Buying a new home is an exciting milestone. Whether it’s your first house or you’ve recently relocated within Dover, NJ, there are countless tasks competing for your attention—unpacking boxes, setting up utilities, updating your address, and making the space feel like home.
Amid all the excitement, one critical task is often overlooked: securing your property by changing or rekeying the locks.
Many homeowners assume that receiving the keys at closing means they’re the only people with access to the property. Unfortunately, that’s not always the case. Previous owners may have shared spare keys with family members, neighbors, contractors, cleaners, or real estate agents. Without changing or rekeying the locks, you simply can’t know how many working copies are still out there.
If you want complete control over who can enter your home, updating your locks should be one of the first items on your moving checklist.
Your New Home Security Checklist
Before settling into your new house, make sure you’ve completed these important security tasks.
✔ Rekey or replace all exterior door locks.
✔ Test every lock to ensure it operates smoothly.
✔ Check that every window locks securely.
✔ Inspect garage and side entrances.
✔ Replace damaged or worn-out deadbolts.
✔ Confirm that only your household has working keys.
Completing these simple steps can significantly improve your home’s security from day one.
Why the Existing Keys May Not Be the Only Ones
Even if the previous homeowner hands over every key they own, there is no guarantee additional copies don’t exist.
Extra keys are commonly shared with:
Family Members
Parents, siblings, or relatives may still have spare keys from years ago.
Trusted Neighbors
Many homeowners leave emergency keys with neighbors while they’re away on vacation.
Contractors
Painters, plumbers, electricians, and remodeling companies often receive temporary access during renovation projects.
Cleaning Services
Professional cleaners may have been given keys for regular appointments.
Pet Sitters
Dog walkers or pet sitters sometimes keep spare keys for convenience.
Property Managers
If the property was previously rented, property managers or maintenance teams may also have had access.
While most of these people are trustworthy, you shouldn’t rely on assumptions when it comes to protecting your family and belongings.
Rekey or Replace: Which Option Is Right for Your New Home?
Many homeowners aren’t sure whether they should rekey their locks or replace them entirely.
The answer depends on the condition of the existing hardware.
| Rekey Your Locks | Replace Your Locks |
| Locks are in good condition | Locks are damaged or worn out |
| You only want old keys to stop working | You want upgraded security |
| More budget-friendly | Ideal for outdated locks |
| Faster installation | Best for major security upgrades |
If your current locks are still functioning properly, rekeying is often the most practical solution. However, if they’re old, damaged, or no longer meet modern security standards, replacing them can provide better long-term protection.
Professional Residential Locksmith services can inspect your locks and recommend the most suitable option based on your home’s needs.
First 24 Hours After Moving In
The first day in your new home is the perfect time to address basic security.
Start by checking every exterior door, including the front entrance, back door, garage access door, and any basement entrances.
Make sure each lock operates smoothly and that every key works correctly.
If you notice sticking locks, loose handles, or damaged deadbolts, schedule service before those minor issues become larger security problems.
First Week in Your New Home
Once you’ve unpacked the essentials, take a closer look at your home’s overall security.
Walk around the property during both the day and evening.
Pay attention to:
- Poorly lit entryways
- Loose door frames
- Weak strike plates
- Sliding doors
- Basement windows
- Side gates
Identifying these weak points early allows you to improve security before they become vulnerabilities.
First Month: Upgrade Your Home’s Security
Once you’ve settled into your new home, it’s time to think beyond the locks. While changing or rekeying your locks is an excellent first step, creating a complete security plan helps protect your property for years to come.
Consider evaluating other areas of your home, including:
- Exterior lighting around entry points
- Door frames and strike plates
- Garage door security
- Sliding patio doors
- Basement entrances
- Window locks
Small upgrades made during your first month can significantly reduce security risks and improve your peace of mind.
Common Mistakes New Homeowners Make
Many homeowners unintentionally leave their property vulnerable after moving in. Avoiding these common mistakes can help you maintain a safer home from the start.
Assuming the Previous Owner Returned Every Key
Even if you receive multiple keys at closing, there’s no way to confirm how many copies were made over the years. Friends, relatives, contractors, or previous occupants may still have access.
Rekeying or replacing your locks eliminates this uncertainty.
Delaying Security Updates
It’s easy to focus on decorating, unpacking, and home improvements while putting security on hold. Unfortunately, waiting several months before changing your locks leaves unnecessary risk.
Prioritize security before cosmetic upgrades.
Ignoring Older Locks
A lock that appears to work may still have worn internal components. Older locks are more likely to stick, fail unexpectedly, or provide less protection than modern security hardware.
If your locks show signs of wear, replacing them early can prevent future problems.
Forgetting Secondary Entry Points
Many homeowners secure the front door but overlook side doors, garage entry doors, basement entrances, or patio doors. Every exterior access point should be inspected and secured.
Simple Upgrades That Improve Home Security
Changing your locks is only one part of protecting your home. Several affordable improvements can make your property even more secure.
| Security Upgrade | Benefit |
| High-security deadbolts | Better resistance against forced entry |
| Reinforced strike plates | Stronger door protection |
| Motion-activated lighting | Deters unwanted visitors |
| Video doorbells | Monitor visitors remotely |
| Smart locks | Convenient keyless access |
| Window locks | Additional protection for ground-floor windows |
These upgrades work together to create multiple layers of security instead of relying on a single lock.
Should You Choose Rekeying or New Locks?
If your existing locks are in good condition, rekeying is often the most cost-effective option.
However, replacing your locks may be the better choice if:
- The locks are more than 10–15 years old.
- They have visible rust or damage.
- The key frequently sticks.
- The lock feels loose.
- You want smart lock technology.
- You want matching hardware throughout the house.
A professional locksmith can inspect your locks and recommend the best option based on your home’s condition and your security goals.

Frequently Asked Questions
Should I change the locks immediately after buying a house?
Yes. It’s one of the first security tasks every new homeowner should complete because you can’t be certain who still has copies of the existing keys.
Is rekeying enough, or should I replace my locks?
If your current locks are in good condition, rekeying is usually sufficient. If they’re damaged, outdated, or unreliable, replacing them may be the better investment.
How long does it take to rekey a home?
The time depends on the number of locks, but most residential rekeying jobs can be completed during a single service visit.
Can all the locks in my house use the same key?
In many cases, yes. If the locks are compatible, a locksmith can often rekey them so one key operates multiple doors.
What’s the biggest security mistake new homeowners make?
The most common mistake is assuming the previous owner returned every copy of the house keys. Updating your locks removes that uncertainty and gives you full control over home access.
