Step 3
Test the door lock click
Close the door and press firmly until you hear one distinct click from the lock mechanism, not two. A double-click indicates the lock spring is worn.

Step 4
Inspect the striker
Look at the metal striker hook on the door edge. It should be straight and not bent. A bent striker cannot engage the lock.

- • Door closes firmly but dE persists (faulty door lock switch)
- • Lock makes no clicking sound when door is closed
- • Door hinges are visibly damaged
