How your immobiliser system works on BMW X3

Before describing the different solutions available to you, here is a short introduction to describe the aim and operation of the immobilizer in your BMW X3. This electronic part came out 30 years ago and aims to prevent the theft of your BMW X3. Actually, 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 BMW X3 will go each time you place the key in the ignition, it controls that the code emitted by your key is in fact the one asked by your immobilization box. It is only at this moment, that it will allow you to turn on your car. It is thanks to RFID technology (chip in the key) that this unit will work.

The different solutions to bypass the immobiliser on your BMW X3

Enter the code to turn off the immobiliser

First process, your key no longer allows your BMW X3 to start, you want to turn off the immobiliser of your BMW X3, 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 significant operation to bring back the normal start of your vehicle. Actually, with your vehicle you should have a spare key (which you should try and which should start your BMW X3), but if you don’t have it you should at least have the “code card”, it contains 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, duplicate the operation until you have entered the full code. This should allow your BMW X3 to start without having to remove the immobiliser.

Repair your key at a key specialist or your dealer

If even though a battery change, several attempts to enter the immobiliser code on your BMW X3 still doesn’t work, it’s almost certainly your key that’s at issue. We can understand that you still want to bypass the immobiliser device from your BMW X3. Actually, your transponder must have been weakened or must have fallen off your key. To correct this trouble, only option, go to a key specialist (also available on the internet) or, at your dealer who can repair your BMW X3 key. Determined by 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 dealer if you have no support and you want a new functional key, it will avoid you having to remove the immobilizer from your BMW X3.

Manually remove your immobilizer

Although you may be thinking to bypass the immobilizer from your BMW X3, this is not recommended at all for several reasons. First your BMW X3 would be much more vulnerable to theft attempts. Actually, without an immobiliser box, simply doing “the wires” may be enough to start it. Moreover to that, your insurance, in case of theft most likely won’t refund you if it acknowledges that the immobiliser on your BMW X3 has been removed, bypassed or deactivated. This if you still want to do it, some sites still give the method, we have made the choice not to disclose it, because it could help people with bad intentions.
