Understanding Rekeying
Rekeying involves modifying the internal components of an existing lock so that old keys no longer operate it. the lock itself remains installed, but the internal pin configuration is changed, allowing a new key to work.

- A completely new key is issued
- Previous keys become unusable
This process allows property owners to regain control over who has access without replacing the entire locking system.
Benefits of Rekeying

What Is Lock Replacement?
Lock replacement involves removing the entire lock and installing a brand-new locking mechanism. This means both the internal and external hardware are replaced.
What Happens During Lock Replacement?

- Remove the existing lock
- Install new hardware

Advantages of Lock Replacement
Many property owners choose replacement because it allows them to:
- Upgrade to stronger security features
- Install modern lock designs
- Switch to smart lock technology
- Replace worn or damaged locks
- Improve the appearance of doors and entrances
For older homes, replacing outdated locks can significantly enhance security.
When Rekeying Makes More Sense
In many situations, rekeying provides everything you need at a lower cost.
1. Moving Into a New Home
When you purchase a property, you may receive keys from the previous owner. However, there is no way to know how many duplicate keys exist or who may still have access.
Rekeying immediately after moving in provides peace of mind and helps ensure that only your household can enter the property.
This is also a great time to organise other moving-related tasks such as professional cleaning services, utility connections, and security upgrades.
2. Lost or Stolen Keys
If you’ve lost your keys and believe they may be linked to your address, rekeying is often the fastest way to restore security.
Instead of worrying about who might find the keys, rekeying prevents old keys from working altogether.
3. Tenant Changes in Rental Properties
Landlords and property managers frequently choose rekeying between tenancies.
Benefits include:
- Improved security for new tenants
- Lower costs than replacing locks
- Faster turnaround between leases
- Better access control
Combined with professional end-of-lease preparation, rekeying helps ensure the property is ready for its next occupants.
4. One Key for Multiple Locks
Many homeowners prefer carrying a single key rather than several.
A locksmith can often rekey compatible locks so they all operate using one key, making access simpler and more convenient.
5. Locks Are Still in Good Condition
If the lock hardware is functioning smoothly and shows minimal wear, replacement may not be necessary.
Rekeying delivers the security benefits you need without the expense of new hardware.
When Lock Replacement Is the Better Option
There are situations where replacing the lock is the smarter long-term decision.
1. Damaged or Worn Locks
Locks naturally deteriorate over time due to weather exposure and regular use.
Common warning signs include:
- Difficulty turning keys
- Rust or corrosion

2. Upgrading Home Security
Modern locks offer significantly improved protection compared to older systems.
You may want to upgrade to:
- High-security locks
- Restricted key systems
- Deadbolts
- Keyless entry systems
- Smart locks with mobile access
For families looking to improve overall household safety, replacing older locks can be a worthwhile investment.
3. After a Break-In
A break-in can damage locks or compromise their effectiveness.
Even if the damage appears minor, replacing affected locks is often recommended to restore confidence in your home’s security, a recommendation frequently made by advanced lock & key after security incidents.
Many homeowners also take this opportunity to improve outdoor lighting, security cameras, and property maintenance measures.
4. Renovations and Home Improvements
During renovations, many people replace locks to match updated doors and hardware.
This creates a consistent appearance throughout the property while improving security at the same time.
