Standard Key Blanks

Shop standard key blanks for residential, commercial, institutional, padlock, cabinet, mailbox, and utility-lock applications. Noble Key Supply carries popular keyways in brass and nickel-plated finishes, with individual blanks and bulk quantities available.

The collection includes mechanical key blanks from ESP, JMA, Paladin, and other trusted key manufacturers. Available keyways cover widely used Kwikset, Schlage, Yale, Master Lock, Best, National, Corbin, and specialty applications.

Compare the complete key number, keyway, blade length, groove pattern, and cross-reference information before cutting a replacement.

What Is a Standard Key Blank?

A standard key blank is an uncut mechanical key without an electronic transponder or remote. Its blade contains the grooves needed to enter a compatible keyway, but the edge has not yet been cut to operate a specific lock.

After selecting the correct blank, a locksmith can duplicate an existing key or originate a new key from an authorized code or lock-decoding procedure.

Standard keys are commonly used for:

• Residential deadbolts
• Entry knobs and levers
• Commercial door locks
• Padlocks
• Mailboxes
• Cabinets
• File cabinets
• Utility locks
• Storefront hardware
• Institutional locks
• Older vehicle locks
• Equipment and machinery

The blank must match the lock’s keyway before it can be cut.

Residential Key Blanks

Residential locks commonly use Kwikset, Schlage, Yale, and other manufacturer-specific keyways. Two keys can have similar blade lengths while using different groove patterns that prevent them from entering the same lock.

Common residential blanks in the collection include:

• KW1
• KW10
• SC1
• SC4
• SC8
• SC9
• Y1
• Y2
• Y11
• Y13
• Y14
• Y52

Verify the original key number whenever possible. If the original marking is unavailable, compare the keyway profile with a reliable reference before selecting the blank.

Kwikset Key Blanks

Kwikset keyways are widely used in residential locks throughout the United States. The collection includes common Kwikset blanks such as KW1 and KW10.

KW1 Key Blanks

KW1 is a popular five-pin Kwikset key blank. It may cross-reference to numbers such as:

• ESP KW1
• Ilco 1176
• Axxess 66
• Curtis KW-1
• Cole KW1
• JMA KWI-1D

KW1 blanks are available in brass and nickel-plated versions, with individual and bulk quantities represented in the collection.

KW10 Key Blanks

KW10 is commonly associated with compatible six-pin Kwikset keyways. It may cross-reference to Ilco A1176ST and other manufacturer numbers.

KW1 and KW10 should not be treated as interchangeable. Confirm the blade length and pin count before duplication.

Schlage Key Blanks

Schlage keyways are frequently found in residential, commercial, and institutional hardware. Available blanks include several members of the SC family.

SC1 Key Blanks

SC1 is a common five-pin Schlage C keyway blank. Cross-references may include:

• ESP SC1
• Ilco 1145
• Axxess 68
• Curtis SC-1
• Cole SC1
• JMA SCH-1D

SC1 blanks are available individually and in boxes for locksmiths who duplicate this keyway regularly.

SC4 Key Blanks

SC4 is a longer six-pin version associated with compatible Schlage C keyway cylinders. It may cross-reference to Ilco 1145A.

Confirm whether the cylinder is pinned for five or six positions before choosing between SC1 and SC4.

Additional Schlage Blanks

The collection also includes other Schlage key numbers, such as SC8 and SC9, for compatible lock systems. These blanks have different keyway profiles and should be matched precisely with the original key or cylinder.

Yale Key Blanks

Yale locks use a wide selection of keyways across residential, commercial, cabinet, and specialty applications.

Yale key blanks represented in the collection include:

• Y1
• Y2
• Y11
• Y13
• Y14
• Y52

Each number identifies a distinct blade and groove configuration. For example, Y1 may cross-reference to Ilco 999, while Y2 may cross-reference to Ilco 999A.

Do not rely on the Yale name alone. Match the complete blank number and physical profile.

Master Lock Key Blanks

Master Lock padlocks and related products use multiple keyways. Available key blanks include M-series options such as:

• M1
• M2
• M4
• M11

M1 may cross-reference to Ilco 1092, while other M-series keys use different profiles and reference numbers.

