2003 BMW M3 Remote Head Key Replacement - Fast, Affordable & Professional
Got a call from a guy near the Fillmore Towne Theatre around 11 at night. His 2003 M3, the E46 with the S54, was sitting in his driveway and the only key he had just stopped turning past position two. Engine crank, nothing. Dash gave him the EWS tamper dot, that little yellow car-with-a-key icon.
He had already called the dealer earlier that week. They told him to tow it in during service hours and quoted him a wait of almost two weeks for a new key order plus coding. He figured the car was stuck until then.
I drove out to Fillmore with a replacement remote head key blank, part number 6955750, already in my kit. Connected to the OBD-II port, pulled the EWS3 module data, read the ISN sync between the EWS and his MSS54 DME, and wrote the new PCF7935 transponder to an open key slot. Cut the HU92 blade on my mobile machine using the code from the EWS dump.
The part that made the job feel real was when he turned the key and the S54 caught. He just sat there with his hands on the wheel for a second, not going anywhere, just listening to it idle. I get that. That inline six at idle sounds like money.
Whole thing took about 40 minutes on a dark street. No tow, no two-week wait, for way less than the dealer quoted him.

What quick turnaround sounds like
“This is the only locksmith anyone should ever call. I am still shocked at how fast he arrived and the price was hundreds less than other quotes I received. Honest, professional, and extremely efficient.”
“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
