My 94 buick gs shutoff an now it want turnover an start with key switch but crossout starter it starts but dies rightafter


Sounds like VATS (vehicle anti theft system). There is probably an open wire from ignition switch that reads the resistor in the ign. key. Either replace ignition switch lock or bypass the vats reader with resistance of the same value as key. There should be a thin wire running out bottom of column and plugged in near bottom of column it usually has 2 yellow wires. You can place the resistance across the two plug in contacts to by pass .

Actually meant the security module on a 94 cutlass supreme, cheapest way to bypass


It depends on which anti-theft system yours has . VATS , PASSKEY 1,2etc... your vehicle is not new enough to have PASSKEY 3 . There are videos on you tube on how to by pass it . You need to find out what resistance yours has , go to radio shack or some other electronic store an by that size resistor . Then you need to find the right wires under the dash coming from the steering column ,if your ignition switch is in the column .Then solder the resistor to the two wires . Does you ignition key have the pellet on the side ? The two wires your looking for are white inside a yellow or orange sheath , plastic shield .

By pass security system


if key blade broke in barrell you need to tape the key head close to the ign switch so the immobiliser can get its signal ,,, a decent mechanic should be able to remove broken blade with hooks ,,,, andjust get a new or use your spare key

My security light come on once in a while. The dealer wants to install a new switch, is there any way to by pass this feature? It just seems like another way for them to squeeze another $500.00 out of a...


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, (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 shuting down while running, im sorry i have no quick fix...

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. For a list of cars effected by this problem. See the NEWROCKIES link on the right side of their page......... 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.

----- With this fix, you can take that whole Vats, passlock, passkey **** system out of your car all together. Good info on both sites

Cranks want start


Tricky problem. Small wires go to security box close to the ecm under dash. these are prone to break. The for sure solution is to purchase a pass key bypass box, to take place of the factory box only drawback is, YEA! no more key with resistor .Google passkey bypass , there are several manufactures. Unless there is a problem with the ecm :( Hope this helps
