Automotive Proximity Keys & Smart Keys

Shop automotive proximity keys for a wide range of vehicle makes, models, and years at Noble Key Supply. Our extensive smart-key collection supports professional locksmiths, automotive technicians, and key specialists completing add-a-key, replacement-key, and all-keys-lost services.

Browse new OEM, aftermarket, refurbished, recased, and locked proximity keys with different FCC IDs, frequencies, transponder chips, emergency blades, and button configurations. Review the complete product specifications to identify the correct key for the vehicle being serviced.

Smart Keys for Popular Vehicle Brands

Noble Key Supply carries automotive proximity keys for numerous domestic, Asian, and European manufacturers. Available vehicle categories include:

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

Inventory varies by vehicle application and product condition. Use the year, make, and model search when available, then compare the listing with the original key or trusted vehicle information.

OEM Proximity Keys

New OEM proximity keys use original-equipment components designed for their specified vehicle systems. They can be an appropriate choice when a customer or locksmith prefers a factory key.

Even when purchasing an OEM key, compatibility must be confirmed carefully. A manufacturer may use several part numbers, frequencies, circuit boards, or button arrangements for the same model year.

Aftermarket Smart Keys

Aftermarket proximity keys provide replacement options for supported vehicle applications. These keys can help locksmiths manage inventory costs while maintaining coverage for frequently serviced vehicles.

Available aftermarket brands and configurations vary by application. Check the FCC ID, part number, frequency, chip, blade, and programming requirements before ordering.

Refurbished and Recased Proximity Keys

Refurbished proximity keys use previously owned components that have been prepared for reuse. Available options may include Grade A and Grade B conditions, allowing locksmiths to select a key based on cosmetic expectations and budget.

Recased smart keys combine compatible electronics with a replacement exterior housing. Review each listing to determine the key’s condition and whether it includes a battery, emergency blade, logo, or other components.

Some refurbished or recased keys may require unlocking, resetting, or renewing before they can be programmed to another vehicle.

Locked Smart Keys

The collection also includes keys identified as locked. A locked smart key may still be paired with its previous vehicle or otherwise require specialized unlocking or renewal procedures before reuse.

Purchase a locked key only after confirming that you have compatible equipment, software, and technical support for the required process. A locked key generally cannot be programmed to another vehicle without completing the appropriate preparation procedure first.

Confirm Proximity-Key Compatibility

Smart keys that appear identical can contain completely different electronics. Before placing an order, verify:

  • Vehicle year, make, and model
  • OEM or replacement part number
  • FCC ID
  • IC number when applicable
  • Operating frequency
  • Transponder-chip type
  • Circuit-board information when provided
  • Button count and functions
  • Emergency-blade style
  • Product condition
  • Programming or unlocking requirements

Do not select a proximity key based only on its exterior appearance. A small difference in the frequency, chip, circuit board, or part number can make a key incompatible.

Proximity-Key Features

Depending on the vehicle, a proximity key may support functions such as:

  • Passive keyless entry
  • Push-button ignition
  • Lock and unlock
  • Trunk or liftgate release
  • Panic alarm
  • Remote start
  • Power sliding doors
  • Tailgate control
  • Vehicle-specific convenience features

The number and design of the buttons should match the vehicle’s installed equipment. Additional buttons do not automatically make a key compatible with a vehicle that does not support those functions.

Programming Automotive Smart Keys

A replacement proximity key must be programmed before it can operate the vehicle’s keyless-entry and push-to-start systems. Programming requirements vary considerably between manufacturers, models, years, and security platforms.

A job may require:

  • A compatible automotive key programmer
  • A security PIN or password
  • Dealer-level diagnostic software
  • Security-gateway access
  • An EEPROM or bench procedure
  • An adapter, cable, emulator, or specialized tool
  • Unlocking or renewing used electronics

Confirm that your programming equipment and software support the specific vehicle and key before beginning the job. Emergency blades may also need to be sourced or cut separately.

Proximity Keys for Professional Locksmiths

A well-planned smart-key inventory helps automotive locksmiths respond to more service calls without waiting to source every key individually. Stocking commonly requested applications can support faster duplicate-key appointments, lost-key replacements, and emergency mobile services.

Because modern smart-key systems change frequently, careful product identification remains essential. Verify all specifications before programming, cutting, or modifying a key.

