My 91 yj has half doors and they have locks. It also matches the ignition key. The only thing that is different is the gas nozzle which has a separate fuel key.
If you are worried about the locks with the half doors, like the other guy said, just leave them unlocked if you have a soft top, someone will eventually cut through the softtop or break the lock on your door. just dont leave anything valuable in it unless you have an ammo box bolted to the floor with a lock mechanism.
