Lock Rekeying: Understanding the Process and Its Necessity

Lock rekeying is a cost-effective and efficient solution that enhances security without replacing the entire lock. It involves changing the lock’s internal pins and tumblers to render old keys ineffective. In this article, we will delve into the process of lock rekeying, its benefits, and situations in which it becomes necessary to rekey locks instead of opting for a complete lock replacement.

Understanding Lock Rekeying

Lock rekeying is a process that alters the lock’s internal mechanism to work with a new set of keys while rendering the old keys useless. During rekeying, the locksmith disassembles the lock, replaces the existing pins and tumblers, and configures them to match a new key’s pattern. This eliminates the possibility of previously used keys opening the lock. The new keys are then provided to the owner, ensuring exclusive access to the rekeyed lock.

Situations Requiring Lock Rekeying

  1. Moving into a New Property: When moving into a new home or office, it is advisable to rekey the locks. You cannot be certain who might possess copies of the existing keys. Rekeying the locks ensures that previous occupants, contractors, or other individuals with access to the keys are unable to enter your property without your knowledge.
  2. Lost or Stolen Keys: If you lose your keys or they are stolen, rekeying the locks is a crucial step in maintaining the security of your property. Rekeying ensures that the lost or stolen keys are no longer functional, preventing unauthorized access. It is a more cost-effective solution compared to replacing all the locks.
  3. Tenant Changes: For landlords or property managers, rekeying locks between tenants is essential. It provides peace of mind knowing that the previous tenant no longer has access to the property. Rekeying allows you to grant new tenants exclusive access, without the need to replace the entire lock hardware.
  4. Employee Transitions: In a business setting, when an employee leaves or is terminated, rekeying locks can safeguard the premises. It prevents former employees from potentially gaining unauthorized access to sensitive areas and protects the company’s assets and confidential information.
  5. Enhanced Security: Rekeying locks can be part of an overall security upgrade. If you have concerns about the integrity of your existing locks or want to improve the security of your property, rekeying provides an effective solution. By rekeying the locks, you can upgrade to higher-security options, such as installing locks with more complex keyways or electronic access control systems.

Benefits of Lock Rekeying

Lock rekeying offers several benefits, including:

  1. Cost-Effectiveness: Rekeying is often more cost-effective than replacing all the locks, especially when multiple locks are involved.
  2. Enhanced Security: Rekeying ensures that only authorized individuals possess the new keys, preventing unauthorized entry and maintaining the security of your property.
  3. Time Efficiency: Rekeying is typically a quicker process compared to completely replacing locks, resulting in minimal disruption to your routine.
  4. Convenience: Rekeying allows you to have a single key that operates multiple locks within your property, improving convenience and ease of use.


Lock rekeying is a valuable process that enhances security and provides peace of mind. Whether you have moved into a new property, lost keys, experienced tenant or employee changes, or desire enhanced security, rekeying offers a cost-effective and efficient solution to ensure the integrity of your locks and protect your property.
