Triumph BSA Norton Wilmot Breeden-Type FS Key Blank PN# 62FS TBS-0027

Known as the Wilmot Breeden FS key, this is the most common key used in the original Lucas 54335169 ignition barrel, as fitted to British motorcycles and automobiles in the 1960s and 1970s. This key is only compatible with original Lucas ignition barrels and will not fit in reproduction tumblers. Not suitable for use in the earlier 88SA ignition switches.

This key blank has the correct “Polybow” head shape, with the WBH logo. The channels are cut for use with the factory original Lucas 54335169 ignition lock. Made in the UK.

The key blank must be cut to match the profile of an original FS key, so that the pattern will engage the plates in the tumbler correctly.

An original FS key is used by a locksmith to duplicate the pattern for operation in the ignition barrel.
