Problems with Metal Key Systems
Traditional metal key lock systems are vulnerable in a variety of ways. 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, the locks are often not re-keyed due to the cost and
time requirements. An experienced criminal can study several keys or look inside the
key cylinders and decode the key system, allowing him to create a grand master key
to the property.
Benefits of Onity Electronic Locking Systems
Onity locks do not require re-keying if a guest keeps a card. Each new guest card
issued automatically re-keys the lock to prevent access by the previous guests, so
your guests are secure. Additionally, the guest cards will expire at the date and time
designated during check-in. There are no mechanical parts able to be decoded that
will allow criminals into the rooms; the lock is unlocked only through an encrypted
code. Onity locks also store the most recent openings in non-volatile memory,
allowing the hotelier to know exactly who has been in the room, and when.
