North Miami, Miami-Dade County

A key just snapped? Stop turning it, hold on to both pieces, and call.

4Keys Locksmith is a mobile locksmith in North Miami, FL, available 24 hours a day, that extracts broken keys from car ignitions, car doors and house locks and cuts and programs the replacement at the vehicle; it is NASTF VSP authorized, ALOA certified, insured and bonded, and operated by Qorinca LLC under Miami-Dade County locksmith license LK-094576. There is no storefront: the extraction tools, the key machine and the programming equipment are in the van, which typically reaches North Miami in 15 to 30 minutes, and the dispatcher gives you the time on the call.

The first minute decides how big the job gets. Take your hand off the key and do not try to turn the lock with what is left in it. Keep the half in your hand exactly as it is, and do not push anything into the keyway: no glue, no spray, no paperclip. If the piece in the lock sticks out past its face, one straight pull with no twist is a fair try; if it sits flush or deeper, leave it for the technician.

When you call, say where the key broke (ignition, a door, the trunk, a house or office door), the year, make and model or the type of lock, and whether a spare exists. The price is given on that call, before a van is sent; published reference rates live on the 4Keys pricing page. Calls are answered in English and Spanish, and the full service is at broken key extraction.

Broken Key Extraction

Where the blade broke changes the job: ignition, car door, trunk or the front door

The extraction itself is the same idea everywhere: thin tools down the keyway beside the fragment, with the aim of leaving the lock working. What surrounds it is not.

Snapped in the ignition

The most involved case. The ignition lock cylinder holds the steering column lock and, behind it, the switch that starts the car, so forcing the plug with a fragment inside can shear a wafer and turn an extraction into a cylinder replacement plus a programmed key. Do not try to start the car. Background: a key broken in the ignition.

Snapped in a car door

The door lock cylinder is a separate, smaller part connected to the latch by a rod, and it can be reached without touching the ignition. If a spare key or a fob exists, the car still drives while you wait; say so on the call. If the door is the only way in, the car is opened first.

Trunk, hatch or glove box

These cylinders use the same wafer design as the door and come apart from the same kind of work. A blade broken in the trunk lock with nothing else wrong is a short visit; a trunk that also holds the keys is a trunk lockout as well.

Snapped in a house or office lock

House and office cylinders are pin-tumbler locks rather than wafer locks, but the rule is the same: extract first, then decide. If the cylinder is healthy, a new key is cut and you keep the lock; if the break came from a worn or failing cylinder, it is rekeyed or replaced in the same visit.

What not to put in the keyway

Super glue on a matchstick wicks past the fragment and bonds it to the wafers and the plug. WD-40 and penetrating oil are solvents and water displacers, not lock lubricants: they make the fragment slippery for the extractor and later collect grit in the wafer stack. A healthy lock takes a dry PTFE lubricant or a little graphite, and neither one removes a broken key.

When the cylinder has to come out

Three things push the job past extraction: a wafer sheared by turning the plug, a fragment glued in place, or a piece driven so deep by tweezers or pliers that no tool can hook a cut. Then the cylinder is replaced, and on an ignition a new key is programmed to match. The Hollywood page covers ignition cylinders in depth.
The Half You Kept

Cutting a new key from a broken one: what each piece still carries

A car key that breaks in two does not lose everything at once. Its two halves carry two different kinds of information, and each one can save part of the job. That is why the advice to keep both pieces is more than tidiness.

The bow carries the chip. The plastic head of a transponder key holds the chip the immobilizer reads before it lets the engine run. A clean break across the blade leaves that chip alone, so the head that stayed in your hand may still be recognized by the car. Depending on the key system, a working chip can be read and copied onto a new key, or a new chip is programmed while the old one stays registered; the difference between those two routes is explained on the Pembroke Pines page. Either way, a surviving bow is good news, and it is no reason to throw the head away.

The blade carries the cuts. A key blade is a pattern of depths at fixed spaces, called the bitting, measured from the shoulder, the small step where the blade meets the head. When the stub in your hand still has its shoulder and the fragment drawn from the lock carries the rest, the two are laid side by side and the full pattern is read off them, so a new blank can be cut to the same bitting. Edge-cut keys and laser-cut (sidewinder) keys are both read this way; only the machine set-up differs.

When the pieces are not enough. If the key broke right at the shoulder, or the stub was bent, filed or glued, there is no reliable reference to measure from. There are two other ways to the cuts. The cylinder can be decoded: a Lishi 2-in-1 tool cut for that keyway feels each wafer and translates its height into a cut depth. Or the key code is pulled from the VIN through NASTF, which releases key codes and immobilizer data to technicians registered as Vehicle Security Professionals; 4Keys holds NASTF VSP authorization. The documents the case requires are requested on the call. If no key at all is left afterward, the job becomes the all-keys-lost route set out on the Hialeah page.

