Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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.

POST 1 / ORIGINAL POSTEROriginal post

What can I expect to pay for an additional key for a 99 996? Do the keys have batteries that fail over time? Thx.

POST 2Original post

Keys do have batteries that need to be replaced every couple of years. You'll need your dealer to order the key blank, cut it and program your car to accept the key. I haven't yet had to purchase one, so I can't tell you exactly what you'll pay, but it will be in the $300+ range.

POST 3Original post

Try replacing the battery first. If that doesn't work it may be the circuit board. The blade part will still be good If you just want an "extra" key get a valet key(no remote function) cheaper!

POST 4 / ORIGINAL POSTEROriginal post

Thx for the insights guys.

POST 5Original post

Mine cost $300. When the batttery failed on my second key recently, the Porsche dealer replaced it for me for free. Not really, I recently had spent around $6500 there so they did not charge me an extra dime. I suppose they figured I had recently paid for it.

POST 6Original post

Rreplaced the battery, or the whole key?

POST 7Original post

Sorry, I should have specified. They replaced the battery for no charge. But I just found that the new battery is dead in less than 1 week since they replaced it. Now I am woried that the key electronics may have a problem. Or they put in an old battery, maybe why it cost me nothin?

POST 8Original post

Buying a new key and getting it to work is a three part process. The cheapest way I found to get a replacement key was to: 1. Buy the keyhead on ebay ($129) make sure its new and comes with code tag. 2. Bought key blanks (2) and had them cut by a guy in England (Ebay) He cuts it from a picture of your original key, worked great! ($35.00). 3. Get it programmed from dealer, was $75 here in Alabama. This cost varies according to which stealer you work with. Total cost $239.
