GearheadGrrrl Posted December 28, 2012 Share Posted December 28, 2012 Judging by the user name I'd guess you're a USPS employee working on a USPS Mack tractor. If they're still doing thingsthe way they were when I worked for USPS, Mack provided a custom manual for the USPS Macks and the info should be in there. I retired from USPS MVS just before they got the 2006 Macks, was a TTO for a dozen years. If you have no luck there or here, I suspect the keys are programmed a lot like car keys.
