Frequently Asked Questions
Can I still lock the door manually?
Yes. Most vehicles still have a manual lock button or knob on the door panel that can be used to lock and unlock the door even when the power lock actuator has failed.
Why does the actuator click but not lock?
A clicking sound without movement usually means the electric motor inside the actuator is running but the internal gears or linkage have stripped or broken, requiring actuator replacement.
Is the actuator hard to replace?
Moderate difficulty. It requires removing the door panel and possibly the window regulator to access the actuator inside the door. It typically takes 1-2 hours for a skilled DIYer.
