Keys and Locks
Keyless Locks (SALTO Wireless Locking System)
Princeton University has installed the SALTO wireless locking system on campus to secure most undergraduate and graduate dormitory room doors, Graduate College annex doors and interior and exterior doors on some academic buildings.
Keyless Locks
Locks installed on doors served by the SALTO system require a TigerCard (The University ID card), not a key, to unlock the door. For increased security in dormitories, students must also enter a PIN. Each TigerCard and PIN uniquely qualifies each user to access a particular door. (Students: See the Housing and Real Estate Services Keyless Lock website for directions to access your PIN )
Hot Spots
Users of the SALTO system must present their TigerCard to a Hot Spot from time to time. By doing so encrypted diagnostic data about each lock is communicated to the SALTO keyless lock system. This will ensure the lock continues to function properly. Presenting a TigerCard to a Hot Spot will also update or validate a users security profile insuring proper access. (Students: See the Housing and Real Estate Services Keyless Lock website for policies and procedures regarding student validation dates.)
