20 Most Recent 2003 Chevrolet Malibu Questions & Answers


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.

The resistor is located on the left front bumper support.To access the resistor on Chevrolet and Pontiac models, loosen the left front corner of the plastic wheel well liner where it attaches to the front fascia. Saturn vehicles do not require you to remove the front wheel or wheel well liner.

Locate the brake cable along the frame near the rear wheels. You'll find the adjustment there.

Check for blown head gaskets. GM aluminum-head engines are VERY UNFORGIVING when it comes to being overheated. The heads usually warp, resulting in blown head gaskets and repeated overheating like you are describing. One of the main symptoms will be that you fill the cooling system and open the bleader screws to get the air out of the system. Then you start the engine and run it until the cooling fan comes on. When the fan comes on, place your hand behind the cooling fan and see if the air coming through the radiator is HOT. If it is blowing cool air, the coolant is not flowing through the radiator like it should. This is usually caused by high pressure in the cooling system due to combustion gasses getting in.

Plugged catalytic converter , take it to a qualified repair shop an have it properly diagnosed .

Well when you replaced the battery did anything else on the key fob work? Often times you have to reprogram the remote in order for it to function properly. Try getting inside the vehicle and manually lock all doors with the driver's side switch. Put the master key in the ignition switch and turn the switch to the run position but do not start it. Now push and hold the lock and unlock buttons at the same time until the locks make noise....may take 10 to 30 seconds. After you have the key fob programmed, see if the alarm will turn off with the remote. Did it work? The only way to totally turn off the alarm is with a GM Tech @ or 3 scan tool and go into body control bidirectional controlling procedures or with a very good aftermarket scanner with good bi-directional functionality.
The alarm works via the body control module on this vehicle and i am thinking it uses the PK2 system and if you do not have a properly coded key or the BCM is loosing memory, then check for any and every blown fuse and replace as needed.to start with.. If the vehicle stays running after starting then the bcm/key is reading correctly.

Check the idle air control valve for carbon buildup. Also check for a vacuum leak.