The padlock model, original key, and keyway should all be checked before selecting a blank.

Best Key Blanks

Best interchangeable-core and commercial lock systems use keyways that differ from common residential blanks. The BE2 blank represented in the collection may cross-reference to Ilco A1114A and other manufacturer numbers.

Interchangeable-core systems may also involve restricted, patented, or facility-specific keyways. Verify that the blank is appropriate and that the customer is authorized to request duplication.

National and Cabinet Key Blanks

Cabinet, desk, file, and utility locks often use compact key blanks with profiles different from standard door keys.

National and related key blanks in the collection include examples such as:

• NA12
• NA14
• NA15
• RO1
• CO106
• IN8

RO1 is associated with compatible National Rockford cabinet locks and may cross-reference to Ilco 1069. NA12 and NA14 use different blade configurations despite their similar names.

Match the lock code, original blank number, and keyway profile before cutting.

Brass Key Blanks

Brass is a traditional material for mechanical key blanks. It provides a useful balance of strength and machinability, allowing a properly adjusted key machine to produce clean cuts.

Benefits of brass blanks include:

• Smooth cutting
• Easy deburring
• Clear impressioning marks
• Compatibility with common duplication machines
• Traditional gold-colored appearance

A brass key should be inspected after cutting for burrs, sharp edges, and incomplete cuts.

Nickel-Plated Key Blanks

Nickel-plated blanks use a base material covered with a silver-colored finish. The plating can help resist surface tarnish and provides a familiar appearance for retail key duplication.

Popular blanks such as KW1, SC1, and SC4 may be available in nickel-plated versions.

The finish does not change the keyway. A nickel-plated SC1 and a brass SC1 should fit the same compatible keyway when both are manufactured and cut correctly.

Individual Key Blanks

Individual blanks allow locksmiths to purchase less frequently used keyways without committing to a full box. They are useful for:

• Testing a new product line
• Replacing low-volume inventory
• Servicing an uncommon lock
• Completing a specific customer job
• Building a reference collection

Check the product description to determine whether the listed price is for one key or a box.

Bulk Key Blanks

High-volume keyways are available in box quantities. Depending on the product, packages may include 50, 250, or another specified number of blanks.

Bulk purchasing is practical for locksmiths, hardware stores, property managers, and facilities that regularly duplicate common keys such as KW1, SC1, and SC4.

Store bulk blanks by key number and finish to prevent similar profiles from becoming mixed.

ESP Key Blanks

ESP represents most of the standard key inventory in this collection. Its catalog covers widely used residential, commercial, cabinet, padlock, and specialty keyways.

ESP product descriptions may provide multiple cross-references from manufacturers such as:

• Axxess
• Borkey
• CEA
• Cole
• Curtis
• Dominion
• Ilco
• Ilco EZ
• Jet
• JMA
• Original equipment manufacturers
• Silca

Cross-references make it easier to locate an equivalent blank when different shops use different catalog systems.

JMA and Paladin Mechanical Keys

Select JMA and Paladin products are also included in the collection. Brand selection may depend on keyway availability, material, finish, head design, or the locksmith’s preferred cutting inventory.

Regardless of brand, confirm the blank’s complete specifications. Equivalent catalog references should still be compared before cutting a high-value or uncommon key.

Understanding Key-Blank Cross-References

The same mechanical key blank may be identified by several numbers because manufacturers maintain separate naming systems.

For example, one common keyway might be listed under an ESP number, Ilco number, JMA reference, Curtis number, and hardware-store number.

When using a cross-reference:

1. Confirm the primary keyway.
2. Compare the blade length.
3. Check the shoulder or tip-stop design.
4. Verify the groove pattern.
5. Compare the bow and overall dimensions.
6. Confirm whether the blank is standard or extended length.
7. Check the intended lock manufacturer.

Cross-reference information is useful, but direct comparison with the original key remains important.

“Do Not Duplicate” Key Blanks

The collection includes select blanks stamped “DO NOT DUPLICATE,” including compatible SC1 configurations. These markings can help a property owner communicate an internal duplication policy.

