The process of adjusting a locking mechanism for a different key is called rekeying.
Unlike fully replacing a lock, rekeying allows for the locks to remain intact while just being adjusted to accommodate the new key, making it an efficient and cost-effective solution.

Although the process is relatively straightforward for those with basic knowledge of pin and tumbler locks, it may take some time and practice to perfect, as even the slightest error can cause damage to the lock.

To successfully rekey a lock, you will need the current key, the lock itself, and the new key you wish to use. While some deadbolts can be disassembled with ease, others like door knob locks are more complicated. Hence, locksmiths need to carry a range of tools, including a catch tool, spanner, and plug follower (commonly called a follower).

Utilizing these tools correctly will ensure a smooth and successful rekeying process.
