If you want a quick way to fix it run a wire from your starter in to the car another from the battery into the car and get a start button its quick easy i had the same problem.

Value of lost key to use a bypass module

I would get an Ignition switch with key from the junkyard and just replace it. You can get the replacement instructions out of a Haynes manual

89 firebird anti theft code won't let car start

If code 53 involves the PASS system for your car, the chip in the key has failed, or the sensor in the lock cylinder, or the control module.
The anti-theft system disables the starter and the fuel injectors. You could bypass those circuits to get the car started.

My egnition will not allow me to put key in all the way

The lock cylinder must be bad.
Unfortunatly being an 89 it should be a cylinder with the VATS key. They are a bit costly. Around $75 if I remember correctly. Then if a VATS bypass has not been done (not really a bypass of the VATS, just a bypass of the key's resistor) then you need to get a key made with the proper resistance for the new lock. The bright side is the new lock cylinders come with a key already cut so it just needs a copy or thkey with the proper resistor.

I don't know if non VATS key cylinders fit into the column properly because I have only done the repairs with the right parts.

I think has the proper lock cylinders at a desent price. If you do a web search for rock auto discount codes you can save a few bucks as well.

The security light is flashing and the car wont start how do i fix it

May have a fault in the VATS. Most likely the wires that come from the ignition lock are broke. That is the weak link of the VATS.
Need to measure the resistance of the pelet n your key and basically add that value of resistors to the wire for the lock cylinder at the bottom of the column where they come out.
If you do a search for "VATS bypass" you should find diagrams of how to do this. (This is mistakenly refered to a VATS bypass while it really is not a bypass. The Pass Key module always stays in play. It just bypasses the weak link in the system.)

I am currently diagnosing a problem with a 1992 Pontiac firebird 305 engine. Apparently numrous persons have worked on this vehicle. It has factory installed chip on the ignition key and someone has...

Some of these anti theft security distress can shut offfuel to the injectors. This might be what's happening. Check out this link for info on the security system. There is a way to bypass the entire system. Right now you have bypassed the key and ignition part, but the TDM (theft deterrent module) is still there. This is the computer that runs the security system and might be giving you problems.

I have lost my keys to my 1991 pontiac firebird my key has the chip in it for the anti thft system is the a way to bypass the security system so I can replace the lock with a standard ingition lock

there is a way I've seen it done but never have done it myself. That "chip" is like a resistor for the anti theft system. When I asked the guy how he bypasses it, he stated, "I find the correct resistance needed, then add a resistor in line so that it bypasses the ignition switch." This way the orginal keys will work even if they don't have the "chip." Now the vechile he did that on he still had the key with the chip. The chip or ignition cylinder wasn't contacting each other so it would sometimes run and sometimes wouldn't. So I don't know if he tested the key or if there is a different way. I know this isn't much help but I KNOW it can be done.

Anti theft system . Had to replace ignition key cylinder with new key that does not have a chip, can i bypass antitheft system .dealership says model firebird did not come with chip in key. need a solution...

The dealer is right...the 89 firebird did not come with a chipped key antitheft system. You should never have had a key with a chip to begin with.
