I have a 96 pontiac firebird, the security light comes on and the car wont start at times sometimes up to 2-3 days. Can I bypass this.

Without a meter for testing purposes I cant help you but I would suspect that the wires to your ignition lock cylinder are broken, but without some testing I cant be sure.

You're going to need one to do this.

The most common failure in these is the sensor in the ignition lock that reads the key pellet. That would mean replacing the ignition lock with a sensor included and the Passlock Decoder Module.

That sensor can be bypassed. You would need a digital ohmmeter to measure the resistance of the pellet in the key. Now go to Radio Shack and buy a resister of the exact same value as the key pellet. Go to the base of the steering column and locate the two thin white wires that go up to the sensor. Cut the two wires and solder the resister between the two ends coming from the harness. This will permanently bypass the sensor but not the rest of the system so if the problem is elsewhere in the circuit, you'll have to get it repaired.
Here are all the available choices

I'm sure they can get one if they need to. Otherwise it's $120 per hour for someone else to do it for them.
