How your immobiliser system works on Ford Focus
Before detailing the different alternatives available to you, here is a short intro to explain the purpose and operation of the immobilizer in your Ford Focus. This electronic component appeared 30 years ago and aspires to prevent the theft of your Ford Focus. 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 Ford Focus 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 expected by your immobilization box. It is only at this moment, that it will allow 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 Ford Focus
Enter the code to turn off the immobiliser
First methodology, your key no longer enables your Ford Focus to start, you want to deactivate the immobiliser of your Ford Focus, but first of all you should try this technique to start it and take it to a mechanic verify that you can not execute a less significant operation to restore the normal start of your automobile. Actually, with your automobile you should have a spare key (which you should try and which should start your Ford Focus), 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 automobile 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, replicate the operation until you have entered the whole code. This should allow your Ford Focus to start without having to remove the immobiliser.
Fix your key at a key specialist or your car dealer
If in spite of a battery swap, several tries to enter the immobiliser code on your Ford Focus still doesn’t want to start, it’s likely your key that’s at issue. We can understand that you still want to bypass the immobiliser device from your Ford Focus. Actually, 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 restore your Ford Focus 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 Ford Focus.
Manually remove your immobilizer
Although you may be tempted to bypass the immobilizer from your Ford Focus, this is not recommended at all for many reasons. First your Ford Focus would be much more vulnerable to theft attempts. Actually, without an immobiliser box, simply doing “the wires” may be enough to start it. Furthermore to that, your insurance, in case of theft most likely won’t refund you if it acknowledges that the immobiliser on your Ford Focus has been removed, bypassed or deactivated. This if you still want to do it, some sites still give the methodology, we have made the choice not to disclose it, because it could benefit people with bad intentions.
