Norcross, Gwinnett County

From a front door that sticks to a car with no key left

Day or night in Norcross, GA, 4Keys Locksmith sends a mobile locksmith to the address you give; the company holds NASTF VSP authorization for vehicle security work and ALOA certification, carries insurance and a bond, and is registered as 4Keys Locksmith LLC with the Georgia Secretary of State. Nobody waits at a counter, since the company keeps none. Everything rides in the van from Brookhaven, from key cutter and programmer to replacement locksets, and it typically reaches a Norcross address within 15 to 30 minutes of setting out.

The van's work here runs from the house and the business to the car, and one topic gets the full treatment on this page: repairing a lock that sticks, will not latch or fights the key, and recognizing the point where a repair stops making sense and a new lock is the better buy.

No van is sent until you have heard the price on the phone, and the published figures are on the rate list. You can speak Spanish from the first word of the call; the Spanish edition of this page lives at Cerrajero en Norcross.

Home Locks

At the front door in Norcross: opened, repaired, rekeyed or replaced

Houses, townhomes and apartments: the work itself, and what to tell the dispatcher so the right parts are in the van.

Locked out of the house

Getting you back inside is non-destructive work on the lock that is already there. If the key ring is lost for good, not just shut in, the cylinder can get new pins while the technician is with you; say so when you call. Night calls: emergency service.

Repair before replacement

A deadbolt that binds, a latch that misses or a key that turns hard is examined before a new lock is mentioned: the problem may be the strike, the bolt hole or the door rather than the lock. The next section explains what gets checked and fixed.

Rekeying

Only the pins inside change; the knob or deadbolt stays put, and every key cut before today stops working. Want one key for every door? That fits in the same visit. See home locksmith service.

New locks and deadbolts

Hardware that is worn out, broken or forced is replaced with a set that fits the existing bore and backset. A door fitted with nothing but a knob can be given a deadbolt, which means boring the door, mortising a strike into the frame and drilling a bolt hole deep enough for the bolt to extend fully.

Smart locks

Keypad and app locks are installed and coded before the technician leaves. A motorized bolt needs a true strike: Kwikset lists a shallow bolt hole and a strike that does not line up with the bolt among the reasons its motorized deadbolts fail to extend, so alignment is part of the install.

High-security cylinders

Restricted-keyway cylinders whose keys are ordered only against a signed authorization or a similar verification, for an entry door or a freestanding garage where you want to know every copy that exists.
Lock Repair, In Depth

Lock repair: sticking bolts, stray strikes and tired latches

A lock that fights you is not always a bad lock. Schlage's own deadbolt installation guide has you work the bolt twice, first with the door open and then with it closed, and says that if the bolt drags or hits the strike plate with the door closed, the strike or the jamb needs adjusting for better alignment. That comparison is where a repair visit in Norcross starts. If the key and the thumbturn move freely with the door open and only bind once it is shut, the lock body is fine and the trouble lives between the bolt and the frame.

Between the bolt and the frame, three things go wrong. The strike no longer sits where the bolt meets it because the door, the frame or the strike itself has moved; Kwikset names misalignment of any of the three as a reason a deadbolt will not lock. The hole behind the strike is too shallow or packed with debris; Kwikset calls for a bolt hole at least 1 inch (25 mm) deep and clear, so the bolt can extend all the way. Or the latch on the knob or lever below misses its own strike, which Kwikset corrects by adjusting the tab of the lower strike. Its test is simple: retract the deadbolt, close the door, and notice whether you have to push, pull or lift the door to shut it. Each of these is repaired at the door by moving the strike or opening it up, deepening and clearing the bolt hole, or reworking the latch strike.

When the fault is inside the lock, the signs are different. A key that is stiff even with the door open points to the cylinder or to the key itself: try another key to the same lock, and if that one turns freely, a fresh key cut to the lock's depths may be all the repair it needs. A latch that will not spring back, a lever that droops, or a cylinder that turns without moving the bolt points to a worn or broken part inside the lockset. On some models even the mounting screws matter; Kwikset warns that over-tightened screws on its keypad deadbolt can stop it from working.

