The credit for this goes to Kendo on 986forum, but I thought it might be worth posting in the DIY section here. I tried it and it worked for me. Kendo: For those that have just had the tactile switch fail and want to replace it it can be found at Mouser Electronics for $0.60 each.

I just purchased a 1999 Boxster. The door locks work fine with the key and the dash toggle switch. However the key lock swicth on neither of the keys works, and both have fresh batteries and I can see the LED turn on when I press a button. I know that the battery has been drained at some time before I bought it and I have removed the battery to run some new radio wiring.

 

From searching online it looks like there is a system in the car to pair the keys and car. I tried one process I found to unlock car, turn on ignition, turn off ignition, hit lock key. No joy.

 

Any suggestions?

The only way to match the keeps to the car (immobilizer) is with a Porsche diagnostic tool (i.e. PST2. PIWIS, or PIWIS 2) and your car's IPAS codes.

Thanks. So from what you said the dealer is only person who can do this.

 

How do I get the IPAS codes

As stated here before... you can only get IPAS codes from Porsche through a dealer/OPC.

If a Porsche dealer/OPC does the work they have access - if a 3rd party shop does the work they will need you to get your IPAS codes from a dealer/OPC.

These codes should be free - some dealers/OPCs may be reluctant to give them to you - if so then find another dealer/OPC. Protect the codes as they are what is needed to forge keys.
