Why Rekeying Your Locks After Moving House Is One of the Smartest Security Decisions You Can Make

Moving into a new home is an exciting milestone. Between unpacking boxes, organising utilities and settling into a new neighbourhood, there's plenty to think about. One important security step, however, is often overlooked. Rekeying your locks.

Who Might Still Have a Key?

When you buy an existing home, there's usually no way of knowing how many copies of the keys have been made over the years.

Previous owners may still have a spare key tucked away. Former tenants, family members, neighbours, cleaners, tradespeople or property managers may also have been given access at some point.

Most people are honest and would never misuse a key.

The issue isn't about distrust—it's about certainty.

Rekeying gives you complete confidence that only your new keys will unlock your home.

What Is Rekeying?

Many people think the only way to secure a home is to replace every lock.

In many cases, that's simply not necessary.

Rekeying involves changing the internal pins inside your existing lock cylinder so it works with a brand-new key. Once completed, all previous keys become useless.

The lock itself remains on the door, but only your new keys will operate it.

It's an effective way to improve your home's security without replacing quality hardware that still functions perfectly.

Rekeying vs Replacing Locks

If your locks are in good condition, rekeying is often the most practical option.

It typically costs less than replacing every lock and can usually be completed much faster.

Lock replacement is generally recommended when locks are damaged, worn out, outdated or when you're upgrading to a different style of lock or improved security features.

An experienced locksmith can assess your existing locks and recommend the most suitable option for your home.

Can All Your Locks Work with One Key?

One of the biggest advantages of rekeying is convenience.

In many homes, several external doors use different keys.

During the rekeying process, these locks can often be configured to operate from a single key, making everyday life much simpler.

Instead of carrying multiple keys, you'll only need one to unlock your front door, back door and side entrance.

When Should You Rekey?

Moving house is one of the most common reasons to rekey, but it isn't the only one.

You should also consider rekeying if you have:

• Lost your keys

• Recently ended a tenancy

• Experienced a relationship change

• Had keys stolen

• Completed renovations with multiple tradespeople on site

• Moved into an investment property

• Purchased an older home

Any time you're unsure who may still have access to your property, rekeying is worth considering.
