My Key/remote alarm packed up at the weekend! I cant operate the alarm/doors with it, and cant turn the alarm off once inside, slightly embarassing! The key has power by the looks of the red light and long recent drive. I was told some keys have to be synchronised, is this the case with this problem or do i need a new key/remote alarm from porsche?

 

Probably just needs to be reprogrammed. They sometimes lose their programming for no obvious reason.

 

Boxter Remote Key problem: I note that my remote key is struggling to work and only after many attempts. Both keys have same issue. Fresh battery , not sleep mode, and have resynced the codes by using the remote within 6 seconds of key in and key out of ignition, reversed polarity of battery also.
HOWEVER : i have found that both keys work perfectly if I open the remote casing and use the remote out of the casing.
Any suggestions
Thank you
