Should I Change Locks After Moving House?

Moving into a new home is exciting, but one important security step is often overlooked — changing the locks. Many homeowners assume the keys handed over during the move are the only copies in circulation, but in reality, there’s no way to know how many duplicate keys may still exist.

At Chelmsford Locksmith, we regularly help homeowners across Chelmsford improve their security after moving house with professional lock replacement and lock upgrade services.

Is It Necessary to Change Locks After Moving?

In most cases, yes. Changing your locks after moving house is strongly recommended for security and peace of mind.

Previous key holders may include:

• Former owners
• Tenants
• Estate agents
• Builders or contractors
• Cleaners
• Neighbours
• Dog walkers or pet sitters
• Family members of previous occupants

Even if the previous owner returns all visible keys, you cannot be certain extra copies were never made.

Improve Your Home Security Immediately

Changing locks is one of the quickest ways to secure your new property from day one.

Benefits include:

• Full control over property access
• Peace of mind for your family
• Improved burglary protection
• Removal of unknown key access
• Opportunity to upgrade older locks

This is especially important if the property has older or worn locking systems.

Upgrade to Modern Anti-Snap Locks

Many older homes still use outdated euro cylinder locks that may be vulnerable to lock snapping — one of the most common burglary methods in the UK.

A locksmith can upgrade your property with:

• Anti-snap locks
• High-security cylinders
• British Standard locks
• Smart lock systems
• Reinforced door security

Modern lock upgrades can significantly improve overall home protection.

Popular security brands include:

• Yale
• Ultion
• ERA

When Should You Change Locks After Moving?

Ideally, locks should be changed as soon as possible after collecting the keys.

Many homeowners arrange lock changes:

• On moving day
• Within the first week
• Before fully moving valuables into the property

The earlier you secure the home, the lower the risk of unauthorised access.

Should You Replace Every Lock?

Not always — but it depends on the property and your security concerns.

A locksmith can assess:

• Front and back door locks
• Patio and French doors
• Garage access points
• Window locks
• UPVC door mechanisms

In some cases, replacing only the cylinders is enough. In others, full lock replacement or upgrades may be recommended.

What About UPVC Door Locks?

UPVC doors are common in UK homes, but older mechanisms can wear out over time.

Signs of problems include:

• Stiff locks
• Misaligned doors
• Loose handles
• Difficulty turning keys
• Failed locking mechanisms

If you have recently moved into a property with UPVC doors, it may be worth having them inspected by a locksmith.

Can a Locksmith Rekey Locks Instead?

In some situations, rekeying may be possible instead of full replacement. Rekeying changes the internal lock configuration so old keys no longer work.

This can be:

• More cost-effective
• Faster than replacing entire locks
• Suitable for certain lock types

A locksmith can advise on the best option for your property.

Home Insurance and Lock Security

Some home insurance providers require certain security standards, especially for external doors.

Upgrading locks after moving house can help:

• Improve compliance with insurance requirements
• Reduce security risks
• Protect against future claims issues

British Standard approved locks are commonly recommended.
