Key Replacement - Save vs Dealer in Ventura County

2003 BMW Z4 Remote Head Key Replacement - Fast, Affordable & Professional

I got a call from a guy parked at The Collection in Oxnard, right outside the REI. He'd been clicking his 2003 Z4 key from about three feet away for ten minutes and nothing was happening. Locks weren't responding, no flicker on the mirrors, nothing.

He'd already been to the dealer. They told him the key needed to be replaced, that it was a BMW-only job, and that he'd need to leave the car. He called me because a coworker mentioned my name.

When I pulled up, he handed me the fob. CR2032 was still in there from whenever he last replaced it. I popped the housing and the battery had walked sideways, just barely off the contact. The kind of thing that happens after the key lives at the bottom of a gym bag for a year.

Seated the battery, closed the housing, walked back to the car. Locks worked from across the parking lot.

He stood there quiet for a second. Then he said something like "so I didn't need to go to the dealer at all."

Not for that one, no. Sometimes it's that simple. I told him if the fob had actually failed or he'd lost the key entirely, programming a replacement for the Z4 does require real tools connected to the immobilizer, and that's still a job I do on-site, not at a dealer. But this visit took maybe eight minutes and he was back to his lunch.

That's the part of the job nobody talks about: knowing when the answer is small.
