Can you reprogram a 987.1 key for a 997.1 cab?


Recommended Posts

I bought a new key for my 987.1 a while back. It's one of the new style keys and I like it much more than the originals which felt pretty cheap to me. Anyways, I am selling the 987 and buying a 997.1 cab. My question is, can the 987 key be "reprogrammed" for thd new car?

The key was not cheap and I'd like to keep it for the new car.

Thanks in advance,

Jason

You should be able to get the car reprogrammed to the key with a PIWIS tester. The 9x7 procedure for reprogramming reads the radio frequency from the key head. Obviously, you will need to buy a new blade.

Great, thanks. Just to confirm, the buttons on the key head are the same for the 987 Boxster and the 997 cabriolet, right?

I would imagine the 987 key is 3-button, and the 997 Cab a 2-button, but I'm not sure. I would think that if the 3-button remote is programmed to a "2-button car" then the 3rd button would do nothing. During programming, you only press the door lock button, which would be the same for both. One would assume that the front lid button would be coded the same on both key types.

Spoke with a tech and he said that it's not possible to "undo" the programming of a key. He said that once it's mated to the car you cannot un-mate it. Guess I'll have to spring for a new key. :cursing:

I'm not sure that is correct. When you program the alarm module on a 9x7 for new keys, you start the process from scratch. First step is to specify the number of keys you are programming, and then you insert the first key in the ignition, switch on, press the remote button, and then remove it. Then insert the second key and repeat, until you have programmed them all. It doesn't matter what order you do it, so you are effectively programming pre-used keys to the car. For each key it reads the signals from the remote itself. It isn't like the older 9x6 system, whereby the remote code was entered manually from the tag on the new key, into one of the key registers on the alarm module.

Does that mean we don't need to input any codes into the piwis for this procedure anymore?
