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.

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.

If all else fails and the vehicle won't crank disconnect your negative and positive cable then have someone turn key on and touch the positive and negative cables together for 3-4 second then connect them back to battery and then crank the vehicle. This seems to shock the system and is a quick fix

SOURCE: car wont start

In most instances, bypassing the passlock system is not possible. One thing you may want to try is take your car down to the dealer and have them reflash the computer, less the theft deterent system.

My 96 chevy caprice security fault light is on and car turns over starts but does not stay running. The fuel pump seems like its being shut down. How can I fix this problem?


The fuel pump isn't being shut down , the engine computer isn't seeing a anti-theft system pass word (code) so it disables the fuel injectors . The security light on ? DTC'S - diagnostic trouble code's are stored . Need a factory or professional scanner to read this code's . You could try a by pass of the key an lock cylinder ,but that may not be the problem . Does your key have a resistor pellet on the side of the key >

You really need to have the lock cylinder changed, but you will need to have the new lock cylinder re-pinned to the original key for the VATSS system to register the key and allow the vehicle to start.

How to buy pass the anty lock


You may not be able to bypass the anti-lock system if you bought your car from a buy now pay now kind of place because they will shut down your car if your payment is late.

If you are talking about the system automatically locking your doors when you start the car, you cannot do that either because it is a safety feature.

The security light is flashing and the car wont start how do i fix it


May have a fault in the VATS. Most likely the wires that come from the ignition lock are broke. That is the weak link of the VATS.
Need to measure the resistance of the pelet n your key and basically add that value of resistors to the wire for the lock cylinder at the bottom of the column where they come out.
If you do a search for "VATS bypass" you should find diagrams of how to do this. (This is mistakenly refered to a VATS bypass while it really is not a bypass. The Pass Key module always stays in play. It just bypasses the weak link in the system.)

How do you stop the security light from blanking trac off light from coming on and theft fault system from poping on when driving in a 2001 aurora after replacing the factory radio? In: Oldsmobile Aurora...


For the radio Im pretty sure you just need to call your dealer or go see them, they will take your VIN and give you a code to keep your after market stereo from kicking the theft lock.

The security light unfortunatly is a very common, and as it is just annoying right now, potentially big problem. The model Pass Key system in th 01 Olds Aurora tends to be defective in most of these cars. If the Security light, or DIC is flashing Theft fault system, you need to see your dealer. Chances are your secureity system is about to have some "Lock out" Malfunctions. These are no fun. Its when the Pass Key system detects a suspicious or uncorrect key trying to start car or someone is trying to enter car abnormally. Its actaully a very good feature when opperating properly. It usally lock the system for 3-10 minutes and the system resets and with the correct key you can start the car. The problem is that the little chips in the keys go bad causing the "lock out" to happen even when usuing the correct key. Anouther, less used key can work better, and if you start expieriencing lock outs, waiting to the system to reset usally works, but eventually those mthods will fail to and you will have to have it repaired. This system can also cause the "lock out" to occur while driving down the road.

Id get it checked and fixed before the neusance light become a real problem.

You can also consider a Bypass system that with completly go around the smart key system. They are inexpensive and effective and preventing issues with the Pass Lock. However you will not have the security settings from the Immobalizer (lock out) so it would be a easier target for joy riders. You will still have the theft deterant ability, that alarms if someone tried gaining entry to the car with out keys or proper entry methods.

Bypass systems are not full proof either and do wear out over time. I think they have far less issues than the securtity feature in the car and if the bypass fails and Lock Out occurs, simply get a new Bypass. Hope I helped a bit take care :-)

SECURITY LIGHT COMES ON WHEN DRIVING,EVERYTHING IS OK BUT AFTER MAYBE 4 OR 5 TIMES OF SWITCHING OFF THE ENGINE, NEXT TIME TO TURN KEY TO START ENGINE TURNS BUT FUEL IS SHUT OF. PASS LOCK OPERATES. WE THEN...


The most common reason for this condition is a faulty ignition switch. It loses contact momentarily while cranking, causing a voltage loss to the security system and starts the 10 minute security timer in the computer. It will not start until the timer runs out. Usually the key has to be left on after a start attempt for the ten minutes. Some cars require 30 minutes. I hope this helps you and please rate this,
