Car Key Duplication From $75 — mobile automotive locksmith in Santa Rosa, CA.
Car Key Duplication in Santa Rosa, CA
Need a spare car key before you lose the only one? Smart move. We cut and program duplicate car keys on-site.
Types of car keys we duplicate
Basic metal keys (older vehicles), transponder chip keys (most cars 2000+), high-security sidewinder keys (Honda, Toyota, Ford), and smart proximity fobs. We cut the key to match your existing key or decode the lock directly. The transponder chip is programmed to your car so both keys start the engine. We have done duplicates for everything from a 1995 Ford Ranger in Cloverdale to a 2024 Tesla Model 3 in Healdsburg.
Why you should get a spare key now
Losing your only car key means an "all keys lost" job — we have to decode the lock, cut a new key, and reprogram the immobilizer from scratch. That costs $200 to $400. Had a customer in Cotati who lost her only Honda key at Sonoma State University. That turned a $100 spare into a $350 emergency. A duplicate made while you have a working key costs $75 to $175.
