Does key have a resistor built in?
Are you using an original key, or a replacement that has the proper security computer chip located in the fat plastic part of the key? If not, the car's security system will keep the ignition locked and will not allow you to turn the ignition switch. ALSO: some earlier models of Focus had ignition switches that were a problem. If you ARE using the correct key and can't turn the switch to start the car anymore, the ignition switch may have to be replaced.
Tampering or replacing ignition that does not match up with your key will cause your security to shut your car down.
One common cause for the security light to come on is the chip in the GM ignition key. First try the spare (if you have it) if that does not work it may be the contacts inside the ignition. I am not sure if it can be repaired or if the ignition must be replaced. I have heard that the problem can escalate to cutting out the motor, so it is not something to be ignored. If your ignition key does not have a black piece of rubber with a small piece of metal in it, just disregard what I said. I hope that this information will help you get to the bottom of the problem.
Disabling the keyless ignition security lock on a 2007 Saturn can be done by programming the security locks. Turn the ignition to run, without actually starting the engine, and press the unlock switch for eight seconds.
You replace the ignition cylinder and then turn the ignition (with key) to on position. All dash lights will light up in the on position. After a few seconds only the security light will flash. Leave the ignition on for 10 minutes while the security light flashes. At the end of the 10 minutes the security light will go out. This will be the first cycle of reseting the E.C.M. to read the new cylinder and ignition system replacement. At this point you do this process two more times. This will take proximately 30 minutes. At the end of all three cycles the car should come on. If you want someone to walk you through it E mail me at archuleta67@gmail.com.
If your security light is flashing, then you have had what is referred to as a "bad timing cycle" with your Passlok security system. Turn the key to the ON position, and wait until the security light stops flashing - This takes exactly 10 minutes.If the security light WAS flashing, then the 10-minute trick is only a temporary fix - You will need to have your ignition switch replaced.
how do I set reset ignition security on a 1999 z34 monte carlo
the Grand Am ignition switch also houses the anti-theft sensor for the "security" light. the switch sensor in my 2000 GA went out a couple of years ago, and it cost a bit over $400 to have it replaced. i'd imagine the 2001 would be about the same.
The security light comes on after you changed the keys in the ignition from the off position to the on position as a confirmation that the electrical components in the dash board are working. It is nothing to be concerned about.
