Disabling PATS system
 

I have a 00 galant with only 1 key, yes its chipped & its pretty worn out. Is there a way to bypass the anti theft so I dont have to drop a few hundred bucks for a dealer to reprogrsm the system to a new ignition switch? When I had my ford, it had the PATS too & the dealer quoted me around $150 just for a programmed key
