You do know there are only about 7 key patterns. I have used my 1984 Shelby key in my 87 Omni and in my 91 Daytona. My two Rampages also share the same key.
It may just take a slight giggle while pulling the key back and fourth a bit but I have jimmied a lot of Mopars over the years, Chevy's too.

When I worked for the phone company we had all Chevy vans. When we had a tech lock himself out of his work van, I'd grab all the spares in the office and go out and jiggle the door lock and usely it was the 3rd key would open the door and unlock the steering. Would not start due to chip but I could unlock so a tow truck could move it as needed.
