I have an 2001 grand prix there was an atempted theft saw the ignition key swith turn tab popted off . vehicle startes for three seconds an shuts off .

Yes it does have a chip, and yes you'll be buying the expensive key or bypassing the system. http://www.diy-gm-security.com/

Relearn for what ? Anti theft system PK3 ? The relearn procedure is three 10 min. procedures for a total of 30 min.
30-Minute Relearn Procedure
Use this procedure after replacing the following components:
?€¢
The passkey III (PK3) keys

?€¢
The BCM

?€¢
The PCM, see important above

Important: This procedure is not available on vehicles equipped with option code (Z49).
If replacing a BCM with an GM SPO Replacement Part, perform the procedure to setup a new BCM prior to the 30-minute relearn procedure.

1. With a master passkey III key, turn ON the ignition, with the engine OFF.
2. Observe the STARTING DISABLED DUE TO THEFT message on the drivers information center (DIC), after approximately 10 minutes the STARTING DISABLED DUE TO THEFT message on the DIC will turn off.
3. Turn OFF the ignition, and wait 5 seconds.
4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

5. With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
6. With a scan tool, clear any DTCs.

Reset is . Turn the key on for ten minutes, off for thirty seconds. Start the car. Relearn is three times this. Start the car after the third time. Have a battery charger on it. The battery gets to low, you have to start over.

The security, antitheft, or passlock light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle.
This link may help you find ways to bypass this or fix it yourself.

Go through the steps to raise the theft alarm. The local dealer can guide you over the phone - usually after verification you're the rightful owner.

are you using a copy of the original key

you need to use the original key for the car

Antitheft and Alarm Systems: Description and Operation
ANTI-THEFT
The passive anti-theft system (PATS) uses radio frequency identification technology
to deter a driveaway theft. Passive means that it does not require any activity from
the user.
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a
permanently installed electronic device called a transponder. Each transponder
contains a unique electronic identification code, with over 72 million billion
combinations.
Each encoded ignition key must be programmed into the vehicle powertrain control
module (PCM) before it can be used to start the engine. There are special diagnostic
procedures that must be carried out if new encoded ignition keys are to be
configured.
The encoded key is larger than a traditional ignition key. The key does not require
batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This module is
located behind the steering column shroud and contains an antenna connected to a
small electronic module. During each vehicle start sequence, the transceiver module
reads the encoded ignition key identification code and sends the data to the PCM.
The control functions are contained in the PCM. This module carries out all of the
PATS functions such as receiving the identification code from the encoded ignition
key and controlling engine enable. The PCM initiates the key interrogation sequence
when the vehicle ignition switch is turned to ON or START.
The PATS function uses the PCM to enable or disable the engine. All elements of PATS
must be functional before the engine is allowed to start. If any of the components
are not working correctly, the vehicle will not start.
PATS uses a visual theft indicator located on top of the instrument panel. This
indicator will prove out for three seconds when the ignition switch is turned to ON
or START under normal operation. If there is a PATS problem, this indicator will
either flash rapidly or glow steadily (for more than three seconds) when the ignition
switch is turned to ON or START. PATS also "flashes" the theft indicator every two
seconds at ignition OFF to act as a visual theft deterrent.
The PATS is not compatible with aftermarket remote start systems, which allow the
vehicle to be started from outside the vehicle. These systems may reduce the vehicle
security level, and also may cause no-start issues. Remote start systems must be
removed before investigation of PATS-related no-start issues.

The PATs key is used on the following Ford family trucks and suvs:

FORD: 1996-2001 MUSTANG, TAURUS
1998-2000 CONTOUR
1998-2001 CROWN VICTORIA

Following are the instructions for programming a blank key (you must have at least one working key for this procedure).

The PAT

1. Make sure you have both keys.
2. Turn on car but don't start. Watch "theft" indicator untils it goes out.
3. Turn off and repeat procedure with second key.
4. After "theft light goes out, insert new key and turn on.
5. Wait until the theft indicator goes off and then turn off switch.
6. Wait thirty seconds. New key is now programmed into security module. Repeat for any other keys.


