If deadbolt does not extend or retract easily when testing thumbturn and keypad operation, revisit inside and outside lock installation steps. It is important that the bolt be in the retracted position during lock installations and that installation procedure is followed carefully.
Helpful Tip:Ensuring smooth deadbolt operation can enhance your battery life.
If you feel resistance, ensure deadbolt strike plate aligns with deadbolt. If deadbolt strike plate is out of alignment, please attempt to adjust knob/lever/handleset strike using steps below. The knob/lever/handleset latch engagement into the strike is the main component used for door alignment.
If deadbolt does not fully extend, consider increasing depth of deadbolt strike pocket in frame.
To adjust Knob/Lever/Handleset strike plate:
- Remove plate from door frame with a manual screwdriver (Using an electric driver may strip screw heads or enlarge screw holes).
- Locate strike plate tab. Bend the tab towards surface of strike. Note: a small change may be all that is required
- Reinstall strike plate using a manual screwdriver and test again
- If door cannot be adjusted sufficiently with strike tab, both knob/lever/handleset latch and deadbolt latch could require adjustment – we suggest you contact a local locksmith for assistance.
