What did you do with the original key . it is a chipped key with security code embedded to turn off the security system .

    then you need to take the vehicle to your local dealer and get the code for the car matched to the column not something you can do .

2013 Chrysler 200 won't start and the security is the only light staying on.. What could this be


try another key. the vehicle is equipped with a "smart key", the one you are using may be bad and not signaling the security system to allow start-up. The solid red means the vehicle is not reading the security chip in your key.
If you have another key try it.
Is the battery and connectors good? Low cranking amps will not signal the security system to shut of.

03 tahoe not starting abslamp security lamps lit no check engine lite


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.

Check your security light on the dash and see if it stays on or blinks with the key in on position. If so google how to reset the security.

I got a 1999 chevrolet tahoe. when i put the key in the ignition the head lights,and the dash light comes on but it won't even turn. i change the starter and got a new battery and it still won'


well if you have a dvom/voltmeter check the power at the starter terminals. the main terminal should have power all the time the key wire should have power only when the key is turned to crank engine. if you have power at both then i would start looking at grounds

98 cherokee turns over but won't start no power to wiring at fuel pump an on the dash ther is a orange key with a line throw it what does it mean


This indicator light is related to the vehicle security system, which checks that the key you are using is authentic. If it is flashing, you have a key with no chip in it, a bad ring antenna, or other fault in the security system.
Instructions
    • 1Turn the ignition switch off.
    • 2Insert the key into the driver's side door.
    • 3Turn the key clockwise to lock it.
    • 4Turn the key counterclockwise to unlock it. The alarm system recognizes an authorized key was used and the system resets.
      As a side note if that doesnt work try it in the rear hatch. good luck hope this helped.

My 2000 corvette won't crank up---no lights will come on-----nothing works in dash, not even the radio


I would take the battery cables loose and actually verify battery is not leaking. If "security" is causing no start then you can tell by watching the security lamp on dash. It should be on solid when key is turned to run if it is part of your concern. also sounds like you could have a body control module problem it controls the interior lamps which may explain clicking you heard and also controls the security.

Keep us updated.

Cherokee won't start it cranks but won't start and security light comes on


i dont know if this helps, but i know in some models, the security issue is caused by the key itself. if there is an rfid chip in the key and it is not responding to the computer, the motor will not start. try using your VIN to get a new key made at a dealership.

if it is causing this you can tell by observing the security lamp whie cranking engine(top of dash left hand side near v.i.n. plate.if you have a solid red light while key is on or cranking engine then this an indication of fault with anti theft key system.if the lamp is out you need to look elsewhere.these cars are notorious for crank and cam sensor failures.good luck and please let me know how it works out.

Electronic chip in key


As far as bypassing the securtiy chip, we can't tell you that one as it would assist any user on here to steal your car (or others).
When you turn the key to attempt to start it do the dash lights dim or even go out ?
