Why Rekeying a New Home Is Not Optional

You just closed on your home in Port St. Lucie. The realtor handed you two keys. You think you are the only one with access. You are almost certainly wrong.

During the listing period alone, the lockbox code was shared with potentially dozens of agents. The previous owners had keys made for family members, dog walkers, house cleaners, pool service, lawn care, and neighbors. Contractors who did work on the house may have copies. A single misplaced key could be floating around for years.

What Rekeying Actually Does

  • New Pin ConfigurationThe locksmith changes the internal pin arrangement of each lock cylinder. The existing hardware stays - only the pins change. All old keys immediately stop working.
  • Key Alike OptionAll locks in the house can be rekeyed to use the same key. Front door, back door, garage entry, side door - one key opens everything.
  • Same Day ServiceA mobile locksmith completes a typical home rekey in 30 to 60 minutes. No need to remove locks from doors or take them to a shop.
  • Cost EffectiveRekeying costs a fraction of lock replacement. You get new key access security without paying for new hardware.

What to Rekey First

Prioritize exterior doors that provide access to the home. In most Port St. Lucie homes, this includes the front door, garage-to-house door, back sliding door (if keyed), and any side entry doors.

Interior doors with keyed locks (bedroom, home office, closet) can be rekeyed at the same visit if desired. Garage door opener codes should also be reset - this is separate from the lock rekey but equally important.

Who Might Have Your Keys Right Now

  • Previous owners and their family members
  • Real estate agents who used the lockbox during showings
  • Contractors, painters, cleaners, and landscapers hired by previous owners
  • Neighbors who were given a spare key for emergencies
  • Property management company (if previously rented)
  • Previous tenants if the home was a rental property
