A new home feels like a clean start, but its keys have been around. Builders, sales staff, site supervisors, trades and cleaners may all have held a key or had access through a lockbox. Rekeying before you move in makes every earlier key useless.
Who might hold a key
During construction and closing, keys often pass through several hands. Some builders use construction keys that are replaced by a final set, but that is not always the case, and you cannot know how many copies exist. The simplest answer is to assume more keys exist than you were given.
Rekey, don’t replace
A rekey changes the internal pins so that only new keys work, and it keeps the existing hardware. It is usually faster and less costly than replacing every lock, and it lets you keep a matching set. Ask for all exterior doors to be included: front, garage entry, back door and any patio or side door. Garage remote codes and keypads should also be reset.
Check the doors
New homes settle in the first years, and doors that closed easily in the first month can start to bind. At the same visit, check that each door closes squarely, that the bolt goes fully into the strike, and that the weatherstripping seals. Small alignment issues are easier to fix now than after winter.
Consider a smart lock
If you plan to add a smart lock, do it at the same time. Confirm the door’s backset and thickness, and make sure it closes cleanly. See smart lock installation.
Keep track of keys
Once rekeyed, count your keys and note who has them. Keep a spare at home, stored securely. If you rent part of the home later, plan separate keys for each entrance.
Ordering
When you call, say the number of doors, the lock brands if known and when you’re moving in. We’ll confirm availability and price before starting. See the Milton page for more.
