Moving into a new home is exciting, but amid the unpacking and decorating, one critical security task should be your top priority: changing the locks. You cannot know who has copies of the existing keys, previous owners, tenants, cleaners, tradespeople or neighbours may all possess duplicates. Changing your locks immediately ensures that only you and your trusted family members have access.
Why Changing Locks Is Essential
Even if the previous owners handed over all their keys, there is no guarantee that copies were not made. Estate agents, landlords, maintenance workers and even friends of previous occupants may have had access. The risk is not theoretical, it is a known factor in many burglaries where former keys are used to gain easy entry.
Changing locks is also an opportunity to upgrade security. The existing locks may be outdated, worn or non-compliant with insurance requirements. Moving home provides the perfect moment to bring your security up to modern standards.
Which Locks to Change
Prioritise the following locks when moving into a new property:
- Front door: The primary entry point must be secured with a new high-security lock
- Back door: Often targeted by burglars who prefer hidden rear access
- Patio or French doors: Frequently fitted with basic locks that are easily compromised
- Garage door: If attached to the house, this provides direct internal access
- Window locks: Ground-floor and accessible windows should have key-operated locks
- Shed and outbuildings: These often contain tools that could be used to break into the main house
Choosing New Locks
When selecting replacement locks, consider:
- British Standard BS3621: Required by most insurers for final exit doors
- Anti-snap cylinders: Essential for UPVC and composite doors
- Smart locks: Ideal if you want keyless entry and remote access control
- Master key systems: Useful for landlords or those managing multiple properties
Professional vs DIY
While changing a simple cylinder might be a DIY project, professional installation ensures correct fitting, security compliance and warranty protection. A locksmith can also identify and address door alignment issues, recommend upgrades you might not have considered, and provide documentation for your insurance provider.
