650xv wont disarm

Hey guys a friend of mine has a 650xv and i went to disconnect the battery to put the 12v wire for his amps in and when i put the connection back the alarm started going off..   so i disarm it from the keyfob but it does nothing so i dug around for the brain and pulled the main harness out..   whenever it gets plugged back in the alarm goes off.. i figured by unplugging it i might have lost the programming to the remotes so i tried putting the car into valet mode after i set off the alarm by puting the key to run and pressing the valet swtich once..   nothing alarm keeps going off..   how long does the car take to respond after you put it into valet mode so i can check everything? i dont have a bitwriter so i cant even get in it that way. -MikeDriving a Bagged, Caddied 02 s10

you cant get into valet mode with a Bitwriter anyway.... sometimes you have to press and hold the valet switch more than once to shut off the alarm.....Kevin Gerry

even if the unit has been unplugged for over a year about? i figured it woulda dropped the programming by now.. when putting it into valet mode.. do i have to just press it in and release or press and hold.. that type of thing...Driving a Bagged, Caddied 02 s10

ive traced all the wiring and havent seen a ghost switch its just the standard valet plugged right into the brain.. so.. i tried it justby key on and press it.. didnt know i had to key off also... Driving a Bagged, Caddied 02 s10
