A Toyota Master Diagnostic Technician shares All you need to know about Toyota keys for mechanical and Smart keys. Everything from basic operation theory, programming and diagnosis.

In this video I share information on Toyota keys. I start off with mechanical keys. I explain the difference between chip keys and non chip keys and how they related to the immobilizer. Also I show you how the key chip looks like and where it's located in the body of the key. Then I talk about the difference between valet keys and master keys.

Then we go into the Smart key system with a very brief explanation of what it does on the consumer side then we dive into how the system actually operates with the multiple layers of security to prevent theft.

We'll also talk about programming with detailed information straight from my experience doing this every day through my career at a Toyota dealership. We'll cover what types of programming there is. Also we'll cover what happens if you loose all your Toyota keys.

We'll touch briefly on some diagnosis tips including the no start issue following a dead battery on smart key Toyotas.

Lastly I said this in the video and I will say it here. Please have a 2nd key at all times. If you loose one of the keys make another copy so you never have to be faced with loosing all keys and having to tow the car.

If you use a locksmith make sure they are experienced and know what they are doing especially when you loose all keys because inexperienced ones can brick the car and make the repair much more expensive.
