Normally when you start the car and put it in drive the door locks automatically lock. They aren't doing it anymore... did I accidentally turn this feature off or is something wrong.
Check the owner's manual, as I believe you may have inadvertently turned it off at the remote entry keypad on the driver's door.
Do your backup lights work? If so, it's likely the RKE module is getting the signal to lock the doors, so it is either inactivated or there is an issue with the RKE system.
1. Enter the permanent 5 digit entry code(not the user code you may have set).
2. Within 5 seconds, press and hold 7/8.
3. Within 5 more seconds, press and release 3/4.
4. Release 7/8.
To deactivate, repeat the instructions to activate the Auto Door Lock Feature.
