I had been out of town for a week, and unable to drive my Boxster.
Last night, I went into the garage and there it was, waiting for me to drive it. The alarm light was blinking as usual.
I pressed the door unlock button on my key and the light on the key fob light up bright red, but nothing happened... no alarm disarm, no unlocked doors, etc.
After repeated attempts, I put the key in the door, manually unlocked the car and put the key in the ignition. Started fine.
Then I killed the engine, removed the key and tried it again... worked fine, and continued to work fine for the next two hours.
Anyone had this problem and know the source?
