2014 Mercedes-Benz Cl-Class Replacement - Fast, Affordable & Professional
Got a call from a guy near the Fillmore Towne Theatre in Fillmore. His 2014 CL-Class wouldn't turn over. Dash just sat there with "Key not recognized" and the steering lock stayed engaged.
He had already swapped the CR2025. Twice. Both from the same grocery store pack, which turned out to be fine. The problem was inside the key housing itself.
I popped the chrome key head apart on his trunk lid. One of the two battery contact springs had a hairline crack and wasn't making solid contact. The infrared transmitter in the key head was getting intermittent power, so the EIS module on the dash column would see the key one second and lose it the next. Classic symptom on these C216 keys with the IYZ-3312 FCC ID. The plastic tabs that hold the board get brittle after years of pocket carry and the internals shift just enough.
Transplanted the 5WK47283 electronics into a fresh housing, seated the contacts properly, dropped in a new CR2025, and tested. Steering lock released on the first try. Started clean. Ran all four buttons: lock, unlock, trunk, panic. Walked the perimeter checking range.
He had been reading forums about EIS module failure and was already mentally preparing for a dealer trip. Turned out to be a cracked spring in a ten-year-old key shell. He drove home ten minutes later, paid a fraction of what the dealer would have quoted just for the diagnostic appointment.
