Resetting the ECU

Hi everyone, I have heard the ECU can be reset by disconnecting the battery and leaving for ten mins or so. The only problem is I don't have the master key for the immobiliser. Is it likely the car will need this key to get it started again afterwards? When I replaced the battery I only had it disconnected for 5 mins tops IIRC.
Many thanks
