Vehicle Lock Repair: preparing for the visit

The button on your key fob does nothing now: no beep, no flash of the lights, no click from the doors. The metal blade folded inside the fob still turns the door by hand, so you are getting in and out, just without the remote.

Worth answering before the call

Which lock is affected: a door, the trunk or hatch, or a storage compartment? Has the key fob's battery been replaced recently, or not that you recall? Is there a spare key or fob you could compare against the affected one?

Does a repaired vehicle lock still use my original key?

Wherever possible, yes. The point of repairing rather than replacing a lock outright is to keep it working with the key and fob you already carry, so the whole vehicle continues to answer to one set rather than needing a second key for one door.

The remote does not work on one door, but the key still does. What is going on?

This pattern usually points to the power lock actuator on that specific door rather than the mechanical lock, since the key path and the remote path use different components once they reach the door. The actuator, its wiring, or the connector near the hinge are the likely places to look.
