Lost your car key? Yeah, the cost is probably the first thing on your mind. Real breakdown of what you'll pay in 2026, depending on the key type and who you call.

Basic transponder key: dealer wants $150-250, a locksmith charges $120-180. These are the traditional turn-in-the-ignition keys with a chip inside. Common on Toyota, Honda, and Ford vehicles from 2000-2015.

Remote head key (key plus buttons): dealer charges $200-350, locksmith charges $150-250. This is what most people have. A key with lock/unlock/trunk buttons built into the top. You'll find these on most cars from 2010-2020.

Smart key or proximity fob (push-to-start): dealer charges $300-800, locksmith charges $200-320. These stay in your pocket and you press a button to start. Common on newer luxury and mid-range cars.

So why is the dealer so much more? They've got rent, staff, and service bays to pay for. They mark up parts because they only use OEM. And if your car is sitting in their lot, they know you're paying whatever they ask. A mobile locksmith comes to you, runs leaner, and has to compete on price.

At Locksmith Auto, every car key replacement includes: cutting the key for your vehicle, programming the transponder or smart chip, testing that it starts the car and all the buttons work, plus a 90-day warranty. Same day service, on-site, no towing needed. Call for an exact quote on your vehicle.