Shop automotive proximity keys for a wide range of vehicle makes, models, and years at Noble Key Supply. Our extensive smart-key collection supports professional locksmiths, automotive technicians, and key specialists completing add-a-key, replacement-key, and all-keys-lost services.

Browse new OEM, aftermarket, refurbished, recased, and locked proximity keys with different FCC IDs, frequencies, transponder chips, emergency blades, and button configurations. Review the complete product specifications to identify the correct key for the vehicle being serviced.

Smart Keys for Popular Vehicle Brands

Noble Key Supply carries automotive proximity keys for numerous domestic, Asian, and European manufacturers. Available vehicle categories include:

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

Inventory varies by vehicle application and product condition. Use the year, make, and model search when available, then compare the listing with the original key or trusted vehicle information.

OEM Proximity Keys

New OEM proximity keys use original-equipment components designed for their specified vehicle systems. They can be an appropriate choice when a customer or locksmith prefers a factory key.

Even when purchasing an OEM key, compatibility must be confirmed carefully. A manufacturer may use several part numbers, frequencies, circuit boards, or button arrangements for the same model year.

Aftermarket Smart Keys

Aftermarket proximity keys provide replacement options for supported vehicle applications. These keys can help locksmiths manage inventory costs while maintaining coverage for frequently serviced vehicles.

Available aftermarket brands and configurations vary by application. Check the FCC ID, part number, frequency, chip, blade, and programming requirements before ordering.

Refurbished and Recased Proximity Keys

Refurbished proximity keys use previously owned components that have been prepared for reuse. Available options may include Grade A and Grade B conditions, allowing locksmiths to select a key based on cosmetic expectations and budget.

Recased smart keys combine compatible electronics with a replacement exterior housing. Review each listing to determine the key’s condition and whether it includes a battery, emergency blade, logo, or other components.

Some refurbished or recased keys may require unlocking, resetting, or renewing before they can be programmed to another vehicle.

Locked Smart Keys

The collection also includes keys identified as locked. A locked smart key may still be paired with its previous vehicle or otherwise require specialized unlocking or renewal procedures before reuse.

Purchase a locked key only after confirming that you have compatible equipment, software, and technical support for the required process. A locked key generally cannot be programmed to another vehicle without completing the appropriate preparation procedure first.

Confirm Proximity-Key Compatibility

Smart keys that appear identical can contain completely different electronics. Before placing an order, verify:

  • Vehicle year, make, and model
  • OEM or replacement part number
  • FCC ID
  • IC number when applicable
  • Operating frequency
  • Transponder-chip type
  • Circuit-board information when provided
  • Button count and functions
  • Emergency-blade style
  • Product condition
  • Programming or unlocking requirements

Do not select a proximity key based only on its exterior appearance. A small difference in the frequency, chip, circuit board, or part number can make a key incompatible.

Proximity-Key Features

Depending on the vehicle, a proximity key may support functions such as:

  • Passive keyless entry
  • Push-button ignition
  • Lock and unlock
  • Trunk or liftgate release
  • Panic alarm
  • Remote start
  • Power sliding doors
  • Tailgate control
  • Vehicle-specific convenience features

The number and design of the buttons should match the vehicle’s installed equipment. Additional buttons do not automatically make a key compatible with a vehicle that does not support those functions.

Programming Automotive Smart Keys

A replacement proximity key must be programmed before it can operate the vehicle’s keyless-entry and push-to-start systems. Programming requirements vary considerably between manufacturers, models, years, and security platforms.

A job may require:

  • A compatible automotive key programmer
  • A security PIN or password
  • Dealer-level diagnostic software
  • Security-gateway access
  • An EEPROM or bench procedure
  • An adapter, cable, emulator, or specialized tool
  • Unlocking or renewing used electronics

Confirm that your programming equipment and software support the specific vehicle and key before beginning the job. Emergency blades may also need to be sourced or cut separately.

Proximity Keys for Professional Locksmiths

A well-planned smart-key inventory helps automotive locksmiths respond to more service calls without waiting to source every key individually. Stocking commonly requested applications can support faster duplicate-key appointments, lost-key replacements, and emergency mobile services.

Because modern smart-key systems change frequently, careful product identification remains essential. Verify all specifications before programming, cutting, or modifying a key.
