If possible, have a friend/family member with a second set of keys to your apartment let you in. Otherwise, call the office and select the emergency option to have staff open your apartment for you. During business hours, Monday to Friday there is a $25 charge for letting you back in. Outside of business hours there is a $50 charge.
If you lose your keys to your apartment, send in a maintenance request for an additional set to be made. The cost for this can range from $20 to $100, depending on if your lock needs to be replaced.
