How your immobiliser system works on Toyota Highlander
Before detailing the different solutions available to you, here is a short intro to demonstrate the goal and functions of the immobilizer in your Toyota Highlander. This electronic part appeared 30 years ago and intends to prevent the theft of your Toyota Highlander. Indeed, thanks to a transponder and an antenna (coil) integrated in the key, and, a immobilisation control box integrated in the ECU and a reception antenna on the neiman, your Toyota Highlander will go each time you put 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 moment, that it will permit you to start. It is thanks to RFID technology (chip in the key) that this device will work.
The different alternatives to bypass the immobiliser on your Toyota Highlander
Enter the code to turn off the immobiliser
First methodology, your key no longer enables your Toyota Highlander to start, you want to deactivate the immobiliser of your Toyota Highlander, but first of all you should try this technique to start it and take it to a garage verify that you can not accomplish a less important operation to restore 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 Highlander), 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, repeat the operation until you have entered the entire code. This should let you start your Toyota Highlander without having to remove the immobiliser.
Fix your key at a key specialist or your car dealer
If even though a battery change, different attempts to enter the immobiliser code on your Toyota Highlander still doesn’t want to start, it’s most likely your key that’s at issue. We can understand that you still want to bypass the immobiliser system from your Toyota Highlander. Indeed, your transponder must have been affected or must have fallen off your key. To fix this issue, only solution, go to a key specialist (also available on the internet) or, at your car dealer who can fix your Toyota Highlander key. Based on who you go to the repair should cost you about 100 euros if you still have a duplicate or your “code card” and about 350 euros at your car dealer if you have no support and you want a new functional key, it will avoid you having to remove the immobilizer from your Toyota Highlander.
Manually remove your immobilizer
Although you may be attracted to bypass the immobilizer from your Toyota Highlander, this is not recommended at all for some reasons. First your Toyota Highlander would be much more vulnerable to theft attempts. Indeed, without an immobiliser box, simply doing “the wires” may be enough to start it. Additionally to that, your insurance, in case of theft most likely won’t refund you if it acknowledges that the immobiliser on your Toyota Highlander has been removed, bypassed or deactivated. This if you still want to do it, some internet pages still give the method, we have made the choice not to disclose it, because it could benefit people with bad intentions.
