When I first put my key in the ignition all my dash board lights go on then when I go to start the car nothing happens. All the dash lights go out and the car won't start .
I DONT HAVE A KEY WITH A RAISED CHIP , MY CAR RANDOMLY LOCKS ME OUT AND WONT LET ME START THE CAR DUE TO ANTI THEFT -----------RADIO IS LOCKED AS WELL ------ WHY
Same problem with key. Mech. thought it was the starter but even with a new one no starting at all. They tried to re-program but no positive results at all. Put it in neurtal and started once but would not start after. My Security light was on for about 8 months prior but no problem starting the car at that time. Security light turned off for about 3 weeks before this so I thought it was OK-reset.
the car would not start do to anti-theft system. I cleaned the key tried again and it started. this has happenthree times since I have owned the car.
my buick was killing on me at turns and stops but work start right back up I changed the battery and now the car wont start at all what can this be alternator starter and battery brand new
All accessories function when poser is turned on but there is no juice going to the starter. Security light is continuously flashing.
Took extra keys/items off key ring so that car key and house key are only objects on key ring. No problems since then (almost 6 months ago).
I tried to start my car, it was in perfect working condition, and it wouldn't start. I took the key out of the ignition, put it back in, made sure I had it in park and it started. Now the Security light is on all the time. After reading this page I know what to tell my mechanic to fix it!
