I just changed the Ign. lock cyl. on a 94 Mustang. I noticed the replacement cyl keys only have cuts at the tip, about 4 or 5 cuts. Is there a way to make this car a 1 key car again? Does the ign. only use the frt. half of the key and the doors and trunk the back half?
Ignition uses spaces 1 through 6 Doors & Trunk use spaces 5 through 10 Spaces 5 & 6 are common cuts. If the cuts in spaces 5 & 6 are the same on your original key and the replacement keys-You are in luck.
If not, you can take the ignition cylinder to a locksmith and have it rekeyed.
If this ever happens again,(Fords that use 10-cut keys) go to a locksmith and show him/her your original key. They can measure the cuts and sell you a cylinder that will operate on the common cuts, keeping your car a one-key car.
Hope this helps. goma.
Doors contain positions 1-6 and ignition is 5-10.

The other replies you have are sort of correct in that they describe the way the factory has it's original locks. On the replacement locks they have only 5 cuts in them rather than 6. This means that you are supposed to select one of 5 options that match that same cut as your original key, then you just have the locksmith cut the 5 other door cuts on the new ignition key and you are back to one key.
So it seems that you have a 1 in 5 chance that you got a compatible ignition to return to one key for your car. Take it to your local locksmith to see if you got lucky.
FWIW... 2 things need mentioning..
the local FLAPS (auto supply places) AFAIK, ONLY have the lock with a 1 cut in the 6th place..never got anything else BUT that.. (ANOTHER FUNNY, as I repin a LOT of these, is they have the wafer in the 5th place, which is WRONG.. but the lock seems to work anyway..)
and you must either go to a locksmith, OR if you got a GOOD parts person at the dealer, that knows whats up, can order a lock pinned with the proper 6th cut already there, so you just have to have your 7-10 cuts and the 5th cut, copied to your lock.. dealer locks are REAL expensive tho.. USUALLY THO, its better getting a totally unpinned lock and cut new keys by code and pin as needed.. I have NEVER seen a 10 cut key from the 90's era that was not worn pretty bad..unless this was just recently done, but as far as a day to day used key, they wear.. last point is these are a tip stop, and the tip does wear out.. makes the ignition difficult to turn, adding to the usual problems with the 10 cuts.
