Marietta, Cobb County

A locksmith that drives to Marietta, for your car, your house and your business

4Keys Locksmith is a mobile, 24/7 locksmith in Marietta, GA that is NASTF VSP authorized, ALOA certified, insured and bonded, and registered with the Georgia Secretary of State as 4Keys Locksmith LLC. There is no counter to visit: the key cutter, the programming equipment and the lock hardware ride in the van, the way a fully mobile locksmith works, and vans leaving Brookhaven typically reach Marietta in 15 to 30 minutes.

The work covers cars (lockouts, new keys, fobs, ignitions, modules, fleets), houses (lockouts, rekeys, new locks, smart and high-security locks) and businesses (rekeys after staff leave, master keys, access control, panic bars, storefronts). Each is explained below with what changes the job and what to have ready.

Every job is quoted on the phone before the van leaves, and the published rates are at 4Keys pricing. Calls are answered in English and Spanish; this page in Spanish is Cerrajero en Marietta.

Car Locksmith Service

Car keys, fobs and ignitions, handled where the car is parked

Honda, Toyota, Ford, Chevrolet, Nissan, Hyundai, Kia, Dodge, Ram, Jeep and GMC, plus European and luxury models. Each card says what decides the job and what to have ready.

Car lockout

The door is opened by non-destructive entry, with tools such as an air wedge, a long reach tool or a Lishi pick. What changes the job is where the keys and the car are: keys in the trunk are a trunk lockout, and a gated lot or a deck needs the code or the level and row. See car lockout service and what to do with keys locked inside.

New key, spare key or all keys lost

With one working key, a spare is cut and programmed at the car (car key duplication). With none left, it is all keys lost: the blade is cut by code from the key code tied to the VIN and a new transponder chip is programmed to the immobilizer, which is why it is quoted above a spare. The dispatcher confirms the route for your year on the call. Have the title or registration and a photo ID in the same name ready. See lost car key replacement.

Key fob and smart key programming

Remote-head keys, flip keys and proximity fobs are programmed at the car, and so is a fob you bought online once its FCC ID, frequency and part number match your car. A sound fob that lost its pairing is re-registered; one that keeps failing or got wet is replaced by a new fob under warranty, as the deprogrammed or broken fob guide explains. After a battery change, start at key fob not working. Service: smart key fob programming.

Ignition repair

A key that will not turn, spins with no resistance, or binds halfway points to the ignition lock cylinder, the key blade, or the link to the switch behind them. Worn wafers and a broken actuator pin are different repairs, so cylinder and key are checked before quoting. Guides: key will not turn and key spins in the ignition. Service: ignition repair.

Broken key extraction

A blade snapped in the ignition or a door lock is drawn out of the keyway with extraction tools first. Keep both halves: the bitting can be read to cut a new blade, and the chip in the key head can still be good. See broken key extraction and a key broken in the ignition.

Module programming

A replacement body control module, immobilizer module or engine computer may need to be programmed to the car and its keys before the engine will run. The technician does it at the vehicle with dealer-level software under NASTF VSP; say which module was replaced. See ECU and module programming.

Fleet and work van keys

Pickups, cargo vans and service trucks get spares, fobs and all-keys-lost work in the yard, one after another, with no dealer trip. Have a list of VINs; the documents required for the case are requested on the call. See fleet and van key programming.

European and luxury models

BMW, Mercedes-Benz, Audi, Volkswagen, Land Rover and Lexus keys are programmed with the same dealer-level access, across six origins: American, German, Japanese, Korean, British and Italian. The dispatcher says whether the key is on the van or ordered first. See luxury key programming.

Residential Locksmith

House locks in Marietta: entry, rekeys and new hardware

What each home job involves and what changes it.

House lockout

Entry starts with non-destructive work on the knob, lever or deadbolt you have. If the key is lost, the same visit can rekey the lock. Night calls fall under emergency locksmith service.

Rekeying

New pins inside the cylinder make the old keys useless while the lock stays on the door. Doors can be keyed alike so one key runs them all. See residential locksmith service.

Lock change and deadbolt installation

A worn or broken lock is replaced, and a deadbolt can be added to a door that only has a knob. A door never drilled for one has to be bored and fitted with a strike, so tell the dispatcher whether the hole exists and how many doors there are.

Smart locks

Keypad and app-controlled deadbolts are installed and set up with their codes, in the existing bore where the lock allows it. Buy your own or have one supplied.

High-security locks

Restricted keyways mean the keys cannot be copied at a hardware counter; duplicates come only through an authorized channel. Name the door and the brand you want.

