Hiring a Locksmith vs. Changing Locks Yourself

When you move into a new home, one of the most critical tasks to ensure your security is changing the locks. You have two main options: hiring a professional locksmith or doing it yourself. Each approach has its own set of advantages and disadvantages. For example, hiring a locksmith provides professional installation and access to high-quality products, ensuring optimal security. Conversely, changing locks yourself can save money and offer flexibility but carries the risk of improper installation and security vulnerabilities. This guide will help you understand the key differences, such as cost, convenience, and security, to make the best choice for your situation.

Benefits of Hiring a Locksmith

Expertise and Experience

Professional locksmiths have the knowledge and experience to recommend the best locks for your specific needs. They stay updated on the latest security technologies and provide solutions tailored to your home. For instance, a professional locksmith will know if your front door lock needs to meet British Standard BS3621 for insurance purposes or if anti-snap euro cylinders are necessary for added security. 

They can advise on high-security deadbolts for wooden doors or smart locks compatible with your existing smart home system. By understanding local security challenges and specific types of door locks, locksmiths ensure optimal protection and compliance with relevant security standards.

Proper Installation

Locksmiths ensure that locks are installed correctly, which is crucial for optimal security.  Improperly installed locks can be easily tampered with, compromising your home’s safety. A professional will make sure the lock is fitted precisely, whether it’s a deadbolt, mortise lock, or smart lock. They will ensure alignment with the door frame, correct placement of strike plates, and proper tightening of screws to prevent lock misalignment or loosening over time. This reduces the risk of lock fitting mistakes that could otherwise leave your home vulnerable to break-ins and increases the overall reliability of your home security.

Time and Convenience

Hiring a locksmith saves you time and effort. They can complete the job quickly and efficiently, allowing you to focus on other aspects of moving into your new home. Whether you need to change locks on the front door, multiple doors, or even install a complex security system, a professional locksmith can handle the task seamlessly. For example, if you require rekeying for all the locks in your home, a locksmith can perform this task swiftly, ensuring that all keys match and work properly without you having to juggle multiple sets of keys or struggle with unfamiliar tools.

Access to Quality Products

Locksmiths have access to high-quality locks and security systems that may not be available to the general public. They can provide options that meet industry standards and offer enhanced security features. Additionally, locksmiths can source high-security locks like anti-snap, anti-bump, and anti-pick euro cylinders from reputable brands such as Yale, Chubb, and Mul-T-Lock. These advanced products are rigorously tested to withstand various attack methods, ensuring your home remains secure against potential intruders.

Guaranteed Work

Many professional locksmiths offer warranties on their work and the products they install. This provides peace of mind knowing that if any issues arise, they will be addressed promptly and professionally. For instance, if a newly installed smart lock malfunctions or a high-security deadbolt shows defects, the locksmith will repair or replace it at no extra cost. This guarantee is particularly valuable when investing in high-security locks or advanced locking systems, ensuring your home remains secure and your investment protected.

Hiring a Locksmith Disadvantages 


Hiring a locksmith can be more expensive than changing locks yourself. The cost includes labour fees and the price of the locks, which can add up, especially if you need to change multiple locks. Understanding how much a locksmith costs is important for budgeting your home security upgrades.


You may need to schedule an appointment, which can be inconvenient if you need the locks changed immediately. However, many locksmiths offer emergency services for urgent situations, providing flexibility when you need immediate lock replacement.

Changing Locks Yourself Advantages

Cost Savings

One of the main reasons homeowners opt to change locks themselves is to save money. By purchasing the locks and installing them on your own, you can avoid labour fees. This approach can be particularly beneficial if you’re on a tight budget and need to replace locks on multiple doors.


DIY lock changing allows you to work at your own pace and on your own schedule. This can be particularly beneficial if you’re handling multiple tasks during your move. You can choose the best time to replace the lock without waiting for a locksmith’s availability.

Learning Experience

Changing locks yourself can be a valuable learning experience. Understanding how locks work and how to install them can be empowering and useful for future home maintenance. It provides a sense of accomplishment and self-reliance.

Changing Locks Yourself Disadvantages

Risk of Improper Installation

Without proper training, there’s a risk of installing the locks incorrectly. DIY lock replacement can lead to security vulnerabilities, making it easier for intruders to break in. Mistakes during lock fitting can compromise the integrity of the lock and door.

Limited Product Knowledge

As a DIYer, you might not have access to or knowledge of the best lock products and security features. This could result in choosing less secure or incompatible locks for your doors. Professional locksmiths can recommend the most effective products for your specific needs.

Time and Effort

Changing locks yourself can be time-consuming and physically demanding, especially if you’re unfamiliar with the process. It might also require tools that you don’t readily have on hand. This can add to the overall effort and complexity of the task.

No Warranty

DIY lock replacement installations usually don’t come with a warranty. If the locks fail or are installed improperly, you’ll be responsible for any additional costs to fix or replace them. This lack of a safety net can be a significant drawback compared to hiring a professional.

Should I Hire a Locksmith or Change the Locks Myself?

For homeowners who prioritise security and convenience, hiring a professional locksmith is often the best choice. Professional locksmiths provide expert advice, proper installation, and access to high-quality products, ensuring your home is secure. Additionally, the benefits of hiring a locksmith, such as time savings, guaranteed work, and enhanced security features, often outweigh the cost.

However, if you have the skills and confidence to do it yourself, and you’re looking to save on costs, changing the locks on your own can be a viable option. Just be aware of the risks of DIY lock replacement, including the potential for improper installation, and lack of warranty. Regardless of your choice, ensuring that your new home is secure should always be the top priority.
