When you need a security overhaul, you have a couple of options. Should you invest in a whole new set of locks? Or, should you opt for rekeying? Here at FA Locksmith in the Triangle Area, we know that it’s a decision that lots of homeowners, property managers, and business owners struggle with. And we want to help!
Here are some important differences between lock rekeying and replacement to help you make the best decision for your security needs!


Rekeying versus replacement: The basics
Lock replacement is a straightforward process. You remove the compromised lock and replace it with a new one. The most obvious benefit of this option is the chance to upgrade your security with a modern, brand-new lock. And, it can be useful if you’re interested in implementing a master key system (more on that later.)
But, what is rekeying? In a rekeying service, your locksmith will remove the cylinder of your existing lock and recalibrate the internal pins. This will mean that your lock will now open with a new set of keys, rendering the old set useless. This instantly restores your security if you fear that your keys have been copied or fallen into the wrong hands.


Drawbacks of replacement versus rekeying
When deciding between the two types of services, there are a few drawbacks you’ll want to be aware of.
Let’s start with lock replacement:
- The risk of installation issues. You may find that the new lock doesn’t fit snugly into the existing housing in the door. You’ll need to spend some extra time adjusting the housing for the dimensions of the new lock.
- Timing. There may be a gap in time between when you’ve experienced the security breach and when the new locks will be delivered.
- Getting rid of the old lock. If your locks are in good condition or you purchased them recently, it can feel like a waste of money and materials to replace them just because of a security set-back.
Rekeying also comes with a few potential drawbacks to be aware of, such as:
- Existing security vulnerabilities. Rekeying can restore your security but it won’t make your site more secure than before. If your locks are old, worn down, and ready for an upgrade, rekeying will only buy you a little more time before you have to replace your locks.
- Master key incompatibilities. If you’ve been thinking about installing a master key system at your business, a security overhaul could be the optimal time to do it. Unfortunately, if your locks come from different manufacturers, they may not be compatible for a master system, which means that you should opt for lock replacement instead of rekeying.
- Rekeying doesn’t fix damage. If someone has tried to force their way into your space, they may have damaged the lock in the process. If this is the case, the lock may need to be replaced instead of rekeyed.


Is rekeying or lock replacement more DIY-friendly?
Maybe you want to tackle this security breach yourself, and you’re wondering which option is more DIY-friendly.
On the one hand, lock replacement may be accessible to anyone with basic power tools and low to moderate security needs. Many deadbolts, cylinder locks, and even smart locks can be installed by people with some experience doing home improvement projects. Keep in mind, of course, that this may require cutting the appropriate housing into your door or installing a power source for some types of smart locks. And, if you’re working with a high security system, electrified lock, or other more complicated situation, your best bet is to call a locksmith.
On the other hand, rekeying is a job that is not DIY-accessible for most people. Rekeying requires you to disassemble the lock cylinder, reorder the pins and cut a new key.
What about interchangeable cores?
If you want to be able to immediately restore your security without waiting for a new lock or a locksmith, an interchangeable core system might be right for you. This will allow you to remove and replace the lock cylinder with one ready to go. Then, at your convenience, you can bring the compromised cylinder to your locksmith for rekeying. In this way, you always have a backup that you can rely on in the case of a security emergency.


More on master key systems
If you have a master key system in place, you may be wondering what your next steps are after your security has been compromised. Will you need to rekey the entire system? Is it possible to replace some of the locks and not others?
In many circumstances, a locksmith can rekey the particular level of security that’s been affected without having to replace keys at other levels. This may be a more convenient and cost-effective option than replacing the lock.
If, on the other hand, you’ve been thinking of implementing a master key system, this might be an opportunity to replace any locks that have been preventing you from doing so. In other words, now would be the time to replace any locks that aren’t compatible with the majority of your locks so that you can create a cohesive master key system. Implementing a master key system may involve rekeying some of your existing locks and replacing others so that they all fall under the new master key hierarchy.
