What Changing Locks After Moving Means
Changing locks after moving is a crucial security step that goes beyond simply swapping out hardware. It represents a comprehensive approach to protecting your new home and family from potential risks associated with previous key holders.
The primary purpose of changing locks involves completely eliminating the possibility that unknown individuals might still possess keys to your property. This includes previous homeowners, estate agents, maintenance workers, or anyone who might have had legitimate access before your ownership. Securing your home’s entry points means ensuring no unauthorised person can gain unexpected entry.
Key considerations for lock replacement include:
- Checking all external entry points including front and back doors
- Examining window locks and garage mechanisms
- Evaluating the current lock quality and potential upgrade opportunities
- Assessing potential vulnerabilities in your home’s security system
Beyond physical security, changing locks represents a psychological reset. It transforms a previously occupied space into your home, providing a sense of ownership and personal safety. This process symbolises a fresh start, marking the transition from one household to another.

Modern lock replacements also offer enhanced security features compared to older installations. Contemporary British Standard locks provide superior protection against picking, bumping, and forced entry techniques that older locks might be vulnerable to.
Pro tip: Schedule your lock replacement within the first week of moving to ensure immediate security and peace of mind.
Who Might Still Have Old Keys
Moving into a new home brings excitement, but it also introduces potential security vulnerabilities related to key circulation. Numerous individuals might still possess keys to your property, creating significant risks that many new homeowners overlook.
The range of potential key holders is surprisingly broad and includes:
- Previous homeowners and their family members
- Estate agents who managed the property sale
- Maintenance workers and contractors
- Former tenants and their associates
- Cleaners and housekeeping staff
- Neighbours who might have been given emergency access
- Friends or relatives of the previous occupants
Each of these groups represents a potential security breach. Untracked key copies can provide unexpected and potentially dangerous access to your home, often without your knowledge or consent. The psychological impact of knowing strangers might still have entry to your personal space can be unsettling.
Moreover, tracking down and collecting all existing keys is practically impossible. Key management becomes complex when a property has changed hands multiple times or been a rental property with frequent occupants. Professional locksmiths recommend a complete lock replacement to eliminate these uncertainties and restore your sense of security.
Here is a comparison highlighting when it is most advisable to change locks after property transactions:
| Scenario | Risk of Unauthorised Access | Recommended Timing |
|---|---|---|
| After buying from the previous owner | High, multiple key holders are likely | Immediately after move-in |
| After long-term rental | Moderate, former tenants may have keys | On tenant change or lease renewal |
| After major renovation | Elevated, contractors may retain access | Upon completion of works |
| After lost key incident | Significant, keys could be copied | As soon as possible |
Pro tip: Request a detailed key history from your estate agent during the property purchase to understand potential key distribution.
Home Insurance Rules And Key Risks
Home insurance policies often contain specific requirements regarding property security that many homeowners are unaware of. Insurance-approved locks play a critical role in maintaining valid coverage and protecting your financial investment.
Key insurance considerations related to home security include:
- Compliance with British Standard lock specifications
- Documented evidence of professional lock installations
- Regular security system maintenance
- Demonstrable efforts to minimise potential break-in risks
- Prompt reporting of security vulnerabilities
Insurance providers typically mandate specific security standards that directly impact your policy’s validity. Unmodified locks or those not meeting minimum security requirements can potentially invalidate your entire home insurance claim, leaving you financially exposed in the event of a burglary.
Moreover, insurers expect homeowners to take reasonable precautions. This means changing locks after moving is not just a recommended practice but often an explicit policy requirement. Failure to update locks, especially after property transfers or when multiple unknown parties might possess key copies, could be considered a breach of your insurance contract.

Pro tip: Request a written security assessment from your locksmith to provide documentation for your insurance provider.
Types Of Locks And Security Upgrades
Upgrading your home’s locks after moving is not just about replacing hardware, but strategically enhancing your property’s security. Lock types and security upgrades have evolved significantly, offering homeowners multiple layers of protection.
Key lock types for comprehensive home security include:
- 5-Lever Mortice Deadlocks: Traditional and robust, ideal for wooden doors
- Anti-Snap Euro Cylinders: Designed to prevent forced entry techniques
- Multi-Point Locking Systems: Distribute security across multiple lock points
- Smart Locks: Provide keyless entry and digital access tracking
- Bump-Resistant Cylinders: Prevent picking and manipulation attempts
British Standard BS3621 certification represents the gold standard for lock security, ensuring that your chosen locks meet rigorous professional criteria. These locks not only provide enhanced protection but also typically satisfy insurance requirements, giving you peace of mind.
Modern security upgrades go beyond traditional mechanical locks. Electronic and smart lock technologies now offer advanced features like remote access control, activity logs, and integration with home security systems. These innovations allow homeowners to monitor and manage their property’s security with unprecedented convenience and precision.
Below is a summary of common lock types and suitable door applications for new homeowners:
| Lock Type | Best For | Main Advantage |
|---|---|---|
| Mortice Deadlock | Wooden doors | Traditional, robust security |
| Euro Cylinder | uPVC/Composite doors | Anti-snap resistance options |
| Multi-Point System | External entrances | Evenly distributed locking points |
| Smart Lock | Any main entry door | Keyless, trackable access |
Pro tip: Consult a professional locksmith to assess your specific property’s security needs and recommend tailored lock solutions.
Choosing A Locksmith Versus DIY Lock Change
When securing your new home, the decision between hiring a professional locksmith and attempting a do-it-yourself lock change requires careful consideration. Professional locksmith services offer critical security expertise that goes far beyond simply replacing hardware.
Key differences between professional and DIY lock changes include:
- Precision Installation: Professional locksmiths ensure an exact fit
- Security Assessment: Expert evaluation of your property’s unique vulnerabilities
- Insurance Compliance: Guaranteed adherence to industry standards
- Advanced Product Knowledge: Recommendations for optimal lock systems
- Warranty and Guarantees: Professional workmanship with legal protection
Technical complexity makes lock replacement more challenging than many homeowners anticipate. While DIY approaches might seem cost-effective initially, incorrect installation can compromise your entire home’s security infrastructure. Professional locksmiths bring specialised tools, extensive training, and an understanding of current security technologies that most individuals cannot match.
Moreover, insurance companies often require documented professional installation. A locksmith provides certification and detailed records, which can be crucial if you need to make an insurance claim following a break-in. Their expertise extends beyond mere hardware replacement to a comprehensive security strategy.
Pro tip: Request written documentation of your lock installation to maintain compliance with home insurance requirements.
