2011 Mercedes-Benz R-Class Remote Head Key Replacement - Fast, Affordable & Professional
Got a call from a guy near San Buenaventura State Beach in Ventura. His 2011 R350 had one working key left and the chrome was peeling off the fob so bad a chunk of the case had cracked open. He said the remote would only work if he squeezed it a certain way, like cracking a walnut.
I pulled up and he showed me. He had the thing pinched between his thumb and two fingers, held it toward the car, and clicked. Doors unlocked. He let go of the pressure and nothing. The CR2025 was fine. The board inside, the 5WK47283, had a hairline crack near the battery terminal pad. Flexing the case was the only thing that kept the contact alive.
Didn't try to repair that board. Cut a new HU64 blade on the van, paired a fresh IYZ-3312 fob through the OBD port to his NEC EIS module, and registered it into an open key slot. The W251 supports eight slots, and he only had one used, so plenty of room. Tested lock, unlock, trunk, panic on all four buttons, then started the engine twice to make sure the immobilizer handshake was solid.
He kept the cracked fob in his hand for a second like he was going to try it one more time out of habit. Then tossed it in the cupholder.
Whole thing took about 40 minutes. Way less hassle and money than the dealer route he had been dreading.

“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.”
“Very professional and extremely affordable. The price was literally about three times cheaper than what my dealership quoted me. Fast service and no stress at all. Highly recommend.”
“A friend lost my Lexus key and he was able to program and cut a brand new one within 20 minutes. Arrived within about 40 minutes and was friendly, efficient, and quick.”
