95 Camaro wont start security flashing

I recently bought a 95 camaro 3.4v6 and was doing some exhaust repair which required me to disconnect the battery. when I finished and cnnected the battery and the security sytem went off and the car will not start.

How can I bypass or diable the security system????

You will probably have to bring it in. It's a security feature wen you take the battery out. It will reset everything...if you have key less remotes the would also not work and the radio would also not work if you had theft codes set for it...but I don't know about the security system. I'm guessing you just have to reprogram it somehow.

Is the security light on the dash lit or blinking when you try to start the car?
