Why will these keys not work for my 1990? Right now I crank up with an ACE Hardware key (nothing wrong with it) and would love to have some AMC keys but it cuts off at '84...is it a different length/thickness/style? Or will it actually work and the seller just doesn't know any better Thanks!!

I don't see why they wouldn't work. looks like standard GM keys

[will7798]

Thats what I thought. I just wanted to see if anyone knew any reason why they may not

And for $7.50 I'd be all over that if mine wasn't the Chryco key

But they're not. The ignition cylinders are basically GM cylinders, but pre-AMC their predecessor, Hudson, used Briggs and Stratton keys, and AMC continued to use the same keyway even after the shape of the key head changed. As for cutting off at 1984, that's not correct. My 1988 Cherokee was bought new, delivered in January of 1988, and the keys are AMC keys.

So do reckon my 90 will work too? Looks pretty much the same as the key that i have now its just got the AMC on it

Dunno. There are subtle differences. If you have keys to an AMC-era XJ or MJ, compare the ignition key to the door key. Aside from the shape of the head, the actual key part is slightly different. I don't remember which way it works, but IIRC either the ignition key will go into the door locks but the door key won't go into the ignition -- or t'other way around. I'm not talking about operating the locks -- just putting the key into the cylinder. So they ARE different.
