A Roswell locksmith that works out of a van, not a storefront
4Keys Locksmith is a mobile locksmith serving Roswell, GA around the clock: insured and bonded, ALOA certified, NASTF VSP authorized, and on file with the Georgia Secretary of State as a limited liability company, 4Keys Locksmith LLC. Cutting, programming and lock hardware all ride in the van to wherever the problem is, because we keep no storefront for you to drive to, and a van dispatched from Brookhaven typically gets to Roswell in 15 to 30 minutes.
Roswell calls cover the whole trade: ignitions that bind or spin, keys that are lost or worn thin, remotes and push-button smart keys, cars locked with the keys inside, front doors that need new keys, and offices that need a master key or a new exit device. The ignition lock cylinder gets the long explanation below, because it is the car job where a wrong guess costs the most: a new key bought when the cylinder was the fault, or a new cylinder bought when the key was.
Each job gets its price over the phone, and no van rolls until you accept it; see what 4Keys publishes as rates. The call itself can run in English or in Spanish.
Repair the ignition cylinder, replace it, or cut a new key: how the decision gets made
An ignition lock cylinder is a small lock in its own right. Its plug holds a stack of flat, spring-loaded wafer tumblers, and the cuts on the key blade raise each wafer to the shear line so the plug can rotate through Accessory, On and Start. Some designs add a sidebar that only retracts once every wafer sits level. Behind the plug, a cam or actuator passes that rotation to the ignition switch, the electrical part that tells the car to crank. Blade, wafers or switch: each fails differently and takes a different repair.
A worn key is the fault people overlook, because it still looks normal. The cuts lose depth start after start until one day the blade enters fully but will not lift the wafers far enough, so the plug stops halfway or turns only when you jiggle it. The fix is a new key cut to the factory code tied to the VIN, or to depths read from the cylinder itself, then programmed to the immobilizer so the transponder is recognized. A copy of the tired key repeats the tired cuts, which is why a duplicate made from it fails the same way. The spare-key test that separates a worn key from a worn cylinder is laid out in our guide for a key that refuses to turn.
When the spare binds exactly like the everyday key, the wafers or their springs have given out, and that cylinder is replaced rather than coaxed. A replacement is keyed to the key you already carry where its design allows it, so the key and its chip keep working. Where it arrives coded differently, a new key is cut to the new cylinder and programmed during that visit. That is the plain answer to when an ignition job needs a new key: the cylinder code changed, the old blade is too worn to decode, or the key snapped inside the plug, which starts with broken key extraction.
Some stuck ignitions never need a cylinder at all. A steering column lock loaded against its pin, a shifter not fully in Park, or a fragment of blade lodged in the keyway all leave a sound cylinder once they are cleared. A key that turns with no resistance and cranks nothing points past the cylinder, to the actuator or the switch, which the key-spins guide explains. The technician checks key, plug and linkage before any part is quoted, and all of it is done where the car sits: ignition repair at the car.
Push-button cars have no wafer cylinder to wear, so a no-start on one is a question of the fob, the steering lock or a module, and some Mercedes-Benz models turn the SmartKey in an electronic ignition lock with no tumblers at all. And before paying for any cylinder, run the VIN for an open ignition recall: a recall repair belongs to the manufacturer, done by its dealer at no charge. The campaigns below come from the NHTSA record; Accord and Pilot owners can read more on our Honda locksmith page, and GM truck owners on the Chevrolet and GMC pages.
Ignition campaigns to check by VIN before a cylinder is bought
Campaign numbers, models and years as the NHTSA recall database prints them. Where a campaign covers narrow build dates, only some VINs in those years are included.

My Honda Accord was stranded in Roswell with an ignition issue. Juan came right over and fixed my ignition for a low price. There was an issue that popped up and he even came through to my house to fix that! Thanks for the new key as well!
4Keys responded to my request and was able to come render my service very fast. David was very professional and knowledgeable. I would highly recommend 4Keys Locksmith for all your locksmith needs.

Finding the van in Roswell: ZIP codes, GA-400 and the state routes
4Keys Locksmith covers every street address in Roswell's two standard ZIP codes, 30075 and 30076, all in Fulton County. The third Roswell ZIP, 30077, is for post office boxes, so the dispatcher needs the street address where the car or door actually is. The Chattahoochee River marks the city's southern edge.
From GA-400, exit 7 is Holcomb Bridge Road (SR 140), signed 7A east and 7B west northbound and simply Roswell southbound. SR 9 crosses the city as Atlanta Street or Alpharetta Street and becomes Alpharetta Highway from downtown, sharing its path with SR 120 for a stretch, and SR 92 and SR 140 also serve Roswell. On any of them, name the nearest cross street and which side of the road you are on.
Where the car or door is changes the call. At a gated apartment community, pass along the access code, or walk out and wave the technician in. In the parking deck at Wellstar North Fulton Medical Center on Hospital Boulevard, name the floor and the nearest pillar or row letter; the technician works on the car right where it stands. At the river lots along Riverside Road, say which lot and which end of it. For an older house, a picture of the lock texted ahead lets the dispatcher load the right cylinder or rekey kit. For an office with card readers or a yard of work vans, say how many doors or vehicles there are.
The same dispatch reaches Alpharetta to the northeast and Sandy Springs across the river to the south.
