Quick 2010 Mercedes-Benz R-Class transponder key cut by EZ Car Keyz Ventura CA
🔧 PRO TIP
The 2010 R-Class runs a NEC-based EIS/EZS module (part number range A164 545 XX XX) with infrared and transponder authentication. Your IYZ-3312 remote head key holds a NEC chip on the PCB inside, and it talks to the EIS before the engine will crank. If the key turns but the dash stays dead, don't blame the key first. The W251 shares the ESL electronic steering lock issue with the W204 and W212. That motor locks up internally, throws a steering lock malfunction message, and mimics a dead key perfectly.

2010 Mercedes-Benz R-Class Remote Head Key Replacement - Fast, Affordable & Professional

Got a call from a guy near Cross at Grant Park in Ventura. His 2010 R350 had one key left, and the chrome shell was cracked right at the hinge where the blade meets the head. He'd been holding it together with electrical tape for a few weeks, but that morning the blade snapped clean off inside the ignition slot.

He was standing next to the car with the electronic head in one hand and nothing in the other.

I pulled the broken blade out of the EZS slot with extraction hooks. Took about two minutes. The good news was his original PCB and NEC chip were fine inside the cracked housing. So I moved the board into a new aftermarket shell, cut a fresh HU64 blade to match his door lock decode, and tested IR communication with the EIS.

Key turned, dash lit up, engine started on the first try. Then I walked the four buttons on the remote: lock, unlock, trunk, panic. All clean response.

The part that made me laugh was him peeling the electrical tape off the old shell and just staring at it. He said he'd been driving around like that for three weeks and kept telling himself it was fine.

He asked what the dealer would have charged. I told him it would have been a lot more, plus a tow, plus waiting for a part order. He just nodded.

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Mercedes-Benz R-Class Mobile Service FAQ

Real costs, no dealer surprises

My key blade broke off in the ignition. Can you get it out and make a new one?
Yep. Broken key extraction on the W251 R-Class is a standard call for me. I use pick-style extraction tools to slide the broken HU64 blade fragment out of the EZS slot without scoring the wafers. Mercedes chrome key shells are known for cracking at the hinge casting, especially once they hit the 10-plus year mark. Owners on MBWorld report the same failure: blade just snaps one day. Once the piece is out, I can cut a new blade and transplant your original PCB and NEC chip into a fresh shell if the electronics still test good. If the board is damaged, I cut and program a full replacement on site.
What exactly is the remote head key on my 2010 R-Class?
My Mercedes says "key not detected" or won't start. What should I try first?
Can I buy a key online and program it myself to save money?
My steering wheel is locked and the dash says "steering lock malfunction." Is my key bad?
