Car key replacement for 36+ brands — mobile service across Santa Rosa and Sonoma County from $120.
Car Key Replacement in Santa Rosa, CA
Lost your car key? Need a spare? We cut and program replacement keys for 36+ brands and 160+ models — on-site, same day, at your location.
Car keys stopped being simple metal blanks about 20 years ago. Your key has a chip inside it now. If that chip is not programmed to your car, the engine will not start even if the key turns. We carry an Autel IM608 programmer, a Miracle A9 key machine, and blanks for 36 brands in the van. We drive to you anywhere in Santa Rosa — Railroad Square, Rincon Valley, Fountaingrove, Bennett Valley — and every city in Sonoma County.
Select your vehicle brand below for specific models, key types, and flat-rate pricing. Every job includes precision cutting, transponder or smart key programming, and full testing — backed by our BSIS License #LCO8530 license and $1,000,000 insurance.
