British Car Keys

FA Wilmot breeden key display.
Period shop display of wilmot breeden UNION keys

Wilmot Breeden (UNION) keys were used on early Austin Healey, Jaguar, MG's, Morris, Triumph cars and British motorcycles.  The  key code number was stamped on the face of the ignition switch. Example; FP 735. On later cars, no key code is stamped on the face of the lock insert. Owner may find a piece of paper with the key code number in the housing of the ignition switch. The original car owner's for later cars  also received a metal tag with the key code number.  Used Audi cars for sale throughout the UK from Netcars. 


The owner is not a locksmith by trade. My web page is to advise restoration shop and car owners of what  is available.. I do re-key lock for the ignition switch, glove box lock and door locks. My web page has a key interchange link, information about re-keying locks. I have a good selection of used ignition switch lock inserts. Lock inserts were coded with both letters and number on face of the switch. Example: MRN 50, FNR 25, FA 501, FP 626 and FS 876. 

The door locks, glove box lock, trunk lock will have numbers stamped on the body of the lock (No letters). For example, on my TR 4 the trunk handle steel rod will have ###.  You will have to remove the handle to view the three digits number.  For the glove box lock, the number is stamped on the lock. For cars after 1967, no key code number is stamped on the glove box housing. I do have a ring of pre-cut keys (FNR, FA, FP, FS  & FT)  that I can  send to car owner.  You will have to insert each key into the lock, determine the correct key code number.  You will also receive a un-cut key American key blank to have a key duplicated in your area.

The key code number may be listed on the British car build record. You can request it from British Motor Heritage web page. For Jaguar owners see web page to request car information.  I would requests the key code number with the inquiry.
