A locksmith is one of the oldest professions around, covering a range of skills, but that doesn’t mean you can’t pick up a trick or two. If you’re looking for a cost-effective way to improve your home security, rekeying or changing your locks yourself can be a practical option. Rekeying is generally cheaper than replacing an entire lock because it only requires adjusting the internal pins of the existing lock to fit a new key. While hiring a locksmith typically costs between R250 and R500 per lock for rekeying, a DIY approach can save on labor fees. However, you’ll need to invest in a rekeying kit or specific tools to do the job yourself.
Changing a lock, on the other hand, involves removing the old lock and installing a new one. This process is slightly more involved but still manageable for homeowners with basic tools and a bit of patience. If done professionally, lock changes usually cost between R350 and R800. Taking the DIY approach allows you to save on these labor fees while still upgrading your home’s security.
Tools and Tips for Rekeying
If you’re planning to rekey a lock yourself, having the right tools is essential. A rekeying kit is your most important purchase. These kits typically come with new pins, springs, and step-by-step instructions tailored to specific lock brands. In addition to the rekeying kit, you’ll need a Phillips screwdriver and pliers to disassemble and reassemble the lock. A flashlight can be useful for better visibility, especially if you’re working in dim lighting.
If you plan to rekey multiple locks, it may be worth investing in a professional-grade pinning kit. These kits offer a more comprehensive range of pins and springs to handle different lock types. However, they are significantly more expensive, often costing around R4,000 or more. For one or two locks, a standard rekeying kit is usually sufficient and more cost-effective.
Attention to detail is vital during the rekeying process. If you don’t have the original key, the task becomes more challenging, as you’ll need additional tools to access and reset the lock. Mistakes, such as damaging or misaligning the pins, can render the lock unusable, forcing you to buy a replacement. To avoid this, take your time and follow the instructions carefully.
Can You Rekey or Change Locks Yourself?
Yes, most homeowners can rekey or change locks themselves if they have the right tools and a bit of patience. Changing a lock is usually more straightforward, as it only requires basic tools like a screwdriver. You simply remove the old lock, follow the manufacturer’s instructions for the new one, and secure it properly. The whole process can be done within an hour. However, if you’re dealing with high-security locks or are unsure of the steps, hiring a locksmith may be the best option to ensure everything is installed correctly.
Rekeying locks is also possible as a DIY project, but it requires more precision. The process involves opening up the lock, replacing the internal pins with new ones that correspond to a new key, and then carefully reassembling the lock. This requires attention to detail and patience, as mistakes can leave the lock inoperable. If you’re not confident in your ability to handle the task, consider calling a locksmith. Their expertise can prevent costly errors and ensure your lock remains secure.
DIY vs. Professional Assistance
Deciding whether to rekey or change locks yourself or hire a locksmith depends on the complexity of the job and your comfort with handling lock mechanisms. DIY lock rekeying requires precision and a steady hand, especially when inserting and aligning small pins. Mistakes can damage the lock and end up costing you more than the price of a locksmith.
Changing a lock is a simpler process that requires fewer technical skills. With a screwdriver and clear instructions, most homeowners can swap out an old lock for a new one. However, improper installation can leave your lock misaligned, compromising its security and making it harder to operate.
For high-security locks or more complex systems, hiring a locksmith is often the better choice. Professionals can ensure proper installation, avoid errors, and address unexpected issues that might arise during the process. They have the tools and experience to handle even the most intricate locking systems, giving you added peace of mind.
Ultimately, the choice between DIY and professional assistance depends on your confidence, the tools at your disposal, and the type of lock you’re working with. Both methods offer a way to improve security, but professional help is a good fallback if you encounter challenges along the way.
Process and Practical Considerations for Rekeying Locks
The time it takes to rekey a lock depends on the type of lock and the person performing the task. For professional locksmiths, the process is relatively quick, typically taking between 10 to 40 minutes. Simpler locks can be rekeyed in as little as 15 minutes, while more complex locking systems may require 30 minutes or longer. For those attempting a DIY rekeying, the time frame is usually longer, especially if you’re unfamiliar with the process or lack the proper tools. The most time-consuming part is often removing the lock from the door, as the actual rekeying process is fairly quick once the lock is accessible.
Before starting, it’s important to determine whether your lock is suitable for rekeying. Most pin-tumbler locks can be rekeyed, provided they are in good working condition. If your lock opens and closes smoothly, it is likely a good candidate for rekeying. This option is ideal if you’ve misplaced a key or need to boost security without purchasing a new lock. However, locks that are excessively worn, damaged, or incompatible with rekeying (like certain electronic locks) may need to be replaced. If you’re unsure about your lock’s suitability, a locksmith can provide a professional assessment and advise on the best course of action.
It is possible to rekey a lock without the original key, but the process is more challenging. This approach, often referred to as “blind rekeying,” involves disassembling the lock to access the internal pins. Without the guidance of the original key, you’ll need to manually identify and adjust the pin configurations. While this is possible as a DIY project, it requires patience, precision, and the right tools. Professional locksmiths are better equipped to handle blind rekeying, as their tools and experience minimize the risk of mistakes or damage.
By considering factors like time, the lock’s condition, and whether you have the original key, you can make an informed decision on whether to attempt a DIY rekey or hire a professional locksmith.
Risks and Tools for Rekeying Locks
While rekeying a lock is a cost-effective way to improve home security, it’s not without risks. The most common problem is accidental damage to the lock. If the lock is already worn or damaged, attempting to rekey it could worsen the problem, potentially causing the lock to fail. Misaligned pins or springs are another common issue, as these components must be placed with precision. Misalignment can result in a lock that is stiff, difficult to turn, or entirely non-functional. In some cases, a misstep during rekeying could leave you locked out of your home or force you to replace the lock completely—an outcome that is far more costly than rekeying alone.
Another significant risk relates to key security. If you fail to control access to your new keys or forget to rekey the locks after moving into a new property, previous occupants, contractors, or even maintenance workers with old keys could still gain entry. This is why rekeying is one of the first steps homeowners are advised to take after moving into a new residence. If you’re rekeying on your own, it’s crucial to store the new keys safely and ensure that every pin and spring is properly aligned, as misalignment can compromise the lock’s security.
Locksmiths reduce these risks by using specialized tools that help them rekey locks efficiently and accurately. The most essential tool is a rekeying kit, which includes an assortment of pins, springs, and keys for specific lock brands and models. Other essential locksmith tools include:
– Plug followers: Used to keep pins in place as the lock cylinder is removed.
– Tension wrenches: Help maintain pressure on the lock cylinder to prevent pins from slipping.
– Pick tools: Small tools used to manipulate pins with precision.
– Screwdrivers: Essential for removing and reassembling lock components.
High-end rekeying kits also include specialty tools designed to streamline the process and minimize human error. With these tools, locksmiths can rekey locks quickly and precisely, reducing the risk of damage or misalignment.
If you’re planning to rekey locks on your own, you’ll need to invest in some of these tools. For basic jobs, a standard rekeying kit should suffice. However, more advanced locks or multiple rekeys may require higher-grade tools. For those unsure of their skills, hiring a professional locksmith is often the better option (with have a separate post for a breakdown of costs for replacing locks and other services charges). It minimizes the risk of costly mistakes, ensures that your home remains secure, and prevents you from accidentally rendering the lock unusable.