Older houses, original hardware

A sound original cylinder is rekeyed; a worn one is replaced with hardware that fits the existing door prep. A photo of the lock sent before the visit helps the dispatcher load the right parts.

Commercial Locksmith

Business locks: rekeys, master keys, access control and exits

For offices, shops, clinics and warehouses: who can open which door, and how fast that changes.

Rekey after staff turnover

When an employee leaves with a key, every cylinder that key opened is rekeyed. List those doors first; on a master-keyed building the rekey follows the key chart. See commercial locksmith service.

Master key systems

A master for every door, sub-masters by department, change keys for single rooms, all on a key chart, with restricted keyways against copies. Bring a list of doors and who needs each. The master key system setup guide covers the planning.

Access control

Keypads and card or fob readers replace metal keys on staff doors, with credentials switched off the day someone leaves and, on systems that log entries, an audit trail.

Exit devices and panic bars

Push bars let people leave with one push while the door stays locked from outside. The work covers installation, bars that stick or no longer latch, and outside trim with a cylinder. Tell the dispatcher the door type (steel, aluminum or wood) and its width.

Storefront locks

Aluminum storefront doors take narrow-stile hardware: mortise cylinders, hook-bolt deadlocks, and hinges that decide how the door meets the lock.

Business lockout after hours

An owner or manager locked out is let in at any hour; a lost key means a rekey in the same visit.

Car Key Programming, In Depth

How a car key gets programmed: on-board routines, programming tools and dealer-level software under NASTF VSP

A car key does two jobs. The blade, cut to the key code, turns the locks; the transponder chip in the head talks to the immobilizer, which lets the engine run only for a registered chip. Cutting copies the blade, programming teaches the car a new chip, and cloning copies a working chip onto a new one. The route a new key takes depends on the make, the year and how many working keys you still have.

The first route is an on-board programming routine, a sequence of ignition and door actions that puts the immobilizer into learn mode using keys the car already knows. On General Motors vehicles with the Circle Plus key (stamped PK3 or with a plus sign), STRATTEC documents an add-a-key routine that runs with one original key. Ford's owner routine for PATS keys needs two coded keys, and Chrysler and Dodge vehicles with Sentry Key follow the same two-key rule. Honda has no on-board immobilizer routine, so a Honda spare goes through a programming tool even with a working key. The 2014 to 2016 Silverado and Sierra run the other way: a timed relearn of about 30 minutes registers a new key when none is left and erases the old ones.

The second route is a programming tool at the diagnostic port. It covers the one-key case the owner routine refuses and the case where no key is left, and where the system allows it the lost keys are erased from memory so they can no longer start the car. Ford's own manual sends owners without a spare coded key to a dealer on a tow truck; 4Keys Locksmith does that programming at the car in Marietta.

The third route runs through the manufacturer, which releases the security data by VIN only to registered professionals. For 2014 and later Stellantis vehicles (Chrysler, Dodge, Jeep and Ram), the key programming PIN is bought by VIN through the Stellantis portal with an active NASTF VSP credential. NASTF, the National Automotive Service Task Force, runs the Vehicle Security Professional registry that locksmiths enroll in to program keys, order key codes and reset immobilizers, and 4Keys Locksmith is NASTF VSP authorized. Dealers do the same work with their own tools, Ford's FDRS and Toyota's Techstream among them; do locksmiths have dealer software answers whether a locksmith reaches that level.

That access is why proof of ownership comes first: 4Keys checks the title or registration against a photo ID in the same name before any key is programmed. Your part is short: the year, make and model (or the VIN), how many keys still work, and any fob you already bought. The dispatcher confirms the route and quotes the job on the first call. More in when every key is lost, programming a fob bought online and a fob that lost its programming.

Key Systems by Make

Which route a key system takes: examples from the parts catalogs

Years exactly as the STRATTEC catalogs, the manufacturer bulletins and the key vendors list them. Your own key type is confirmed from the VIN on the call.

Vehicle	Years listed	Key system	Programming route
Chevrolet Silverado	2007-2013	Circle Plus (PK3) transponder blade, separate remote	On-board add-a-key routine with one original key; the new blade is cut to match.
Chevrolet Silverado, GMC Sierra	2014-2016	Molded encrypted transponder key	Added with one recognized key; with none, a timed relearn of about 30 minutes that erases the old keys.
Ford F-150	2004-2010	PATS transponder blade (Texas 4D-63)	Owner routine needs two coded keys; with one or none, a PATS-capable programming tool at the truck.
Honda Accord	2003-2008	"V" chip transponder blade (ID46)	No on-board immobilizer routine: programming tool even with a working key; remote programmed separately.
Ram pickup	2008-2017	FOBIK fob-integrated key	Customer mode needs two working keys; from 2014, the PIN is issued by VIN through Stellantis to NASTF VSP registrants.
Toyota Tacoma	2005-2023	Transponder key or smart key, by VIN	With every master key lost, Toyota's reset (T-SB-0057-18) erases all registered keys; the dispatcher confirms the route on the call.
Hyundai	By VIN	Chip key or smart key; some models have no immobilizer	Immobilizer models are programmed with the 6-digit vehicle PIN; models without one take a cut key and a remote.

