Many homeowners don’t realise that door locks are not designed to last forever
surrounding areas where the issue isn’t forced entry — it’s simply worn, outdated, or failing locks.
Over time, internal components weaken, keys wear down, and security standards improve. What was considered “secure” 5–10 years ago may no longer offer proper protection today.
How Often Should You Replace Your Door Locks?
As a general rule, replacing your locks every 5 years is a smart and proactive way to maintain your home’s security.
You should consider replacing your lock sooner if:
The lock feels stiff, loose, or unreliable
You’ve recently moved into a new property
Keys have been lost or stolen
The lock is an older or low-security model
You want to upgrade to modern anti-snap protection
For uPVC and composite doors, upgrading to anti-snap euro cylinders (TS007 3-star) is highly recommended.
Why Upgrading Your Lock Matters in London
London properties are a common target for opportunistic break-ins. Many burglars use techniques like lock snapping, which can defeat older or basic euro cylinders in seconds.
Upgrading your lock means:
Stronger resistance against forced entry
Better protection for your family and property
Reduced risk of emergency lockouts
Compliance with insurance requirements
Frequently Asked Questions
Do I really need to replace my lock every 5 years?
Not always, but it’s a strong guideline. If your lock is high-quality and well maintained, it may last longer — but most standard locks begin to wear or become outdated within this timeframe.
What is the best type of lock to upgrade to?
For most homes in London, we recommend anti-snap euro cylinders (3-star rated) or British Standard mortice locks for wooden doors. These provide a much higher level of protection compared to basic locks.
Can an old lock still work but be unsafe?
Yes — and this is very common. A lock may still turn and function, but internally it can be weak or vulnerable to modern break-in methods.
How long does it take to replace a lock?
Most standard lock replacements take 15–30 minutes, depending on the type of door and lock.
