93 Aerostar Igniton

Sometimes my ignition key will not fit at all(like the hole is covered
up)i can take a screwdriver and wiggle it and the key will fit
but sooner or later i am afraid it won't.
Anyone know how complicated it gets to change one?

You will need a new key and tumbler set.
There shold be a little pin on the side that you can push id and pull the tumbler out and slide a new one in.
You will need the ign key in the right spot.
Try on to start with.
