2012 Mercedes-Benz R-Class Remote Head Key Replacement - Fast, Affordable & Professional
Got a call from a guy near Grant Park in Ventura. His 2012 R-Class R350, parked in the driveway, would not respond to any button on the fob. No lock, no unlock, no trunk. He tried holding it against the door handle. Nothing. Then he dug out the emergency blade, got the door open, and the alarm went off and would not stop until he got the key near the steering column and hit the start button.
He figured the CR2025 was dead. Swapped it. Same behavior.
When I got there, I pulled the key apart on his hood. The board inside, stamped 5WK47283, had visible corrosion traces around two of the micro-solder points near the NEC chip. His wife had run a pair of pants through the wash with the key in the pocket about a month earlier. He wiped it off, thought it was fine.
I cleaned the board contacts, replaced the CR2025 with a fresh one seated correctly, and reassembled the shell. Then tested all four buttons, the emergency blade in the door cylinder, and the EIS recognition at the steering column. Every function came back.
He had already called the dealer in Calabasas. They told him to tow the car in, leave it, and they would diagnose whether he needed a new key or a new EIS module. Could be days. He just needed a tech who would open the fob first.
