Hello i got a 2002 ls1 camaro, ani got a big problem whit it .when i try to open the car thethe security lamp goes on. i have try to lock the doors andtheni unlockthe doors and when i open the doors. the securitylamp still goes on. whats the problem ?
and i can´t start the car. It´s only klicks in the motor

 

question.

When you say the motor won't start. Do you mean when you turn the key you hear multiple clicks? This would mean low battery voltage.

If it is low battery voltage that could also affect the security system. If the battery has failed replace it then attempt to start the car and try the security lock,unlock.

 

no i only hear one click and i have upload the battery tofull.I have also test whit another battery. i don´t have a security lock/unlock

 

One solid click my first guess would be a issue with the starter itself. Make sure your connections to it are good and clean and also make sure the s- wire that feeds from the starter switch is connected (small terminal on starter). Then see if your getting signal from the ignition switch at the starter. If not, could be a ignition switch issue or a BCM issue causing the no-crank.
