PLEASE READ THE DESCRIPTION BEFORE YOU BUY. 19 of these GM keys are OEM and 20 of them are aftermarket. Some of the key blades are already cut and most of them are uncut. There are a couple of brands for the aftermarket keys and some of the keys have plastic heads and some are gold and most of them are chrome. There are a quantity of x38 keys total. I’m selling them as they are all together.
