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.

House Locks

What a Jonesboro homeowner calls about, and what each visit involves

Six kinds of home work, each with the detail that changes it. The deadbolt gets its own section further down.

Shut out of the house

The technician gets you back in by non-destructive entry on whatever the door carries, knob, lever or deadbolt. If the key left with a stolen bag or a lost wallet, rekeying that lock before the van leaves means the missing key opens nothing. For what to do while you wait at night, read locked out at night.

Rekeying the locks you have

Rekeying replaces the pin tumblers inside the cylinder so a new key operates it and every earlier key stops. The hardware stays on the door. Whether a rekey or a new lock is the right call is weighed on our Mableton page; the residential locksmith service covers both.

A deadbolt where there was none

A door with only a knob gets a real bolt into the frame. The job is boring the door, setting the backset, mortising the faceplate and anchoring the strike, and each step is explained in the deadbolt section below. Count the doors and note whether any already have a bore.

Handlesets, knobs and levers

Worn entry hardware is swapped for a new knob, lever or handleset laid out on the same backset as the deadbolt above it, so both pieces line up on the door edge. Bring your own set or have one supplied; send a photo of the door edge so the van arrives with a set that fits.

Keypad and app locks

A keypad or app deadbolt goes in like any other deadbolt, then gets its codes set before the technician leaves. Door compatibility, codes and what happens when the battery runs down are covered on our Snellville page.

High-security cylinders

A restricted keyway keeps the copying in your hands: its blanks are sold only through authorized channels, so a duplicate is cut on your authorization. These cylinders fit the front door of a house as well as an office. Say which doors you want on the restricted key and how many keys the household needs; the Georgia residential locksmith page lists the home work in full.
Bore, Backset, Strike, Grade

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.

Door Prep at a Glance

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.

Cross bore2-1/8 in (some models 1-1/2 in)Through the face of the doorWhich deadbolt body fits; a smaller-bore lock in a larger hole needs its adapter or bracket.

Driveway and Parking-Lot Keys

Car keys and fobs, cut and programmed where the car sits

Toyota, Honda, Nissan, Chevrolet, Ford, Hyundai, Kia, Dodge and Ram first, and European and luxury makes too: the van works on American, German, Japanese, Korean, British and Italian cars alike.

Keys locked in the car or the trunk

The car is opened by non-destructive entry; a Lishi pick, an air wedge and a long reach tool ride in the van for that purpose. A trunk with the keys inside is its own job (trunk lockout), so say which it is. With a child or a pet inside, call 911 first, whatever the weather. Service details: car lockout.

A spare while one key still works

A second key made from a working one is the simpler job, and the dispatcher asks whether the car has a key slot or a start button, because the part differs: a blade with a chip for the first, a smart key for the second. On Toyota and Honda keys a stamp on the blade names the chip, and our Lithonia page reads those stamps one by one. See car key duplication and the Toyota locksmith page.

When the last key is lost

A fresh blade is cut to the code on record for your VIN, then its transponder is registered with the car's immobilizer while the technician is parked beside it; lost keys are wiped from memory wherever the system permits. Some cars refuse an owner routine with a single key: STRATTEC documents a GM high-security key from 2017 on that needs two recognized keys to add one, so a programming tool does it instead. Give the year on the call and the dispatcher confirms your route. Read all keys lost and the Chevrolet locksmith page.

Fobs and smart keys, including one you bought

Flip keys, remote-head keys and push-button proximity fobs get paired to the car in your driveway. If you already ordered one, a fob you bought online is programmed as long as the part number, FCC ID and frequency match your car. A healthy fob that forgot the car is registered again, while a fob with a history of failing, or one that went through the wash, gives way to a brand-new fob covered by warranty (deprogrammed or broken fob). Service: smart key fob programming.

Ignitions and snapped keys

Worn wafers, a failed actuator pin and a worn key blade feel alike from the driver's seat, so key and cylinder are both checked before a price is given (key will not turn, ignition repair). A blade broken in the lock is drawn out first; keep both halves, since the chip in the head may still work (broken key in the ignition).

Modules, fleets and dealer-level access

Key work runs with dealer-level software under NASTF VSP, after the title or registration is checked against a photo ID in the same name. A replaced control module is set up at the car (module programming, explained on our Doraville page), and company pickups and vans are keyed one after another in the yard (fleet key programming). Also see the Ford and Honda pages.
Jonesboro Offices and Shops

Offices and shops in Jonesboro: who holds a key and which doors it opens

For offices, shops and warehouses with a Jonesboro address, from a single back door to a building full of staff keys.

