Traditional metal key lock systems are vulnerable in a variety of ways when installed on hotels and serviced apartments. A guest may simply keep a key or have a copy made so that he can return to the room at a later time. 

When keys are missing, locks are often not rekeyed due to the cost and time requirements. RUSWIN offers Onity Electronic Locking System. Onity locks do not require rekeying if a guest keeps a card. Each new guest card issued automatically rekeys the lock to prevent access by previous guest, so your guest is secure. Additionally, guest cards will expire at the date and time designated during check-in. The lock is only unlocked through an encrypted code. Onity locks also store the most recent openings in a non volatile memory, allowing the Hotelier to know exactly who has been in the room and when. Onity locks can retrofit most type of locks.
