My 2006 cobalt wont start

A nice simple answer, you can't. Think of it this way, the car doesn't know you are the owner, and it is there to stop exactly what you are trying to do. You have two computer ECM and BCM, plus the antitheft module and a number of sensors all trying to stop you. All you have to do is the re-learn procedure. Plan B is an auto electrician or alarm / radio installer or auto locksmith.

30 Minute Re-Learn Procedure

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
4. Turn OFF the ignition, and wait 5 seconds .

Dead cell and or loose grounds at the starter will do it every time!!

Have mechanic check it out,,could be so many things....fuel system,,motor not firering,, sensor failed and on and on.....

could possibly be the shift lock or the key switch might need replaced but in order to do this you need someone qualified because this process is nt easy.i have repaired alot of these at the chevy dealership i work at.

Have you tried shifting the gears completely through and then putting the car in park. It sounds like the car isn't able to be put completely in park to release the key. Try putting the car in N and removing the key. Even thought the car may not completely be in park to release the key, The gear most likely is in park but not enough to make the switch/sensor to release.

My cobalt turns over but doesnt start up and i dont know whats wrong with it to get it fixed.

you migh have to put foot on brake to start car

you will need to do a security relearn.
1.turn key to on position and leave on
2.after 10 minutes the light will flash and go out turn the key on to off 3x then leave on again.
3. do this 3 times for 30 minutes then after 30 minutes your 3rd time and after turning the key 3 times the 4th time start the car. it should start right up.

Try this Put your key in turn it on dont start wait 10 mins remove key wait 10 seconds repeat this a total of 3 times. Your theft light should go out. As long as the light is on your fuel system is disabled. If that dont work try a different key do the same thing. If that dont work a dealer needs to probably replace and reprogram your ignition switch and keys

Are you using the original key that came with the car? The chip in that key may have gone bad. Try using the spare key that should have come with the purchase of the car. You may also be having battery issues. If all else fails....call the people who really know how to rape you...DUM Dum dummmmm....the dealer
