As professional locksmiths, we see the consequences of inadequate home security every day. We attend burglaries, forced entries and lockouts that could have been prevented with the right precautions. This guide distils our expertise into practical, actionable advice to help you make your home as secure as possible.

Start with Your Locks

Your locks are your first line of defence. At minimum, all external doors should have a BS3621 approved 5-lever mortice deadlock or a high-security euro cylinder. If you have UPVC doors, ensure the cylinder is anti-snap rated — lock snapping is the most common burglary technique in the UK.

Check all your locks regularly. A lock that's stiff, difficult to operate or showing signs of wear should be replaced. A failing lock is an invitation to burglars.

Secure All Entry Points

Don't just focus on the front door. Burglars will try any entry point that looks vulnerable:

Back doors: Often less secure than front doors — ensure they have quality locks
Windows: Fit window locks on all ground floor and accessible windows
Patio doors: Fit anti-lift devices and a secondary lock or security bar
Garage doors: Ensure the garage door has a quality lock and any internal connecting door is secured
Garden gates: Fit a padlock or bolt to prevent easy access to the rear of the property

Lighting as a Deterrent

Burglars prefer to work in darkness. Good lighting around your property is one of the most cost-effective security measures you can take. Install motion-activated floodlights at the front and rear of your property. Use timer switches on indoor lights when you're away to create the impression that someone is home.

CCTV and Alarm Systems

Visible CCTV cameras and alarm systems are powerful deterrents. Research shows that properties with visible security systems are significantly less likely to be targeted. Keys4U installs CCTV systems and burglar alarms across the UK — from basic systems to fully monitored solutions.

Security Habits That Make a Difference

Always lock your door when you leave — even for a few minutes
Never leave a key in the lock on the inside of the door
Don't leave spare keys under doormats, plant pots or in other obvious places
Cancel milk and newspaper deliveries when you go on holiday
Ask a trusted neighbour to keep an eye on your property
Don't advertise holidays on social media
Mark valuable items with your postcode using a UV pen
Keep ladders and tools locked away — don't give burglars the tools to break in

Get a Professional Security Survey

The best way to identify vulnerabilities in your home security is to have a professional security survey carried out. A Keys4U locksmith will assess every entry point, identify weaknesses and recommend cost-effective improvements. Our security surveys are available across the UK.
