When it comes to home security, there are two major ways to secure your locks: rekeying and replacement. Essentially, lock rekeying includes resetting the lock's pins to a different combination.

Whereas replacing locks involves replacing the existing lock with a new one. But the question is, which is better: lock rekeying vs. replacement?

Choosing between both of these options may be challenging and depend on several factors. But do not worry! In this blog, we will discuss the differences, benefits, and cons, as well as when and how to rekey and replace a lock.

Lock Rekeying vs. Replacement: What’s the Difference?

When it comes to home locks, many of us use the phrases rekeying and replacement interchangeably, but there is a crucial difference. Rekeying a lock means changing the pins and springs inside the lock so that it can only be opened with new house keys.

The lock assembly remains inside the door. Homeowners typically rekey their door locks when they need a new key or if the original key is lost or stolen. On the other hand, replacing locks entails replacing the complete locking mechanism with a new one.

A locksmith replaces the entire lock assembly on a door. This is commonly done when the lock has worn out or no longer functions properly. Homeowners may also change locks if they want a whole other model of lock.

Pros and Cons of Rekeying Locks

After comparing lock rekeying vs. replacement, it's crucial to understand the pros and downsides of each.

Pro: Rekeying is a cheap option.

Starting with rekeying the lock, one of the most significant advantages of this method is that it is significantly less expensive than replacing the entire lock. The cost of rekeying a simple lock ranges from $20 to $60. More complex locks may cost more to rekey, but it is still a reasonable price to pay for home protection and peace of mind.

Pros: Rekeying is quick and simple.

Rekeying a lock is also considerably faster and simpler than replacing the entire lock. Depending on the type of lock and the locksmith's ability, rekeying can take as little as 10 minutes.

Con: Rekeying will not fix a malfunctioning locking mechanism.

When it comes to the disadvantages of rekeying your locks, it will achieve nothing if the lock assembly itself begins to show indications of wear and tear. If your home door lock is sticky or fails to secure a door reliably, it has to be replaced.

Pros and Cons of Replacing Locks

Like rekeying, replacing your locks also has advantages and disadvantages.

Pro: Replacing locks can improve your home's security.

If your door locks are damaged and no longer operate correctly, replacing them might help to make your home more safe. You can also choose from a variety of locks, such as standard deadbolts, keypad locks, smart locks, and biometric locks.

Pro: Replacing locks can improve your home's security.

If your door locks are damaged and no longer operate correctly, replacing them might help make your home safer. You can also choose from various locks, such as standard deadbolts, keypads, and intelligent and biometric locks.

Con: Replacing the locks on new house doors might be costly.

Better home security comes with a cost. Changing the lock entrance may be costly, depending on the type of lock assembly. You will have to pay for the locksmith's time and expertise and the new lock, which might be costly if it is more technologically advanced.

When to Rekey and When to Replace a Lock

After comparing lock rekeying vs. replacement, the next question arises: when should a lock be rekeyed and when should it be replaced?

In most circumstances, rekeying a lock makes more sense than replacing it entirely. Rekeying is frequently a cheaper solution that provides a high level of protection. It will usually suffice if you move into a new home and your key is lost or stolen.

If your lock mechanism is beginning to weaken, consider replacing it. You can swap it with a similar model while keeping the same set of keys. Alternatively, you might upgrade your locks to increase security.
