The shift lock works by requiring you to have your foot on the brake pedal and the key in the ignition turned to ON to move the selector out of Park.
There is both a cable from the keyswitch and a solenoid which together control the release of the selector.
1. Check fuse #5 in the fuse box next to the steering wheel to see if it is blown.
2. Have your keyswitch interlock cable checked and adjusted.
3. Have your brake pedal switch checked and adjusted.
