BMW Key Replacement in Santa Rosa, CA
5 models covered · BMW EWS/CAS/FEM Immobilizer + Comfort Access · Mobile locksmith to your location
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.
