95 Audi 90 anti theft reset?
 

Need help resetting my 95 Audi 90 anti theft alarm system. Took the inside driverside door panel off in hopes of repairing the door lock push/pull mechanism which initiated the anti theft horn and emergency flashers. Car won't turn over also. Any advise would be appreciated. I did pull the positive battery cable briefly, maybe 15 seconds, and replaced hoping to reset, but it didn't work. Thanks in advance.
