This problem happens over and over. The truck will turn over but not start due to the Security System. Have spent a lot of money just to be told it is only the security system. How can I disable or bypass the system?

    well cant get my truck to start ...Security light come's on  and wont let me start../

    The truck will start but then die immediately, I found that if I jump the fuel pump relay contacts the truck will continue to run. What I haven't been able to find out is what is supposed to hold the relay on. A wiring diagram is the only way to solve this problem, which seems to be pretty wide spread judging by this web site. If and when I find a diagram I will let you know where I found it.

The way that i was told how to do a quick fix for is to hold the key in the electrical start and the actual start up of the engine and hold it there tell the security light is solid and then turn off the truck then bring it back to that point and let it blink until it turns off then you can start the truck.

Your security system is a very complex piece of kit and it links in to several circuits in the truck /doors /hood ignition etc and without the correct wiring diagrams it is almost impossible to bypass
a main dealer or auto electrician with diagnostic facility is sadly your only way around this problem
i know from experiance after nearly 2 days and a box load of connectors and wire !! chris

My 96 caprice classic vats security system has y car shut down. I had a after market ATS security chip also in my car and I removed it thinkingvthat was the problem. It wasnt.


OK. Turn on the key, let the light start flashing. Leave the key in the ON position. Leave it that way for 10 minutes. The VATS security is supposed to discourage a thief from stealing your car. It will flash for 10 minutes and then it will stop flashing. Now,,,,,, DO NOT turn off the key. DO NOT turn it off. Simply take ahold of the key and crank the car up. It will start and should never happen again, unless someone removes the instrument cluster, the battery, or other vital items like the ECM PCU. Good luck.

I have a 1999 Pontiac Grand Am why won't my car start? it just spins but wont crank. I changed the core packs and it's still not cranking


The term " CRANK" is what the Starter is doing to the Engine. I think you mean is 'it Cranks but wont Start'.
Is the engine getting Spark? Is the engine getting fuel? You need to check these two things before randomly swapping out parts.
If it's fuel starvation.. Check the fuel pump relay or possibly a bad Fuel Pump.

2008 Chevy Avalanche. Cranks, but why won't it start?


There is no magic fix button provided as standard equipment on your vehicle. You will need to perform standard diagnostic procedures to ascertain the source of the failure to start.
Begin by doing a readout of all stored codes from the ECU. This will give you a starting point from which to proceed in diagnosis. Check all systems, including FUEL, IGNITION, and SECURITY.

How can I get the security light to turn off


To bypass the factory security would be difficult or car thieves would have a field day!

your best bet would be to get a replacement alarm key fob and disarm the vehicle that way!

How to bypass passlock on 1999 chevy blazer


The most common repair is to replace the ignition lock cylinder due to broken wires inside the steering column. Most common problems related to the Passlock family involve the Passlock sensor. The sensor is part of the ignition lock cylinder on Passlock I and Passlock II systems. ( Where the key goes ), Good-Day!

I hooked up the jumper cables wrong to a Mini Cooper 2005 and it wont start. What should I do?


load test the battery. Test the alternator with a multimeter, it should read between 13.3 and 14.6 volts dc. Test the alternator at idle and rev the engine to 2000 rpm. The multimeter probes are place on the battery terminals. Look for corrosion between the battery and the battery clamps. Baking soda cleans the corrosion.

2001 explorer sport wont start after being disabled possibly by toying with the transmission linkage.


As far as I'm aware the dealer has to make your security key for you. It sounds like you don't have the proper key so it will only function the interior and not start the engine as a security feature so that people can't make copies of your keys and steal your car. If you get a key from a dealer & it works, I would demand your money back from the locksmith. Hope this helps

When I turn my ignition to the start positon the headlights and the dash lights come on but no crank the security light is blinking but not to sure if that is the issue I think it could be my starter,...


if the security light is blinking, it's the VATS system not recognizing the resister pill in the key. I currently have the same non start issue, but I bypassed the VATS ignition key but the car still doesn't start. My security light acts like it should. It comes on when the key is inserted and goes off after 5 seconds. If it blinks, it's not seeing the right value.

Google VATS system bypass. Resistors cost me about 3 bucks at radioshack.
