Spare keys may be held by the Concierge on your behalf. This allows family members, guests, contractors or delivery companies to be given access to your apartment. It also helps to deal with emergencies, such as when you have lost your keys. Visitors will be asked to provide identity, and access must be arranged in advance. This arrangement would also allow you to instruct the Concierge team to enter your apartment to deal with emergencies, which could also help to avoid the need for forced entry and the associated repair bills.
