Tools & Requirements

Step-by-Step Solution

1

Clean the Touchscreen Surface

The Yale Assure Lock SL has a capacitive touchscreen on the front exterior panel. Dirt, moisture, dried rain spots, and fingerprint oils can interfere with touch detection. Wipe the touchscreen surface with a dry, lint-free cloth. Do not use glass cleaner or liquid cleaners on the touchscreen as moisture can seep into the electronics behind the panel.

2

Replace the Batteries

Low battery voltage causes the touchscreen to become sluggish or completely unresponsive. The Yale Assure SL uses 4xAA batteries inside the interior assembly. Remove the interior cover by sliding it upward off the mounting plate. Replace all 4 batteries with fresh alkaline AAs — do not mix old and new batteries. After installing fresh batteries, test the touchscreen immediately.

3

Check for Extreme Temperature

Capacitive touchscreens lose sensitivity in extreme cold (below 0°F/-18°C) and extreme heat (above 120°F/49°C). If the lock is on an exterior door exposed to direct sunlight or extreme winter cold, the touchscreen may become temporarily unresponsive. Shield the lock from direct sun exposure. In cold weather, cup your hand over the keypad for a few seconds to warm it before entering your code.

4

Test with Multiple Fingers

If the touchscreen responds to some touches but not others, try pressing with different fingers and firmer pressure. Dry skin reduces capacitive touch sensitivity. Moistening your fingertip slightly can improve detection. If only certain areas of the keypad are unresponsive, the digitizer behind the screen may be partially damaged.

5

Factory Reset the Lock

If the touchscreen remains completely unresponsive after battery replacement and cleaning, factory reset the lock. With the door open, remove the battery cover. Press and hold the reset button (small button inside the battery compartment) for 10 seconds. The lock will beep and reset to factory defaults. Reprogram your master code and user codes after the reset.
