A mobile locksmith for Lilburn houses, cars and businesses
Around the clock, 4Keys Locksmith sends a mobile locksmith to Lilburn, GA; the business is organized as 4Keys Locksmith LLC on the Georgia Secretary of State's records; it is ALOA-trained, insured by The Hartford, and NASTF VSP authorized for dealer-level car key programming. Every job starts with a phone call, and the dispatcher gives the arrival time from Brookhaven to Lilburn on that call.
No shop or counter sits behind the service. The picks, the extractors, the replacement cylinders and the key programming equipment all ride in the van, so the work happens at your door or beside your car. The dispatcher quotes the job before anyone drives over, with the after-hours surcharge counted in for calls between 9 PM and 7 AM local time, and on Sundays and federal holidays, and the rates we publish are on our pricing page. We have Spanish-speaking technicians, so the problem can be explained in English or in Spanish.
Three details make the first call short. Say what is on the door: a knob with a keyhole, a lever, a separate deadbolt, or a keypad. Say what happened to the key: shut inside, lost, bent, or snapped with a piece still in the lock. And say how many doors lead into the house, because a missing key turns an opening into a rekey of each of them.

Getting into a locked house, or past a key snapped in the door: what the technician does and when the cylinder is replaced
Most house door locks are pin tumbler locks. The key slides into a plug that sits inside a housing; above each cut of the key rests a key pin, and above that a spring-loaded driver pin. Only the right key lifts every pair so the gap between them lands exactly on the shear line, the seam between plug and housing, and only then does the plug turn to throw the bolt or retract the latch. A lockout and a broken key are both problems at that seam, which is why the first move is to work the lock's own parts rather than force the door.
Getting you back in starts with non-destructive entry. Lock picking, opening a lock by moving its pins with a tension wrench and picks instead of a key, is the textbook example and a core skill of the legitimate locksmith trade; the technician chooses among picks and other entry tools according to the lock on your door. When the lock opens this way it keeps working and your keys still fit. If the key went missing instead of being locked in, rekeying the cylinder on that same trip leaves the lost key useless.
A key that snaps leaves part of its blade inside the keyway, and where the plug stopped decides how hard that part comes out. With the plug at rest, the position in which a key slides in and out, the key pins are free to rise and the fragment can be drawn out with a broken-key extractor. If the plug was turned when the key broke, the housing holds those pins down in the cuts of the blade and they grip the piece, so the plug has to be brought back to rest before anything will move. Until the technician arrives, leave the keyway alone: do not push the piece deeper, and do not work at it with a second key. Once the fragment is out, a fresh key is cut to fit that lock, and bringing the broken head along lets the technician read the cuts from both halves.
The cylinder is replaced, not saved, in a few clear cases. If the plug will not turn with a good key once the piece is out, or it turns and the bolt stays put, the cylinder or the parts behind it have been damaged. If a lock cannot be opened by manipulation, 4Keys treats drilling as the last resort; it destroys the cylinder, so a new one is fitted during that visit, and the technician explains why before drilling starts. Which part gets replaced depends on the lock's format: the cylinder inside a knob or lever, the cylinder of a deadbolt, a rim cylinder behind a surface lock, or a threaded mortise cylinder. The replacement goes into the door's existing preparation and can be keyed to match your other doors. A lock that sticks or will not latch for reasons other than a broken key is a repair question, covered on the Norcross page.
Before a house door is opened, the technician confirms that the person asking lives there; the dispatcher explains on the call which papers serve for that. It protects you as much as anyone, since the same check keeps a stranger from being let into your home.

Where in Lilburn the van goes, and how to point the technician to you
Lilburn has two ZIP codes: 30047 carries every street address, and 30048 is for post office boxes only. Give the dispatcher a 30047 street address, or the name of the business or the apartment community.
Lawrenceville Highway (US-29) runs through the middle of town and continues 11 miles northeast to Lawrenceville. Beaver Ruin Road (SR-378) leaves I-85 at exit 102 and ends at Lawrenceville Highway in Lilburn, so drivers coming from the Norcross side arrive that way. Rockbridge Road meets Lawrenceville Highway southwest of the town center. On any of these, name the nearest cross street. In Old Town, the lot at Lilburn City Park, on the corner of Main Street and Railroad Avenue, is an easy place to meet the van.
Lilburn is largely a city of detached houses, so a rekey here tends to cover several exterior doors: front, back, side and the one from the garage. Count them before you call, and mention any lock that is stiff or loose, since a tired cylinder can be exchanged while the others are repinned. At an apartment community with a gate, give the code or meet the technician at the entrance.
