Is It Cheaper to Rekey or Replace Locks?

Many people opt for new locks when they lose keys or move into a new house. However, it is wise to consider rekeying as a cost-saving alternative. Rekeying involves changing the lock's pin combination, while changing the lock means getting a new one.

Deciding between the two depends on various factors such as budget, turnaround time, security and convenience. However, we will look into those factors to determine the preferred choice.

Rekeying Or Replacing: Which Is Better?

Rekeying and replacing locks are often used interchangeably, but they have great difference. Rekeying means altering the internal pins and springs of a lock to function with a new key while keeping the lock assembly intact. It is typically chosen when you need a new key for the same lock or have lost the original one. Rekeying is more cost-effective since it mainly involves inexpensive key pins, while lock replacement includes entirely new components.

Rekeying is significantly cheaper as it primarily charges for labor, whereas lock replacement adds to the cost of parts.

In contrary, lock replacement demands expertise, and specific tools. The process could be costly, time-consuming, and risky. To avoid such hassles, it is advisable to consult a reputable locksmith, especially since replacement entails installing an entirely new locking mechanism, often done when the lock is worn out or if you desire a different lock style.

When is the Right Time to Rekey Your Locks?

To rekey a lock without incurring extra costs, you'll need the existing matching key. If you have lost your keys (aside from the worry of someone using them) or in case you entered your new house (without any idea of who might have access to your lock), rekeying becomes an excellent alternative. 

Another scenario where rekeying proves beneficial is when you wish to utilize one key on several locks, just for simplicity’s sake. This can be done if the locks are of the same brand or have compatible keyholes.

Is It More Cost-effective To Rekey Or Replace Locks?

Rekeying is usually the most budget-friendly option. In this process, a locksmith adjusts the existing lock to work with new keys while keeping the same hardware.

However, if you've lost the matching key for the lock, the process becomes more complex and expensive.

Therefore, it is advisable to consult locksmiths to assess whether rekeying or replacing your locks is the right choice. This approach allows you to make an informed decision while considering your budget constraints.
