Property Managers and Landlords
Rental property owners benefit from fast rekeying between tenants. According to the Federal Trade Commission, controlling physical access is a foundational step in preventing unauthorized entry and protecting personal property.
Why Rekeying Saves You Time and Money
Lock rekeying is a process where a locksmith changes the internal pin configuration of an existing lock so that a new key operates it while old keys no longer work. This is significantly cheaper than replacing entire locksets. LT Lock and Key offers dedicated lock rekeying and master rekeying services for both homes and businesses.
For landlords managing multiple units, master rekeying allows a single master key to open all doors while each tenant keeps a unique key for their own unit. This streamlines property management without compromising security.
