A missing house spare can wait for a decision
Being able to enter the house gives you time to think about who might still hold a copy. Count the keys you can account for, identify the doors they operate and speak with the owner or responsible manager before arranging a change. The aim is a clear access plan, not replacing hardware simply because a spare has disappeared.
For suitable existing locks, rekeying may be worth discussing. A loose cylinder or a latch that already catches is a separate concern; mention it rather than assuming a new key will solve both problems.
Keys visible through the window?
Tell us whether the vehicle is locked with the key inside, whether the key has been lost, or whether a fob is present but not working. Have the make, model and year ready. These details help distinguish an automotive access request from a replacement-key question; the exact vehicle still needs to be checked.
Keep any remaining key with you. If another person is bringing a spare, say so before agreeing to work, and confirm who owns or is authorized to use the vehicle.
A place and a meeting point
The city lists Betty T. Ferguson Recreational Complex on NW 199th Street. A name like that can help explain your location, but the actual parking area, street address and the vehicle itself are more useful than a landmark alone. Share where you can meet without moving into a restricted or unsafe space.
Our entrance and meeting-point guide explains the same distinction for nearby Opa-locka. If the property is actually in Miami Lakes, give that location instead. Call 786-706-9100 with the address and request to discuss availability and the proposed work.
