2000 Mercedes-Benz SL Remote Head Key Replacement - Fast, Affordable & Professional
Got a call from a guy in Lower Village, Montecito, standing next to his 2000 SL500 in a restaurant parking lot. The key turned, the starter cranked, but the engine would catch for half a second and die. Classic immobilizer behavior on these R129s. The EZS module was seeing the key mechanically but not reading the transponder chip.
He had already called the dealer. They told him it would need to be towed in and they could look at it in three to four days. He was not thrilled.
I drove out and pulled up the EIS data through the OBD port. The key's transponder ID was still stored in the module, but the signal was weak. Opened the fob and found the problem: corrosion on one of the battery contacts had crept close enough to the transponder coil connection on the board to mess with the signal. Cleaned it, replaced the CR2025, reassembled, and re-seated the key in the ignition.
Fired right up. No new key needed.
He stood there for a second with his hand still on the door, like he was waiting for it to stall again. It did not.
The whole thing took about twenty minutes. He kept his car, kept his afternoon plans, and spent a fraction of what a tow plus a dealer diagnostic would have run him.

Fast Keys, Happy Customers
Quick service that speaks for itself
“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”
