When I try to start car, security system will not allow the car to turn over. If I get out re-lock the doors, open the door with key and try to re-start it works sometimes. Other times I have to jiggle the gear shift, other times I have to disconnect the battery cable and re-connect. Now none of this is working. The security system is factory installed by previous owner. An automatic car starter was also previously installed and then removed. I bought this car used with 200,000 miles.

Re: factory security system won't allow car to start
Do you have a remote? sometimes when you have remote unlocks and lock with the remote and try to unlock manually(with key) the security system "thinks" its being picked and will not allow the vehicle to start or run.

Have you tried resetting the alarm by locking and unlocking the drivers side door?If you do this a couple of times in some cars it will restet the factory security system and allow the key to work again. Some ignition keys have a resistor built into them and the cars computer is programmed to that resistance. The security system needs to verify the resistance for the key before it will let the car start. What I have read recently about this subject basically states that if you are having problems with a car not starting, won't turn over, no clicking but the car still has power....and everything seems fine in the car....battery, starter, alternator, etc. but the security light comes on in the car and the car eventually does start usually 5 minutes or so later then it is the cars security system that is causing the problem. It doesn't recognize the resistance of the key. It sounds like the security system needs to be replaced or bypassed. A friend of mine has a '94 olds royale 88 that started having this problem a few months ago. The car isn't fixed yet but that is just because I just found this information on the security systems on the internet a few days ago. It looks like it is a somewhat common problem with some of the cars that GM made when they first started installing the Passkey I, II and III systems into their vehicles. I hope this helps and if someone else has more information on this subject I would be interested in hearing about it. And you should check the ignition key switch on the steering colum it will have one of the two wires broken.This sets off the security system which kills the ignition and the fuel pump system.When replacing the key switch make sure you buy one from the dealer most aftermarket switchs are poor quality and if go through the trouble of taking the steering wheel off and parts of the colum do the job right the first time.After you put the new key switch in remember to connect the two wires in the correct electrical terminal.Turn the key to the on position and wait about 10-20 minutes for your computer to recongnize the new switch and program it into it's memory and your car should start right up.
YEP IF YOU SEE SECURITY LIGHT FLASHING YOUR CAR IS IN THEFT SECURITY MODE WHICH WILL SHUT DOWN FUEL SYSTEM. HAVE VECHICLE CODE SCAN PROBLEM IN THE BCM MODULE.IT WILL TURN OFF FUEL IF IGNITION KEY HAS IN CORRECT RESISTANCE OR KEY WORN OUT.MAKE SURE YOU HAVE FACTORY IGNITION KEYS.DONT GO TO HARD WARE STORES GET EXTRA KEYS MADE.BECAUSE IF BCM ECM AND IMMOBILIZER CANT READ KEY CODE RESISTANCE WHICH NOT IN A REGULAR KEY IT WILL SHUT DOWN FUEL SYSTEM AND CAR WILL GO IN THEFT SECURITY MODE.YOUR PROBLEM IS DEALERSHIP FIX.
If the security light is blinking, then the security system is DEFINATELY the reason why your car won't start. The actual cause of the problem is MOST LIKELY a defective ignition switch that is not sending the information from your key to the computer.
FIRST try a different key if you have more than one for the vehicle. I have had cars towed into my shop simply because someone was trying to use a cheap duplicate key that was cut at the hardware store. These keys are fine for the doors and trunk. They are great to have around in case you lock your keys in your car. However, they do not have the electronics built into them to allow for engine starting.
If you are using the correct key and a second key also does not work. then...
1. set your parking brake (this will disable your daytime running lamps and conserve battery power.)
2. Connect a battery charger to the vehicle battery if you have one, or see if someone can connect to your battery with jumper cables.
3. Turn the ignition to the START position for about one second. Then release the key to the RUN position. DO NOT turn the ignition OFF.
4. Wait about 10 minutes until the security light quits flashing. Turn the key (without turning it off) to the START position again. The engine should start. If it does not, then you will have to get your car towed in for service.
HINT: you may want to try this a couple times to make sure you are doing it correctly before towing.
If it does start, it is recommended that you have your security system checked for fault codes. I have seen this many times, and it only gets worse and does it more often until this method no longer works to get it started.
You will have to use a key to turn one of the door locks or the trunk lock, in order to turn off the factory security system, which will then allow the car to start. If it's an aftermarket alarm you have installed in your car, you will have to consult the user manual for that particular alarm in order to disarm it.
