Car Key Replacement & Key Fob Programming

Most vehicles built in the last two decades use transponder keys or remote fobs that have to be electronically programmed to your car's immobilizer system, not just cut to shape. Highland Lakes Lock & Key cuts and programs replacement keys and fobs on-site for a wide range of makes and models, often at a lower cost and shorter wait than a dealership.

Transponder keys, fobs, and smart keys

A transponder key contains a small chip that communicates with your car's immobilizer; without the correct chip programmed to your vehicle, the engine won't start even if the key physically turns. A key fob adds remote locking, unlocking, and sometimes remote start. A smart key or proximity key goes a step further, letting the car detect the key nearby and unlock or start with a push button. All three require specialized programming equipment that reads and writes to your vehicle's onboard systems — equipment our technicians carry in the field.

If you still have a working key or fob, we may be able to cut and program a spare without needing anything from the dealership. If you've lost every key to the vehicle, we can often still create a new key from scratch using your vehicle's identification number and applicable security procedures, depending on make and model.

Frequently asked questions

How much does it cost to replace a lost car key or fob?

Cost depends heavily on your vehicle's year, make, and model — a basic transponder key costs less than a proximity smart key with push-button start. Call us with your vehicle information and we'll quote you before dispatching a technician.

I have one working key left. Should I get a spare cut before I lose it?

Yes — it's much easier and often less expensive to cut a spare from a working key than to program a replacement from scratch after losing your only key. We recommend keeping at least two working keys per vehicle.

Can you make a key for my car if I've lost all of them?

In most cases, yes, depending on the vehicle's make, model, and security system. Call with your VIN and vehicle details and we'll let you know what's involved and what to expect for cost and timing.
