Question:

Toyota Techstream is a diagnostic and customization software for use with Toyota, Lexus, and Scion car models. Toyota developed Techstream for internal use and for customers who want to be a little more hands-on when dealing with their car. The Techstream Software can save you hundreds or even thousands of dollars over your vehicle’s lifetime. I bought a cheap OBD-2 to USB dongle and downloaded Techstream onto a laptop and was able to program my two 2008 Tundra key fobs. It was pretty easy. You don't need an original key. You just put the new keys into the ignition and then it programs the chips or pulls the key from the chip onto the ECU so that it knows to recognize it.

DIY Programming technique for Toyota, Lexus, and Scion smart key & remote fob.

A few years ago I bought my used 2008 Toyota Highlander Limited and it came with just one “Smart Key” to start the engine. Initially, I wanted to get a second key for a backup, but few hundred dollars price tag from the dealer made me hold off on that idea. A few months later someone commented on my Youtube channel that it is possible to program any Toyota, Scion or Lexus smart key using a special cable and software, so I started my online search. After some struggling and few failed attempts, I finally figured out the way to do it. It still cost me quite a lot of $$$, but nevertheless, I still saved about $100 compared to the dealer’s price.

Disclosures

The following smart key programming instructions are not guaranteed to work. Performing this procedure can potentially damage your vehicle, void your vehicle warranty, and cause expensive repair costs. Do it at your own risk. You can also visit our full Legal Disclosure page.

Here is what you will need:

1. 1. Windows-based PC laptop computer
   2. Diagnostic software and cable (USB to OBD2)
   3. New Toyota, Lexus or Scion Smart Key fob with unlocked smart chip transmitter
      (these are eBay affiliated links)
   4. TechStream “Professional” subscription (https://techinfo.snapon.com/TIS/Register.aspx).

Step 1

In order to program Toyota, Lexus or Scion smart key, you will need to get the diagnostic software and USB to OBD2 cable. You will need to install the software and the driver on your Windows XP, 7, 8 or 10 computer or tablet. Installation instructions are usually provided with the purchase of the cable.

Step 2

Next, you’ll need to purchase a new original OEM unlocked Smart Key fob. You can also buy a used Smart Key if you want to save money, just make sure you are buying unlocked one. Otherwise, you will have to find someone to unlock it for you, like your local Locksmith or hardware store (though very often they will refuse to do that and offer to buy their keys instead). Search for smart keys compatible with specific make, year, and model of your Toyota, Lexus or Scion.

Step 3

Install cable drivers and diagnostic software on Windows PC based computer. Installation instructions are usually included with the purchase of software and the cable.

Step 4

Programming Instructions:

• Connect your computer to OBD2 port under the dashboard of your car using the included cable
  
• Launch TechStream software and click on “Connect to Vehicle”
• Select your car make, model, year, engine
• Choose “With Smart Key” option
• *If your car doesn’t have smart key fob, choose “Without SmartKey”. Programming instructions will be different.

• Press the Start button in your car once to turn the engine/power ON

• Be aware that you will need to perform each step within the specified amount of time
• Only carry one smart key into the vehicle at a time
• Check four checkboxes and click “Next”
  
• Notice the number of available spaces for a new key. If the number of available spaces is 0, then you need to go back to “Smart Code Reset” utility firs
  
• Place already registered smart key into the car, and remove the new unregistered smart key from the car, and click “Next”
  (I rolled down the window and placed the unregistered key on the roof of my car, and it worked just fine)
  
• Press “Pre-Start Check” button and review registration process
  

New Smart Key Registration Process

• Press “Start” button to start registering process
• Within 30 seconds touch engine start switch/button with your registered smart key. You will hear one beep
  
• Within 30 seconds remove the registered key from the vehicle, place the new unregistered key into the vehicle, and touch the engine start switch/button with the unregistered smart key. You will hear one beep
