I lost one of my two keys and purchased a replacement. I've been able to program the key to the car using TS. I subsequently figured out how to program the seat memory position to the key using a button press sequence in the car.

Everything is working except when holding down the trunk button to open the trunk (no beep or anything). The proximity sensor works at all doors and the trunk. The door lock and unlock buttons work. Everything works on the old key, so I know it's related to the new key more than the car.

Is there something I missed in TS or a different procedure to activate the trunk button on the keyfob?

Thanks!
