Had a major problem with the immobiliser on my 214i bubble. Bought the car with no keyfob and found out later that the alarm had been circumvented. Anyway, needed the EKA code to reset the immobiliser, called out the RAC to help, which was a waste of time (no code, cant help) but they did give me the number for MG & Rover Codes. Went to their website and put in my chassis number, paid the fee (£15) and within 20 mins I had the code. Really helpful and honest people.
Turns out I had mistyped my chassis number and been given the wrong code but after explaining this to the owner (Mr Lewis) still gave me a ful refund. top bloke.
So use this site as its great but make sure you enter the correct details.
