Q: My car won't unlock

asked by on

My car unlock at all! I replaced the battery in my remote and tired to use the key in the door! And it still won't open

My car has 135000 miles.
My car has an automatic transmission.

When this situation occurs, it’s commonly due to a failure within the power lock module, which is what receives the signal from your FOB key and sends a signal to each door to unlock. However, it could be a simple fuse or electrical relay that damaged. It’s probably best to have a mobile mechanic complete a power door lock inspection to determine the precise cause of your problem.
