Security light is on my 1999 Chevrolet suburban how to reset it
Passlock on this vehicle shows the key does not have a pellet and no transponder. It's just a mechanical key. It is the tumbler that communicates with passlock sensor. The passlock sensor wiring is noted for problems. Can you check applicable trouble codes?

How to bypass passlock on 1999 chevy blazer
The most common repair is to replace the ignition lock cylinder due to broken wires inside the steering column. Most common problems related to the Passlock family involve the Passlock sensor. The sensor is part of the ignition lock cylinder on Passlock I and Passlock II systems. ( Where the key goes ), Good-Day!

1999 GMC Jimmy Security light
Without the proper testing equipment an knowledge ( factory service info. ) You have no idea what's up . an don't have a chance of fixing this . Checking for DTC'S - diagnostic trouble codes is always the first step . Take's a professional type scan tool to read these codes. Serial data info from module incharge to PCM/ECM ,enable or disable fuel and or starter operation . Sends coded messages Your best bet , take it to a qualified repair shop . That white component is the ignition switch .
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 the body control module (BCM). The BCM will determine the validity of the passlock™ data. The BCM 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/PCM and the BCM 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
