Yes, and no. The pattern is the same on both
sides, so physically it will work, just like a Ford.
However, some cars have an electronic "key" inside
the metal key. There's a sensor in the lock that
detects the correct key. Without that, the correct key
pattern won't operate the ignition.
Buying an extra blank key with the correct chip is
a little expensive. But you could do it if one car had
the chip and the other didn't.

In reality, it depends on the lock cylinder. I haven't taken one apart but
if it has tumblers on both sides, then the two sides must match for the key
to turn. I don't know if they did it that way but it is something to think
about or at least ask about.

I did it on my 92 and 90 Dodge pickups. Not a big deal and it works
perfectly. I used a blank with plastic on the end and I filed a notch on one
side so it was easy to determine what side was for what truck. Makes a great
spare key to keep in your wallet too.

Yes, that will work. Just make sure that the keys aren't SKIM keys which
have an electronic transponder built into them. They will still unlock the
doors, but will not start the vehicle.

Got a little story to add that kinda relates. I had a 93 New Yorker that the
ex wife drove, and a 97 Ram 1500 4x4. The keys where interchangable, each
worked in the other.

Sure, there is a finite amount of key tooth configurations before they
repeat, probably around a hundred or so; a locksmith would know the actual
number.

similar thing happened to a friend of mine...had a dodge caravan and wasn't
sure where he parked...saw one identical to his and unlocked the door with
his key but the ignition wouldn't work with it.