Office deadbolts and door hardware

Office and shop doors take heavier hardware than a house, and the door decides the job: a hollow steel door in a steel frame, a solid wood door and an aluminum storefront each take a different lock. Replacing a worn lockset or adding a deadbolt to a back door starts with the door type, its thickness and the holes already in it, so send a photo of the door edge.

A key left with a former employee

A key that walked out with a former employee is dealt with by rekeying every cylinder it opened, and new keys are cut at the building for the people who stay. List those doors before the visit. Keeping track of keys through staff changes is the subject of our Smyrna page.

One key per level

A master key system gives the owner one key for everything, each department its own, and each room its own, all drawn up on a key chart. Bring the list of doors and of who needs which. Planning notes are in the master key system setup guide, and designing one for a whole building is explained on our Dunwoody page.

Card readers and keypads

Staff doors move from metal keys to codes, cards or fobs, and a departing employee's card or code is deleted instead of a lock being rekeyed. On systems that keep a log, you can see which credential opened which door. Say how many doors and how many people, and whether any door already has a reader.

Push bars on exit doors

An exit device lets anyone inside leave with one push while the street side stays locked. New installs, a bar whose latch has stopped catching and the outside trim with its key cylinder are all part of the work. Measure the door width and note the door material before you call; our Tucker page covers the device types.

After closing, on the wrong side of the door

When the shop or office will not open at night, the door is opened for the owner or a manager, and a missing key can be answered with a rekey before the technician packs up. How that night call runs, including what the technician checks at the door, is on our Morrow page; an aluminum-and-glass storefront door has its own narrow hardware.

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.

Martavious Stewart1 week ago

I was incredibly grateful to receive a same-day appointment. The locksmith was highly professional, demonstrating excellent communication and customer service skills. I had previously called another locksmith, but they couldn’t program my key. Fortunately, David from 4keys locksmith came to my place, programmed my key, and even cut a new one for me. I want to express my sincere gratitude for his assistance.

FAQ - Deadbolts, Tara Boulevard and County Lines: Jonesboro Answers

Adding a deadbolt, choosing its grade and cylinder, why doors give way at the strike, a smaller-bore lock, a thick door, finding the van on Tara Boulevard and Jonesboro addresses in Henry or Fayette County.

Yes. The technician bores the door for the deadbolt, a 2-1/8 inch cross bore and a 1 inch edge bore on standard models, lays it out on the same backset as the knob so the two line up, mortises the faceplate flush, and cuts the jamb for the strike. Tell the dispatcher the door material and, if you know it, the thickness, since standard deadbolts fit doors 1-3/8 to 1-3/4 inches thick.
Buy your own or have one supplied. Look for the BHMA marking on the package: residential deadbolts are tested under ANSI/BHMA A156.40, which includes security tests such as loading the door against the bolt with 1,350 pounds of force. Keep the box, because its bore size and backset tell the technician whether it fits your door before anything is drilled.
A single-cylinder deadbolt takes a key outside and has a thumbturn inside. A double-cylinder deadbolt takes a key on both sides, so it cannot be turned by hand from inside, and everyone in the house needs a key to get out. Weigh who lives there and how fast they would need to leave before choosing.
Because the weak point is the strike, not the bolt. A police crime prevention officer wrote that the forced doors he saw failed where the deadbolt entered the strike, and he recommends longer screws that reach the studs instead of stopping in the trim. Screws through the jamb into the framing studs, and a reinforcement plate where the deadbolt includes one, make the frame hold. Ask for it when you book.
The name of the business or building in front of you, the nearest cross street, and the side of the boulevard. For a county building such as the justice center at 9151 Tara Blvd, add the lot and the row. Give the color, make and model of the car so the technician goes straight to it.
Yes. ZIP 30236 reaches into Henry County and 30238 into Fayette County, and the van is routed by street address, not by county. Give the full address on the call, and the quote and the arrival time from Brookhaven are given the same way.
Check the box first. Schlage covers both the 2-1/8 inch and the 1-1/2 inch cross bore in its installation guide, with a bracket removed for the smaller hole, and Kwikset lists some of its deadbolts for a 1-1/2 inch borehole. Keep the box and every part in it, and the technician checks the lock against the door before anything is drilled or mounted.
Kwikset rates its standard deadbolts for doors 1-3/8 to 1-3/4 inches thick and offers a thick-door kit for doors up to 2-1/4 inches. Put a tape measure on the edge of the door before you call and read the number to the dispatcher along with the door material, so the lock or the kit that fits is on the van.

A door that needs a deadbolt, or a car that needs a key? One call covers both.

Say how many doors or which car, and the street it is on. The dispatcher quotes it before a van heads to Jonesboro, in English or Spanish.

The price depends on the job and the components it needs; you get the exact total on the phone before the technician is sent. See our reference prices.