Repair or replace? A repair is the right call when the lock itself is sound and the problem is alignment, the strike, the bolt hole, loose trim or a worn key. Replacement is the right call when the cylinder is worn past a clean turn, parts inside are broken, the lock was forced, or you wanted a smart lock, a sturdier deadbolt or a restricted keyway anyway. The technician tells you which it is at the door, before starting, and you decide. The same thinking applies to shop and office doors, covered under commercial locksmith service, and a full commercial changeover is laid out in the commercial lock change guide.

At a Sticking Door

What the technician checks before suggesting a new lock

A diagnosis in five parts. It explains the quote you already heard on the phone; it is not a list of things to try with a screwdriver.

  1. 1

    Open door, closed door

    The bolt and the latch are operated open, then shut, by key and by thumbturn. Smooth open and stiff closed means alignment; stiff both ways means the lock or the key.

  2. 2

    The strike and the bolt hole

    Where the bolt meets the strike is marked, the strike opening is compared with the bolt, and the hole behind it is checked for depth and cleared of debris.

  3. 3

    The door in its frame

    Whether the door has to be pushed, pulled or lifted to close, and whether the gap along the latch side is even from top to bottom, shows if the door or the frame has shifted.

  4. 4

    The cylinder and the key

    A second key, the wear on the blade and the feel of the cylinder with the door open separate a tired key from a tired lock.

  5. 5

    Repair or replacement, your choice

    You hear what was found and the options before any part comes off the door: adjust and keep, rekey and keep, or replace.

Auto Locksmith, Norcross

Car keys in Norcross: cut, programmed and fixed at the car

Ford, Chevrolet, Toyota, Honda, Nissan, Hyundai, Kia and Ram up front; German, British and Italian makes go through the same dealer-level access.

Keys shut inside the car

Off Jimmy Carter Boulevard or along Buford Highway, you get back in through non-destructive entry right where the car is parked, using air wedges, reach tools and Lishi picks as needed. Keys locked in the trunk? See trunk lockout. Details: car lockout service. If a child or an animal is shut inside, dial 911 before anything else.

Second key, or a first key from scratch

Got one key that works? It is copied, and the copy's chip is programmed to the car (key duplication). With none, a blade is made from the key code and a fresh key is taught to the immobilizer. First, though, ownership: your title or registration, and a photo ID whose name matches it. Your model year gets checked by the dispatcher while you are on the phone. More: lost car key service and all keys lost.

Programming under NASTF VSP

Transponder keys and smart keys are programmed with dealer-level software under 4Keys' NASTF VSP registration (car key programming); dealer software and locksmiths explains that level of access. Replaced control modules are covered on the Doraville page.

Fobs that quit or came from online

Bought a fob online? Give the dispatcher the frequency, part number and FCC ID printed on the fob or shown in the seller's listing; when they match your car, it gets programmed (fobs bought online). If your own fob simply lost its link to the car, it is linked again; if it has a history of quitting or got soaked, you get a brand-new fob backed by a warranty (which one you have). Buttons died right after a new battery? Read why a fob stops working first; the service page is smart key fob programming.

Ignitions and broken blades

A stiff, stuck or freely spinning key, or a blade that broke off inside a door lock or the ignition, is worked on at the car. Tell the key from the cylinder with key will not turn in the ignition; for a snapped blade, see broken key in the ignition. Services: ignition repair and key extraction.

Vans, pickups and everyday makes

A company with several vans or pickups gets them keyed in a single visit, parked where they are (fleet van keys). Brand-specific detail: the Toyota, Nissan and Honda pages; European and luxury makes go through luxury key programming.
Business Locks

Norcross businesses: key control, rekeys, exits and doors that close right

When a manager or an employee leaves holding a key, each cylinder that key worked gets new pins, and only the people who stay receive the new keys. A list of the doors before the visit keeps the job to one trip; if the building runs on a master system, the change is worked into the existing key chart instead of breaking it.

A master key system gives the owner one key for everything, managers a key for their area and each employee a key to the doors the job needs, all planned on paper before a single cylinder is pinned. Put it on a restricted keyway and duplicates can be ordered only through an authorized channel; planning a master key system goes through the steps. Where metal keys are the problem, card readers, fob readers or keypads on employee entrances let a lost credential be switched off rather than a lock rekeyed, and a system with an audit log shows whose credential opened which door.

