Lockly Fingerprint Not Working: Try These Troubleshooting Tips

1. Straighten the Bent Pins in Your Lockly Smart Lock’s Cable Connector

While you were setting up your Lockly smart lock, you may have mistakenly bent some pins in your cable connector. Unfortunately, your Lockly fingerprint sensor won’t work if any of the pins in its cable connector are bent.

To fix this issue, you’ll need to straighten the bent pins in your cable connector.

Here’s how to straighten the bent pins in your smart lock’s cable connector:

Remove the touchscreen from your Lockly smart lock by sliding it up. This will reveal two of the screws that hold the lock to the door.
Unbolt these screws to reveal your Lockly cable and cable connector.
Detach the cable connector from its socket.
After detaching your cable connector, turn it over.
You’ll now see the pins in the cable connector.
Place a screwdriver at the back of each bent pin and carefully wedge them back into place.
Once you’ve straightened all the bent pins, insert the cable connector back into its socket and bolt the removed screws.

Your Locky fingerprint sensor should start working now.

If the problem persists after trying this fix, continue to the next step.

2. Insert Your Lockly Cable Connector Properly

If your Lockly fingerprint sensor still fails to detect your fingerprint after you’ve straightened the pins in the cable connector, check whether the cable connector is inserted properly.

Here are the steps to follow to re-insert your Lockly cable connector into its socket:

Open and detach the touchscreen from your Lockly smart lock.
Remove the screws from the lock. This will expose the cable and cable connector.
Remove the cable connector from its socket.
Then re-plug the cable connector into the socket firmly.

Your Lockly fingerprint sensor should start working now. If not, keep reading.

3. Change the Batteries in Your Lockly Smart Lock

Your Lockly smart lock is battery-powered. And when the batteries are running low, the performance reduces.

If your fingerprint sensor was working properly but suddenly stopped, chances are the batteries in your lock are running low.

Most Lockly smart lock models will display a low battery icon on the screen when the batteries are low. Check to see if you can find the low battery icon on the screen of your lock. If yes, it means the batteries are low and require replacement.

If you don’t find the low battery icon on the screen, you should still replace the batteries to see if it fixes the problem. Sometimes, your lock may not display the low battery warning—probably because the batteries are bad or so.

Follow these steps to change your Lockly smart lock batteries:

Detach the touchscreen from the Lockly smart lock by sliding it open. This will reveal the battery compartment.
Before taking out the old batteries, you still have to unbolt the screws at the top and side of the battery compartment.
After removing these screws, you can remove the batteries.
Now, insert the new AA batteries, observing polarity markings (+/-)
Bolt the screws you’ve removed earlier. Then return the touchscreen back to its place.

Ensure you get the correct batteries and do not mix new batteries with old ones.

4. Restart the Lock

If your Lockly fingerprint sensor still fails to recognize your fingerprint after fixing the cable connector and replacing the batteries, try restarting the lock.

Take the following steps to restart your Lockly smart lock:

Look for a hole between the two terminals at the bottom part of the front of the lock.
Use a paper clip or pin to poke this hole.
Now, with the paper clip or pin, press and hold the button until your Lockly smart lock restarts. This should take about 5 seconds.

After restarting the lock, the fingerprint sensor should start working.

Wrapping Up

So that’s how to troubleshoot fingerprint sensor issues in your Lockly smart lock.

To recap, if your Lockly smart lock fingerprint sensor isn’t working, replace the batteries in your lock, check and straighten bent pins, then insert the cable connector properly to resolve the problem.

If the problem persists, restart the lock to see if it works. If not, try contacting Lockly Customer Support for help.
