Fragus

It has the Lucas Immobiliser, with the round black fobs, the car is a 2002

Hi All
My MGTF is in the garage at the moment, being repaired. However, every time they try to turn the car over, it turns over twice, and the immobiliser light kicks in on the dashboard and shuts it down. Once the keypad button is pressed it can then be restarted, but repeats the same process. I have the original type keys with the black fob.I am not sure what the options are for me. Can this be bypassed/disabled, if so does anyone know what the steps required are, so I can then inform my mechanic/technician, or if anyone knows anyone in the Milton Keynes area that can do this. Are there any other options available?
