The previous owners, their family, dog walker, cleaner and contractor may all hold copies of your new keys. Rekeying makes every old key useless while keeping your existing locks — it is a practical first security upgrade for a new homeowner.
Do it for every exterior door, and ask for one key to work them all. While there, check that each entry door has a working deadbolt with a reinforced strike plate.
Good time for upgrades
Move-in is the natural moment to add a smart lock to the main entry or standardize aging hardware. HSI Locksmith provides new-homeowner rekeying across Broward, Palm Beach, Martin and St. Lucie counties.
