    I guess I didn't post this comment few days ago as I thought I had...but surprisingly my Yukon does not have the security pass type keys just the regular key and fob but there was an aftermarket remote starter put in and then new fob's were programmed at the time and given to me which I no longer have either one (one was lost awhile ago and the other was with the set of keys stolen) so do I need to find out what specific remote starter is in there and locate the type of fob I need from there or would any gmc fob with aux button be able to be programmed to my truck? also would this then make the old one no longer useable by whom ever stole my keys if they tried using it after new fob is programmed? does that question make sense?

Most Gm use a chip in the keys. the doors with be easy to ,but the ignition will not. you will need to go to the dealership and have them remove the lock from the ignition and re program the new key

2001 ford taurus key won't turn ignition


The steering wheel was turned when the key was removed. So when you try to turn on the key, turn the wheel one way and the other way to release the pressure on the key. The key should turn ok.
Hope this helps.

Security light on dash & radio in "locked" mode


The security light 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) The TDM is what tells your computer that the correct key is being used and that it is "OK" to allow the vehicle to start and run. These 3 parts must be in CONSTANT communication. If the key is in the ignition, then these parts are sending important signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, (normally due to a failing/broken part) the car goes into antitheft mode. The car misinterperates this and thinks its being stolen or hotwired because it is NOT getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle. So basically, if that light is on, your system has some sort of failing part. This can start as an intermittent "no start", to your vehicle not running for days at a time, to the vehicle NEVER starting again. The problem is electrical and computer based, so don't count on an easy reset button, or the problem fixing itself. The hard part is isolating which part is the problem. You can spend a thousand dollars through a mechanic very easily. I have had great luck with bypassing the entire system. This way the problem will never return. It actually CAN'T ever return because it is eliminated. This can also be done yourself at a much cheaper cost. Read through this link very carefully. You'll find alot of information and pictures, along with ways to help you fix this.

Starter wont engage, jumped starter with key on but dies immediately. repaced ignition switch and starter relay. even tried 2 extra spare keys. security light is flashing


This is a pretty common problem on GM vehicles. This is what is happening. Your vehicle has switched itself into ANTITHEFT mode. 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 to the ignition's lock cylinder, and then to the car's TDM. These 3 parts are in CONSTANT communication. If the key is in the ignition, 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 goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle.

I went to my car this morning opened the doors with my key put my key in the ignition and it would not lock into place or take the steering lock off or start the car


I had the same problem when I borrowed my father in law's C class 2000. I have replaced the battery, cleaned contacts inside the key, nothing. Had to get taxi home and get a spare key. My father in law has replaced it but I don't think the problem was so simple to enable to find easy exit.

Ignition switch stuck will not turn wont ether way


Two causes for this:
(1) steering wheel needs to be turned, then try key again.
(2) faulty ignition switch in need of replacement (including a new set of keys).
When starting a car, the ignition is locked if the wheel has been rotated, which is an anti-theft
feature: the car thinks its being stolen when the wheel is turned while there's no key in the ignition.
To fix: turn the wheel back and forth, returning it (one way or another) to the original position
when the car was turned off, and unlocking the ignition, allowing you to start your car.