A “DO NOT DUPLICATE” stamp alone does not necessarily make a key legally restricted or technically impossible to copy. Locksmiths should follow applicable laws, professional standards, customer-verification procedures, and contractual key-control policies.

For stronger duplication control, consider patented or restricted key systems with controlled blank distribution and documented authorization requirements.

Metal Key Heads

Traditional all-metal keys have a thin, durable bow that fits easily on a key ring. The bow may include stamped numbers identifying the manufacturer or keyway.

Advantages include:

• Compact profile
• Easy labeling
• Simple bulk storage
• Compatibility with common duplication equipment
• Familiar handling for customers

The bow shape can assist with identification, but the blade profile remains the determining compatibility factor.

Mechanical Keys vs. Transponder Keys

A standard mechanical key contains no immobilizer chip. It can operate a compatible mechanical lock but cannot replace a transponder key when the vehicle requires electronic authentication.

Before cutting an automotive-style mechanical blank, determine whether the customer needs:

• A door-only key
• A non-transponder ignition key
• A transponder key
• An emergency insert blade
• A remote head key
• A proximity smart key

A mechanical blank may provide door access without starting a chip-equipped vehicle.

Keys for Mailboxes and Cabinets

Mailbox and cabinet keys are identified through the original key, lock manufacturer, lock code, or keyway profile. Similar cabinet blanks may differ in groove placement, shoulder position, length, or tip geometry.

Before duplicating or originating a key, confirm:

• Lock brand
• Code series
• Original blank number
• Shoulder or tip-stop position
• Keyway orientation
• Customer authorization

Replace worn locks when a correctly cut key cannot operate reliably because of internal damage.

Keys for Padlocks

Padlocks use manufacturer- and model-specific keyways. Even products from the same brand may require different blanks.

Confirm the padlock model or original key reference before choosing an M-series or other padlock blank. If the lock is part of a keyed-alike group or master-key system, maintain the appropriate records and pinning specifications.

Cutting Standard Keys

Standard edge-cut keys can be duplicated from an existing key or originated using an authorized code.

A professional cutting process generally includes:

1. Identifying the correct blank
2. Inspecting the original key
3. Checking jaw alignment
4. Securing both keys correctly
5. Making controlled cuts
6. Deburring the new key
7. Comparing the duplicate with the original
8. Testing the key in the lock

A worn original may produce a poor duplicate if its wear is copied directly. In those situations, a locksmith may decode the intended depths or originate the key to specification.

Key-Machine Setup and Maintenance

Accurate duplication depends on a properly adjusted key machine. The tracer, cutter, jaws, and spacing must remain aligned.

Routine maintenance may include:

• Cleaning the jaws
• Removing metal shavings
• Checking cutter condition
• Confirming calibration
• Inspecting belts and moving parts
• Lubricating the machine as directed
• Replacing worn cutters
• Verifying depth and spacing with test keys

A high-quality blank cannot compensate for a poorly calibrated machine.

How to Select the Correct Standard Key Blank

Before ordering or cutting, verify:

1. Key manufacturer
2. Keyway or blank number
3. Cross-reference number
4. Blade length
5. Groove pattern
6. Shoulder or tip-stop design
7. Number of pin positions
8. Brass or nickel-plated finish
9. Single or bulk quantity
10. Lock type
11. Residential, commercial, cabinet, or padlock application
12. Authorization requirements

Do not force a similar blank into a lock. An incorrect groove pattern can damage the blank or keyway.

Organizing a Locksmith Key-Blank Inventory

Arrange key blanks so technicians can identify them quickly and avoid mixing similar profiles.

Useful organization methods include:

• Numbered hooks
• Labeled bins
• Manufacturer groups
• Separate brass and nickel-plated stock
• Dedicated sections for residential and commercial keys
• Low-stock indicators
• Cross-reference charts
• Sample keys for visual comparison

Place high-volume blanks such as KW1, SC1, and SC4 in accessible locations while keeping less common keys clearly labeled.
