i never knew that my car had an immobiliser,because my genuine key has a battery inside and it works like a lamp when u want to insert the key to the door lock at night.so how can i take off the immobiliser on my fabia.eventaught it has an alarm system that only works when you insert the key in the ignition. can i have some help on this please?

sorry mate immobiliser is non-removable belive me i have looked into this and felicia,octvia,fabia, and superb's immobilisers are 100% tamperproof.

what have you done to disconnect immobiliser?

I think the answer to your question lies here

vegetu, you may be able to start the car each time you want to drive it by using a 4 digit code which is given to owners when they buy the car. But that will only work if the immobiliser is not damaged in some way.
