Immobiliser problem

[PaulTVR]

Hi
I have an MGTF which dies on me on the way home recently. I thought the problem was a flat battery caused by a faulty alternator. After fitting a new alternator and charging the battery the car started and ran well for a day. I checked the voltage across the battery when the engine was running and got a healthy 14.5 volts.
Today the car will unlock using the key fob, or inserting key in door, but the immobiliser will not turn off. I have tried using the EKA but no luck and I have disconnected the battery and left it for a couple of hours but still no luck.
Any suggestions please?

We had this problem with a car we had many years ago, turned out it was the boot lock which was faulty and causing the alarm to go off.
