Automotive Mechanical Keys & Key Blanks

Shop automotive mechanical keys for professional locksmith work, duplicate-key services, vehicle-entry testing, and inventory restocking. Noble Key Supply carries non-transponder car keys, plastic-head keys, mechanical test keys, and key shells with chip holders for numerous vehicle applications.

The collection includes individual products and multipacks from JMA, ESP, Paladin, OEM, and other aftermarket brands. Verify the keyway, blade profile, cross-reference number, and intended application before ordering or cutting a key.

Non-Transponder Car Keys

Mechanical car keys operate the vehicle’s lock or ignition through the physical blade. Unlike transponder keys, standard mechanical keys do not contain an electronic chip that communicates with the immobilizer.

Depending on the vehicle, a mechanical key may be used for:

• Older vehicles without an immobilizer
• Door or trunk access
• Test-key applications
• Emergency entry
• Duplicate-key services
• Identifying an unknown keyway
• Creating a key shell with a separately installed chip

A mechanical key alone will not start a chip-equipped vehicle unless the required transponder is also present and properly programmed.

Automotive Key Blanks for Multiple Manufacturers

The collection contains mechanical key blanks and shells for domestic, Asian, and European vehicle applications. Available keyways may support compatible vehicles from manufacturers such as:

• Chevrolet, Buick, GMC, and Cadillac
• Ford, Lincoln, and Mercury
• Dodge, Chrysler, Jeep, and Ram
• Toyota, Lexus, and Scion
• Honda and Acura
• Nissan and Infiniti
• Hyundai and Kia
• Volkswagen and Audi
• Mazda and Mitsubishi

Compatibility varies by model and year. Always use the listed keyway and cross-reference information rather than selecting a blank based only on the vehicle manufacturer.

Common Automotive Keyways

Mechanical automotive keys are identified by keyway numbers and industry cross-references. Examples represented within this collection include:

• TR47 and TOY43
• HU100
• HU101 and HU198
• H75 and FO38
• DA34 and NI04
• Y159 and CY24
• HO01 and HON66
• B102 and GM39
• B106, B111, and GM37
• LXP90 and TOY48
• HY15
• KK10 and HY22

One key blank may be known by several numbers from different manufacturers. Review every listed cross-reference to confirm that the blade profile matches the intended lock.

Mechanical Test Keys

Mechanical test keys help locksmiths verify a decoded key or confirm whether a specific blade will operate a vehicle’s lock. They can be useful during lock servicing, impressioning, code work, and key-generation procedures.

Some products are specifically identified as test keys, while others can serve as test keys for compatible keyways. A test key generally does not include a transponder and should not be expected to start an immobilizer-equipped vehicle.

Plastic-Head Automotive Keys

Plastic-head mechanical keys combine a metal blade with a molded plastic head for comfortable handling and a finished appearance. These products may be used as non-transponder keys or for applications that do not require electronic immobilizer communication.

Confirm whether a chip is needed before cutting the key. A plastic head does not necessarily mean that a transponder is installed.

Transponder Key Shells With Chip Holders

This collection also includes key shells manufactured with an internal chip holder. These products provide the blade and shell needed to create a compatible transponder key when the correct chip is installed separately.

Available shell styles may support keyways such as:

• TOY43 and TR47
• H92 and H75
• HON66 and HO01
• B119 and HU100
• NI04 and DA34
• B111 and B106
• Y160 and Y159

A shell with a chip holder is not a complete transponder key unless the product listing specifically states that a chip is included. The correct transponder must be purchased, generated, installed, and programmed when required.

Individual Keys and Multipacks

Many mechanical keys are available in convenient multipacks for locksmith shops and mobile service vehicles. Pack quantities may vary by product and can include packs of five or ten keys.

Multipacks make it easier to maintain inventory of frequently used keyways while reducing the need to reorder individual blanks. Review the product title and description to confirm the quantity included.

JMA Automotive Keys

JMA manufactures automotive key blanks for many common vehicle applications. JMA keys may use proprietary reference numbers while also listing equivalent keyways from other manufacturers.

Use the cross-reference information shown in each listing to identify the correct JMA blank for the vehicle and cutting equipment.

ESP, Paladin, OEM, and Aftermarket Options

The collection also includes products from ESP, Paladin, OEM, and other aftermarket manufacturers. This variety gives automotive locksmiths several options based on keyway availability, pack quantity, application, and preferred brand.

Regardless of brand, inspect the blank and confirm its blade profile before beginning the cutting process.

Confirm the Blade and Keyway

Two mechanical keys may look similar while using different grooves, milling patterns, blade lengths, or shoulder positions. Attempting to insert or cut the wrong blank can damage the key, lock, or cutting equipment.

Before ordering, compare:

1. Vehicle year, make, and model
2. Keyway or blank number
3. Cross-reference numbers
4. Edge-cut or high-security blade design
5. Shoulder-stop or tip-stop configuration
6. Blade length and groove pattern
7. Plastic-head or metal-head construction
8. Individual or multipack quantity
9. Whether a chip holder is included
10. Whether a transponder chip is required

Key Cutting and Programming Requirements

Mechanical key blanks must be cut before use. Depending on the application, the key may be duplicated from an existing key or cut by code with compatible equipment.

Programming is not required for a true non-transponder mechanical key. However, if the vehicle uses an immobilizer, a compatible transponder chip must be installed and programmed before the completed key can start the engine.

A qualified automotive locksmith can verify the keyway, cut the blade accurately, identify the required chip, and complete programming when applicable.
