Put key number on the title in a margin then you will always find it.

You can find the proper blanks on line. Like i said its a switch key blank. Someone has changed the switch which now gives you two keys for the car instead of one. To keep them apart i always ground the corners of the door key. You could have him pull the tumblers of the ignition and re key it to the door locks to go back to a single key. But its not nessary. Just make sure you mark the door key or as I have done get one of the none stock key cut for the switch key so that it is different. You risk finding your selfe twisting the switch key off in the door lock one day as they both go in.

I tested this key on another door this morning and noticed it worked but I had some difficulty as I could only unlock if I pushed inwards with some force as a turned.

After comparing them again I suddenly noticed another key difference between the OLD GM keys and the new GM blanks. While the keys themselves are the same length, the actual functional part of the key is shorter, so that may be a contributing factor. I'm going to do as John said and find some old GM blanks online and have those cut.

Your pushing the door key in to far. Original parts group , rubber the right way. Are two sources that come to mindfor the proper blank there afe a lot of differences in those two blanks.
