smslocksmiths • April 11, 2025

Changing your locks might not be something you think about often — but it's an essential part of keeping your home safe and secure. Whether you’ve just moved house or experienced a security scare, knowing when to change your locks is key to peace of mind. Here are five signs it’s time to take action.


1. You’ve Moved into a New Property

Whether you're renting or have bought a new home in Tooting, changing the locks should be a top priority. You never know how many copies of the key are still in circulation — estate agents, previous tenants, tradespeople, or even neighbours could have access.


2. You've Lost Your Keys

Misplacing your keys happens to the best of us. But if you lose them while out and about, there's always the chance someone could find them and trace them back to your address. Changing your locks removes that risk entirely.


3. You've Had a Break-In or Attempted Burglary

If someone has broken into your property or tried to, your locks may be damaged or compromised. Even if they appear intact, it’s wise to replace them with more secure alternatives to prevent it from happening again.


4. Your Locks Are Old or Damaged

Weathering, rust, or wear and tear can all weaken your locks over time. If you notice difficulty turning the key, loose fittings, or any visible signs of damage, it’s time for an upgrade.


5. You’ve Ended a Relationship or House Share

If you've recently parted ways with a partner or housemate, changing the locks ensures that only you and the people you trust have access moving forward.
