🔧 PRO TIP
The 2004 Z4 (E85 chassis) runs the EWS3+ immobilizer paired with a CAS2 module, part number 61.35-6955750. The key is an HU92 sidewinder remote head with FCC ID LX8FZV and a CR2032 battery. All-keys-lost on these is bench work: pull the CAS2 unit from behind the glovebox, read the ISN and key data, then write a fresh key and sync it back. The whole job runs about 45 to 60 minutes including cutting the blade.

2004 BMW Z4 Remote Head Key Replacement - Fast, Affordable & Professional

Guy in the RiverPark neighborhood in Oxnard called me on a Wednesday night. He had just flown back into town, took the shuttle to short-term parking, and his 2004 BMW Z4 was completely dead to the fob. Pressed every button. Held it against the steering column near the EWS ring antenna. Nothing.

Doors locked, car sitting there like a paperweight.

He called the dealer. Earliest appointment was Friday. A tow out of the airport garage would have cost him on top of that. Two days without his car, minimum. He found EZ Car Keyz and I was there within 40 minutes.

Once I got the door open, I plugged my IM608 into the OBD port and pulled data from the CAS2 module. His key was still registered in the system but the CR2032 inside the LX8FZV fob had gone completely flat. The transponder chip was not getting enough juice to handshake with the EWS, so the immobilizer just sat there ignoring him. I replaced the cell, resynced the remote to the CAS2, and tested all three buttons plus the start sequence.

He stood there watching, arms crossed, doing that slow nod people do when they realize it was a small fix. I tossed him a spare CR2032 for the glovebox.

He drove home that same evening. His Z4 never left the parking space he pulled into a week earlier.

BMW Z4 Mobile Service FAQ

Real costs, no dealer surprises

How long does the BMW dealer take for a 2004 Z4 key replacement?
Longer than most people expect. BMW keys are VIN-matched and ordered through the dealer network. On older models like the E85 Z4, you are looking at 2 to 5 business days just for the key to arrive, sometimes longer if the part is backordered. Once it shows up, programming is typically quoted at 1 to 3 hours of shop time. The tech connects with BMW ISTA, runs a vehicle test, blocks any lost keys in the CAS2 module, and enables the new one. One forum member on Bimmerfest reported the full process taking nearly a week from first call to driving away. We skip all of that and handle it at your car.
