Car Says Key Not Detected?

A weak battery in the smart key is a common cause. Many cars also have a backup spot where you hold the key so the car can still read it; your owner’s manual shows where. If the car still will not start, call us and we will diagnose it.

How It Works

1. Call us with your year, make and model.
2. We confirm the correct smart key for your car.
3. We come to you and program the key to the car.
4. We test unlock, lock and push-to-start before we leave.

Frequently Asked Questions

Is a smart key the same as a key fob?

A smart key is a type of fob that lets you start the car with a button while the key stays in your pocket. We handle both. See key fob replacement.

Can you make a smart key if I lost all of them?

In many cases yes, at your car. Call us with your vehicle details to confirm.

Does the smart key have a metal key inside?

Most do. We cut that emergency blade so it opens your door if the battery dies.
