How can I bypass the security code


Why do think the key security is bad? If you still have a factory key, this is not the problem...if no factory key, you can take your VIN number or original key to GM dealer to get new key that they will program for you...Check for dirty battery connections:)

2002 impala, no crank


what makes you think someone tried to steal it? the security light issue is a very common problem with GM cars equipped with the Passlock II anti-theft system. just a few days ago my 2003 impala did the same thing in front of a 7-11. took me about 10-15 minuts to get it started. i just kept turning the key on, tried to crank it, and turned the key off numerous times. i had a 1999 malibu that did the same thing and i replaced the ignition cylinder and keys. that cost me about $160 but it solved the problem. changing it out is fairly simple. if thats the route you have to/ need to go i can walk you through it. unfortunately however, GM, although this is a very common occurance, will not issue a recall to fix the problem.

1998 chevy silverado. will turnover. new fuel pump, has fuel pressure., . won't start.


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.

I have a 2002 chevrolet impala and it does not want to start.the security light is on. is there something i can do to make it work again


usually if security light comes on means ur alarm system is being triggered. wrong key. or wont recognize the code from the ignition cylinder. try opening the ignition on for 10 seconds. turn it off and try crank the engine again.

Wouldn't start. Turned ignition switch. Nothing happened. Interior lights & headlights worked.tried 2 hours later & car started.


Does your security light flash if you turn your key to the 'on' position? If so, this is a Passlock problem. It should restart after 10 minutes. Here`s a possible solution that has worked for me. Have a new key cut from origional key or best condition key you have. Buy some Electronic cleaner and spray lots into the lock cylinder. Then, put your key in the ignition and turn from off to on position several times (5 to 10 times quickly). Then remove your key and spray again and repeat key turning. Do this several times. I don`t recomend any spray that is oil based. I no longer have issues with my Passlock system and I have almost 500 000Kms on my Impala.

How do i dis arm the anti security theft system after installing a new shifter and key tumbler?


Put a battery charger on the battery. Turn key to the on position for 15 minutes. This will relearn the theft system and you will now be able to start and run the car.

2001 chevy impala security light keeps coming on


This is a problem with chevy vehicles that have the system theft light. after a couple of years of using the key, the lock tumblers inside the ignition switch tend to wear out and so causing the system to think it's being stolen. Now you have to put the key in and turn the ignition to the on position, without cranking the car and leave it for 10 minutes until the theft light goes out. Very annoying especially if you're in a hurry. The dealer cost to repair the ignition switch goes for about $600-$800. that includes re-teaching the key.

2002 Chrysler Sebring Convert wont turnover


If you're not hearing a click from the starter check for a starter relay. May be burned out! DO you hear the fuel pump kick in when you turn the key on? If not something might have triggered your security system and locked you out!

Resetting the security system in a 2002 chevy impala


does your key have a small black chip at the base of the key if so it could be bad or the ignition could be bad it reads a resistance and if it is off by a few points it will think that the car is being stolen
