Before you carry a single box through that new front door, take 20 minutes to walk every entry point in the home with fresh eyes. In my experience rekeying houses across the Charlotte area, I've found that roughly 60% of resale homes still have at least one lock that was never changed after the previous owner moved out — meaning strangers you've never met may still have a working key to your property.
This pre-move-in checklist will help you catch every vulnerability before it becomes a 2 a.m. emergency.
Run This Lock Audit Before You Accept a Single Key
The day of closing, ask the seller for every key associated with the property — front door, back door, garage, shed, mailbox, pool gate, the works. Count them. Then ask how many copies were made over the years. Most sellers genuinely don't know.
That uncertainty is exactly why a pre-move-in lock audit matters. You're not being paranoid; you're being systematic. Grab a notepad, walk the perimeter, and mark down the brand, condition, and grade of every lock you find. A Grade 1 deadbolt (the highest residential rating from ANSI/BHMA) looks and feels different from the builder-grade Grade 3 hardware that developers install to keep costs down.
Front Door and Entry Points: Start Here
Your front door is the most targeted entry point in any break-in, so it deserves the most scrutiny. Check for:
- Deadbolt throw length: A quality deadbolt extends at least 1 inch into the door frame. Anything shorter is easy to kick in.
- Strike plate screws: Builder-grade strike plates often use ¾-inch screws. Replace them with 3-inch screws that anchor into the stud, not just the door casing.
- Lock brand and age: Schlage and Kwikset are reliable brands. If you see a no-name lock or one that wiggles when you grip it, budget for a replacement before move-in day.
- Sliding glass doors: These need a secondary pin lock or security bar. The factory latch alone won't stop a determined push.
Check every exterior door — front, back, side, and any door leading from an attached garage into the living space. That garage-to-home door is often the most overlooked and the easiest to exploit.
Interior Locks, Garages, and Outbuildings
Interior privacy locks (bedrooms, bathrooms) rarely pose a security risk, but check that they all function smoothly. Stiff or misaligned locks often mean the door frame has shifted, which can signal foundation movement worth investigating.
For the garage, test the automatic opener with every remote you received. Change the access code immediately — it takes less than 60 seconds on most Chamberlain and LiftMaster units. If there's a keypad on the outside, reset that PIN as well.
Detached garages, workshop sheds, and pool gates tend to have padlocks. I've walked properties in Charlotte neighborhoods where the same combination padlock had been used for 12 years. Inspect the shackle for rust and the body for signs of shimming or drilling, and swap out anything that looks compromised.
When to Rekey vs. When to Replace Entirely
Here's the decision most new homeowners get wrong: they assume replacing a lock is always better than rekeying. It isn't — at least not automatically.
Rekeying reconfigures the internal pin tumblers so that all existing keys no longer work. It costs significantly less than a full hardware replacement (typically $20–$50 per lock with a locksmith on-site) and makes perfect sense when the lock hardware itself is in good condition and is a Grade 1 or Grade 2 deadbolt.
Replacement is the right call when the lock is worn, low-grade, or you want to upgrade to a smart lock or keypad entry. If you're buying an older Charlotte home with original builder hardware from the 1990s, replacement is almost always worth the investment.
I generally recommend rekeying every exterior lock as a baseline minimum, then replacing any lock that fails the grade or condition test. A reputable Charlotte locksmith can rekey an entire house in under two hours and will carry a range of replacement hardware in the service vehicle, so you're not waiting on a second appointment.
Don't Forget Your Car: Key Fobs and Automotive Locks
New homeowners often budget carefully for door hardware and completely forget about vehicle security. If you're purchasing a home with a shared driveway or a garage that required a gate fob, confirm that all previous residents' fob codes have been deleted from the system.
For your own vehicles, this is also a smart time to audit your key situation. If you've been putting off replacing a cracked key fob or getting a spare cut, do it before the chaos of moving in fully takes over. Key fob replacement in Charlotte can run anywhere from $75 to $250 depending on the make and model — dealerships tend to charge at the high end, while a qualified automotive locksmith in Charlotte NC can usually program a replacement key or fob for considerably less with faster turnaround.
Transponder keys, proximity fobs, and push-button start systems all require programming, not just cutting. Make sure whoever handles your spare key has the right equipment for your vehicle's year and model.
How to Find a Trustworthy Locksmith in Charlotte
With any local service trade, scam operations are a real concern. In the locksmith industry specifically, bait-and-switch pricing — where a company advertises a $15 "pop a lock cheap" rate and then charges $150 on-site — is well-documented in consumer complaint filings nationwide.
When you're researching locksmiths in Charlotte, look for these signals of legitimacy: a verifiable physical address, a technician who arrives in a marked vehicle, and a written estimate before any work begins. Check Google reviews for mentions of pricing transparency, not just star ratings. Ask directly whether the technician is the business owner or a dispatched contractor — it matters for accountability.
Knowing solid locksmith numbers ahead of time, before an emergency, is one of the simplest ways to protect yourself from a rushed, bad decision at 11 p.m. Save a trusted contact in your phone the same week you move in. That one habit has saved countless Charlotte homeowners from overpaying in a moment of stress.
Completing this audit before move-in day doesn't just improve your security — it gives you a clear, documented picture of exactly what hardware is in your home, when it was last serviced, and what upgrades are worth planning for in year one.
