Transponders are purchased in the Management office with a check/money order (cash, credit, or debit cards are not accepted at this time). Basic vehicle information (make, model, year, color and license plate number) is required.  If you do not have the license plate number readily available, the transponder will be set to expire after 30 days until the Management office receives that information. Windshield transponders are $20.00 and headlight transponders are $20.00. Some vehicles require a headlight transponder.  After receiving a receipt from the Management office, the gatehouse installs the transponders Monday through Friday from 8am - 12pm and 12:30pm - 3:45pm. No appointment is necessary.
