Powertrain Reprogramming
Beginning with some 2001 models and expanding to all models by 2007, Toyota/Scion/Lexus vehicles have flash reprogrammable powertrain ECMs.
Reprogramming is only performed if a Technical Service Bulletin or Service Campaign provides direction to do so. Flash reprogramming can be accomplished using a scantool or a PC and a 'Toyota validated' J2534-1 interface.

Scantool Reprogramming
Toyota/Scion/Lexus ECMs can be reprogrammed using either TIS techstream, Techstream Lite, previous Toyota/Lexus factory Diagnostic Tester, or the Vetronix Mastertech scantool. The ECM reprogramming function is only available with the authentic Toyota factory scantool software which runs on any of the above mentioned scantools. Please reference the following link for more information: TIS Techstream
The Toyota Diagnostic Tester scantool can be used for all flash reprogrammable Toyota/Scion/Lexus ECMs, 2001 through April 2007. The Diagnostic Tester Scantool is not recommended for service reprogramming operations introduced after April 2007.

You are here: › › › Toyota and Lexus Reflashing Services Toyota and Lexus Reflashing ServicesEarly Toyota and Lexus vehicles operated a bit different from the later systems do. There are lots of differences but the main one you will actually care about is that if you lose your last key to one of these vehicles the cost for new keys seems really high.
It’s because Toyota and Lexus (same company) in their infinite wisdom thought it would be a good idea to not give anyone access to the ECU (the part in the car that stores the chip key data) through the standard diagnostic port. That means you can’t plug-in a diagnostic machine and simply add in keys like we can on the later models.This leaves you with 3 options. Sell the car (Yeah right!).
Tow it to a dealer and pay to have the ECU replaced, synched to the car, and then to program in the brand new keys they sell. Make sure you are sitting down when you hear the price of that!. Call us. We can re-flash your current ECU and add in two keys for a fraction of the cost of a brand new part, labor to install and high programming fees.Reflashing means that we write over the current files in the ECU and convert it back to its virgin unused state. After it’s been overwritten, we can add in new keys! Here is the list of vehicles that need to be reflashed if all keys are lost.
