Losing a key has a way of creating more questions than answers. Who might find it? Does somebody still have an old copy? Should the locks be replaced altogether? These are the situations we deal with every day at Open Locksmiths.
In many cases, replacing the entire lock isn’t necessary. A professional lock rekeying service can often restore security by changing the lock’s internal key combination while keeping the existing hardware in place. The old keys stop working, new keys are issued, and access is back under your control.

Understanding How Lock Rekeying Actually Works
One of the most common misconceptions we hear is that a lock must be replaced whenever security becomes a concern. While there are situations where replacement makes sense, many locks are still mechanically sound and simply need their access credentials changed.
A lock rekey service involves disassembling the lock cylinder and modifying the internal pin configuration so that the existing keys no longer operate the lock. Once the new pin combination is installed, a new set of keys is cut to match. From the outside, the lock looks exactly the same, internally, however, it has become a completely different lock from a keying perspective.
This process is commonly used after moving house, losing keys, ending a lease agreement, changing staff access, or purchasing a commercial property. In many cases, rekeying achieves the same security outcome as replacement while avoiding the cost of new lock hardware.
When Rekeying Makes More Sense Than Replacing Locks
Not every security issue requires new locks. In fact, some of the most expensive lock replacement jobs we come across could have been solved with rekeying alone.
The real question isn’t whether the key is missing, it’s whether the lock itself is still in good condition. If the cylinder operates smoothly, the hardware remains secure, and the lock still meets the property’s security requirements, rekeying is often the smarter option. You retain the existing hardware while eliminating access from previous keys.
This is particularly common when:
- Moving into a newly purchased home
- Taking possession of a commercial property
- Managing tenant changeovers
- Dealing with lost or stolen keys
- Restricting access after staff departures
- Addressing security concerns following a relationship breakdown
- Updating access control after contractors have completed work
Many people don’t realise how many copies of a key can accumulate over time. Previous owners, tenants, tradespeople, property managers, cleaners, family members, or former employees may all have had access at some point.
A professional rekeying service in Melbourne helps remove that uncertainty. Rather than wondering who might still have a working key, you start fresh with a completely new key combination and full control over property access.

Frequently Asked Questions
Is rekeying as secure as replacing a lock?
If the existing lock is in good working condition, rekeying is generally just as effective from an access-control perspective. The internal pin combination is changed, meaning old keys no longer work. The main difference is that you keep the existing hardware rather than replacing it entirely.
Can all of my locks be rekeyed to work with one key?
In many cases, yes. If the locks use compatible cylinders and keyways, they can often be configured to operate from a single key. This is commonly referred to as keyed-alike rekeying and is popular in both residential and commercial properties.
How long does a rekeying service usually take?
The timeframe depends on the number of locks involved and their condition. A straightforward residential rekeying job can often be completed during one visit. Larger commercial systems, restricted key setups, or multiple access points may require additional time onsite.
Should I rekey the locks after buying a house?
Most locksmiths would strongly recommend it. You rarely know how many copies of existing keys are still in circulation. Previous owners, tenants, tradespeople, real estate agents, or contractors may still have access. Rekeying gives you a clean slate and immediate control over property security.
