Most vehicles built since the late 1990s use a transponder key — a key or fob with a small chip that talks to the car’s immobilizer. If the car doesn’t recognize the chip, the engine won’t start, even if the key turns perfectly in the ignition. That’s why a key cut at the hardware store may open the door but won’t get you down the road.
Programming done at your location
Hayman’s Locksmithing carries programming equipment in the van. We connect to your vehicle, add the new key or fob, and test it with you before we leave. No tow, no waiting room — just a working key in your hand.
Common reasons to call
- You bought a key or fob online and it needs to be set up
- A spare key that used to work no longer starts the car
- You lost a key and want it removed from the vehicle’s memory
- Your car shows a security light or “key not detected” message
- You need an additional key for a new driver in the family
A note on online keys
Keys bought online can save money, but not every blank is compatible with every vehicle, and some arrive already locked to another car. Call us with the part number before you buy and we’ll tell you whether it’s likely to work.
Frequently asked questions
What does programming cost?
It varies by vehicle and key type. Call for a free quote — we’re happy to talk it through before you commit to anything.
Can you program a key I bought myself?
Often, yes, as long as it’s the correct key for your vehicle and hasn’t been locked to another car. Call with the details and we’ll let you know.
Can you erase a lost key from my car?
For many vehicles we can remove lost keys from the car’s memory so they can no longer start it.
