2004 Mercedes-Benz SLK Remote Head Key Replacement - Fast, Affordable & Professional
Got a call from a guy over near Ventura Music Hall. His 2004 SLK320 had one key left and the remote buttons were dead. Lock, unlock, trunk, panic, nothing. He'd been using just the blade for weeks, manually locking the doors like it was 1985.
He told me he called the Mercedes dealer first. They wanted the car towed in, said they'd need to order the key blank from Germany by VIN, and quoted him a timeline of two to three weeks. He said he just hung up.
I got there, popped the old fob shell open on his hood. Classic story. The CR2025 had leaked just enough to leave a green film across one of the battery contact pads and along a trace near the IR LED. The NEC chip looked fine, but that corrosion was killing the signal before it ever left the fob.
Cleaned the board with contact cleaner, checked continuity on the traces, dropped in a fresh CR2025, and tested IR output. Buttons came back. All four. Then I connected to the EIS through the OBD port to confirm the transponder side was still registered and the key ID showed active in the slot.
He sat on the curb the whole time watching. When the trunk popped from the button, he just nodded like he'd been waiting a month to see that happen. He had.
Whole thing took maybe twenty minutes. No tow, no parts order, no three-week wait.

“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”
“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.”
