How your immobiliser system works on GMC Terrain

Before detailing the different alternatives available to you, here is a short intro to describe the goal and operation of the immobilizer in your GMC Terrain. This electronic component was invented 30 years ago and aims to prevent the theft of your GMC Terrain. In fact, 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 GMC Terrain will go each time you insert the key in the ignition, it checks that the code emitted by your key is indeed the one expected by your immobilization box. It is only at this moment, that it will enable you to start. It is thanks to RFID technology (chip in the key) that this unit will work.

The different alternatives to bypass the immobiliser on your GMC Terrain

Enter the code to turn off the immobiliser

First technique, your key no longer allows your GMC Terrain to start, you want to disable the immobiliser of your GMC Terrain, but first of all you should try this process to start it and take it to a garage examine that you can not perform a less significant process to reestablish the normal start of your vehicle. In fact, with your vehicle you should have a spare key (which you should try and which should start your GMC Terrain), 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 vehicle 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 process until you have entered the entire code. This should let you start your GMC Terrain without having to remove the immobiliser.

Fix your key at a key specialist or your car dealer

If in spite of a battery change, different attempts to enter the immobiliser code on your GMC Terrain still doesn’t work, it’s probably your key that’s at issue.

Manually remove your immobilizer

Although you may be tempted to bypass the immobilizer from your GMC Terrain, this is not recommended at all for different reasons. First your GMC Terrain would be much more vulnerable to theft attempts. In fact, without an immobiliser box, simply doing “the wires” may be enough to start it. In addition to that, your insurance, in case of theft most likely won’t refund you if it acknowledges that the immobiliser on your GMC Terrain has been removed, bypassed or deactivated. This if you still want to do it, some internet pages still give the methodology, we have made the choice not to disclose it, because it could help people with bad intentions.
