The locksmith comes to the job: cars, offices and homes across Alpharetta
In Alpharetta, GA, 4Keys Locksmith works as a fully mobile locksmith, day and night, that is NASTF VSP authorized for vehicle security data, ALOA certified, bonded and insured, and registered as 4Keys Locksmith LLC with the Secretary of State of Georgia. The van is the workshop, with its key cutter, programming equipment and lock parts; it sets out from Brookhaven and typically reaches Alpharetta in 15 to 30 minutes.
This page's long section is about one situation: a smart key that goes dead while you stand at the car. Around it sits the full list of what we do, for vehicles, businesses and houses, noting for each one the detail that shifts the work and the papers or parts worth having out.
Every job is priced over the phone and the van goes out only once you say yes; standard figures sit on the 4Keys rate sheet. Talk to dispatch in English or in Spanish, and our Spanish-language service is described at cerrajero en español.

Proof it is your car, for a family car or a company vehicle
Before any key or smart key is programmed, the technician compares the title or registration with your photo ID, and both have to carry one name. That check comes with the access that NASTF VSP authorization gives to manufacturer security data. For a car in a relative's name, the named owner meets the van with their ID. For a company vehicle, dispatch tells you on the call which documents that case needs.
A smart key with a dead battery: the hidden blade, the backup start and the coin cell
A smart key, the proximity fob behind a push-button start, runs two separate radio jobs from one shell. The coin cell powers the buttons and the passive-entry signal that lets the car sense the fob in a pocket or a bag. The immobilizer transponder in the same shell has no battery at all: an antenna coil in the car energizes it when the fob is held close enough. So a flat cell kills keyless entry and the buttons, yet the engine can still start once the fob sits where the car can read it.
Smart keys also carry a mechanical emergency key. Nissan's 2015 Altima manual says the Intelligent Key contains one, released with a lock knob; BMW's 3 Series manual says the integrated key opens the driver's door and the glove compartment; the 2012 Mercedes-Benz C-Class manual describes a detachable key freed with a catch; Kia's 2025 Seltos manual lists a removable mechanical key inside the smart key. On Ford Intelligent Access fobs and on GM's 2014 and later truck fobs, the STRATTEC catalog lists that emergency key as a non-transponder blade, so it turns the door lock and nothing else. Opening the car and starting it are separate steps, set out below.
Your own key, a dead cell: five checks before calling for a new fob
This is the owner's routine for a key that belongs to the car. If any step fails, the technician picks it up from there.
- 1
Release the emergency key and open the driver door
Slide the release or knob on the fob, draw out the blade and use it in the driver door lock. If the blade is missing from the fob, or it no longer turns the door, that is a key to be cut, and the dispatcher can send one cut to the car’s code.
- 2
Put the fob where the car reads it without power
Makers place that spot differently. On the 2015 Altima: foot on the brake, touch the Intelligent Key to the start switch, then press that switch inside ten seconds of hearing the chime. On the 2016 3 Series: hold the remote to the marked spot on the steering column and press Start/Stop inside 10 seconds. Your owner’s manual shows the exact spot for your car, under a heading about a weak or dead key battery.
- 3
Fit a fresh coin cell of the size printed on the old one
Cells differ from fob to fob, even inside one brand: the Lexus HYQ14ACX key takes a CR1632, the HYQ14FBA a CR2032, and the 2018-2024 Wrangler smart flip key a CR2450. Note which face is up before the old cell comes out, because a cell fitted upside down does nothing.
- 4
If the new cell changes nothing, look at the fob itself
Infiniti’s bulletin for a dead Intelligent Key starts with cracks and water inside the case, and only then checks how the cell sits and its voltage. BMW documents a G30 5 Series key (cars built from March 2018) put into a deep sleep by static discharge and woken by pressing a button or refitting its battery. A cracked or water-damaged fob gets exchanged for a new one that our warranty covers.
- 5
When the car still reports no key
If the fob starts the car from the backup spot but not from your pocket, radio interference or a car-side antenna is the suspect, which our Austell page explains. If it will not start the car even from the backup spot, the car is no longer recognizing that key's transponder, and a new smart key is programmed at the car after the dispatcher confirms the route for your model year. More in key fob not working.
Where the emergency key and the dead-fob start are, make by make
Model years are copied as printed in each owner's manual, the STRATTEC catalog or the vendor listing. Trim level decides whether a car came with a smart key at all, and dispatch identifies yours by VIN when you phone.
| Vehicle | Years listed | Smart key and emergency key | With a dead cell |
|---|---|---|---|
| Nissan Altima | 2015 manual | Intelligent Key holding a mechanical key, freed with a lock knob | Brake down, fob touched to the start switch, switch pressed before ten seconds pass after the chime. |
| Nissan Altima, Sentra, Versa | Altima and Sentra 2019-2020; Versa 2020-2023 | KR5TXN1 smart key with a DA34 emergency blade | A replacement key has its DA34 blade cut to the car as well as its chip programmed. |
| BMW 3 Series | 2016 manual | Remote with an integrated key for the driver door and glove box | Remote held on the marked spot of the steering column, Start/Stop pressed inside 10 seconds. |
| Mercedes-Benz C-Class | 2015 manual (W205) | SmartKey; the ignition lock takes the SmartKey itself or a Start/Stop button | Starting from the button needs the SmartKey inside the car. |

How the van finds you in Alpharetta: ZIP codes, GA-400 exits and the roads beside them
4Keys Locksmith serves every street address in Alpharetta's four standard ZIP codes, 30004, 30005, 30009 and 30022, all in Fulton County. Some of those addresses carry Milton or Johns Creek as their mailing name, so give the street and number rather than the city. 30023 is a P.O. box ZIP and never the place where the van goes.
GA-400 carries the van north from Brookhaven. Inside Alpharetta, exit 8 is Mansell Road, exit 9 Haynes Bridge Road, exit 10 Old Milton Parkway (SR 120) and exit 11 Windward Parkway. North Point Parkway runs beside the highway on its east side from exit 8 to exit 11, and SR 9 leaves downtown northbound on South Main Street. Say which exit you are nearest and the cross street.
The kind of property shapes the call. In an office park off Windward Parkway, name the building and the suite, and tell front-desk security a locksmith is on the way. In the Avalon decks at GA 400 and Old Milton Parkway, or the lots off North Point Parkway, say which entrance you drove in by and the row. In a gated subdivision, read the access code to dispatch or wait for the van at the gatehouse. For a company with several vans or several doors, a count on the call lets the right stock ride along.
The same dispatch covers Roswell to the southwest and Sandy Springs further down GA-400.
