Can I access the TSA PreCheck® lane by showing my Global Entry, NEXUS, or SENTRI card or TSA Pre✓® approval letter?

No. To receive TSA PreCheck®, you must include your Known Traveler Number (your CBP PASSID for Global Entry, NEXUS, or SENTRI members) in the appropriate field of your airline reservation, and the TSA PreCheck® indicator must be  displayed on the boarding pass to access the lanes.
