1998 Mercedes-Benz SL Remote Head Key Replacement - Fast, Affordable & Professional
Got a call from a guy near the Santa Susana Depot Museum in Simi Valley. His 1998 Mercedes-Benz SL had been sitting in a friend's garage for a few weeks after his keys were stolen at a car show. He wasn't panicking about getting a new key. He was panicking about someone showing up with the old one.
Fair concern. On these R129 SLs, the immobilizer runs through the EIS module, and any previously programmed key will still start the car until you wipe it. So this wasn't just a key replacement. It was a full reset.
I plugged into the OBD port, connected to the EIS, and cleared every stored key from the system. Then I cut and programmed his new remote head key as the only authorized transponder. The old stolen key? Dead. It won't even turn the ignition anymore, let alone get past the immobilizer.
He wanted a spare too, which is smart. I programmed both in the same session so the module recognized two keys and nothing else.
The part that stuck with me was him just sitting in the driver's seat afterward, locking and unlocking the doors over and over with the new fob, watching the IR receiver blink back at him. He said he hadn't driven the car in three weeks because he didn't trust it.
Whole thing took about 40 minutes in the driveway. A dealer would have wanted the car towed in and a week of waiting.
