🔧 Altima - Front Door Lock Actuator Replacement

On your Altima, the “door lock actuator” is typically part of the door latch/lock assembly inside the door. Replacement requires removing the interior door panel, peeling back the moisture barrier, then swapping the latch/actuator and reconnecting the lock rods and electrical connector.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• ⚠️ Turn ignition OFF and remove the key/fob from the car before unplugging door wiring.
• ⚠️ If your Altima has a door-mounted side airbag, do not probe yellow connectors; disconnecting the 12V battery is recommended.
• ⚠️ Wear gloves—inner door metal edges are sharp.
• ⚠️ Support the window glass if you end up loosening any window hardware.
