Before diving into costs and deciding which option is better, it’s crucial to understand what rekeying and replacing a lock actually entail.
Rekeying a lock involves adjusting the internal components so that the old key no longer works and a new key is required to unlock it. A locksmith will replace the pins inside the lock cylinder to match a new key while keeping the exterior hardware intact. This is a preferred option when security needs change but the lock itself is still in good condition.
Replacing a lock, on the other hand, means removing the old hardware entirely and installing a completely new lockset. This might be necessary if the existing lock is outdated, damaged, or doesn’t provide the level of security desired.
Cost Comparison: Which Option Saves You More Money?
In most cases, rekeying is the more cost-effective solution. The process only requires the replacement of internal pins and a new key, making it a quicker and more affordable fix. The cost of rekeying a lock typically ranges from $15 to $50 per lock, depending on the locksmith’s fees and the type of lock involved. If you opt to do it yourself, rekeying kits can cost as little as $10 to $30.
Replacing a lock is generally more expensive because it involves purchasing an entirely new lockset. Basic locks can range from $20 to $150, and high-security smart locks can cost upwards of $300. Additionally, professional installation fees can add $50 to $200, depending on complexity.
Security Considerations: When Should You Rekey or Replace?
While cost is a significant factor, security should always be a primary concern. Rekeying is a great option if you want to maintain security while minimizing expenses. It’s commonly used when moving into a new home, after losing a key, or if a tenant moves out of a rental property.
However, replacing a lock may be the better choice if:
- The existing lock is outdated or worn out.
- You want to upgrade to a higher-security lock system.
- The lock has been tampered with or damaged.
- You’re switching to a smart lock or electronic system for keyless entry.
Durability and Longevity: Does Rekeying Extend the Life of Your Lock?
Rekeying can extend the life of your existing lock as long as it is still in good working condition. Since it only involves changing the internal pins, the hardware remains intact, allowing you to continue using it for years. However, if a lock is already showing signs of wear—such as sticking, difficulty turning, or rust—it may be more practical to invest in a replacement rather than rekeying it multiple times.
DIY vs. Professional Services: Which Option is More Affordable?
For those who are handy with tools, rekeying a lock can be a simple DIY project using a rekeying kit. Many popular lock brands, such as Kwikset and Schlage, offer easy-to-use kits that allow homeowners to change the keys themselves, saving on locksmith fees.
Replacing a lock, however, requires more expertise. If you choose to install a new lock yourself, you may save money, but improper installation can compromise security. A professional locksmith ensures that the lock is fitted correctly and offers recommendations on the best security options.
Risks Involved: Are There Hidden Costs in Rekeying or Replacing?
Both rekeying and replacing come with potential risks if not done correctly. Poorly rekeyed locks may result in malfunctions, while incorrect replacement can leave security vulnerabilities. Additionally, some high-security locks have patented key systems that cannot be rekeyed without specialized tools or manufacturer involvement, making replacement the only viable option.
Final Verdict: Which One Should You Choose?
If your goal is to enhance security at the lowest possible cost, rekeying is the better option. It allows you to maintain your existing locks while ensuring that old keys are rendered useless. However, if your locks are outdated, worn out, or you want to upgrade to a more advanced locking system, replacing is the more practical long-term investment.
Ultimately, the decision depends on your specific needs, budget, and security concerns. If your lock is still functional and secure, rekeying is the most cost-effective choice. But if you’re looking for an upgrade or dealing with a compromised lock, replacement is worth considering.
Conclusion
Both rekeying and replacing locks have their advantages, but rekeying generally offers the best balance between security and cost. However, when security is a top priority, and your lock is outdated or damaged, replacement is the better choice. By assessing your current lock condition, security needs, and budget, you can make an informed decision that ensures safety and peace of mind.
