What Is the Difference Between Rekeying and Changing Locks
When it comes to home or business security, ensuring your locks are in top condition is crucial. However, many property owners struggle to decide whether they should rekey their locks or replace them entirely. Understanding the difference between rekeying and changing locks can help you make the best decision for your security needs while also considering cost, convenience, and effectiveness.
Understanding Rekeying
Rekeying locks is a process in which a locksmith changes the internal mechanism of the lock so that it can work with a new key. This is done by altering the lock’s pins and springs inside the cylinder. While the external appearance of the lock remains the same, the old key will no longer function.
When Should You Consider Rekeying?
Lost or Stolen Keys: If you lose your keys or suspect they may have been stolen, rekeying your locks ensures that the old keys no longer provide access to your property.
Moving into a New Home: When moving into a new residence, rekeying is a cost-effective way to ensure that previous owners, tenants, or contractors no longer have access.
Tenant or Employee Turnover: If a tenant or employee leaves and you want to prevent unauthorized access without replacing all the locks, rekeying is a quick and effective solution.
Master Key Systems: Rekeying is commonly used when setting up a master key system, allowing different levels of access while maintaining control over security.
Advantages of Rekeying
Cost-Effective: Rekeying is usually cheaper than replacing the entire lock since only the internal components need adjustment.
Quick and Convenient: A professional locksmith can rekey locks quickly, minimizing downtime or inconvenience.
Enhanced Security: If you suspect someone has an unauthorized key, rekeying immediately revokes their access.
Customization: Rekeying allows for keying multiple locks to work with the same key, simplifying key management.
Understanding Changing Locks
Changing locks involves completely removing the existing lock and replacing it with a brand-new one. This process requires selecting a new lockset and installing it, which may include modifications to the door.
When Should You Consider Changing Locks?
Damaged or Worn-Out Locks: If your lock is broken, rusted, or malfunctioning, replacing it is the best option for maintaining security.
Upgrading Security: If you want to switch to high-security locks, smart locks, or keyless entry systems, a lock replacement is necessary.
Changing Aesthetic or Functionality: When remodeling or upgrading your home’s appearance, replacing outdated locks with modern designs can enhance curb appeal and functionality.
Compromised Security: If your property has experienced a break-in or attempted burglary, replacing the locks ensures the compromised lock is no longer a weak point.
Advantages of Changing Locks
Increased Security Options: New locks come with advanced features like smart technology, keypad entry, and anti-pick mechanisms.
Full Customization: You can choose locks that match your specific security needs and preferences.
Better Aesthetic Appeal: Upgrading to stylish and modern locks can enhance your property’s look.
Durability and Reliability: New locks often provide better longevity, especially if upgrading to high-security models.
Key Differences Between Rekeying and Changing Locks
Cost: Rekeying is usually the cheaper option, while replacing locks requires purchasing new hardware.
Time Required: Rekeying is quicker and can often be done within minutes, while lock replacement may take longer, especially if additional modifications are needed.
Security Level: Changing locks provides an opportunity to upgrade to a higher security lock, whereas rekeying maintains the existing lock’s security level but with a new key.
Appearance: Rekeying keeps the same lock design, while replacing allows you to switch to a new style or finish.
Key Convenience: Rekeying allows multiple locks to work with a single key, while replacing locks may require multiple new keys.
Which Option Is Right for You?
The choice between rekeying and changing locks depends on your specific needs:
Choose Rekeying if you are happy with your existing locks but need to change access control for security reasons.
Choose Changing Locks if your current locks are outdated, damaged, or if you want an upgrade in security features.
