Mystery Ignition Locks

I would like to know if anyone can help me find out what two different ignition locks go to. We were going through some old stock and found these two ignitions and I cannot get the numbers to cross over to anything that we can access.

They both take a “Mazda/Ford” type key - X244. These are the ignition types that had “part” of the cuts already and then you put the rest of the cuts on the key so that the vehicle worked with the ONE key as was the original setup.

One package actually has an ALL LOCK part # of 141303 and it comes with a tag that has 134A on it. If we could come up with what year or years of vehicle it would cover would be very helpful. The other lock is a Hurd lock with a 200B000. That tag also has a date on it of 02/07/85. Hope you can help.

These are locks for Ford 10-cut, not the X244 key. The All Lock cylinder fits Aerostar 86-92, Explorer 91-92, Continental 86-87, Mark Vii 85-89, Town Car 86-89, Cougar 84-92, Topaz 88-92. The ----03  shows the depth of cut in the fifth position (“3”). The ignition lock has no tumbler in the 6th position. A locksmith could stock 5 different ignition locks with endings 01-05.  10-cut  ignition locks have tumblers in positions 5-10.  Door locks have tumblers in positions 1-6. A locksmith could replace the ignition lock using the same cut as the 5th cut in the door lock. The locksmith could then cut the first 6 cuts to fit the old door lock, then door and ignition locks would be keyed alike without working on the door locks.  I am sure you will find that the keys for your locks have no cuts in positions 1-5, The All lock ignition key will have a “3” cut in the 6th position (reading from the bow).

I cCan’t help you with what the Hurd lock fits but it probably fits Ford vehicles from the same era.  Now all you have to do is find a 25 year old car that has a “3” in the 6th space and needs a new ignition lock.
