Three generations of immobilizer: EWS (2000–2004), CAS (2004–2017), FEM/BDC (2018+). Each needs different programming. The West End and Santa Rosa Plaza area have a lot of BMWs. The SF dealer on Van Ness quotes $400–$600 for a replacement. We do the same Comfort Access key on your driveway for $280–$320. Had an X3 owner near Juilliard Park who needed two spare keys. Both done in 35 minutes. Same chip, same function, you skip the tow.

Select your BMW model below for specific pricing, supported key types, and year coverage. Every service includes key cutting, programming, and on-site testing — backed by our License #LCO8530 license and $$1,000,000 insurance.

What BMW Owners Ask Us

Real questions from BMW owners in Sonoma County — not generic templates.

BMW Comfort Access stopped recognizing my key when I stand near the door. Why?
The low-frequency antenna in the door handle may be failing, or your fob battery is low. Replace the CR2450 battery first. If it still fails, we can re-pair the Comfort Access link between the fob and the CAS module on-site. Call (707) 775-7069.
Can you program a BMW key without the original?
Yes. All-keys-lost BMW programming requires reading the ISN code from the CAS or FEM module. Our equipment handles EWS, CAS3, CAS4, and the newer FEM/BDC platforms. We do it at your location. Call (707) 775-7069.
