Why Changing Locks Is Non-Negotiable
When you move into a new property, you have no way of knowing who else has a key. The previous owners may have given copies to relatives, neighbours, cleaners, tradespeople, or estate agents. Even if the previous owners assure you they have collected all keys, there is no guarantee.
Changing the locks on every external door is the only way to ensure you have complete control over who can enter your new home. It is a small investment that provides massive peace of mind and is recommended by police, insurance companies, and security professionals.
When to Change Your Locks
Ideally, you should change your locks before you move your belongings into the property. This ensures that from day one, only you and your family have access. If this is not possible, schedule the change as soon as possible after moving in.
Do not forget to change locks on all external doors, including the front door, back door, side doors, patio doors, and garage doors. Also check any gates or outbuildings that contain valuables. If you are moving into a rental property, discuss changing the locks with your landlord, as many are willing to do this for new tenants.
What Locks Should You Install?
Moving house is the perfect opportunity to upgrade your security. Rather than simply replacing old locks with identical ones, consider upgrading to high-security options.
Recommended Lock Upgrades for a New Home
- Install TS007 3-Star anti-snap euro cylinders on all UPVC and composite doors.
- Fit British Standard BS3621 mortice locks on wooden doors.
- Add a high-security deadbolt or night latch for extra protection.
- Consider upgrading to a smart lock for keyless convenience.
- Replace garage door locks if the garage connects to the house.
- Install a key safe for emergency access and spare key storage.
How Much Does It Cost to Change Locks on a New Home?
The cost of changing locks when you move house depends on the number of doors and the type of locks you choose. A basic lock change on a single door costs between £70 and £140. If you are changing all external locks on a typical three-bedroom house, expect to pay between £250 and £500 for standard locks, or £400 to £800 for a full high-security upgrade.
Many locksmiths in Hampshire offer a moving house package deal that includes changing all locks and a free security assessment. This is often the best value option and ensures consistent quality across all doors.
What Else Should You Check When Moving?
Changing your locks is essential, but it is not the only security consideration when moving house. Take the time to check these additional items:
Moving House Security Checklist
- Check window locks on all ground-floor and accessible windows.
- Test the alarm system and change the code if one is installed.
- Replace any security keypads or codes the previous owner may have known.
- Check if any spare keys are hidden outside the property.
- Inspect the condition of all doors and door frames.
- Consider a full security survey to identify vulnerabilities.
- Update your address with your home insurance provider.