Sources: STRATTEC catalogs (2020, 2008), Toyota T-SB-0057-18, Hyundai and Stellantis documents. Make by make: Chevrolet, Ford, Honda and Toyota locksmith pages.

Before the van leaves: what the dispatcher asks and how the price is set

For a car, give the year, make and model (or the VIN from the registration), how many keys still work, and whether you already bought a fob. For a house or business, count the doors. The dispatcher then quotes the job on the phone, based on the key or lock type, the programming route and the hour; the published rates are on the pricing page. Nothing is dispatched until you agree to the price.

Service Area

Where the van goes in Marietta, and what changes at each kind of property

4Keys Locksmith covers every Marietta mailing address, in ZIP codes 30008, 30060, 30062, 30064, 30066, 30067 and 30068, inside the city limits or in unincorporated Cobb County with a Marietta ZIP. Give the street address, or the business or complex name.

From I-75, exits 261 (Delk Road), 263 (SR-120), 265 (SR-120 Alternate) and 267A (Canton Road) put you in Marietta, and I-575 begins just past them at exit 268. On Cobb Parkway (US-41) or Roswell Road (SR-120), name the nearest cross street; near the Square, say which side. The same dispatch covers Smyrna to the south and Kennesaw next door.

At a gated apartment complex, give the gate code on the call or meet the van at the gate. At an office park or medical building with card readers, access control, exit devices and override keys fit in one trip. In a hospital or campus deck, such as WellStar Kennestone on Church Street or the Kennesaw State Marietta Campus on South Marietta Parkway, give the deck, level and row, since the car is worked on in its space. At a fleet yard, vehicles are keyed one after another.

Best service in town, Juan came so fast, very reliable and professional and the price was unbelievably affordable. I will recommend this company 100%. Thank you so much.

David was professional, easy to work with, and even swung by my hotel to take me to the parking lot at Truist Park where I had lost my “push to start” key in the stadium.

FAQ - Marietta Locksmith Questions, Answered in Full

Keys with no original, cloning, ownership papers, fobs bought online, ignitions, price and night hours, gated lots, a child in a locked car, and rekeying a new house.

Yes. With no key left, 4Keys Locksmith cuts a new blade from the key code tied to your VIN and programs a new transponder chip to the immobilizer at the car in Marietta, erasing the lost keys where the system allows it. The dispatcher confirms the route for your make and year on the first call.

Cloning copies the data from the chip in your working key onto a new chip, so the car reads the copy as a key it already knows. Programming registers a brand-new chip in the immobilizer as an additional key. Cloning needs a working key; programming is the route when no key is left or when lost keys must be removed from memory.

The title or the registration for the vehicle, plus a photo ID in the same name. The technician checks both at the car before any key is cut or programmed. If the registration is inside the locked car, say so on the call and the dispatcher explains how the check works in that case.

Yes, when the part matches your car. Read the FCC ID, frequency and part number from the fob or its listing to the dispatcher; a matching fob is programmed at the car. If yours is the wrong part, the technician can bring a new fob that fits, covered by the 4Keys warranty.

Try the spare. If it turns smoothly, your everyday key is worn, and a new key cut by code fixes it. If both keys stick, the wafers in the ignition lock cylinder may be worn, or the steering column lock may be holding it, which turning the wheel while turning the key releases. If the key spins with no resistance, the link to the ignition switch has failed.

The dispatcher quotes the job on the phone before a van is sent, based on the key or lock type and the programming route. An after-hours surcharge applies between 9 PM and 7 AM local time, and on Sundays and federal holidays, and it is included in the quote you hear on that call. A Saturday daytime call carries no surcharge. Published rates are on the 4Keys pricing page.

Yes. For a gated apartment complex, give the gate code on the call or meet the van at the gate. For a hospital, campus or office deck, give the deck name, the level and the row. The car is worked on in its space.

Call 911 first, in any weather and at any temperature. Once the child or the animal is safe, call 4Keys for the keys, the door or the lock.

Rekey when the locks work and you like them: the pins change and the old keys stop working. Replace when a lock is worn, damaged or below the security you want, or when you want a smart lock or a high-security cylinder.
