The ignition key contains a coded transponder chip which is read via an antenna around or close to the ignition/steering lock and the code in the key must match the code in the car's immobiliser memory in order to start the car.

As the key came from a different car it will need recoding. Sometimes the chip is moulded in plastic and sometimes it is possible to take the key apart - in that case you should be able to fit the chip (like a grain of rice) to your new key.

If you are lucky placing the original key close to the new key while trying to start might just make it work.
Good luck!

SOURCE: No start / start/ anti theft light?

MAY BE YOU HAVE A DEFECTIVE KEY, CHECK IF THE KEY HAS A PELLET IN IT, IF SO THE KEY IS BAD AND YOUR DEALER CAN REPLACE IT.
THE PELLET IS A RESISTOR FOR THE ANTITHEFT.

SOURCE: 99 chevy cavalier theft system light on steady, car wont crank.

My 2000 cavalier has done this for 6 months. You take your key out then open your door, wait ten minutes and the system resets itself and the car will start-annoying you bet!!!

SOURCE: My 2005 Malibu anti theft indicator no longer

It's when the security light starts flashing that the infamous "chip" in the key becomes a nightmare to many. Gradually the car begins not cranking anymore or if it cranks it would start and die in a second. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car
1st trick, Try a spare key that is newer or used less. The pins wear down and so do the keys causing security fail. 2nd trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shutting down while running, im sorry i have no quick fix... If anything on this page helps you, please remember to comment or give me a thumbs up on the myfixya sight so i can have a better rating to help more people on this. Thanks

Cheap fix: Bypass the chip in your key. Temporary, but effective. Until the TDM (theft deterrent module) in the dash poops out, then you're kinda screwed. I was told that these types of key security systems have a 7-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.
----- http://vats.likeabigdog.com/


Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did to fix the problem. They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... Anywhere from 600-1000 bucks. If you do buy this, please purchase it thru this link. The cost is the same, but i get credit for the sale and im trying to earn my money back, as you will be able to do if you buy fron NewRockies and join the free affiliate program. Thanks
----- http://newrockies.ca?ap_id=judd0081 ----- With this fix, you can take that whole Vats, passlock, passkey system out of your car all together. Good info on both sites.

It works for:
Any GM or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.

Lost the key to my 05 trail blazer bought a new switch with a key it still won't start unless I jump it with a wire

Hello. It seems the new ignition switch/lock cylinder won't 'communicate' with your vehicle's anti-theft system; causing it not to start/run normally. That ignition switch/lock cylinder must be 'programmed' by a 'certified' locksmith shop. They have equipment to 'pair' the switch and your car's anti-theft system together. Good luck and keep me informed; if you want to.

Where is the anti theft module located at in a 2005 Kia Sedona? Van won't start and read online a lot of complaints about Kia vehicles is the anti theft module kept the vehicle from starting.

The anti-theft function is part of programing in the ECU. there is no external module. The ignition switch is not reading the key. Do not hang a bunch of trinkets and keys from your key ring. 2 keys at the most. See if the dealer can make you a new key. You may have to replace the ignition switch as well. Perform OBDII scan for anti-theft codes.

I PUT MY KEY IN THE IGNITION AND MY CAR WONT START AND I TOOK OFF THE WHOLE IGNITIONG AND PUT ONE IN FROM THE JUNK YARD AND EVERYTHING TURN ON IN THE CAR BUT THE CAR WONT START WHAT CAN I DO TO MAKE IT...

The ignition key and the ignition switch are part of the anti theft security system. The anti theft system has been triggered and the ignition system will no longer start the car. The only way to get it working again is to take it to a dealership and have them install a new ignition switch with matching key and control module. These three parts plus labor will cost you at least $1,000.00.
