I replaced the headlight bulbs in my car on Saturday. Now a new problem started this morning (Tuesday). The doors immediately re-lock when trying to unlock them with the keyfob, door handle button, or inside door switches.

All 3 methods make the door unlock, but then it immediately locks itself again. The only way to get in or out of the car is to use the manual key or the manual door lock lever on the inside of the car (right by the handle to open the door).

I have tried taking the battery out of the keyfob, but the car behaves the same way. This is really annoying. Where can I start troubleshooting?

Thanks.

I know it's a shot in the dark, try disconnecting the car battery for a 10 minutes, then reconnect...

The problem worked itself out. I left the car at a job site in the hot sun the other day, and the locks have been back to normal every since.

For what it's worth; there is a setting for the time-frame after which your doors will "auto-relock"... It's under system settings I think.. In fact, that was going to be one of my newbie questions.. I've set mine to auto-relock in 1 minute.. But I haven't seen it work yet
