Car Key Programming Explained — What Most Drivers Don't Know

Modern cars use transponder chips and smart keys to prevent theft — but that also means programming is critical.

Here's what you should know:

- Each car's key has a unique code stored in the vehicle's computer.

- Without proper programming, a new key won't start the engine.

- Many cars (Ford, Toyota, GM, Honda, Hyundai) require specialized diagnostic tools — not available in stores.