1. Erase any old codes by entering the factory code.(buttons will light up)
2. Press 1/2 button within 5 seconds.
3. Press 7/8 and 9/0 buttons at the same time within 5 seconds.

To set new code:

1. Enter factory code (numbers will light up)
2. Press 1/2 button within 5 seconds.
3. Enter personal 5 digit code(decide beforehand) within 5 seconds of each previous one.
To unlock all the doors,press the 3/4 button within 5 seconds of the driver door unlocking.
To lock all doors and set alarm system,press 7/8 and 9/0 at the same time.
To disarm or reset a triggered alarm,just enter personal or factory code.

Do not set a code with five of the same consecutive numbers. It's too easy for thieves to figure out.

Deactivating and Activating Autolock

To deactivate the "autolock":
With all doors and tailgate closed but NOT locked,and ignition OFF.
1. Enter 5 digit code
2. While holding 7/8 button in, press and release the 3/4 button.
3. Release 7/8 button
The horn will chirp once if the "autolock" was deactivated
or two times if "autolock" was activated.

To reactivate the system,repeat steps 1 thru 3

Alternate Method To Deactivate And Activate Autolock

Do steps [1] through [5] (below) within 30 seconds or you'll have to do it over. If you have to do it over, wait 30 seconds between attempts.
Close all doors securely.

1.Turn the ignition key to ON.

2.Press the power door UNLOCK control THREE times.

3.Turn the ignition key from ON to OFF.

4.Press the power door UNLOCK control THREE times.

5.Turn the ignition key back to ON .The doors should lock and unlock.

6.Press the power door UNLOCK control. The horn should chirp ONCE to confirm successful switching of the autolock system

Troubleshooting:

The engine does not start and LED remains off.
1. Check PATS system fuses
2. If alarm is fitted check if LED functions for alarm: if not check cigar lighter fuse (also used for LED)
3. If not go to main dealer

Engine does not start: LED flashes rapidly Leave ignition on until the LED starts to flash a 2 digit code: (sequence- pause-sequence)
Check the following codes:
Code flashes:
1:3 Key code not received. Is key screened by other keys or objects? Try different key: if okay then first key is faulty. If not go to main dealer
1:4 Partial code only received. Try again. If not okay use different key. If not go to main dealer
1:5 Key not programmed into PATS. Program key as above using master
1:6 Faulty link between PATS module and EECV Go to dealer .

the ignition swith reads the key chip when key is turned, this is a common problem,the ignition switch will need to be replaced, after replacing the swith reprograming will be needed, to program you will need a battery charger to keep battery from going dead, after installing new switch,turn charger on, turn key to crank then release key leaving ignition on, you will see the dash lights, leave key on for about 15-20 min, until you see theft light go out, if light doesnt go out then repeat process,crank for 2 sec, then leave key on 15-20 mins until security/theft light goes out, hope this helps.

Answer The "change oil" light on a 2001 Grand Prix is reset by pressing the gas pedal three times while the vehicle is in "accessory" mode:

1. Turn the car off.
2. Place the ignition key in the "on" position, without starting the car. That is, turn the key forward to the place right before it fires the engine.
3. Place your foot on the gas pedal and press it all the way down three times, waiting approximately one second between presses.

If done correctly, the "change oil" light will flash repeatedly, and will then reset.

Please note that it is rare to do this successfully on the first try; if it does not work, turn the car off and try the procedure again, varying the wait slightly between pedal presses at each attempt

if the vehicle starts then stops and the anti-theft light is flahing you may need to re-set the pass-key system to do this you will need to atempt to start the vehicle and when it stalls leave the key in that position and watch the anti-theft light. it should flash on and off for about 5 to 10 minutes. when it stops flahing turn the ignition to off then try to restart your vehicle

I have 07 Pontiac Grand Prix, the wrong key was inserted into the ignition the other day. Now when I try to use the correct key it will not insert completly in the ignition, goes in until last 1/4in of key. Im stuck, I bought the new lock cylinder but how do I get the old one out? I cant get the key to insert all the way so I cant get it to the "On" position, it will not turn at all. The key that was inserted in error is whole and nothing is missing it seems like there is something stuck. Any help would be appreciated...