Panic bars and other exit devices that jam, stop latching, or need an exterior lever with a keyed cylinder are fixed or exchanged on site. A bar that no longer latches gets the same strike and alignment checks described above before anyone calls it broken. Shop fronts of glass and aluminum along the Buford Highway corridor carry narrow-stile hardware keyed through a mortise cylinder, and that cylinder can be rekeyed or swapped so the storefront matches the back door.

Staff locked out after closing get in at whatever hour they call, and if a key has gone missing the cylinder is rekeyed before the van leaves. Give the dispatcher the business name, the door (front, rear or an interior office) and the hardware on it, and the quote follows on that call.

Finding you in Norcross, and how to describe your spot

4Keys Locksmith covers Norcross ZIP codes 30071, 30092 and 30093 in Gwinnett County. Part of 30092 lies in the City of Peachtree Corners, around Technology Parkway, even though the mail there reads Norcross; the dispatcher routes by street address, whatever city the envelope shows. The city describes Buford Highway as cutting Norcross in two, with its corridor running from Jimmy Carter Boulevard to Beaver Ruin Road, so say which side you are on and the nearest cross street. From I-85, exit 99 (Jimmy Carter Boulevard) and exit 101 (Indian Trail-Lilburn Road) put you in Norcross, and exit 102 is Beaver Ruin Road. At an apartment community, give the building and the unit; at an office park, the suite; at a strip center, the storefront name. The same dispatch covers Duluth up I-85 and Doraville to the southwest.

Fantastic experience! I cannot thank this company enough for their expertise and professionalism. I needed a new key fob programmed for my car, and they handled it swiftly with no delay. They are mobile and that was great. Arrived on time, quality work and pricing was awesome compared to others. I highly recommend this company. Thank you David!

FAQ - Norcross Locksmith Questions, Door to Driveway

Deadbolts that bind, latches that miss, stiff keys, repair or replace, a call in Spanish, Peachtree Corners mail, a shop door at closing time and finding a car near I-85.

The bolt is meeting the strike plate instead of sliding into the hole behind it. Schlage tells owners to test a deadbolt with the door open and then closed, and if it drags or hits the strike with the door closed, the strike or the jamb needs adjusting. Kwikset also asks for a bolt hole at least 1 inch deep and clear of debris. 4Keys repairs that at the door in Norcross by moving or opening up the strike and deepening the hole, and the lock stays.
Not necessarily. On a knob or lever set the latch is its own part, and it can miss its strike when the door or the strike has shifted; Kwikset fixes that by adjusting the tab of the lower strike so the latch bolt enters it. If the latch itself no longer springs out, the latch or the lockset is replaced. The technician checks which one it is before quoting any part.
Try a different key to the same lock. If the second key turns freely, your everyday key has worn down, and cutting a fresh key to the lock solves it. If every key is stiff with the door open, the cylinder is the problem, and it is serviced, rekeyed or swapped, whichever its condition calls for. If the key turns easily with the door open and only binds when it is closed, the problem is alignment rather than the cylinder.
When the cylinder is worn past a clean turn, parts inside are broken, the lock was forced during a break-in, or you are after something it cannot become: a smart lock, a sturdier deadbolt or a restricted keyway. When the lock is sound and the trouble is the strike, the bolt hole, the alignment or a worn key, repairing it keeps hardware that still has years in it. You hear both options before work starts.
Claro que sí. Marcas el mismo número y hablas en español de principio a fin, y en el equipo hay técnicos que hablan español. Te cotizamos en esa misma llamada y la van sale solo cuando aceptas el precio. Si quieres leer antes de llamar, la página Cerrajero en Norcross explica lo mismo en español.
Yes. Part of ZIP 30092, including the area around Technology Parkway, belongs to the City of Peachtree Corners while its mail still reads Norcross. Routing follows the street address you give, so the city on the envelope makes no difference. Add the building number and suite.
A technician comes at any hour. The technician checks whether the strike, the exit device, the latch or the cylinder is at fault and repairs or replaces it so the door locks before you leave. The price is given on the call before the van sets out, and an after-hours surcharge applies between 9 PM and 7 AM local time, and on Sundays and federal holidays, included in that same quote.
Name the exit you used (99 for Jimmy Carter Boulevard, 101 for Indian Trail-Lilburn Road, or 102 for Beaver Ruin Road), which side of the interstate or of Buford Highway you are on, and the business or apartment community whose lot the car is in, plus its color. The work happens in that parking space.
