When it comes to the security of your home or business, locks are your first line of defense. Over time, locks may become damaged, worn out, or compromised, and it’s important to know when to take action. One common dilemma that property owners face is whether to rekey their locks or replace them entirely. While both options have their benefits, understanding the cost and long-term advantages of each can help you make an informed decision.
In this article, we’ll explore the true cost of lock rekeying versus replacement, discussing the factors that influence the cost, the benefits of each option, and when to choose one over the other. Whether you’re a homeowner, business owner, or property manager in Kansas City, understanding these options can save you money while ensuring your property remains secure.
What is Lock Rekeying?
Lock rekeying is the process of changing the internal mechanism of a lock so that it works with a new key. Essentially, when you rekey a lock, the old keys will no longer open it, but the lock itself remains the same. This is typically done when you’ve lost your keys, moved into a new home, or need to prevent unauthorized access but don’t want to replace the entire lock.
Rekeying is an efficient way to maintain your existing lock hardware while ensuring that only the new key will work. The process involves a locksmith adjusting the pins or tumblers inside the lock to match a new key. It is a popular choice for those who want to change access without the added expense and hassle of installing a new lock.
What is Lock Replacement?
Lock replacement, on the other hand, involves removing the old lock entirely and installing a new one in its place. This option is usually considered when the existing lock is too damaged, outdated, or compromised to be effectively rekeyed. Lock replacement ensures that your property is secure with completely new hardware, and often, you’ll have the opportunity to upgrade to a more advanced or secure lock system.
Replacing a lock is typically more expensive than rekeying because it involves not only the cost of the new lock but also the labor required to remove the old one and install the new one. However, it provides the benefit of entirely new security hardware, which may be necessary for those who want enhanced security or a more modern locking system.
The Cost of Lock Rekeying
Lock rekeying is often the more affordable option, especially when compared to lock replacement. On average, rekeying a single lock can cost anywhere from $50 to $150, depending on the complexity of the lock and the locksmith’s rates. Rekeying is generally less expensive because it does not involve replacing the lock hardware. Instead, the locksmith simply adjusts the internal components of the existing lock to work with a new key.
If you have multiple locks in your home or business that need to be rekeyed, you may be able to save money by having them all rekeyed at once. Many locksmiths offer discounts for bulk rekeying services, so it’s worth asking about package deals if you need to secure several doors at the same time.
Rekeying is a cost-effective choice for those who are primarily concerned with changing access control without the need for an entirely new lock. It’s especially useful in situations like moving into a new home, losing keys, or wanting to restrict access to certain areas while maintaining the original lock hardware.
The Cost of Lock Replacement
The cost of lock replacement varies significantly depending on the type of lock, the brand, and the complexity of the installation. Basic residential locks typically range from $100 to $250 for both the lock and installation, while high-security or commercial locks can cost significantly more, ranging from $250 to $500 or more.
Labor costs for replacing a lock will also depend on factors like location and the complexity of the installation. A simple residential lock replacement might cost around $75 to $150 for labor, while more complex installations, such as electronic or smart locks, could cost more.
While lock replacement tends to be more expensive, it offers the advantage of completely new hardware and the opportunity to upgrade your security system. If you’ve experienced damage to your lock, your lock is outdated, or you simply want the peace of mind that comes with installing a new system, lock replacement might be the right choice.
When to Choose Rekeying
Rekeying is a great option for many situations, especially if your current locks are still in good condition. Some common scenarios where rekeying makes the most sense include:
- Moving into a new home: If you’ve just purchased a new property, rekeying all of the locks is an important step to ensure that no previous owners or tenants have access to the property.
- Lost keys: If your keys are lost or stolen, rekeying provides an affordable way to prevent unauthorized access without the need to replace the entire lock.
- Changing employees: In businesses where employees come and go, rekeying locks can help maintain security without having to replace every lock when a staff member leaves.
- Budget constraints: If you want to improve security on a budget, rekeying is a cost-effective solution compared to replacing locks.
Rekeying is also ideal if your locks are in relatively good condition and you do not need to upgrade to more secure or modern locking mechanisms.
When to Choose Lock Replacement
While rekeying is an affordable solution, there are situations where replacing the lock entirely is a better choice. Lock replacement may be necessary in cases such as:
- Damaged locks: If your locks are worn out, damaged, or malfunctioning, rekeying may not be effective. In these cases, it’s best to replace the lock entirely to ensure your security system is reliable.
- Upgrading security: If you want to enhance your security, replacing old locks with newer, more secure models—such as deadbolts, smart locks, or high-security locks—may be the best option.
- Outdated technology: If you’re still using old, traditional locks, replacing them with modern electronic or smart locks can provide enhanced security features and remote access.
- Frequent access changes: If you have a business with changing employees or tenants, lock replacement allows for a more robust solution, especially when you need to install high-security locks.
If your current locks are not meeting your security needs, replacing them can provide better protection and give you peace of mind.
