Lock your door with the keyless entry (If you have it) if not just lock all your doors, pop your hood and shut all the doors. Then remove the negative off your battery for about 30 seconds minimum. Then reconnect the negative of the battery, close your hood, unlock the drivers door with either the key or the keyless system if you have it, and try to start your car. If that does not work then it is not your theft system but a bad grounding of your battery.

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)

Car wont run


The passlock anti-theft system is possibly not working properly, if the passlock thinks you are trying to start the car with anything but the key it will kill the fuel pump power within 10 seconds.
The problem may be as simple as an ignition key cylinder exchange.
