How Much Does It Cost to Re-Key a House?


When it comes to home security, one of the essential aspects is ensuring that your locks are secure and functioning properly. Re-keying your house is an important step to take, especially if you’ve recently moved into a new home or have concerns about the security of your existing locks. However, before diving into the process, it’s crucial to understand the costs associated with re-keying a house.

What is re-keying a house?


Re-keying refers to the process of changing the internal components of a lock cylinder so that it can be operated by a new key. It allows you to maintain the existing locks but renders any previously used keys ineffective.


The primary purpose of re-keying is to enhance security without the need to replace the entire lock. It provides homeowners with control over who has access to their property, offering peace of mind.

Factors affecting the cost

Various factors come into play when determining the cost of re-keying a house.

Type of locks

Different types of locks exist, ranging from basic pin tumbler locks to high-security locks. The complexity and sophistication of the lock mechanism can influence the cost of re-keying.

Number of locks

The total number of locks you need to re-key will affect the overall cost. Typically, the more locks you have, the higher the expense.


The accessibility of the locks also plays a role. If the locks are easily reachable and don’t require much effort to access, the cost may be lower compared to locks in hard-to-reach areas.

Average cost of re-keying

Cost per lock

On average, re-keying a lock can cost anywhere between $50 and $150 per lock. This cost includes the labor involved in disassembling and reassembling the lock, as well as creating new keys.

Additional charges

Additional charges may apply, such as service call fees or charges for replacing damaged parts. It’s essential to inquire about any potential extra costs when getting a quote.

DIY vs. Professional services

Pros and cons

While some homeowners may consider re-keying their locks themselves, it’s often recommended to hire professional locksmith services. Professionals have the necessary skills, experience, and tools to ensure the job is done correctly, minimizing the risk of any complications or damage.

Tips to save money

Request multiple quotes

To get the best deal, it’s wise to obtain quotes from different locksmiths. This allows you to compare prices and choose a service provider that offers a fair price without compromising on quality.

Negotiate for a better price

Don’t be afraid to negotiate with locksmiths. Some may be willing to adjust their prices or offer discounts, especially if you’re re-keying multiple locks.


Re-keying a house is an important step in maintaining home security. Understanding the cost factors associated with re-keying can help you make informed decisions and ensure you get the best value for your money.

In summary, the cost of re-keying a house depends on factors such as the type and number of locks, as well as the accessibility of those locks. On average, you can expect to pay between $50 and $150 per lock, including labor and new keys. It’s worth noting that additional charges may apply, so it’s essential to inquire about any potential extra costs.

While some homeowners may consider a DIY approach, it’s generally recommended to hire professional locksmith services. Professionals have the expertise and tools necessary to complete the job accurately and efficiently, minimizing any potential complications or damage.

If you’re looking to save money on re-keying, it’s advisable to request multiple quotes from different locksmiths. This allows you to compare prices and choose a service provider that offers a fair price without compromising quality. Additionally, don’t hesitate to negotiate with locksmiths as they may be open to adjusting their prices or offering discounts, especially if you have multiple locks to re-key.

In conclusion, re-keying your house is an investment in your home’s security. By understanding the factors that influence the cost and exploring options for saving money, you can ensure that your locks are secure and provide you with peace of mind.


Can I re-key my locks myself?

Can all types of locks be re-keyed?

Most traditional pin tumbler locks can be re-keyed. However, certain specialized locks, such as those with electronic components or unique keyways, may require replacement instead of re-keying.
