When you keys have been stolen or misplaced OR if you just moved to a new home.
Changing the locks when your keys have been lost or stolen is VERY IMPORTANT.
If your house keys are ever stolen, one of your first orders of business is changing the locks on your doors so no one can gain access to your home. Rekeying is the method of choice in this situation, just as it would be if a family member misplaced a key or otherwise lost track of it. The one instance when you’d need to replace the entire lock is if the only key to the lock went missing. The rekeying process requires the use of an original key; if you don’t have one you’ll have to replace the entire lock.
Rekey when you move.
When a new house is under construction, a variety of people—including subcontractors, inspectors, and real estate agents—will have keys to the door. A new homeowner won’t want keys in the hands of all those people, so the lock should be rekeyed. This is typically a part of the sales process (and the responsibility of the builder), although the buyer’s real estate agent is the one who makes sure it’s complete before closing. Rekeying is a good idea any time you move into a different home because you never know how many keys are floating around. When you’re buying an existing house, you’re on the hook for having the locks rekeyed. If you’re renting, check your lease agreement for regulations about changing locks on a door—you may be required to give the landlord a key to the newly rekeyed lock.
If your current locks are outdated, consider upgrading to high-security locks. Rekeying during this upgrade enhances your home's overall security, providing advanced features to protect against modern threats. Always hire Charlotte Locksmith experts for more details regarding security issues.
