Tips for Improving Ultraloq U-Bolt Series Fingerprint Verification

Please read this article to solve the problem if your fingerprint fails to unlock your Ultraloq U-Bolt Series.

What's the Fingerprint Sensor of Ultraloq Smart Lock?

A Fingerprint Sensor is an electronic security system that uses fingerprints for biometric authentication to grant the users access to your Ultraloq Smart Lock. Fingerprint Sensors of Ultraloq Smart Locks differ from Smartphones, Computers, and other devices due to the unique hardware and algorithm. Please follow the next instructions to register and don't refer to any other methods. 


Common Causes of Low-Approval Fingerprint Verification

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

> Frequently washing/disinfecting hands.

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

> Frequent or regular handling of paper or typing.

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

> 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.

> You must touch the surrounding metal ring when you place the finger.

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

> Please scan multiple fingerprint angles while registering a fingerprint. 

> U-Bolt Pro fingerprint sensor has a self-study function in which the verification rate will be improved after various successful accesses.


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 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.


Note: Most people following these tips will have significantly improved their fingerprint verification rate. A tiny percentage (about .1%) of people will not produce acceptable prints.
