Mazda Key Replacement in Santa Rosa, CA
5 models covered · Mazda Advanced Keyless Entry System · Mobile locksmith to your location
CX-5 is by far the most common Mazda in Sonoma County, especially around the Roseland and South Park neighborhoods. The Advanced Keyless Entry system works well, but dealer replacement keys cost more than they should for what you get. Newer CX-30 and CX-50 models use an updated rolling-code protocol. Our Autel IM608 handles it natively. A CX-5 owner near Luther Burbank Gardens needed a spare fob — cut the emergency key and programmed the fob in one visit, 25 minutes.
Select your Mazda 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.
