The answer below is correct BUT< <<>>> Stop at step #4 and try and start it up.It always works on my 03 Grand Am GT. As for bypassing the Passlock, you need a module that's sold in the USA to do that, costs about $100...Happy trails from Crazyted
HOW CAN I BYPASS SECURITY SYSTEM ON A 2000 GRAND PRIX GT - CAR WILL START FOR 2 SECONDS AND CUT OFF - ALL 3 KEYS (INCLUDING VALET KEY) WILL NOT WORK
Not to add to the questions, but I have had the same problem with my 2003 Pontiac Grand Am GT. This is what I've learned over the last 26 hours. The PassLock security feature in these cars becomes unstable over time. Some of the contributing issues include worn keys (yes your car key being worn out can cause this issue), the wires to your BCM (Body Control Module) located behind the black plastic "kick plate" under your glovebox may be disconnected, frayed, damaged, or corroded (these little black boxes are about $400). Before you head out and start spending cash like you've got it... try these simple steps to make certain that it isn't' a "learning issue" with your car's computer system.
1) Try to start the car and let the key rest in the "ON" position. If the "SECURITY" light is on or blinking, leave it be and continue to next step.
2) Leave the key in the "ON" position for 15 minutes (they recommend 10, but why take a chance of missing it by a few seconds and having to restart the entire process again).
3) Turn the key to the "OFF" position, but leave it in the ignition and wait 5 seconds.
4) Turn the key back to the "ON" position, but don't try to start. Let set for another 15 minutes.
5) Turn the key back to the "OFF" position and wait another 5 seconds.
6) Turn the key back to the "ON" position and wait 15 more minutes. DO NOT TRY TO START YET>
7) Turn the key back to the "OFF" position for yet another 5 seconds.
8) NOW turn the key "ON" and try to start. If the BCM has learned the new value for the resistor in your key, it will fire up without any further issues.
NOW.... If this does NOT work... you've got the same issues that I have. I've received numerous suggestions on what to do from this point. Here is a list of the possible culprits, starting with the easiest and least expensive.
1) Fuses (check them all, both sides of the dash panels and under the hood)
2) You can actually bypass the BCM by pulling out the middle wiring harness and isolating the black and yellow wires. Expose a small portion of each by cutting away the wire insulation and soldering a 2.2k resistor (should be easily found at Radio Shack for under 2 bucks). Solder the ends to each wire and wrap with electrical tape. You've just bypassed the $400 PassLock system and fooled your car into accepting the new value. You'll have to do the same procedure as above for the computer to learn the new value, but it does work on 97% of the vehicles they've tried this on.
3) Replace the BCM, mine is made by Delphi and they are VIN specific, so you'll need to take your vehicle's id number with you to the dealership. They cost about $400 and are easy to replace (3 wiring harnesses snap onto the top and are color coded). This fixes almost all of the issues and doesn't leave that annoying "SECURITY" light on.
Hope this helps and if you have ANY questions, please feel free to contact me at CaptAdams35@hotmail.com with "PONTIAC" in the subject line.
ok you have to check the ohms on the key for reistance ( so 2.2 wont always work and you may need to put a relay in so the resistance goes on and off like you were removeing the key since some computers will think you left the key in the ignition and will keep it from starting or running)
You can't, it is part of the body computer.
The factory alarm system can not be disabled or bypassed. Any failure would need repaired.
where is the security system located on a 1996 jeep grand Cherokee
hey mate i have a 1997 jeep grand Cherokee and had the same problem.. its your idle sensor.. all i did to fix it was disconnected the battery for 30 mins.. i already did that, she will not turn over Did you shut off the security system by using the key or the remote? The engine will not run as long as the security is triggered.
The 2003 Pontiac Grand Prix does come with a factory security system installed. If your security system is enabled it should have a "security" light that flashes when the key is turned on.
There never was a 1974 Jeep Grand Cherokee.
Removing the security system of a 1993 Jeep Grand Cherokee can be done in less than 30 minutes. You will need to take out the Vehicle Theft Security System Module and all sensors. Make sure the battery is disconnected before removing.
that is not going to be possible because gm has a anti-theft system on all grand am's 1999 and newer and if you try and steal it it will run for a few seconds then die and the security light will come on and disable the fuel pump
Yes. When your GM security system activates, it disables fuel delivery to prevent startup.
pull it out of the box to bypass the centrifuge
I need to know how to bypass the anti theft system pass key on a 1997 Pontiac grand am. my car will start but goes dead. wont remain running
turn the key in the door lock
If it is a factory (OEM)security system. Go to passenger door and lock/unlock 2 times to clear/reset fact security system. If your battery is weak or toast you need to replace or problem will continue .
I am a gm service manager and there have been no security system recalls on 02 grand ams i have a 2002 grand am as well and my security systems keeps acting up it will activate then i cant use car because it wont turn off then i have to get it towed in and they reset it they showed me how to but it still doesn't work for me No need for a tow you sit in your car for 10 minutes until the security light goes off then you can start your car again. Its poor parts that GM choose to use. I love my Grand Ams ( on the 5th one)
Pull the fuse.
try resetting security system
Put the key in the driver's door (from the outside), and unlock the door. That resets the security system.
No, it is hardwired into the ecm and the rest of the car.
have same trouble i would like to know myself
how i can reset the security sistem for a Pontiac 2001 grand am
A bad starter can cause a Mercury Grand Marquis to not start. A bad alternator or a problem with the security system can be the cause for the car not starting.
download a beat out saved file or type in carl bypass the sheep
Sometimes my sons 2001 Grand Am does that. It has to do with the Security System. Turn the key to ACC the Security light will start blinking and will continue to do so for 10 minutes. At that time the Security Light will stay on. At that point you can start you car. This works for him Good Luck.
