How your immobiliser system functions on Toyota Yaris

Before explaining the different alternatives available to you, here is a short intro to explain the aim and functions of the immobilizer in your Toyota Yaris. This electronic component appeared 30 years ago and intends to prevent the theft of your Toyota Yaris. Indeed, thanks to a transponder and an antenna (coil) included in the key, and, a immobilisation control box included in the ECU and a reception antenna on the neiman, your Toyota Yaris will go each time you place the key in the ignition, it checks that the code emitted by your key is in fact the one required by your immobilization box. It is only at this instant, that it will let you turn on your car. It is thanks to RFID technology (chip in the key) that this unit will work.

The different alternatives to bypass the immobiliser on your Toyota Yaris

Enter the code to turn off the immobiliser

First process, your key no longer enables your Toyota Yaris to start, you want to turn off the immobiliser of your Toyota Yaris, but first of all you should try this procedure to start it and take it to a garage check that you can not accomplish a less important operation to reestablish the normal start of your car. Indeed, with your car you should have a spare key (which you should try and which should start your Toyota Yaris), but if you don’t have it you should at least have the “code card”, it includes the start code. Thanks to this code, you will still be able to start your car by entering it manually. To do this, turn on the ignition, use your centralized button to enter the digits, several quick presses (example: 2 for digit 2) then a stop of one and a half seconds to validate the digit and resume, replicate the operation until you have entered the full code. This should enable you to start your Toyota Yaris without having to remove the immobiliser.
