Quick answer:
- Programming registers a key’s chip code with your car’s immobilizer.
- It takes diagnostic equipment plugged into the car — we bring it to you.
- Your VIN and proof of ownership are part of doing it correctly and securely.
Cutting vs. Programming
Modern car keys involve two separate steps. Cutting shapes the metal blade (or generates the code that does) so it physically fits the door and ignition. Programming is the electronic step: it tells the car’s computer that this key’s transponder chip is authorized to start the engine. A key that’s cut but not programmed will turn the lock but won’t start the car — and vice versa.
The Step-by-Step Process
- Identify the vehicle. Year, make, model, and VIN tell us the key type and security system.
- Cut the blade. Either by code or by duplicating an existing key.
- Connect to the car. Our programmer plugs into the diagnostic (OBD) port.
- Register the chip. The new key’s code is added to the immobilizer’s memory.
- Test. We confirm the key starts the car and operates the remote.
Why Proof of Ownership Matters
Because programming can authorize a key to start a vehicle, a reputable locksmith verifies you own (or are authorized for) the car — usually with ID and registration. It might feel like a formality, but it’s exactly what protects you and your vehicle from someone having a key made without your knowledge. It’s also a sign you’ve hired a legitimate pro — see how to choose a locksmith.
How Long It Takes & What It Costs
For many vehicles, the whole job is done in under an hour at your location. Some models with tighter security take longer. Cost depends on the key type — a basic transponder is far cheaper than a push-to-start proximity fob. We give an exact quote once we have your vehicle details; see the ranges in our pricing guide.

Frequently Asked Questions
Do you need to plug into my car to program a key?
Yes, for nearly all modern vehicles. Our programmer connects to the diagnostic (OBD) port to register the key with the immobilizer. We bring the equipment to you.
Can you program a key if I’ve lost all of them?
Yes, for most vehicles. An all-keys-lost job takes a few extra steps but is routine — see our guide on losing your only car key.
Why can’t a hardware store do this?
Hardware stores can cut a blade but generally can’t program the chip to your car’s computer, which requires automotive diagnostic equipment and vehicle-specific procedures.
