When to Change Your Locks and Why It’s Crucial for Your Safety

Many homeowners and tenants in London rarely think about their door locks—until something goes wrong. Yet your locks are the first line of defence between your property and potential intruders.

Knowing when to change your locks can significantly reduce your vulnerability and give you peace of mind, whether you live in a flat in Hackney, a townhouse in Chelsea, or a semi-detached home in Enfield.

In this article, Locksmith CO explains the most important times to change your locks and why it’s not just a smart decision—it’s a crucial one for your personal and property security.

After Moving into a New Home or Flat

One of the first things you should do after moving into a new property—whether you’ve bought it or are renting—is to replace the locks.

Why? Because you cannot be certain how many copies of the keys exist or who still has access. Previous owners, tenants, estate agents, contractors, or even neighbours may have spare keys.

By changing the locks immediately, you:

• Regain exclusive control over your home
• Prevent unauthorised access
• Ensure your insurance policy remains valid

Locksmith CO provides same-day lock changes for new homeowners, tenants, and landlords throughout London.

After a Break-In or Attempted Burglary

If your property has been broken into or targeted in an attempted burglary, it’s vital to change your locks right away. Even if the burglar didn’t gain entry, they may have:

• Damaged the lock mechanism
• Picked or bypassed the existing lock
• Taken keys or found hidden spares

In such situations, we also recommend upgrading to British Standard BS3621 locks, which are more resistant to picking, drilling, and forced entry. Locksmith CO offers fast post-burglary lock replacement and door reinforcement services across all London boroughs.

When Your Keys Have Been Lost or Stolen

Losing your keys isn’t just an inconvenience—it’s a serious security risk. Whether they’re dropped on the street, forgotten in a public place, or taken by someone with bad intentions, your home is now exposed to unauthorised access.

Why changing the locks is essential:

• You don’t know who found or took the keys
• Copies may be made without your knowledge
• Waiting too long gives potential intruders more opportunity

Locksmith CO can change your locks or rekey your existing lock mechanisms to ensure that old keys no longer work. We also offer smart lock upgrades for keyless access control.

After a Relationship Breakdown or Dispute

Going through a break-up, separation, or dispute with a family member, flatmate, or partner can be emotionally difficult—and it may also raise concerns about your safety and privacy.

Even if keys are returned, there’s no guarantee that duplicates weren’t made. In these circumstances, it’s wise to change your locks immediately to protect yourself, your belongings, and your peace of mind.

At Locksmith CO, we offer discreet and fast lock changes for individuals dealing with sensitive personal situations in London.

If You’ve Given Out Spare Keys in the Past

Over the years, many people lend keys to:

• Cleaners or contractors
• Neighbours or friends
• Airbnb guests or short-term tenants

Tradespeople or ex-employees (for commercial properties)

Unless you’ve kept strict track of every spare key and had them returned, it’s impossible to be sure who still has access to your home or business. If you’re unsure—or have concerns about potential misuse—replacing the locks is the safest solution.

When the Lock Is Damaged or Malfunctioning

Locks, like any mechanical device, wear down over time. Signs of damage or wear include:

• Keys sticking or jamming in the lock
• Difficulty turning the key
• Loose or wobbly handles
• Doors that don’t fully close or latch

These issues may not seem urgent at first but can quickly lead to lockouts or total lock failure—sometimes at the worst possible moment. A failing lock is not only inconvenient but also a security liability.

Changing your lock at the first sign of malfunction ensures smooth access and protection. Locksmith CO’s technicians can inspect your current hardware and advise if repair or full replacement is needed.

If Your Lock Doesn’t Meet British Standards

Many older locks installed in London homes—especially uPVC or wooden doors—do not meet current security standards required by most insurance companies.

The most widely accepted certification is BS3621, which is recognised by police and insurers for its anti-drill, anti-pick, and anti-bump features.

Changing to British Standard-approved locks improves both security and compliance with your home insurance policy. Locksmith CO supplies and installs BS3621 mortice and cylinder locks throughout the city.

When Upgrading to Smart Locks or Keyless Entry

If you’re looking to modernise your home or simplify access, upgrading to a smart lock is an excellent reason to change your existing locks. Smart locks offer:

• Keyless entry with PIN codes, fobs, or smartphones
• Remote access and control via mobile apps
• Integration with home security systems
• Custom access for family, guests, or service providers

Locksmith CO installs and supports a wide range of smart locks in London, suitable for homes, flats, and rental properties.

For Business or Commercial Property Security

Lock changes aren’t just for residential properties. Businesses in London should also consider changing locks:

• After employee turnover or dismissal
• Following attempted break-ins or vandalism
• If key control has been compromised
• During renovations or access restructuring

We offer commercial locksmith services including high-security locks, master key systems, and access control solutions tailored for offices, shops, warehouses, and shared spaces.

How Often Should You Change Your Locks?

While there’s no fixed rule, security experts recommend evaluating your locks every 5 to 7 years, or immediately after any event that compromises access or trust.

Changing your locks is not just a reactive step—it’s a proactive investment in your personal safety. Locksmith CO is here to help you take that step confidently.
