Peach Locksmith rekeys, installs and services locks across Smyrna from our Marietta base.
As your locksmith in Smyrna, GA, we reset who can open your unit entry door and your mailbox. Your door hardware stays put, and the only keys that work are the ones you hand out. We treat unit doors, shared entries and mailboxes as three separate jobs, because each has a different owner and needs a different fix.
A typical Smyrna move-in call starts with a key ring and a question.
Say you just closed on a townhome in 30080. The seller left two front door keys, a garage-entry key and a mailbox key in an envelope. Who else had copies? Dog walkers, cleaners, a neighbor, a past tenant. Nobody really knows.
We start by counting cylinders: the front deadbolt, the front knob, the door from the garage into the house, and sometimes a patio door. Inside each lock sits a pin tumbler cylinder, the part holding small spring-loaded pins cut to match one key.
Many new owners don't realize the front door might be Schlage while the garage door is Kwikset. Those brands use different keyways, meaning differently shaped key slots, so one key can't run both as they are. We lay out two paths: rekey each lock to its own new key, or swap one cylinder so the whole house runs on a single key.
Then comes the mailbox. On a cluster box unit, the carrier opens the whole front panel with a Postal Service master lock, and we leave that one alone. Your own compartment uses a small cam lock. We replace it and you get a fresh set of keys. Some HOAs like to know when a box lock changes, so give yours a quick heads-up.
You end the visit holding keys you can actually count. That's key control, and it's the whole goal.
The goal: keys you can count.
Key control means knowing exactly who holds a key to your door. After a lease signing or a closing, that list is a guess. A rekey changes the pins inside the cylinder so every old key stops turning, while the lock stays right where it is.
Walk out from Market Village and you pass plenty of townhome communities, and many of them share a cluster box unit for mail.
No third-party dispatch. Crews leave from Marietta and reach metro homes within the scheduled window.
A cluster box unit, or CBU, is one metal cabinet holding a locked mailbox for every home. It sits outside, which matters here.
Outdoor mailbox locks sit in Georgia's humid air all year. A stiff, gritty turn often means the cam lock, the small lock that swings a metal latch, is ready for a swap. Indoor door locks age differently, but a bolt that drags or sticks is worth noting at the same visit.
Some neighbors search by county, not city. Smyrna and Marietta share Cobb County, so the same team covers both. Renters should also read their lease first: many ask you to clear lock changes with management and share a copy.

Booking a rekey starts with one quick call to 678-824-6578.
Tell us your zip code, 30080 or 30082, how many doors you want changed, whether the mailbox is part of it, and whether you rent or own.
Property managers: tenant turnover, the gap between one renter moving out and the next moving in, is the natural window to rekey apartment locks in Smyrna. Shared entries are often planned for the same window.
Your zip code, your door count, and whether the mailbox needs new keys. That's all we need to start.
Each visit follows the same checks, door by door.
Three steps: tell us about your doors, we reset the pins, we test every key.
Call with your zip code, 30080 or 30082, the number of doors and whether the mailbox is included. On site, we check each lock's brand and keyway and note any bolt that drags or sticks.
Each cylinder comes out of the door. We reset the pins to match a brand-new key, then reinstall it. Mailbox lock replacement on a Smyrna CBU is simpler: we pull the old cam lock and fit a new one. If a lock is better replaced than rekeyed, we talk it through with you first.
Every new key goes into every lock it should open. We throw the deadbolt with the door open, then again with it shut, to check alignment with the strike plate. Then we try an old key, which should not turn. The last step is yours: count your keys.
We cover all of Smyrna, 30080 and 30082, plus nearby cities.
That includes Market Village and the townhome streets around it. Across Cobb County and beyond, we also serve Vinings, Mableton, Marietta, Austell and Atlanta, along with Kennesaw to the north and the rest of the communities on our list.
A rekey changes the pins inside the pin tumbler cylinder so old keys stop working, while the lock itself stays on the door. Replacement swaps the hardware. Some locks are better replaced than rekeyed, and we talk that through with you before doing it.
Only if their keyways match. A Schlage front door and a Kwikset garage door use differently shaped key slots, so one key can't run both as they are. Swapping one cylinder can put the whole house on a single key.
Yes. We replace the cam lock on your own compartment and give you new keys. The carrier's Postal Service master lock on the front panel is left alone. Some HOAs like to know when a box lock changes, so let yours know.
Read your lease first. Many leases ask you to clear lock changes with management and share a copy of the new key. Once that's settled, call us with your zip code and door count.
