Early MGB Keys
Author: A. Henderson
The earliest of the MGBs used keys supplied by Wilmot Breeden in the "FP" series as per the MGA. The keys were either round headed, or rectangular in body shape. Ignition locks using the "FP" series of keys had the key number stamped on the face of the ignition lock cylinder, and on the latching part of the trunk lock cylinder, and on the barrel of the door lock cylinders. Key #s were also clearly stamped on one face of the key.
Later MGBs used the Wilmot Breeden "FS" series of key. It is possible that some cars may have received sets of "FS" series keys prior to totally exhausting the supply of "FP" series keys. The latest car which I know received "FP" series keys had a car number of 11,100 approx. Later MGBs were supplied with "FS" series keys to the end of production in 1980. "FS" series keys could be round headed, pentagon headed, or oblong.
Although it is possible to key all of the Mk 1 MGB locks to operate with a single key, all were supplied with 2 different keys of different code, probably so that an ignition key could be left at a parking or service facility while enabling the driver to lock his trunk and glovebox.
FP lock cylinders are extremely difficult to source, as the trunk and door lock cylinders are unique to the very early MGB.
There are few sources for original "FP" keys.
Early MGB Key Fobs

The Mk 1 MGB was delivered with leather samples to match the primary interior colour attached to two of the factory supplied keys, 1 each of the ignition and door keys. These samples were either black, blue or red.
The originals have a silver stamped "MG" octagon on one side and "Real English Leather is Used in this Upholstery" on the other side.
Some replacement ones I happened across are accurate as to leather colour but use a gold stamping for the printing.
It is unknown as to when the practice of shipping original keys with leather fobs installed was discontinued, but before the start of Mk 2 MGB production. It is believed that these fobs were also shipped with the MGA.
