🔧 PRO TIP
The 2003 BMW 3 Series is an E46 body, and the key setup is a remote head key with a 3-button fob and a CR2032 inside. The immobilizer on these is tied to the engine control module and the ignition, so the transponder chip in the key head has to be enrolled to the car, not just cut. That enrollment happens over the OBD port with BMW-capable equipment. What trips people up: a dead CR2032 kills the remote functions but the car will still start if the transponder side is healthy. So if your locks stopped responding but the car fires right up, swap the battery first before assuming the key is bad. The contacts inside the fob housing on these get corroded too, especially on a 20-year-old unit. Pop the back, clean the battery contacts with a pencil eraser, seat a fresh CR2032, and test before calling anyone.

2003 BMW 3 Series Remote Head Key Replacement - Fast, Affordable & Professional

I got a call from a guy parked near the Peach Hill area of Moorpark. He had been using his 2003 BMW 3 Series key for years and the blade had finally given up. He could feel it flex when he turned the ignition, and one morning it just would not come back out cleanly. The blade was worn thin at the tip and the bow was starting to separate from the head. He was afraid to pull hard and leave the blade stuck in the cylinder.

He found me and I came out to him.

I decoded the lock from the door cylinder, which still had clean wafers and gave me a solid read. Cut a fresh blade on my machine, assembled it into a new key head with a fresh battery, and enrolled the transponder to the car through the OBD port using my BMW-specific tooling. The whole thing from decode to first start was just under an hour.

He asked me what the dealer would have quoted. I told him to call and find out. He laughed and said he already knew it would involve leaving the car for a few days. It did not need to be that complicated.

The key he drove away with works cleaner than the worn original ever did in the last year of its life.

“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”

“My key fob stopped working while I was at Oxnard Harbor and I thought I was going to need a tow. EZ Car Keyz showed up fast, programmed a new fob, checked everything carefully, and made sure the car was fully functional before leaving.”

BMW 3 Series Mobile Service FAQ

Real costs, no dealer surprises

Are you licensed and insured to work on BMW vehicles?
Yes. EZ Car Keyz is licensed through the California Bureau of Security and Investigative Services, which is the state body that regulates automotive locksmiths. We carry full liability insurance. For a 2003 BMW 3 Series, the job touches the immobilizer and the OBD port, and you want someone credentialed and insured handling that, not a guy with a generic key machine and no documentation. Ask any locksmith for their BSIS license number before they touch your car. We give it freely.
How do I know you are not a scam locksmith?
Will the replacement key work exactly like the original?
My 2003 BMW 3 Series starts fine but the remote stopped working. Do I need a whole new key?
I bought a replacement fob online for my 2003 BMW 3 Series. Can you just program it for me?
