Do you need to replace the door lock actuator of your Mitsubishi Mirage? This step-by-step guide will show you how! Are you more of a visual learner? Follow along with our video guide below:
At a Glance
- Fits: Mitsubishi Mirage G4, same steps for all four doors
- Symptom: one door will not lock or unlock with the remote or switch
- Tools: trim tool, screwdriver and Torx set
- Access: remove the door panel, then the actuator screws at the latch
- Check first: fuse and key fob battery if no doors respond
Is It the Door Lock Actuator?
- One door will not lock or unlock with the remote or switch, but the others do: the actuator in that door is the usual cause.
- Buzzing or grinding from inside the door when locking: worn gears inside the actuator.
- Lock works sometimes, especially in warm weather: a weak actuator motor.
- No doors lock at all: check the fuse, the key fob battery and the lock switch before replacing actuators.
- Door will not open from inside or outside: may be a disconnected handle rod or cable, not the actuator.
Tip: on many cars the actuator also contains the door ajar switch, so a failing actuator can cause a door open warning or interior lights that stay on.
What you will need
- Prying tool
- Screwdriver

Frequently Asked Questions
How do I know if my Mirage door lock actuator is bad?
If one door will not lock or unlock while the others do, or you hear buzzing inside that door, the actuator is the likely cause.
Can a bad door actuator drain the battery?
It can if its built in door ajar switch fails and keeps the interior lights or modules awake.
Do I need to remove the window to replace the actuator?
Usually not. Roll the window up, remove the door panel and water shield, then unbolt the latch and actuator assembly.
