock locked and beeps 3 times and see a flashing red light however when I move out of Bluetooth range I open up the app and it says "connect failed" does this simplely mean the Bluetooth is disconnected? I'm worried that the lock it's self is "unlocked/failed" how do I see/know if the lock is still locked via the app?

        Yes after you press the lock button on the front panel and you hear 3 beeps then it means the device is locked. It will keep as locked even if your phone moves out of the Bluetooth range, or someone tries to take out the screw and batteries out (the alarm will be activated though) until you bring your phone back and press unlock button in the app. The connect failed notification just gives you a reminder that you are out of the Bluetooth range now. 

      • Im having issues unlocking. It takes several attempts for the app to conecto to the lock. It gives a message of conection failed. I tried turning the wifi off , thrning the bluetooth off and on restarting the phone, resting the cell aginst the lock etc etc. It takes up to 5 minutes everytime to finally get it coneccted. The batteries are fresh they are at 89%.

        Hi Norberto,
        Can I know what phone you are using? Some Android phones might have issue to connect to our Nulock. You can also move the Nulock and your phone to another location where no other Bluetooth interference and try again. Just make sure your bluetooth is turned on and connect it on the app. Please let me know whether it improves.

      • the app is no longer working, what will be the new app?

        Did you buy our Nulock before 2020? You can try to use "SLBLOCK" app in iPhone on our old version of Nulock. If you only have an Android phone, we can give you a discount code to try our new version of Nulock which can be used with "Solebe" app in an Android or iPhone.

      • I just got my Nulock and got the app working on my phone. I want to have it on my wife’s phone as well Can I have the app on 2 phone to use the same lock?

        Yes you can have the free "Nulock" app on different phones. So if your phone is dead or you want to share the lock with someone else, then all of you guys can use it as long as you guys have the password. Just a reminder, like other bluetooth devices, you can only connect to one phone at one time. So if your phone can not connect to the device, then you should check to make sure your wife's phone is not connected to it.

      • My daughter stopped using this lock a couple years ago, and now it is locked and the batteries died. I replaced the batteries and the alarm screeches. I screwed on the cover and hit the plus sign in the Solebe app, but the app doesn't show the lock. My phone's bluetooth is on. I have the password written down and am ready to enter it, but the new app won't recognize the lock.

        Hi Brian, for the old model your daughter bought a couple years ago, the app should be "SLBLOCK". You can go to find it in Apple app store. If you are using an Android phone, then unforatuately SLBLOCK has been discontinued in Google Play store. Thus we can give you a discount code to try our new model to use in Android phone. Please let us know.

      • I just activated my Nulock. Now, I am getting constant Solebe notifications and my phone indicates that Smartlock is disconnected. My phone tells me that my Bluetooth is on. If I cannot get this problem resolved, I will have no other choice than to return the product and purchase a different lock. (8 notifications and counting!)

        Hi Rich, You can turn off the nofication function in the settings of  "Solebe" app. That function will send you notifications when your phone is connected or disconnected with the lock on Bluetooth. Normally Bluetooth range is around 30ft. So when you walk around, ythe app might keep sending you nofications and tell you the lock is connected or disconnected. We just need to turn on Vibration mode and keep notification off.

      Bought one... and then 3 more

      I ordered one of these locks after watching a video and I was not disappointed. It arrived within a few days and packaged well
      After testing the lock to see if it functioned as demonstrated, which it did, I decided to purchase 3 more for gifts.
      I do believe this lock will protect my bike and since there isn't a key to loose... its even better.
      4.8..... great product that I would recommend.


      Great lock but I didn’t know that u get a draw string carry I didn’t get one 😢😢😢

      How do I unlock my bike now?
      Is this lock useless now??

      Jared J C
      Great Product!

      I use this lock to lock up my Rad Rover Bike and when I'm not using it for that I use it for locking up my inverter generator when we are camping. I love that it has a alarm and controlled from my iPhone. If you ever need assistance with the product their is support for help. They stand behind their product.

      Vibration sensitivity

      I notice that I can put groceries into the bikes saddle bags and the alarm does not make a sound with the vibrations I do. Can the sensitivity be adjusted?
