The locksmith comes to the door in Jonesboro, with the shop in the back of the van
For Jonesboro, GA, 4Keys Locksmith is the mobile locksmith that answers 24/7. It is ALOA-trained, NASTF VSP authorized for vehicle security work, insured by The Hartford, and on record with the Georgia Secretary of State under the name 4Keys Locksmith LLC. No storefront sits between you and the work. Drills, bits, lock stock, the key cutter and the programming equipment travel in the van, which drives from Brookhaven to your Jonesboro address.
At the house, that means a new deadbolt fitted properly, a rekey after a move, or entry when the keys are on the wrong side of the door. At the car, it means a key cut to the code and programmed to the immobilizer, or a fob set up at the curb. At an office or shop, it means rekeys, master keys, card readers and push bars. Below, each one comes with the details that shape the visit and the things worth having in hand before you dial.
The dispatcher gives you the price on the phone before any van is sent, and a visit that falls between 9 PM and 7 AM local time, and on Sundays and federal holidays carries an after-hours surcharge that is named inside that price. The reference rates live on the 4Keys pricing page. Call in English or in Spanish, whichever is easier for you.

Installing a deadbolt properly: the bore, the backset, the strike and the grade
A deadbolt holds only as well as the four things around it: the holes it sits in, its distance from the door edge, the strike it throws into, and the quality of the lock. Adding one to a Jonesboro door that never had one is carpentry as much as lock work, and each of those four decides whether the bolt slides cleanly on the first turn and whether it holds when someone leans on the door from outside.
The holes come first. Standard residential deadbolts are made for a 2-1/8 inch cross bore through the face of the door and a 1 inch edge bore that meets it, according to Kwikset and Schlage door-prep documents; some models sit in a smaller 1-1/2 inch bore instead. The cross bore is cut with a hole saw, and the two holes have to meet square for the bolt to slide freely. Door thickness matters as well: Kwikset rates its standard deadbolts for doors 1-3/8 to 1-3/4 inches thick, with a kit for doors up to 2-1/4 inches.
Then the backset, the distance from the edge of the door to the center of the cross bore. The two standard sizes are 2-3/8 and 2-3/4 inches, and adjustable bolts handle both; on a Schlage bolt the change is made by twisting the faceplate. When the door already carries a knob or handleset, the new deadbolt is laid out on the same backset so the two pieces line up. The faceplate is set into a shallow mortise chiseled in the door edge so it sits flush and the door closes without rubbing.
The strike is the half people forget, and it is where a forced door gives way. A police crime prevention officer wrote in his newspaper column that the forced doors he saw in his career failed where the deadbolt entered the strike, and his fix is longer screws that pass through the jamb into the framing studs instead of stopping in the trim. Some deadbolts ship with a reinforcement plate that goes on the frame under the strike. The bolt also has to throw fully into the strike hole; Schlage's own guide says that if it binds, the strike or the jamb is adjusted. Ask for the strike to be anchored into the framing when you book, and it is part of the visit.
Last, the lock itself. The Builders Hardware Manufacturers Association tests residential deadbolts under ANSI/BHMA A156.40, which covers durability, security and finish and includes a test that loads the door against the bolt with 1,350 pounds of force. Look for the BHMA grade on the box. Decide too between a single-cylinder bolt, keyed outside with a thumbturn inside, and a double-cylinder bolt keyed on both sides, which needs a key to get out, so think about who in the house has to leave in a hurry.
To book it, tell the dispatcher how many doors, whether each one is bored already, what the door is made of (wood, steel or fiberglass), and whether you bought the deadbolt or want one supplied. If the lock is yours, keep the box: the technician checks its bore size and backset before drilling. A deadbolt that exists but sticks or no longer latches is a repair, covered on our Norcross page.
The measurements behind a deadbolt install, and why each one matters
Sizes as the Kwikset and Schlage installation documents and the BHMA standard state them. Check your own lock's box before a hole is drilled.
| Measurement | Standard size | Where it is on the door | What it decides |
|---|---|---|---|
| Cross bore | 2-1/8 in (some models 1-1/2 in) | Through the face of the door | Which deadbolt body fits; a smaller-bore lock in a larger hole needs its adapter or bracket. |
| Edge bore | 1 in | Into the door edge, meeting the cross bore | Where the bolt travels; it has to meet the cross bore square for the bolt to slide freely. |
| Backset | 2-3/8 in or 2-3/4 in | Door edge to the center of the cross bore | Whether the deadbolt lines up with the knob or handleset already on the door. |
| Door thickness | 1-3/8 to 1-3/4 in (kit to 2-1/4 in) | The whole slab | Whether the standard lock fits or a thick-door kit is needed. |
| Faceplate mortise | Shallow, flush with the edge | Door edge around the edge bore | Whether the door closes without rubbing on the frame. |
| Strike and screws | Screws reaching the framing studs | Jamb, opposite the bolt | How the door holds against force; a reinforcement plate adds to it. |
| Lock grade | ANSI/BHMA A156.40 (residential) | On the package | Durability and security testing, including a 1,350 lbf load on the bolt. |

Finding the van in Jonesboro: ZIP codes, exits and the kind of door it is
Jonesboro mail goes to two street ZIP codes, 30236 and 30238, with 30237 used only for post office boxes. Both street ZIPs run past the city line: part of 30236 lies in Henry County and part of 30238 in Fayette County. The van is routed by the street address, so a Jonesboro address in either county is covered the same way.
Tara Boulevard, which is US 19/41, is the main road through town. No I-75 exit sits inside Jonesboro itself: exit 235 (US 19/41) is signed for Jonesboro from the north, exit 228 (SR 138) is signed for Jonesboro and Stockbridge from the south, and SR 54 comes down from exit 233 in Morrow to meet SR 138 in Jonesboro. On Tara Boulevard, give the nearest cross street and the name of the business in front of you. If the car is at a county building such as the Harold R. Banke Justice Center, 9151 Tara Blvd, say which lot and which row.
The kind of property changes what the technician brings. A single-family house where a deadbolt is being added needs the door material and thickness. An apartment or townhome community with a gate needs the gate code or someone to meet the van. An office needs the list of doors a missing key opened. The same dispatch covers Riverdale and Ellenwood as well.
