Locks are important in keeping your home safe. But how often do you think about changing them? Many homeowners and business owners only consider a lock replacement when they experience a lock malfunction or security issue. However, regularly updating your locks is important.
Whether you’ve lost a key, moved into a new home, or your locks are simply worn out, knowing when to replace them can help prevent security issues and give you peace of mind. Here, we look at when and why you should update your locks—and when it’s time to call a locksmith for professional help.
Key Reasons to Change Your Locks
There are several situations where a lock replacement is necessary to keep your property secure. What’s more, over time locks become more advanced and offer better security. After a time, your current lock likely won’t be as secure as modern equivalents. And sometimes locks are redesigned because burglars have found new ways of disabling a lock, for example when anti-snap locks were created to help stop a growing trend of forced entry through lock-snapping.
Here are other common reasons to update your locks:
· Lost or Stolen Keys – If your keys go missing, you can’t be sure they won’t end up in the wrong hands. Changing or rekeying your locks is the safest solution
· Moving into a New Home – Even if the previous owner or tenant handed over the keys, you never know how many copies exist. Replacing the locks ensures that only you have access
· Break-Ins or Attempted Burglaries – If someone has tampered with your locks, they may no longer be secure. Upgrading to high-security locks can help prevent future incidents
· Change of People – If someone moves out, you should assume they may still have a copy of your key. A quick lock change prevents unauthorised access
· Old or Worn-Out Locks – Locks naturally wear down over time, becoming easier to pick or break. If your lock sticks, turns loosely, or looks damaged, it’s time for a replacement
When Should You Change Your Locks?
There’s no universal rule, but as a general guideline, homeowners should consider a replacement every 5–7 years. However, certain factors can speed up the need for a change:
· High-Traffic Areas – Businesses, rental properties, and shared housing may require more frequent updates. If multiple people have had access over time, security can be compromised.
· Your locks are outdated and there are more secure ones available
· Smart Lock Users – If you have a smart lock, software updates and occasional replacements are necessary to ensure continued security.
· Recent Security Upgrades – If you’ve added a new alarm system, cameras, or other security features, updating your locks to match the new system makes sense.
If you’re unsure whether your locks need replacing, a quick search for a locksmith near me can help you find a professional to assess your security.
Smart Locks vs. Traditional Locks: When to Upgrade
Upgrading your locks doesn’t always mean replacing them with the same type. Many homeowners are switching to smart locks for added convenience and security.
Traditional locks don’t require power or internet, making them a solid choice for those who prefer a simple, mechanical lock.
Smart Locks offer keyless entry, remote access, and smartphone alerts. They are ideal for homeowners who want advanced security and flexibility.
If you frequently lose keys or want remote access to your property, a smart lock might be a great investment. Otherwise, a high-quality deadbolt with a strong strike plate remains a solid security option.
Cost Considerations and DIY vs. Professional Installation
Lock replacement costs vary depending on the type of lock and whether you install it yourself or hire a locksmith.
DIY lock replacement of basic locks costs £20–£50, and many can be installed with simple tools. However, improper installation can weaken security. Hiring a locksmith ensures the job is done right. Expect to pay £80–£200, depending on the lock type and labour costs.
If your existing locks are in good condition, rekeying them (changing the internal pins so old keys no longer work) is a cheaper alternative.
For maximum security, professional installation is always the best choice, especially if you’re upgrading to a smart lock or high-security deadbolt.
Final Thoughts
Changing your locks regularly is a small step that can make a big difference in your home’s security. Whether due to lost keys, a break-in, or simply aging locks, a lock replacement means you control who has access to your property.
If you’re unsure whether your locks need replacing, don’t wait until it’s too late. Get expert advice and ensure your home or business stays protected.
