Factors Affecting Average Cost of Rekeying Locks
Several factors can influence how much you will pay to rekey your locks. Below are the key factors that impact the cost:
Factor 1: Number of Locks
The more locks you need to rekey, the higher the total cost will be. However, locksmiths may offer discounts for rekeying multiple locks at once, which can help reduce the overall cost. For instance, rekeying five locks may be cheaper per lock than rekeying just one or two due to reduced labor and travel time.
Factor 2: Complexity of Locks
Not all locks are created equal. Standard residential locks are easier and less expensive to rekey compared to high-security locks or smart locks. Complex locks with additional features such as electronic keypads or biometric access will cost more because they require specialized skills and tools to rekey.
Factor 3: Variation of Locks
If all of your locks are uniform (from the same brand and type), rekeying will generally be quicker and more straightforward, leading to lower costs. However, if you have multiple locks from different manufacturers, the locksmith may need to use various rekeying techniques or tools, which could increase the price.
Rekeying vs. Replacing Locks: Which is More Affordable?
Rekeying is almost always the more affordable option compared to replacing locks. When rekeying, a locksmith only changes the internal mechanism of the lock, allowing the old keys to be rendered useless while saving the lock hardware itself. This makes it a cost-effective solution when compared to lock replacement, which involves purchasing new locks and additional labor to install them.
Replacing locks is a better choice in situations where:
- The locks are outdated or damaged.
- You want to upgrade to a more secure or modern lock system.
- There are compatibility issues between the existing locks and your security needs.
For most situations, especially when moving into a new home or after losing a key, rekeying offers a practical, cost-efficient solution.
When Should You Consider Rekeying Your Locks?
There are several scenarios where rekeying your locks might be the best option:
- Moving into a New Home: Rekeying ensures that any old keys held by previous homeowners or contractors will no longer work.
- Lost Keys: If you’ve lost a set of keys, rekeying is a preventive measure to ensure that anyone who finds the keys cannot access your home.
- Increasing Home Security: Rekeying allows you to enhance your security without the added expense of replacing locks. You can also key multiple locks to work with a single key for convenience.
- Tenant Turnover in Rental Properties: Landlords often rekey locks between tenants to ensure security for the new occupants.
How to Find a Reliable Locksmith for Rekeying
Hiring a reliable locksmith is crucial when rekeying locks to ensure the job is done efficiently and securely. Here are some tips to find a trustworthy locksmith:
- Ask for Recommendations: Friends, family, or neighbors may have trusted locksmiths they can recommend.
- Check Online Reviews: Look for locksmiths with positive reviews and testimonials on platforms such as Google or Yelp.
- Verify Licenses and Certifications: Ensure the locksmith is licensed and certified to work in your area, which adds a layer of professionalism and reliability.
- Request an Estimate: Before hiring a locksmith, ask for an estimate of the cost to rekey your locks, including the service call fee and per-lock rate.
- Availability of Emergency Services: If you need immediate assistance, choose a locksmith who offers 24/7 emergency services.
Conclusion
Rekeying your locks is a cost-effective solution that provides security and peace of mind without the need to replace your entire lock system. The average cost to rekey locks ranges from $50 to $150, depending on factors such as the number of locks, their complexity, and whether they are high-security models.
