🔧 PRO TIP
The 2006 CLS (W219 chassis) runs the FBS3 immobilizer tied to the EIS/EZS module, part number 211 545 xx xx depending on build. The key is an infrared remote head key, FCC ID IYZ-3312, using a CR2025 battery. If the battery dies, the IR remote goes dead but the transponder still works, so the key will still start the car if you insert it. The remote just stops locking and unlocking. Swap the CR2025 before you panic.

2006 Mercedes-Benz CLS Replacement - Fast, Affordable & Professional

Got a call from a guy over near Topa Topa Brewing Company in Oxnard. His 2006 CLS500 had one working key left and the remote buttons had quit on it months ago. He had been manually inserting the key to start and using the door lock cylinder every day. Lived with it.

Then the plastic housing cracked and he started worrying about losing the transponder chip inside. Fair worry.

I pulled up, popped his old key open on the hood, and showed him the problem. The CR2025 was not just dead, it had leaked a little and corroded one of the battery contacts inside the 5WK47283 housing. That is why the remote died. The transponder side still worked because it is passive, powered by the EIS reader coil when you insert the key.

Cut a new remote head key blank, paired the transponder through the OBD port to the EIS module, and programmed the four-button IR remote. Lock, unlock, trunk, panic. Then I erased his damaged old key from the system so it could not start the car if someone found it later.

He stood there clicking the remote at the doors like he was rediscovering his own car. Said he forgot the trunk button even existed.

Whole thing took about 40 minutes on site. Way less than what the dealer wanted, and he did not have to leave the parking lot.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”

“Super fast service. About 20 minutes from the call he was already there. He had an authentic replacement on hand and made a spare key for my 2017 Nissan Rogue in about 15 minutes. Great prices, friendly, and very professional.”

Mercedes-Benz CLS Mobile Service FAQ

Real costs, no dealer surprises

Do I have to go to the Mercedes-Benz dealer to get a replacement key for my 2006 CLS?
No. The 2006 CLS runs the FBS3 immobilizer platform, and that system is fully serviceable by a locksmith with Mercedes-specific diagnostic tools. I read the EIS/EZS module through the OBD port, program the new transponder, and set up the IR remote on site. Dealers will order a pre-coded key from Germany by VIN, which adds days or weeks of wait time. For the FBS3 generation, there is no reason to go that route. I handle the whole job in one visit in Oxnard near Topa Topa Brewing Company.
