Moving into a new house is an exciting milestone, but it also comes with hidden risks—especially when it comes to home security. One of the most overlooked yet critical steps is changing the locks on your doors.

At 24hrs Locksmith, we often get asked:

“Is it really necessary to change the locks if the house seems secure?”

Our answer is always a confident yes—and here’s why.

Even if the previous owner handed over the keys, you never truly know who else has a copy:

• Former tenants or owners
• Estate agents
• Contractors
• Cleaners or maintenance workers
• Neighbours or friends of the seller

Each extra key out there is a potential security risk. Changing your locks ensures you are the only one with access.

You should consider changing or upgrading your locks:

• Immediately after moving in
• If keys were ever lost or unaccounted for
• If you’re unsure about the lock quality or standard
• For rental properties – especially with previous tenants

In fact, many home insurance policies in the UK require BS3621 British Standard locks for full coverage. If your new property doesn't have them, you may not be fully protected.

When changing locks, we recommend:

• 5-lever mortice deadlocks (BS3621 certified)
• Anti-snap Euro cylinder locks
• Smart locks for modern convenience and audit trails

Our experts at 24hrs Locksmith can assess your property and advise on the best security upgrades based on your location, door type, and insurance requirements.
