Fast Car Key Replacement — We Come to You
Losing your car keys is one of the most stressful situations you can face. Whether you misplaced your only key, had it stolen, or it simply broke in the ignition, 770 Locksmith is Orange County's trusted mobile car key replacement service. We dispatch immediately and arrive in 15–30 minutes — no towing required, no waiting at a dealership for days.
Our licensed California locksmith (Lic# LCO8612) carries professional key-cutting machines and programming equipment for virtually every vehicle make and model sold in the US. We serve all cities across Orange County, from Irvine and Anaheim to Newport Beach, Huntington Beach, and everywhere in between.
Types of Car Keys We Replace
Modern vehicles use several types of keys, each requiring different tools and expertise. 770 Locksmith handles them all:
Transponder Keys
Transponder keys contain a small chip inside the plastic head that communicates with your car's immobilizer system. If the chip is not programmed, the car will crank but not start. We cut the key blade to match your locks and program the transponder chip to your specific vehicle — all on-site. Transponder keys are used in most vehicles made after 1995.
Smart Keys & Proximity Fobs
Smart keys (also called proximity keys or keyless entry fobs) allow you to start your car without inserting a key. These are standard on most vehicles made after 2010. We program smart keys on-site using OEM-level diagnostic equipment. Smart key replacement through 770 Locksmith is faster and more convenient than visiting a dealership.
Push-to-Start / Ignition Fobs
Push-to-start vehicles require a programmed fob within range of the car's sensor. We supply and program push-to-start fobs for all major brands including Toyota, Honda, Ford, BMW, Mercedes-Benz, Hyundai, Kia, Lexus, and more. We can replace a lost push-to-start key even if you have no remaining working keys.
Duplicate / Spare Keys
Spare keys are the best insurance against lockouts. We cut and program duplicate keys while you wait — a process that takes under 30 minutes in most cases. Having a second programmed key saves you hundreds of dollars if your primary key is ever lost or damaged.
Key Fob Replacement & Programming
Has your key fob stopped working? Before buying a new one, let us diagnose it. We replace batteries, reprogram lost pairing, and supply new OEM-compatible fobs for all vehicles. We can also program additional remotes so every driver in your household has a working fob.
