2003 Mercedes-Benz SLK Remote Head Key Replacement - Fast, Affordable & Professional
Got a call from a guy at Ventura Promenade who said his 2003 SLK just stopped starting. Engine cranked, dash lit up, but nothing caught. The red key symbol stayed on solid.
He had already looked it up online and was convinced his EIS module was dead. Told me he found forum threads about people replacing the entire EZS unit and needing it shipped from Germany. He sounded like he'd been reading MBWorld posts for two days straight.
I got there and pulled the key apart on his trunk lid. The IR window on the fob housing was clouded over, almost opaque. Years of pocket lint, hand lotion, and general wear had basically blinded the infrared emitter. Cleaned it, tested the signal output, and it was reading again.
Put the key back in the EIS slot. Red key icon flickered once, went off, and the M111 turned over clean. He sat in the driver's seat for a second and just shook his head.
The other thing I noticed was his CR2025 was low, about 2.7 volts. Swapped it while I was in there. Tested both the lock and unlock plus the trunk release on the four-button remote, all responding.
Whole thing took maybe twenty minutes. He had been quoted a multi-week wait at the dealer to diagnose and potentially replace the EIS. Saved a good chunk and got back on the road the same afternoon.

“My ignition would not turn in La Jolla and I thought I needed a tow. EZ Car Keyz repaired the ignition on the spot and also made a spare key for safety. The technician worked carefully and confidently.”
“Niv showed up, did his thing, and just like that I had two new keys for a fraction of what the dealership quoted. I have zero reservations recommending him to anyone who needs car keys replaced.”
“We had one broken key for our Honda Civic and one working key for our Lexus. Tim came out and cut three remote car keys at a great price. All keys worked perfectly. Professional, courteous, and highly recommended.”
