xro9100 program mode lockout

Finished installing an xro9100 into a 1999 Ford F-350 diesel with remote start. Everything went as expected and the system is working fine, with two exceptions, the timing setting for the wait to start timer and crank time. I want to change them a bit (crank longer and shorten the wait to start). When I try to go back into the program mode, the control unit will not let me back in. The valet switch is working, when I hold it in for three seconds it pages the remote. When I turn the ignition on and press the valet button three times, nothing...

Any thoughts?

My deepest and most humble appologies guys (and gals).. After checking my connections, I noticed that the ignition #1 wire had broken contact.... Everything is just fine!! Can't remove post as I am a rookie, an  rookie at that!!

I know, check connections, check connections, check connections....
