When you purchase this service, we'll pair up to 4 fobs to your immobilizer.  Although this can be done in the car, it can be tricky, and some 993's have hardware issues that prevent programming.  Here’s how it works:

1. After placing your o rder, we’ll contact you with shipping instructions.   
2. Mail us your immobilizer, fobs, and 4-digit immobilizer PIN CODE.  If you can't find your PIN CODE and can’t obtain it from a Porsche dealer, we can retrieve it using our PIN code recovery service.
3. When we receive your shipment, we'll program your fobs and return your immobilizer, ready to use.
