Please correct me if I'm wrong, but the ETACS system in our cars is what automatically unlocks the doors (right after you've locked them) if you have a door open and your key in the ignition. This portion of the system has always worked for me until recently. For some reason, I can shut my car off and remove my key from the ignition, open the driver's door, and lock the doors from the driver side. This tells me that the switch telling the ETACS system that the key is NOT in the ignition is there and working. However, if I shut my car off, open the driver's door and try to lock the PASSENGER side, just recently it has started not allowing this.
Any thoughts as to why this is happening?
