Saihisday Left Front Door Lock Actuator for Honda Civic 2006-2011 - Driver Side, Direct OEM Fit

Saihisday's left front power door lock latch actuator (part 72150-SNA-A14) replaces the driver-side locking motor on Honda Civic sedans from 2006–2011 to restore reliable central-locking operation.

If your Civic’s driver-side door no longer responds to the key fob, interior lock switch, or makes grinding noises when locking, the actuator is a common cause. This replacement is built to match the fit and function of Honda part numbers 72150-SNA-A14 and 72150-SNA-A12 and supports multiple Civic trims including EX, LX, GX, Hybrid, and EX-L across 2006–2011 model years.

How will replacing this actuator improve my car’s locking system?

Swapping a worn actuator restores consistent electronic locking and prevents the inconsistent or failed lock responses that can leave doors unsecured. The motorized latch provides the proper travel and catch that interfaces with the OEM linkage and wiring harness.

• Replaces failing motor that won’t move the lock rod fully.
• Eliminates grinding sounds and intermittent locking.
• Works with factory wiring and connector for plug-and-play replacement.
