Transponder & Car Key Replacement

Lost your car key or need a spare? Our mobile locksmith cuts and programs transponder keys, smart keys and remote fobs in Hardeeville for most makes and models - on site and usually far cheaper than the dealer.

Transponder and chip key replacement

Most modern car keys contain a transponder chip that must be programmed to your vehicle before it will start. We carry the equipment to cut and program these chip keys on site, so whether you have lost your only key or simply want a backup, we can make one at your location without a costly tow to the dealership.

Smart keys, fobs and remotes

Push-to-start vehicles use proximity smart keys, and many cars use remote head keys or separate fobs for locking and unlocking. We program proximity smart keys and remotes for a wide range of vehicles, restoring keyless entry and push-button start so you are not left juggling a mechanical backup key.

Made on site, priced fairly

Dealerships often charge a premium and require an appointment and a tow. As a mobile locksmith, we come to you - at home, at work, or wherever your car is parked - and typically complete the job for less. Want to know what your specific vehicle uses? Our car key replacement by make & model guide breaks down key types and programming for the major brands. Call (843) 350-1700 with your year, make and model and we will confirm what is possible and what it will cost.

A spare key is cheaper than an emergency

The most expensive time to make a car key is when you've lost the only one and you're stranded. Cutting and programming a spare while you still have a working key is faster, cheaper and far less stressful. If you're down to a single key, or you just bought a used car that came with only one, let us make a backup now - you'll thank yourself the day the first one goes missing.

Transponder, smart key or basic key - what's the difference?

It helps to know which type of key your car uses. A basic, older key is purely mechanical - cut metal, no chip - and can be copied cheaply because the car has no electronic check. A transponder key looks similar but hides a chip in the plastic head that the car must recognize before it will start, so it has to be programmed, not just cut. A smart key, or proximity fob, takes it further: you keep it in your pocket and start the car with a button. Newer vehicles almost always use transponder or smart keys, which is why a plain hardware-store copy will open nothing and start nothing on its own.

Why a programmed key costs more than a cut copy

If you've only ever paid a few dollars for a spare house key, the price of a car key can be a surprise - so here's the honest reason. A modern car key isn't just metal; it's a programmed electronic device. The price reflects the chipped blank or fob itself, the equipment to cut it precisely to your vehicle, and the labor and security access to pair it with your car's computer so it will actually start the engine. It's still typically well below dealer pricing and saves you a tow, but it's a genuinely different job from copying a plain key - and that difference is what you're paying for.
