A guest key has a defined role
Being permitted to stay somewhere does not necessarily mean you can approve a permanent hardware change. Contact the host or property manager if that is unclear. Our authorization notes explain the difference between identifying the door and establishing the person who can approve work on it.
Keep managed access separate
The village describes a resident All Access Card for its Waterfront Park and 102 Street Beach Access Path. Those are village-managed amenities, rather than private locks. The same distinction helps when explaining a residential request: identify the dwelling hardware separately from a common entrance or managed access device.
Say what happened to the key
A key left inside, a key never handed over and a key that has stopped turning are different accounts. For home lock support, mention any existing fault and another authorized entrance you can already use. Avoid repeated attempts if the key or lock feels strained.
Agree on the result with the owner
Immediate entry and changing future key access may require separate decisions. If the owner wants previous copies to stop working, include that goal when discussing suitable hardware. Call with the Bal Harbour address, unit and approving contact to check availability before planning around the request.
