The most common Ultraloq U-bolt Pro problems

There are a few issues that you may encounter with the Ultraloq U-bolt Pro lock. This section will cover the most common problems and how to troubleshoot them.

The lock is not unlocking or locking using the App

The lock is not unlocking or locking using the App

A problem with your internet connection can cause this, but the unlock code is more likely to be entered incorrectly.

  • Check that your phone has a signal and enough battery power. If using another device, ensure it’s unlocked before using the App.
  • Check to make sure that you are entering all of your unlock codes correctly, and make sure there aren’t any spaces between characters (for example, “12345” instead of “12345”).
  • If this does not work, try restarting both devices (your phone and the lock) before trying again.
  • Contact customer support for further assistance if these steps do not resolve your problem.

Ultraloq U-Bolt Pro fingerprint stopped working.

Ultraloq U-Bolt Pro fingerprint stopped working

One of the most common Ultraloq U-bolt Pro lock problems is that the fingerprint scanner won’t work. Many factors can cause a fingerprint door lock not to work, and it’s essential to try and isolate which one before making any changes. If you’re having trouble with your fingerprint reader, here are some things to consider:

  • Is there dust or dirt on the scanner? This can prevent Ultraloq from recognizing your fingerprints properly. Try cleaning off the scanner with a soft cloth or spray, then try again.
  • Are there any cuts or scrapes on your skin? Cuts, burns, and other injuries may prevent Ultraloq from recognizing your prints properly if they’re too deep or otherwise abnormal. Ensure you have no apparent wounds on your finger before attempting setup again!
  • Ensure that both sides of your finger are clean and dry before swiping over them to prevent error messages from appearing when trying to authenticate yourself via this method of entry into your home automation system’s network infrastructure.
  • Did someone else try using their fingers before yours? Suppose another person tried the lock first (like at an office party). In that case, their fingerprints might still be stored inside even after resetting back to factory defaults – this would cause them not to be recognized as valid users again when trying out yours afterward!

The Ultraloq U-Bolt Pro lock is jammed.

Ultraloq U-Bolt Pro lock is jammed

If your Ultraloq U-Bolt Pro lock is jammed or the U-tec App shows the “Deadbolt is jammed” error, there are a few things you can try before contacting our support team:

  • Check the depth of the frame’s hole. If it is too deep for your door, use a hammer and chisel to make it deeper. Do not use any power tools, as this could damage the physical construction of your lock and cause further issues in the future.
  • Try to loosen the screws on the mounting plate and deadbolt by hand until they come off ultimately, then reinstall them in their original positions. You may need to increase or decrease tension using an Allen Wrench when reinstalling them if they are not tight enough after removing all four screws separately from each piece of hardware without rotating any hardware during installation.
  • Also, check for any debris lodged in your lock’s bolt hole.
  • Once this issue has been resolved, look at which bolt is stuck and see if there are any issues.
  • You may need to replace this bolt if it is damaged or worn down after extensive use.

Ultraloq U-bolt Pro lock connection failed.

If you are having issues connecting your device to the App, ensure that you have downloaded and installed the latest version of the U-tec app.

  • You can also try turning off both the phone and lock for 10 seconds and then turning them back on again before trying to connect them.
  • If it still does not work, try restarting your device by switching it off and back on.
  • Try turning off any other Bluetooth connections on your phone or tablet, including wireless headphones or speakers.
  • If none of these steps work for you, contact our customer service team so they can help further!

The Ultraloq U-Bolt Pro keypad stopped working.

The Ultraloq U-Bolt Pro keypad stopped working

If your keypad has stopped working, try these steps before you contact one of our technical support representatives.

  • The batteries. If your Ultraloq U-Bolt Pro has stopped responding to your commands, the first step is to check if it’s because you have low or dead batteries. If so, replace it with new AA alkaline batteries and try again.
  • Out of range. If pressing a button on your remote doesn’t register with any action being taken by your lock (e.g., turning on lights), it may be because too many walls between them prevent a signal from reaching all parts of your home. Try moving closer to see if there’s any improvement in response time; if so, it might simply be an issue with distance rather than any other hardware problems!
  • Make sure the keypad is not broken by pressing it and making sure it clicks into place. If the keypad still isn’t working, move on to step two.

Ultraloq U-Bolt Pro is not open when you press the button

This can happen if the Bluetooth isn’t connecting correctly.

  • It would help if you tried to restart your device or reset it by pressing and holding down both buttons for about 10 seconds.
  • If this does not work, check your phone has enough battery power by turning on its battery-saver mode (if available).
  • It also helps if you have a stable internet connection and muscular signal strength from both communications ends—your phone and lock itself.

Ultraloq U-Bolt Pro is not working correctly.

Ultraloq U-Bolt Pro is not working correctly

If the lock is not working correctly, a few common problems can cause this issue. Ensure the battery is installed correctly and fully charged before using the lock again. If you’re still having trouble with your Ultraloq U-Bolt Pro, try checking these things:

  • Make sure your doorknob is fastened tightly and not crooked in any way. The device must be securely fastened to the door to work correctly.
  • Ensure all your battery covers are snapped in tightly so they don’t come off while using or transporting the product.
  • Check for any loose screws on the inside or outside of the lock; if any visible screws or bolts are missing from either side of your unit, consult an expert who can make repairs before attempting continued operation.
  • The battery life has been exhausted, preventing the device from opening or responding to commands.
  • The Bluetooth connection between your phone and the door lock is not working correctly, so you may be unable to control it with your smartphone app.

The lock will not auto-lock after the door is closed

The lock will not Auto Lock after the door is closed

If the lock will not auto-lock after closing the door, please check whether you have the following troubleshooting steps.

  • The first thing to check is your door sensor. This sensor should be in place and adjusted correctly. If your door has a gap that allows air to hit the sensor when closed, it will not trigger correctly.
  • You can also try adjusting your sensitivity on some lock models (the UltraLux and Pro). This involves disconnecting power from the lock and turning its sensitivity using a screwdriver or Allen wrench.
  • Check the battery. Ensure you have a working 4 AA alkaline battery inserted into the lock. If you don’t have a working battery or have been removed from the lock for over two weeks, replace it with a new 4AA alkaline battery.
  • Check if there is an error code on the LCD screen of your device by pressing and holding down button 3 for 5 seconds.
  • Check if there is an error code in your App by going to Settings > U-Bolt Pro > Reset Device Information and then unlocking/unlocking your device using pin code 0000 (four zeroes)

Ultraloq UL3 troubleshooting

If you are having trouble unlocking or locking the lock using the App and keypad, you can troubleshoot the Ultraloq UL3 keypad lock by following these steps:

  • Make sure you’re using the correct code on your UL3.
  • Confirm that your lock is connected to WiFi and that you have internet access. We strongly recommend scanning for nearby networks if no internet connection is available.
  • Try turning off and restarting your phone.
  • Check for any moisture or dust obstructing the sensor bar. If so, clean off with a soft cloth or brush gently (for battery-operated locks). Check if it unlocks now (for battery-operated locks)
  • Verify that there is power to the lock. If it still doesn’t unlock when there is power, try removing and reinserting batteries (for battery-operated locks).
  • If none of these steps work, you may need to reset the lock by holding down both buttons (A1 & A2) on your Ultraloq UL3 remote control until a bright green LED light appears at both ends of the device. This will take between 3-5 seconds.
  • Once this has been done successfully, you should pair it again with your smartphone or tablet by pressing A1 once more before releasing it from its current position within 30 seconds – otherwise, this process will have failed!
