What is an engine immobilizer?

March 12th, 2016 by

Here at Don Jacobs Toyota, we want you to know your vehicle inside and out so we’ll be going over some of the features available in your vehicle and how it affects your drive or ownership. As a car owner, you’ve probably come across the term “engine immobilizer”, but what exactly is that? Today we’ll go over what your vehicle’s engine immobilizer does and how it protects your vehicle.

When you insert your key into the ignition or bring your Smart Key fob into the vehicle, the key transmits an electronic code to the vehicle.

The only way that your engine will start is if the code in the key’s transponder chip or in the Smart Key fob matches the code in your vehicle’s immobilizer. That way, not just any Toyota Tundra key will work in your vehicle, despite them having the same shape configuration.

What if you lose your key or fob?

Since the code in your key or key fob is unique to your vehicle only, it can be a bit costly to replace a lost key or key fob. If you’ve lost your car key or Smart Key fob, and are absolutely sure you can’t find it, don’t worry. We can help you here at Don Jacobs Toyota. Simply contact us here at our dealership and we’ll be happy to help!

We can give you your vehicle’s key code when you present us with a form of photo identification and proof of ownership of the vehicle. We will also need your vehicle’s VIN number so be sure to have that on hand.

From there, we can use our scan tool to program your vehicle’s immobilizer system to authorize a new key to start your engine.
