|Key Card Access|
If you are locked out or lost your keys, the concierge staff could provide access and then you merely reorder a replacement door key.
This has obvious advantages for rental properties as keys are passed from tenant to tenant over a number of years and potentially dozens could be in play. Using cards makes them annually renewable and provides the security of deactivating a number of cards remotely.
When a Suite is placed for Lease or Sale; typically owners provide the key for the CANADA POST mailbox to use in a lockbox (held at Concierge Desk). Agents [THEY] open your mailbox and retrieve the access card. This creates an opportunity for "OTHERS" to read your mail and it could adversely impede your negotiation position.
Please consider providing and using a FOB. This eliminates one entire step to assist REALTOR showings and still protects your privacy. The Fob is generally programmed for the suite and all common area doors; Gym, Party Room, Billiards etc.
The key itself is maintained in the lock box and Nosey Nellie is not reading your mail.
