If you replaced the ing. switch then then it has to be relearned to the pcm via a scan tool.

I tried to turn key cylinder radio comes on car won't start security light on can i bypass ? i already turned off alarm with door key. husband already lost job because of this we cant afford to fix


The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

Oil Light is on need to Reset it. Don't have manaual.


Do you mean the "Oil" light or the "Oil Life System" light?
.
If the oil light is on, you need to stop operating the engine and have it checked to find out why the light is telling you that there is no oil pressure.

If you mean the Oil Life light, Then here are the instructions:

How to Reset the CHANGE ENGINE OIL Message

1. With the ignition key in RUN but the engine off,

fully push and release the accelerator pedal slowly

three times within five seconds.

2. Turn the key to OFF.

If the CHANGE ENGINE OIL message comes

back on, the engine oil life monitor has not reset.
Repeat the procedure.

2000 pontiac montana doesn't start and security light appears on dashboard


Very common problem on these cars. Do you have another key you can use? Try it. If not take the key ou have been using and turn ket to the on posistion. Leave it there on for ten to fifteen minutes. The computer will relearn the chip code on key. When light stops blinking you know it is done. Turn key to off wait ten to fifteen seconds and turn key to on position, Security light may blink once or twice then it should stop.. Try to start vehicle. It should start. If it doesn't then you may need whats called a new passlock and possibly key reprogramming. Which can only be done at the dealer most of the time. Hope car starts with the first procedure. Let me know if it works.

Most likely the passlock sensor will need replaced and the key reprogrammed unless you recently replaced a key that never got programmed listed below is detail instructions on reprogramming a the passlock to the key.

there is a way to bypass the system we do it often but you will need to buy a data bypass unit to install in order to bypass the passlock sensor in the dash. Once the unit is installed, it is turned on by inserting the key into ignition, then the unit will send the proper code to the BCM allowing it to unlock the ECM and then car will start.
