Can anyone tell me the steps to reset this dealer installed alarm? It has a valet switch. Installed in 2001 in Texas Chevrolet Dealer. Cannot find anyone who can work on it here in Florida.

If there is a valet switch then it is a aftermarket alarm installed by the dealer. The factory system has your gm key-less entry fob they do not put valet switches on the factory system that was built at the plant where it was built. There are no stereo alarm shops around you?
