Someone tried breaking into my truck again (3rd time) a few months ago. I finally got around to ordering another lock cylinder. The instructions say the key code for the tumblers may have come with the vehicle. Does anybody know where it would be?

I don't have that credit card thing with a key punch out. Thanks, Mike

 

there on the fire wall. behind your rear seats, in a little black box on the right top corner.

 

Tonka aren't you referring to the door code?
