How to program key to ignition for a 1998 Chevy truck w/vortex v6 engine..I tried it myself an it did crank but will not stay running


Program KEY ? There is no transponder in the key for a 1998 Chevy truck . What problem are you have ,no start ? Is the SECRUITY light lit on the dash ? you don't need to program keys with this ant-theft system .
Vehicle Theft Deterrent (VTD) Operation
The design of the passlock system is to prevent the vehicle operation if the proper ignition key is not used in order to start the vehicle. The mechanical key, in normal operation, will turn the passlock lock cylinder. The passlock sensor will relay the passlock data to theEVO/Passlock module. The EVO/Passlock module will determine the validity of the passlock data. The EVO/Passlock module will send a code password to the vehicle/powertrain control module (VCM/PCM). When the VCM/PCM receives the correct code the VCM/PCM allows the fuel injectors to operate normally. The passlock system requires the VCM and the EVO/Passlock module to communicate the various functions in order to operate. These functions transmit over the class 2 serial data line CKT 1807. For an explanation of the class 2 serial data operation refer to Data Link Communications Circuit Description in Wiring Systems.
Passlock System
The design of the passlock system is to prevent vehicle theft by disabling the engine unless the passlock lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the passkey system. However, the passlock eliminates the need for a key mounted resistor pellet. The components of the system are as follows:
?€¢
The ignition lock cylinder


?€¢
The ignition switch


?€¢
The passlock sensor


?€¢
The EVO/Passlock module


?€¢
The security indicator


?€¢
The vehicle/powertrain control module (VCM/PCM)

96 buick skylark starts & stalls, theft light on not flashing. Dissconnected map sensor still starts & stalls. No chip in key, changed fuel filter. whats goin on here?


This is pass lock antitheft system not pass key, pass key system is found on newer gm vehicles and has a transponder in the key. Pass lock system has a hall sensor on the lock cylinder.
System Operation
If the mechanical key is not used to start the vehicle, the PASSLOCK?"¢ system is designed to prevent vehicle operation. The mechanical key, in normal operation, will turn the PASSLOCK?"¢ lock cylinder. The PASSLOCK?"¢ lock cylinder will relay a Resistance Code (R-Code) to the instrument cluster. Within a preset time window started from an ignition switch input and will send a coded password to the powertrain control module (PCM). The instrument cluster will determine the validity of the R-Code. For the fuel injectors to operate normally, the powertrain control module (PCM) receives the correct code

If the theft light is on there is a problem and a code set. You can try to do reset . Turn the key on , don't try an start the car . Let key on for 10 min. till the light goes out, if it goes out turn ignition off an wait a couple of min. then start the car

Anti theft light comes on the car won't start


Your "inmobiliser" system is actived.

The anti-theft feature prevents the car from being started when one of several anti-theft devices is faulty are have otherwise been activated. The problem you descibe might be the ignition swith, which is known to wear out quickly on those models. The system can be completly disabled only when the car is running (meaning the teft deterent system is inactive after the Passlock II system detects the proper key in the ingition). A wire can be cut that would perminantly disable Passlock II, meaning any key that opens the door (or a screwdriver) could start the car. If the ignition swtich goes out or this wire is cut while the engine is off (theft deterent system is active) then the car will have to be towed back to the dealer to have the ignition system replaced and reprogrammed.

I have called Chevy and asked how to fix this problem. If you turn the key to the on position, right before it cranks when the lights and radio turn on. Leave it there for ten minutes until the anti theft light turns off. Then turn the key to the off position and then try starting the car.

Rumour has it that it is a yellow wire to be cut. Do more research, but D O N ' T cut it with the engine off. See first paragraph above.

Hope this help (remember rated and comment this). Good luck.

Well i put a new starter on the car the the theft light stays on will it fix the problem if i take it to the dearler to put an ingition lock cyclinder in it because my car want start.


Your Passlock may need to relearn the ignition keys, if the ignition lock has gone bad like my in-laws Grand Am Gt, here is what i did so they will not get stranded any more. Buy a Passlock by pass module for around $70.00. You can order one from GMPASSLOCK.COM in the mean time try resetting the Passlock. Good luck

Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure
1.) Turn ON the ignition, with the engine OFF.
2.) Attempt to start the engine, then release the key to ON; the vehicle will not start.
3.) Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF.
4.) Turn OFF the ignition switch, and wait 5 seconds.
5.) Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes.
The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
6.) Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password.
7.) With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.

Without a scan tool you may have momentary starter interruptions while history clears itself. Keep me posted, be glad to know you got your car running 100% again soon.

How do you bypass security system on 97 firebird. If the security light is on the car will not start i need to know how to bypass this. i already had another key made for it that dosent work


HI, PROBLEM AREA ON A WIDE RANGE OF "GM" CARS WHAT IT IS IS THAT YOUR PASSLOCK SYSTEM IS ACTIVATED WHICH MEANS THAT FUEL IS SHUT OFF TO THE ENGINE THEIR IS ONE WAY TO GET AROUND THIS BUT THE PART NEEDS REPLACED YOU NEED A NEW INGITION LOCK CYLINDER THIS HAS THE SENSOR BUILT INTO IT ANYWAYS GET IN CAR TRY AND START IT IT MAY OR MAY NOT ATTEMPT TO FIRE AT THIS POINT LEAVE THE KEY IN THE RUN POSITION AND YOU MUST!!!!!!!!! LEAVE IT IN THE RUN POS. FOR APPROX. 10 MINUTES WATCH THE DASH THE THEFT OR SERCURITY LITE WILL BE FLASHING WHAT THIS WILL DO IS THE BODY CONTROL MODULE LOST MEMORY OF YOUR KEY AND HAS TO RELEARN IT AFTER AFTER 10 OR SO MINS. THE LITE WILL REMAIN ON STEADY MEANING NOT BLINKING ANYMORE TURN KEY OFF THEN TRY TO START CAR.. THIS IS NOT A FIX YOU MUST REPLACE PASSLOCK SENSOR.....
