Some stories from way back last summer:
- A colleague of a smart owner told the latter that the car was acting out in the company's parking: he had the key in his pocket and was locking/unlocking his car at almost every move, through the walls.
- A father was asking lots of question about his key/fob not working anymore: his toddler had played with the buttons and went past the car-fob memory. They required a Dealer's visit for a reset/re-match.
- Someone posted about the round button on the fob getting loose and using some thin plastic/rubber material to patch it up. Those are somewhat delicate. TLC!
I've heard that a set of new keys costs $300 and is available only through a Dealership... Be careful!
Suggestion: switch key now and then, to give them both a chance to refresh their handshake with the car's ECU.
