When there’s a change in ownership of a property, the new owners usually plan to rekey or replace the locks. If the home has been previously owned, the new owners will not know who has access to the keys, unlike in new homes where contractors are the ones with access to the keys. If rekeying the locks is chosen, the locksmith removes the pins and springs in the lock cylinder and replaces them with new pins and springs that work with a new key. Many locks can be rekeyed and kept in service unless they are not working properly or a different style is required. However, in most new communities, locks are mastered with extra pins left in the lock, which means that numerous different keys could operate a single home’s locks. When these master pins are rekeyed, the possibility of another key operating the locks is eliminated.
There are circumstances in which locks must be replaced. Over time, locks wear out and rekeying may no longer be an option to improve their function. Upgrading the locks you have is always a good idea because your home’s locks are what protect you and your property. You may also want to replace your locks for aesthetic reasons or to accommodate disabilities. For example, lever handle locks are attractive and easy to operate, and deadbolts are available with an interior thumb turn that is operated without grasping.