Why keys snap in the first place. A brass or nickel-silver blade work-hardens with years of turning and grows brittle at the shoulder. Meanwhile the wafers inside an old cylinder wear, so the key needs more and more twist to turn, and one day the metal gives before the lock does. Using a key to pry, cut tape or open boxes speeds that up. A bent key is close behind: straightening it bends the metal a second time at the same spot, so it is weaker afterward, not stronger. A key that has started to drag in the ignition is the warning: a new key cut by code, or a look at the cylinder, is cheaper than an extraction. See a key that will not turn for that symptom.

When the Technician Arrives

A broken key visit in North Miami, from the first look to the key that works

What you will see happen at the car or the door, so you know what a careful job looks like.

  1. 1

    A look before any tool goes in

    The technician checks where the fragment sits (proud of the face, flush or recessed), whether anything was sprayed or glued into the keyway, and whether the plug was turned with the piece inside. That decides the tool and tells you up front whether the cylinder is at risk.

  2. 2

    The fragment comes out with the plug at rest

    A thin extractor shaped for the gap, a spiral, a barbed hook or a double hook, goes in beside the blade and draws the piece straight out. On an ignition, nothing is turned until the keyway is clear.

  3. 3

    The cuts are recovered

    The two halves are matched and the bitting read from them. If they are incomplete, the cylinder is decoded or the key code is pulled by VIN instead, and the dispatcher will already have told you which route applies.

  4. 4

    A new key is cut and tried in the lock

    The new blade is cut in the van and tried in the lock it came out of, then in the other locks it should open, the doors and the trunk on a car or the other doors in a house.

  5. 5

    The chip is handled, and the lock is checked

    On a transponder key, the chip is copied or a new one programmed so the engine starts. The cylinder is also checked for smooth travel; a lock that drags is the one that breaks the next key, and the technician tells you so rather than leaving it for later.

Car Locksmith Service

The rest of the car work in North Miami, done in the driveway or the garage

Locked out. A car with its keys sealed inside is opened through the door seam or at the lock with purpose-made entry tools, and a slim jim never goes near a modern door; the Miami Gardens page explains why in detail. Service: car lockout.

Spare keys and lost keys. Having a second key made while one still works is the cheapest protection against ever needing this page again: it is cut and its chip set up beside the car (car key duplication). When nothing is left to copy, the job grows: a code-cut blade plus a fresh chip taught to the immobilizer, priced above a duplicate, and on the first call the dispatcher tells you how your model year is done (lost car key replacement).

Fobs and smart keys. Push-button proximity fobs, flip keys and keys with buttons in the head are all set up at the vehicle. If you ordered one online, read the dispatcher its FCC ID, frequency and part number; when those match the car, it gets programmed (programming a fob bought online). A healthy fob that simply forgot the car is paired again, and a fob that has failed repeatedly is swapped for a new one carrying the 4Keys warranty (deprogrammed or broken fob). Trouble that started right after a battery swap has its own guide: key fob not working.

Ignitions, modules, fleets and European models. At the car, the technician sorts out whether a sticking or free-spinning key is the key's fault or the cylinder's (ignition repair). When a shop has installed a new body control module, engine computer or immobilizer module, it is matched to the car with dealer-level software, reached under the NASTF VSP credential (ECU and module programming). Company vans and pickups get their keys at the yard, many units per trip (fleet van key programming). German and British keys, BMW, Mercedes-Benz, Audi, Volkswagen, Land Rover, are part of the same work, which spans American, German, Japanese, Korean, British and Italian makes (luxury key programming).

Residential Locksmith

Houses, condos and apartments: getting in, and deciding who has a key

From single-family streets to bayfront buildings with a front desk. What each job is and what the dispatcher needs to hear.

Locked out of the house

The technician starts on the lock already on the door and drills only when nothing else will move it. Behind a front desk or a guarded gate, explain on the call how the van gets to your unit. More at residential locksmith service.

Rekey

New pin stacks inside the cylinders retire every old key while the handles and deadbolts stay put, and the front, back and garage doors can share one new key. Which doors come first after a purchase is on the Miami Shores page.

Lock change or a new deadbolt

Hardware that is loose, corroded or broken gets replaced with a lock sized to the holes already in the door. A door with no deadbolt can take one, which means new holes in the door and a strike in the frame; mention it when you call.

Smart locks

A keypad or phone-controlled deadbolt can replace a keyed one, and the technician programs the user codes before leaving. You can buy the unit yourself or ask for one to be brought.

High-security cylinders

A patented, restricted key cannot be duplicated at a kiosk or a hardware store, so you decide who gets copies. Worth it on a home that has had many keyholders over the years.

Condo unit doors

A unit lock can sit under a building master. Say whether your building has one, because it changes how the cylinder is rekeyed. Shared doors run by an association are covered on the Surfside page.
Commercial Locksmith

Shops and offices on Biscayne Boulevard and NE 125th Street: the locks a business depends on

Rekeys after staff turnover. A key that left with a former employee is closed out by rekeying every door it worked, then handing fresh keys to the team that remains. Bring a list of doors and keyholders to the call; a building that runs on a master system is redone against its existing chart. Service: commercial locksmith service.

