Product Overview
When the driver lock button is cracked, peeling, loose, or intermittent but the door actuator still responds from other controls, the local switch is the part to compare. It will not fix a failed actuator, fuse, harness, or central-lock module.
The switch restores the local lock/unlock command. It does not repair a failed actuator, door harness, fuse, or central-locking module.

Frequently Asked Questions
Q: How do I separate a bad switch from an actuator fault? A: If the door responds to the key fob or another control, the local switch becomes more suspect.
Q: Does it fit the passenger side? A: No. It is for the front-left driver position.
Q: Will it program a key? A: No. It only sends a central-lock command.
Q: Can cosmetic peeling justify replacement? A: Yes. Some buyers replace a working switch to restore interior appearance.
