Reprogramming Key Fobs


Key Fob Reprogramming:  The fob makes up a new code each time you press it, and tells the alarm computer the new code, so that they work together.  If your fob is lost, or broken or battery goes flat, then this synchronisation will no longer occur.  You either have to reprogramme the fob (this can be done by following a simople protocol) , or if you have bought a new replacement or spare fob, or battery ahs bene flat for too long, then this has to be programmed to match with the alarm system. Unfortuantely you normally need to use a MG dealer with a Rover T4 system, which will cost at least £40 pounds, or find someone else with equipment which can perform this task (some locksmiths do apparently).

I can program the older style key fobs (squarish shape with two round buttons beside each other...one to open and one to lock - see left picture below).  This shoild include most Rovers and MGs prior to 2003/2004.  The newer keys (from 2003) are a rounder shape (right picture below), like a pie chart and have an MG badge in the middle (see below).   I cannot programme these newer ones at the moment .
