2011 BMW Z4 Replacement - Fast, Affordable & Professional
I can make a key for your 2011 BMW Z4 with no original. No spare needed, no existing key. I build one from the car's own security data. All-keys-lost on BMW is more involved than other brands because the immobilizer modules are heavily encrypted, but it's a field job I do regularly with the right tools.
A customer at the beach cliff lot near South Poway lost his only fob somewhere on the trail. He searched for 40 minutes and came up with nothing. His Z4 was sitting in the lot with no way to open it. I told him I could be there that afternoon and have him driving home the same day.
I started with my HU92 Lishi to pick his door open and decode every wafer position for the blade cut. For AKL on BMW, I also need to access the CAS module. I read the CAS3 data through OBD, extracted the ISN from the DME, calculated a new key slot, and programmed the fob. His smart key, FCC ID , was a 3-button slot fob that started the car on the first try.
His car started in the same beach cliff lot. Total was around $95. Dealer would have been roughly $200 plus a tow and a multi-day wait. The whole process from lock decode to engine running took about an hour. BMW all-keys-lost takes longer than a simple spare because of the CAS module read and ISN sync, but with the right tools it's still a mobile job on most CAS-era models.
