How To Reprogram an ECU - Immobilizer In A Toyota or Lexus

If I helped ya out and you would like to buy me a drink ➢ ko-fi.com/gera...
In this video I show a simple way of resetting / reflashing an ECU in a Toyota or Lexus. This resets the immobilizer, but this tip is not used to reprogram NEW keys.
The known vehicles listed below should have a Transponder ECU that have learned (stored) the keys. All you need to do is the join between the ECU and the Transponder Key ECU for this to work.
If you have changed the Ecu computer this can be used to re sync up your keys without the need for a trip to the dealer or investing in an expensive scan tool. You won't need to relearn the keys to the ECU separately in these models.
