Absolutely LOVE the car, but... recently the inside Trunk Release Button quit working as well as on the key remote. Any ideas of what might be going on?

 

Check the latch mechanism in the trunk.

 

^^^agree with above (Decklid Release Solenoid) ^^^

The remote keyless entry system allows locking and unlocking of vehicle door(s), deck lid release, and panic by remote control using a hand held radio frequency transmitter. The vehicle must be in PARK before the trunk lid can be unlatched with the transmitter.

The receiver may receive signals from up to four transmitters. Each transmitter has its own code, and the code is programmed and stored into receiver memory. If a transmitter is replaced or additional transmitters are added, the codes for all units have to be reprogrammed into the receiver memory. If a receiver module is replaced, the transmitter codes must be stored in the new receiver memory.

The Deck Lid release button changes from a default “press twice” actuation to a “press and hold” (for approximately one third of a second) default. Note that this is customer programmable to “no delay” if so desired.
