2003 Mercedes-Benz E-Class Remote Head Key Replacement - Fast, Affordable & Professional
Got a call from someone stuck near Community Memorial Hospital in Ventura with a dead 2003 E320. No working key. He had one SmartKey that stopped turning the ignition about a week prior, and instead of dealing with it, he had been using a second key. That morning the second key quit too. Dashboard lit up with the steering lock warning and the car would not crank.
He already called the dealer. They told him to tow it in, order a new key from Germany, and wait. Weeks, probably. He was parked in a lot near the hospital visiting a family member and just needed the car running.
I pulled up, connected to the OBD port, and identified the EIS. His was the NEC-based board, which is the more common variant on 2003 builds. Read the module, calculated the key data, and programmed a fresh SmartKey into an open slot. Cut the blade on the van to match the HU64 lock profile.
The part nobody thinks about: I tested both the infrared link and the mechanical turn in the ignition, then cycled the locks and all four remote buttons. The steering lock released clean on the first try.
He sat in the driver's seat and just held the key in his hand for a second before turning it. That quiet moment where it sinks in that the car works again. He drove out of the lot same day, no tow truck, no waiting on a shipment from Stuttgart.

“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.”
