A locksmith van for Smyrna's offices, driveways and townhomes
4Keys Locksmith is a mobile locksmith working 24/7 in Smyrna, GA. Registered with Georgia's Secretary of State as 4Keys Locksmith LLC, the company is insured and bonded, ALOA certified and NASTF VSP authorized. The work happens at your door or next to your car, never at a counter, because there is no shop: a van dispatched from Brookhaven typically reaches Smyrna in 15 to 30 minutes with the cutter, the pins and the programming equipment on board.
The page starts where a business owner starts after an employee walks out with a key: which cylinders to rekey, in what order, and how to keep track of the new keys afterward. Car keys, fobs and house locks come after that, each with the details that change the work and what to have on hand when you call.
Each job gets its price on the phone before the van rolls, from the lock or key type, the number of cylinders or the programming involved, and the time of day; the published rates are on our pricing page. Speak English or Spanish on the call, whichever you prefer, and read about service in Spanish if that is your language.
When a key leaves with an employee: rekeying the business and keeping control of the new keys
A commercial rekey changes which key a lock answers to without replacing the hardware. Inside a pin tumbler cylinder, key pins sit in holes drilled through the plug with spring-loaded driver pins above them, and only a key whose cuts lift every stack to the shear point, where plug and housing meet, lets the plug turn. To rekey, the technician takes the cylinder out of its housing, replaces the key pins with a new combination and puts it back. The lever, the deadbolt and the door prep stay where they are, and the key that walked out stops working. Worn cylinders, damaged ones, or hardware too light for a commercial door are the exception; the commercial lock change guide and the Mableton page cover when a replacement makes more sense.
Scope comes first. List every lock the departed key could open: the front and rear entries, office and supply-room doors, and any gate, cabinet or padlock set to the same combination. On a master-keyed building, a missing change key and a missing master are different problems. A master-keyed cylinder holds a spacer pin, also called a master wafer, that gives each pin stack a second shear point, so two keys open it. A lost change key means new pins in that door and the doors that share its combination; a master key that leaves means the master level itself changes across the system, following the building's key chart. How those levels are designed is on the Dunwoody page.
Some commercial hardware is built for fast turnover. An interchangeable core is a key cylinder that slides out of the lock with a special control key and slides into a bored cylindrical lock, a mortise lock or a padlock without taking the lock apart. Small format cores share a standard figure-eight shape across makers; large format cores differ by brand. On that hardware, a rekey can be a swap to cores pinned for the new combination, so tell the dispatcher whether your locks take a removable core and whether anyone still holds the control key, since a control key that left with the employee is a bigger leak than a door key.
Key control is what keeps the rekey from being undone later. Count the new keys before they are handed out, write down who received each one and on what date, and collect keys on anyone's last day; a key nobody recorded is a key nobody asks for back. Where copies must be limited, a restricted keyway keeps blanks out of hardware stores, and the Fairburn page explains who can authorize a duplicate. For doors where people come and go too often for metal keys, card or fob readers let a manager switch a credential off the same afternoon, as the Duluth page on access control describes.
Rekeys are done at the building, before opening, during a slow afternoon or after closing, any day of the week. Tell the dispatcher how many cylinders there are, which brand is stamped on them, and whether any door uses mortise, rim or storefront hardware, and the rekey is quoted before the van leaves. The service page is commercial locksmith service.
Five things to settle before the rekey visit
A little preparation turns a rekey into one trip, with the right pins, cores and cylinders already in the van.
- 1
Walk the building with the old key ring
Try every key on the ring in every door, cabinet and gate, and write down what each one opens. That list is the scope of the rekey, and it can turn up a back door or a storage cage nobody remembered.
- 2
Group people by the doors they need
All staff, supervisors, one office, the owner. The grouping tells the technician whether one new combination is enough or whether different cylinders need different keys, which is where a master key plan begins.
- 3
Note what the hardware is
Read the brand stamped on the cylinder face, and look for a figure-eight outline around the keyway, the sign of a small format interchangeable core. Note any narrow aluminum-framed storefront door with a mortise cylinder. A phone photo sent before the visit helps load the right parts.
- 4
Choose when the doors can be worked
Each cylinder is out of its door for part of the visit. Pick a time when that door can stay closed or attended: before opening, a quiet stretch of the day, or after the last shift.
- 5
Plan the handout of the new keys
Have the list of names ready so each new key goes from the technician to the right person, and gather the old keys the same week. Keep that record with the building papers.

Smyrna addresses, exits and cross streets that bring the van to the right door
Smyrna's street-delivery ZIP codes are 30080 and 30082, both in Cobb County, and 30081 is the post office box ZIP. ZIP 30126 is primarily a Mableton ZIP that also accepts Smyrna as a mailing name, so an address reading Smyrna 30126 is covered by the same dispatch, and Mableton has its own page.
From I-285, exit 15 at South Cobb Drive (SR-280) is the one exit inside the city. Exit 16 at South Atlanta Road is signed for Smyrna but sits in unincorporated Cobb, as does I-75 exit 260 at Windy Hill Road. Inside town, give the cross street on Atlanta Road, South Cobb Drive, Cobb Parkway (US-41) or the East-West Connector, which runs toward Cumberland Parkway at the I-285 overpass.
Much of the newer housing is townhouse, cluster-home and condo communities, which means gate codes, shared entrances and new units; give the community name and the building number. For businesses, the van reaches offices and warehouses along Highlands Parkway and shops on Atlanta Road and South Cobb Drive, where panic hardware, storefront cylinders and after-hours access shape the visit.
Just east, Cumberland addresses read Atlanta 30339 even though that area is unincorporated Cobb, and the same van covers them. Marietta borders Smyrna to the north and west, and the metro area page lists every county served from Brookhaven.
