Before Trying to Bypass the immobiliser, Do you know what is wrong with it.??

i,e if the problem is the key, Transponder ariel or UCH then you might be able to get the ecu made free running, But if the problem is a faulty ecu or faulty wiring / relays to the ecu then bypassing the immobiliser wouldn't be of much use.

And Yes, The Customer always thinks its a good Idea to just take the immobiliser off as they think that its the cheapest option and it cured their mk 3 Escort that way.

We would spend 1-2 hours checking it over and most likely repair the car rather than trying to bypass anything.

The only thing that would cause us any major problem would be a faulty ecu, The other stuff would be relatively easy to replace. ( keys, UCH, Transponder ariel, wiring , relays etc.

These cars used to be a headache for us but they are usually fairly straight forward to repair now. ( Except the ones with throttle body problems )

P.S Whats happening to the immo LED with the ignition on, is it Stopping on, going out or flashing rapidly.
