2013 Mercedes-Benz SL Remote Head Key Replacement - Fast, Affordable & Professional
Got a call from a guy over in Hollywood Beach, Oxnard. His 2013 SL550 was sitting in his driveway and the key would not turn over the EIS. Dashboard just showed "Key not recognized" and sat there. He had already swapped in a fresh CR2025. No change.
I pulled up and he handed me the fob right away, almost like he was done with it. Popped the shell on my tailgate. The battery was new, he was right about that. But the NEC chip underneath had a thin film of green corrosion across two of the contact legs. He lives three blocks from the beach. Salt air does that quietly.
Cleaned the PCB contacts with isopropyl and a fiberglass pen, checked the infrared emitter window on the key, reseated everything. Slid it back into the EIS and the cluster lit up clean. No codes, no drama.
Then I tested the full loop: all four buttons on the IYZ-3312, trunk release, remote start sequence, panic, and the mechanical blade in the driver door lock. Everything responded like it should.
He said he had already called the dealer in Encino and they told him two to three weeks for a replacement key to come from Germany, plus the programming appointment after that. He was looking at being without his car for almost a month. Instead, he drove it to dinner that night.
