Lock re-keying is the process of altering the internal mechanism of an existing lock so that a new key works while the old key does not. The exterior hardware stays the same, but the internal pins (tumblers) are swapped over or rearranged to match a new fresh key. This way, you don’t have to replace the entire lock.
Re-keying can be cost-effective, convenient and secure. We can assess your locks and advise you whether it’s a recommendable option.
How lock re-keying works
When we re-key a lock, the external hardware stays in place. The lock itself remains installed. The only thing that changes is the key that operates it.
Your locksmith will remove the lock cylinder and adjust or replace the pins inside. These pins are what allow a key to turn the locking system. Once this occurs, your lock will operate only with a new key — all your old keys will no longer work.
When should you re-key your locks?
Lock re-keying is useful in the following situations:
- You’ve lost your keys — and any stranger could have found them.
- You’ve recently moved home — and anyone else could have a key to your lock, such as previous owners, cleaners, tenants, houseguests or tradies.
- You’ve just evicted or changed tenants — and they may still have keys to your property.
Re-keying vs replacement
Sometimes we may recommend replacing a lock rather than re-keying. Lock replacement involves removing the entire lock mechanism from the door and replacing it with brand-new hardware, such as a lockset or deadbolt. The old lock is then discarded.
During replacement, our locksmith removes the entire unit from the door, including the cylinder, internal components and sometimes the strike plate. They then install new hardware, which is usually more modern, thereby improving security. A fresh set of keys is also provided.
Replacing a lock is usually a more expensive and time-consuming option, as you are paying for all brand-new parts and more labour. However, it is sometimes necessary and can offer greater security.
Reasons for replacing a lock:
- The old lock is worn out, damaged or broken
- You want to upgrade to premium or smart lock technology
- You need improved security features
- Your locking system is outdated
- You’d like to change the colour of your lock
- You want to match different keys of different locks into one key, but your locks have different brands or keyholes
