According to this drawing, there is an ‘inhibitor switch’ in the ignition switch on the Cutlass Supreme: [http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c15280068209](http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c15280068209) From these wiring diagrams, FIGs 15, 16, 17, choose your engine size: [http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c152800680c1](http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c152800680c1) and determine if your car has anti-theft. ---

IT is possible if someone put a resister in-line, and cut the wires that go up to the lock ( bypassing the loop that the resister in key generally closes ). This is often done when after market alarms are installed, or someone is too frugal to replace a malfunctioning lock cylinder. We charge 25.00 for these type keys It is not “fake” Jeff City Lock 2898 30th St Boulder CO 80301 > **[Your Local Boulder locksmith service City Lock](http://citylockusa.com/)** > > We have been a Boulder Locksmith for over 35 years, Transponder keys, Lost keys.
