2008 Chevy Aveo security light won't stop flashing and alarm sounds when car is started. Tried everything in the manual.

SOURCE: key won't turn - key light is green

Steering is in a bind were wireless key cannot activate. Move steering wheel to the left and right while trying to start. I had the same problem and this is what the Nissan dealership told me to do. I't worked like a dream.


Hopped this helped

SOURCE: Alarm haywire, can't override anti-theft system or turn on car

The Alarm on my Mercedes ML320 sounded every night, then it started doing it more often, Showed it to the dealer he says it's the 'Tow Sensor', that needs to be repaced. $700, down the drain. I have already started hating this car, it eats $500-600, every 6 months...

I also had the same problem, But the problem lies in the switch the actual hold switch on my aveo there is a side entry way you can pop off the one on the left will give you access to the switch. what could of happen is theres is condensation in inside the switch. then when it gets cold it freezes causing the switch to malfunction. This could happen either by spilling something on the switch or using a cleaning solvent like armorall, YOU MUST BE CAREFULL WITH ANYTHING LIQUID NEAR THE HOLD SWITCH. Also the car going from warm when you drive then cold when you park it at night. My car was in warranty and remind you I came up with is the dealership had no idea what was wrong. they reseted the computer it worked for a week then was happening again. I have knoweldge in switches/wiring so i decided to check pot the switch and open it up and sure enough there was condensation took it to dealer told them to try a new switch works perfect and going on 5 months with out problems. Replacing the switch can solve pretty much every problem that is stated here i think. Also take a look at the wiring and connections for older aveos
