95.5-97 Troopers:
Note that the "box" referred to is usually located directly under the steering wheel/dash area. It is black, about 4x4 inches, and likely fastened under or near the steering column. Get your head down by the pedals and look up to see it.
-- START --
Assuming this is the original keyless system, there is a white label on the top of the box. The label is covering over the hole. (We usually access the box by removing the small cover in the left area of the lower dash panel and using a long screwdriver.)
Push around in the middle of the label and tear the paper thru the hole. Inside there is a square yellow button.
Key on, key off, push and hold the button until you hear two tones or the horn beeps.
Release the button and momentarily press the "lock" icon on the remote. You'll hear a confirming tone or beep.
Key on and off again. Try it to see if it works.
Keep in mind nothing will arm or lock if a key is in the ignition switch while you're testing.
