My son connected up his iPhone to my car via bluetooth recently. He did it while I was driving the car on an errand. When I tried to used the remote to lock the car and set the alarm when I parked, nothing happened. The remote will not lock or unlock the doors or open the trunk. I have 2 programmed as admin keys but neither one works. Both work to start the car. Also, the door keypad does work to lock and unlock the doors but will not set the alarm. Strangely enough, the TPMS light also is on showing a fault but the tires are all inflated properly. My tire dealer checked the sensors (all OK) and tried to reset it but you need to use the remote to do it and, it cannot be done. Any thoughts on this problem?
