So here's an interesting problem for you guys: I've been driving my 2007 Cayman for 15,400 miles with no problems since new. Then Sunday morning I get in the car, and it won't start. The remote locks and unlocks, and the lights, radio, windows, A/C all work normally. I can turn the key ... but the car won't even crank over. Hmm. So I try turning the steering wheel ... check if it was locked. Nope. Car still won't start. Fiddle with the clutch, put it in gear, out of gear ... try all sorts of things. Still won't start. Call Porsche Roadside and the guy comes out to jumpstart the car ... nothing. Still won't crank. Off to the dealer we tow. The dealer tells me that both keys are "deprogrammed" -- the car was fine, but it wouldn't recognize the keys. The mechanic says this frequently happens when you try to start the car with a low battery. The computer just wipes out the key memory. And there's no way to prevent this from happening except to purchase a battery charger for use at home to keep it fully charged. This sounds a little off to me, and I decided not to buy the charger ... but has this happened to anyone else? It was covered under warranty, but still ... I'm just glad it happened in my driveway and not in some far off road trip pit stop. Cheers, Hoya

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Sounds plausible. But I'd not heard of it happening before. Did the dealer mechanic service your battery in anyway in addition to reprogramming the keys? If not then it wasn't much of a fix. However you don't want a battery charger but a battery maintainer (search for a bunch of threads on the subject). And I maintain that all Porsche owners should get in the habit of using them.
Doesn't sound like your keys, sounds more like it's on your vehicles end if anything. I've had my battery fail because I failed to drive it often and even customers who have actually flatted their vehicles in due to a dead battery but the transponders were fine. Hummmm.... :crazy:
This will sound weird but any chance both keys were on or near the microwave? They keys for our Lincoln once got wiped out by being left on top of the microwave.
