Fingerprint Tips for Ultraloq Lever

Please read this article to solve the problem if your fingerprint fails to unlock your Ultraloq Smart Lock.


Common causes of Low-Approval Fingerprint Verification

The following are some circumstances that can increase the chance of fingerprints being rejected:

1. Frequently washing/disinfecting hands.

2. Activities that require using the fingertips include weight-lifting, rock climbing, gardening, or playing guitar.

3. Frequent or regular handling of paper or typing.

4. Exposures of chemicals, such as bleach, chlorine, acetone, and antibacterial products.

5. Age: Skin becomes smoother, and ridges become harder to capture with age.


Tips for Successful Finger Verification

> The finger is clean and without any callus. It's not peeling or injured.

> Don't tap too quickly or move your finger around while scanning the fingerprint.

> Cover the Fingerprint Sensor completely with some pressure, not too light or hard.

> We recommend that each user register multiple fingerprints.

> If the fingerprint is wet, please dry your finger.

> Ensure your finger is at the same angle as during enrollment. Even moderate changes in finger angle during touching can cause the match failed error.


Troubleshooting for Failed Fingerprinting

Please follow the steps below if you have referred to the tips above and are still getting failure notifications while scanning the fingerprint.

Step 1. Power cycle your lock by removing and reinserting one of the batteries. If the battery is low, please replace them with brand new ones.

Step 2. Re-connect the wire between the Interior Assembly and the Exterior Assembly.

Step 3. Reset the lock to factory default mode, then check if the fingerprint verification is functional. In factory default mode, any fingerprints can unlock the lock.

Step 4. You can check by using other users' fingers to verify the fingerprint function.

When you touch the fingerprint reader and don't get any response, please submit the problem to Ultraloq Support Team will help you further.