Master keys and access control. A layered key system lets the owner open every door while a clerk opens only the front and the stockroom, and a restricted keyway keeps those keys from multiplying; planning is covered in the master key system setup guide. Where handing out metal keys has become the problem, a keypad or a card reader replaces them, a lost card is cancelled instead of rekeying, and some systems record each entry.

Exit devices and storefronts. A rear exit with a panic bar has to release from inside with a single push and still hold from the street side; bars that drag, fail to catch or lack an outside cylinder are fitted, tuned or replaced. Glass-and-aluminum shop fronts use slim hardware made for their narrow frames, from the hook-shaped deadbolt to the threaded mortise cylinder, and a worn door closer can be the reason such a door stops locking. A snapped key in a shop cylinder comes out with the same extractors used on a car, and a call from an owner shut out after hours is answered day or night.

Service Area

Finding you in North Miami: ZIPs, I-95 exits and gates

4Keys Locksmith covers North Miami from NE 163rd Street south to 119th Street and from NW 17th Avenue east to the bay, on both sides of I-95. The ZIP codes are 33161 and 33181, which carry the North Miami postal name, and 33167 and 33168, which reach parts of the city under the Miami name. Give the street address and the ZIP.

From I-95, exit 10A puts you on NW 125th Street (SR 922), which runs east through the city; exit 10B joins NW 135th Street. Biscayne Boulevard runs along the east side, between the interstate and the bay. On either, name the nearest cross street and which side of the road the car is on.

Gates and front desks change the approach. Keystone Point and Sans Souci are gated, so give the gate or guard instructions on the call or meet the van at the entrance. A condo or apartment building with a concierge needs the technician's name left at the desk, and a car in a building garage is worked on in its space once the level and the spot are known. Near the commercial corridors, say whether the car is on the street, in a strip-center lot or behind a building, and give a storefront name to walk toward rather than a landmark. On single-family streets there is nothing to clear: a key snapped in the car and a sticky front-door cylinder can share one visit. The same dispatch covers North Miami Beach to the north, Miami Shores to the south and Opa-locka to the west.

FAQ - Broken Key Questions from North Miami

What to do in the first minute, getting the piece out without hurting the cylinder, cutting a key from the halves, the chip, glue and WD-40, driving with a broken key, price and night hours.

Stop turning, do not try to start the car, and leave the fragment where it is unless it clearly sticks out past the face of the lock, in which case one straight pull with no twist is a fair attempt. Keep the half you are holding exactly as it is. Then call 4Keys Locksmith with the year, make and model; a technician is dispatched in Miami-Dade to North Miami, typically in 15 to 30 minutes.
It can be, when the fragment has not been forced. Thin extractors, spiral, barbed hook or double hook, go down the keyway beside the blade, catch a cut or the tip and draw it straight out while the wafers stay at rest, with the plug left unturned. The cylinder has to be replaced when a wafer was sheared, the piece was glued, or an earlier attempt pushed it beyond reach.
Bring both. The cut pattern is measured from the shoulder of the blade, so the half with the shoulder plus the piece drawn from the lock together give the full bitting, and a new key is cut to it. If the key broke at the shoulder or a piece is lost or damaged, the cuts are recovered by decoding the cylinder or from the key code tied to the VIN.
Very possibly. The chip lives in the plastic head, not in the blade, so a clean break across the blade leaves it intact. Depending on the system, the chip in your old head can be read or the new key is programmed to the car alongside it. Do not throw the head away until the technician has looked at it.
No, and both make the job harder. Glue runs past the fragment and bonds it to the wafers and the plug, which can turn a short extraction into a cylinder replacement. WD-40 and penetrating oil are solvents, not lock lubricants: they make the fragment slippery for the extractor and later trap grit in the cylinder. If you already sprayed something in, tell the technician so the keyway is cleaned first.
Yes. The door cylinder is a separate part tied to the latch by a rod, so the ignition and the steering column lock are not involved, and if a spare or a fob exists the car can still be driven. Extraction from a door is a simpler job; the cylinder can be rekeyed or replaced separately if the break damaged it.
Do not try. Turning the plug with part of a blade inside can shear wafers and leave the steering column locked. Leave the car where it is, or if it is already running and somewhere unsafe, move it only to the nearest safe spot and tell the dispatcher the engine is running. Once the fragment is out, the ignition is checked before anyone drives.
Two kinds of wear meet. The metal blade work-hardens and turns brittle at the shoulder after years of use, while the wafers in an old cylinder wear and demand more twist to turn. Using the key as a tool adds stress. A key that has started to drag is a sign to get a new key cut by code or the cylinder looked at before it breaks.
Not necessarily. The piece is extracted first, and if the cylinder turns smoothly afterward, a new key is cut from the halves and the lock stays. If the cylinder was worn enough to snap the key, it is rekeyed or replaced in the same visit, and you can take the chance to rekey the other doors to the same key.
The dispatcher quotes it on the phone before a van leaves, depending on where the key broke, whether a new key has to be cut and programmed, and whether the cylinder is damaged. An after-hours surcharge applies between 9 PM and 7 AM local time, and on Sundays and federal holidays, and it is already in the price you are given on that call. Reference rates are on the 4Keys pricing page.
