how do I by pass alarm/security system in 1998 lesabre wont start due to system
if it is a factory alarm, find the fuse for it and remove that fuse. If it is an aftermarket alarm, find the red wire at your battery that powers it up, and disconnect this wire.
is this the factory theft system ?, if it is yiour ignition lock cylinder went bad, will need to replace lock cylinder, or you can omn out ignition key chip thats on key and buy a resistor at your local radio shack, connector resistor at connector at bottom of steering column and solder in at connector, this will let security system have correct resistins and by-pass ignition switch
