How your immobiliser system works on Seat Ateca

Before describing the different solutions available to you, here is a short intro to show you the purpose and functions of the immobilizer in your Seat Ateca. This electronic part came out 30 years ago and intends to prevent the theft of your Seat Ateca. 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 Seat Ateca will go each time you put the key in the ignition, it controls 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 let you turn on your car. It is thanks to RFID technology (chip in the key) that this system will work.

The different solutions to bypass the immobiliser on your Seat Ateca

Enter the code to turn off the immobiliser

First methodology, your key no longer permits your Seat Ateca to start, you want to deactivate the immobiliser of your Seat Ateca, but first of all you should try this procedure to start it and take it to a mechanic verify that you can not execute a less important process to reestablish the normal start of your vehicle. Indeed, with your vehicle you should have a spare key (which you should try and which should start your Seat Ateca), 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 confirm the digit and resume, repeat the process until you have entered the entire code. This should allow your Seat Ateca to start without having to remove the immobiliser.

Repair your key at a key specialist or your car dealership

If even though a battery change, different attempts to enter the immobiliser code on your Seat Ateca still doesn’t work, it’s likely your key that’s at issue. We can understand that you still want to bypass the immobiliser system from your Seat Ateca. Indeed, your transponder must have been weakened or must have fallen off your key. To correct this problem, only option, go to a key specialist (also available on the internet) or, at your car dealer who can fix your Seat Ateca key. Depending on who you go to the repair should cost you about 100 euros if you still have a copy 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 Seat Ateca.

Manually remove your immobilizer

Although you may be tempted to bypass the immobilizer from your Seat Ateca, this is not advised at all for some reasons. First your Seat Ateca would be much more vulnerable to theft attempts. Indeed, without an immobiliser box, simply doing “the wires” may be enough to turn your car on. Moreover to that, your insurance, in case of theft most likely won’t refund you if it realizes that the immobiliser on your Seat Ateca has been removed, bypassed or deactivated. This if you still want to do it, some websites online still give the methodology, we have made the choice not to disclose it, because it could benefit people with bad intentions.
