The dealer reflashed the alarm computers and all issues went away. Locks and unlocks work as expected too. I made another post with More details.
Hey guys,
2015 981 boxster s, 33k miles, upgrades include Porsche dealer installed plenum, pse, throttle body. Recently had door panel adhesive because they were departing, and installed k&n filters myself.
The other day I opened the trunk and the alarm activated. Nothing heavy inside. When I pressed the remote unlock, the car unlocked. When I pressed the lock, the vehicle locked. The alarm was activated the whole time. I drive home with the alarm activated--beep, beep, beep--for 30 seconds, a 10 second break, and then again.
Called the dealership and they had no explanation. Eventually, the alarm stopped after cycling over a dozen times.
Now, the trunk, frunk, and door locks no longer function from inside the vehicle, whether if it's off or on.
The panic button, trunk, and frunk on the remote still functions. I replaced the battery. When I reconnected the alarm again activates.
