Thanks to all early posters on putting a switch inline on the yellow passlock cylinder wire. After suffereing stranding for the last time, I acted on my 2002 Malibu. My biggest problem was getting the stupid passlock to work one last time so I could flip the switch to off that I installed while waiting the multiple 10 minutes between tries. I now have the comforting solid-on security warning light as advertised, and am hapilly driving with confidence in starting first try.
