I have a 2015 Boxster and have recently had problems with the Key FOB. Sometimes the FOB does not work to lock the door after I exit. The LED flashes but no luck. If I sit inside and use the FOB to lock or unlock, it works fine. I get out and try to lock -- no go. I have tried starting the car and even driving it a few feet to get out and try again. But it does not lock. During these moments, the trunks don't open either with the FOB. After driving home it works fine and might continue to do so the next 50 times I am on the road. But then randomly the problem starts again.
I have taken out the FOB battery and it is at 3.1v.
Any suggestions?
