Moving into a new home is exciting, but it also comes with an important security question that many Wilmington and Leland homeowners overlook: what should you do about the existing locks? You don’t know how many keys are out there or who might have copies. Maybe the previous owners gave keys to neighbors, dog walkers, or contractors. Perhaps a key was lost years ago and never accounted for. This uncertainty is exactly why locksmiths like us get calls from concerned homeowners asking whether they should rekey or replace their locks.
The short answer? It depends on your specific situation, and I’ll walk you through how to make that decision.
What Does Rekeying Actually Mean?
Let’s start with the basics. Rekeying is the process of changing the internal pins inside your existing lock cylinder so that your old keys no longer work. A new key is cut to match the new pin configuration. The lock itself stays in place—same deadbolt, same doorknob, same everything on the outside. We’re just changing what’s happening inside the mechanism.
Think of it like changing the password to your email account. The account is the same, but the way you access it is different. That’s rekeying in a nutshell.
When Rekeying Makes Perfect Sense
Most of the time, rekeying is the smarter choice for Wilmington and Leland homeowners. Here’s when we typically recommend it:
You’ve just bought a house and the locks are in good shape. The previous owners might have quality Schlage or Kwikset locks that work smoothly. There’s no reason to rip them out and start over. We can rekey them in about 15-20 minutes per lock, and suddenly you’re the only one with keys that work.
Someone lost a key and you’re worried about who might find it. Maybe your teenager lost their house key at school, or your purse was stolen with your keys inside. Rekeying gives you peace of mind that whoever has that key can’t use it anymore.
You want all your doors to work with one key. This is something homeowners love. Instead of fumbling with three different keys for your front door, back door, and garage entry, we can rekey everything to match. One key for everything—it’s simple and convenient.
A roommate or tenant moved out. Even if you trust them, you don’t know if they made copies or who they might have given keys to. Rekeying ensures clean separation.
Rekeying compatible locks can cost less than replacing the hardware. For a home in Wilmington or Leland, ask for a job-specific estimate based on the number of locks, their condition and the parts required.
When You Should Replace Instead
Now, there are definitely situations where replacement is the better option:
The locks are old and worn out. If your deadbolt is sticky, the key is hard to turn, or the mechanism feels loose, those are signs of internal wear. You could rekey it, sure, but you’re just putting new pins in a tired lock. It might only last another year before problems start. Better to replace it with new hardware that’ll give you another decade or two of smooth operation.
You’re dealing with damage from a break-in attempt. If someone tried to force your lock or drill it out, the cylinder is compromised. The lock might still technically work, but its integrity is shot. Replace it.
You want to upgrade your security. Maybe you’re moving from a basic doorknob lock to a proper deadbolt. Or you want to step up from builder-grade locks to high-security options. Rekeying doesn’t change the level of security—replacement does.
The locks are different brands and you want consistency. If your front door has a Schlage, your back door has a Kwikset, and your side door has some off-brand lock from a hardware store, rekeying them all to one key gets complicated. Sometimes it’s easier to replace them all with matching locks.
You’re thinking about smart locks. Keyless entry is one option to discuss when planning a lock upgrade. If you’re going smart, you’re replacing the whole system anyway.
Assessing the Locks in Your Home
In a newer home, compatible locks in good condition may be suitable for rekeying when the property changes hands. Inspect their condition before deciding whether to keep the existing hardware.
Older homes may have locks that have been in service for many years. Some still work well and can be rekeyed; worn or damaged hardware may need replacement.
One common mistake we see is homeowners who rekey their front door but forget about the back door, garage entry, or side door. Every door that opens from the outside needs attention. We’ve literally had situations where someone rekeyed their front door for security after a break-in, but the burglar came back and used the unchanged back door.
The Master Key Option
Here’s something many homeowners don’t know about: you can set up a master key system even in a residential setting. Let’s say you have a home office or a storage room you want to restrict. We can rekey your locks so that certain keys only open certain doors, while your master key opens everything.
This is really useful for homeowners who rent out a room or have an in-law suite. The tenant gets a key to their space and the common areas, but can’t access your private spaces. You have a master key that works everywhere.
How to Decide: Ask Yourself These Questions
Are your locks less than 10 years old and working smoothly? Lean toward rekeying.
Has there been a security incident or attempted break-in? Replace.
Do you just need to control who has access? Rekey is fine.
Are you trying to upgrade your home’s security level? Replace.
Is the lock mechanism visibly damaged, rusted, or sticky? Replace.
Do you want to standardize all doors to one key? Rekey if locks are same brand, consider replacing if they’re all different brands.
The Bottom Line
For most Wilmington and Leland homeowners in most situations, rekeying is the practical choice. It’s faster, cheaper, and solves the security concern of unknown key copies. We can typically rekey all the locks in an average home in under an hour, and you’re done.
But if your locks are old, damaged, or you want to genuinely improve your security, don’t throw good money after bad. Invest in quality replacement locks that’ll protect your home properly.
