Why You Should Change Your Locks After Moving House

Two stick figures are carrying a simple black house with a white outline and door, set against an orange background—a visual reminder of why you should change your locks after moving house.

Why You Should Change Your Locks After Moving House in Bournemouth

You’ve just got the keys to your new home – but do you really know who else has a copy?

Whether you’ve moved into a flat, house, or rental in Bournemouth, Poole, Christchurch or beyond, changing the locks is one of the most important – and overlooked – steps in securing your new property.

At JCarter Locksmiths, we help homeowners across Dorset protect their families and their homes with fast, affordable lock changes using high-security cylinders.

Who Might Still Have a Key?

Even if the previous owner seems trustworthy, you can’t be sure how many keys were made – or who might still have one.

Potential Key HoldersRisk Level
Previous owners or tenantsMedium – especially if no locks were changed
Estate agents or letting agentsMedium
Cleaners, contractors or dog walkersHigh – often unsupervised access
Family or friends of previous ownersUnknown – risk of unauthorised access
Old tenants (for rentals)Very high – especially in HMOs or student lets

When to Change Your Locks

You should always change the locks when:

  • You’ve moved into a new property (owned or rented)
  • You’ve bought a flat or house from someone else
  • You’ve taken over a holiday let or Airbnb
  • You’re a landlord preparing for new tenants
  • The locks look damaged, stiff, or outdated
  • You’ve had a breakup or divorce

Top 5 Reasons to Replace Your Locks After Moving

1. You Have No Idea How Many Copies Exist

Even if you’ve been handed a full set of keys, you can’t know how many duplicates have been made in the past.

2. You May Not Be Covered by Insurance

Some insurers won’t pay out if there’s no sign of forced entry and your keys were used to gain access.

🔗 Aviva and Direct Line recommend lock changes after moving home

3. You Can Upgrade to Anti-Snap Locks

Standard Euro cylinders are often vulnerable to lock snapping – a common burglary method in the UK. We recommend TS007 3-Star locks, like the Avocet ABS.

4. Your Door Could Be Outdated or Insecure

Older UPVC and composite doors often have worn mechanisms or no anti-bump protection.

5. Peace of Mind

The most important reason – knowing you and your family are the only ones with access.

Can highly recommend J Carter Locksmiths. They gave me a reasonable quote for a new door lock mechanism and 2 double glazed windows which just needed the glass replacing. They did a great job so I used them again to replace a rotting door on a garden cabin. Again they did a brilliant job and cleared up afterwards.

Jake and Joel of J Carter Locksmiths have fixed my stuck balcony door and replaced blown windows in my 4th floor flat this June 2026. They responded quickly to my job request, they were efficient, courteous and tidied everything away afterwards. Their charges are very fair and competitive. I highly recommend them and would definitely use Jake and Joel again.
