1996 Buick LaSabre; I recently replaced my driver-side door handle to include accessories inside door panel with "used parts from junkyard." Power-door lock works but security alarm (blaring horn) went off continuously until wire for horn was disconnected...my problem is as soon as the wire was disconnected, the entire car went into lock down...nothing works, can't start car! Trouble-shoot how?

It sounds like you may have replace the door parts on your 1996 Buick LeSabre with parts from a car that did not have a theft system. Please double check your work and make sure the parts you replaced are the same as the old ones and all the electrical connections that were connected before are connected now.
