Honda & Acura Proximity Keys

Shop Honda and Acura proximity keys for professional automotive locksmith services, replacement-key jobs, and inventory restocking. Noble Key Supply carries a large selection of smart keys for compatible Honda and Acura vehicles, including new OEM, refurbished OEM, and aftermarket options.

Available keys feature multiple button layouts, transponder chips, operating frequencies, FCC IDs, and manufacturer part numbers. Review all listed specifications and compare them with the original key before ordering.

Honda and Acura Smart Key Replacement Options

Honda and Acura proximity keys provide keyless-entry and push-to-start functionality for compatible vehicles. Depending on the application, a smart key may also control remote start, trunk release, rear-hatch access, power sliding doors, and memory-seat functions.

Available options may include:

• Four-, five-, six-, and seven-button configurations
• Keys with or without driver-memory functions
• Sedan, SUV, truck, and minivan layouts
• 47 and 4A transponder-chip technologies
• 313 MHz, 313.8 MHz, 314 MHz, 433 MHz, and 434 MHz frequencies
• New OEM, refurbished OEM, and aftermarket keys
• Compatible emergency insert blades

Similar-looking keys are not necessarily interchangeable. Always verify the complete specifications for the vehicle being serviced.

Honda Proximity Keys

The collection includes Honda smart keys for a broad range of compatible cars, SUVs, trucks, and minivans. Button functions may include lock, unlock, panic, trunk, rear hatch, remote start, and power sliding-door controls.

Because Honda uses multiple electronic configurations, matching the key’s FCC ID, frequency, part number, buttons, and memory designation is essential.

Acura Proximity Keys

Acura proximity keys are available for compatible luxury cars and SUVs equipped with keyless-access and push-button-start systems. Some Acura keys share a similar shape with Honda keys but use different electronics or button functions.

Confirm the vehicle year, model, trim, FCC ID, manufacturer part number, frequency, and driver-memory configuration before choosing an Acura replacement key.

Proximity Keys With and Without Driver Memory

Certain Honda and Acura vehicles use separate smart keys for Driver 1 and Driver 2 memory settings. Other applications use keys without a memory designation.

When applicable, determine whether the vehicle needs a Driver 1, Driver 2, or no-memory key. The exterior appearance may be similar even when the internal configuration or identification markings differ.

Honda and Acura Smart-Key Frequencies

Honda and Acura proximity keys are available with several operating frequencies, including:

• 313 MHz
• 313.8 MHz
• 314 MHz
• 433 MHz
• 434 MHz

The frequency must match the vehicle’s system. An incorrect-frequency key may not operate the remote functions or communicate correctly during programming.

Match the FCC ID

The FCC ID is one of the most valuable identifiers for selecting a compatible Honda or Acura proximity key. FCC IDs represented within the collection include:

• KR5V1X
• KR5V2X
• KR5T4X
• KR5V44
• KR5T44
• KR5TP-4
• CWTWB1G0090
• ACJ932HK1210A
• ACJ932HK1310A

Compare the entire FCC ID from the original key with the replacement listing. Small differences can indicate another frequency, circuit board, button configuration, or vehicle application.

Verify the Manufacturer Part Number

Honda and Acura smart keys can also be identified by the manufacturer part number. Examples found throughout the collection include:

• 72147-TG7-A11
• 72147-TVA-A01
• 72147-TBA-A11
• 72147-T43-A11
• 72147-T2A-A01
• 72147-TZ5-A01
• 72147-TVA-A11
• 72147-T20-A11
• 72147-TK8-A51
• 72147-THR-A11
• 72147-THR-A51
• 72147-TG7-A81
• 72147-T6Z-A11
• 72147-TZ3-A21
• 72147-T7S-A01

Use the part number together with the FCC ID, frequency, buttons, and memory designation to identify the correct key.

Four- and Five-Button Smart Keys

Four- and five-button keys are common across many Honda and Acura applications. Depending on the vehicle, buttons may control lock, unlock, panic, trunk release, rear-hatch access, or remote start.

Match the number, position, and symbols of the buttons to the original key. A similar shell does not guarantee that every remote function will operate.

Six- and Seven-Button Honda Minivan Keys

Compatible Honda minivans may use six- or seven-button proximity keys with left and right power sliding-door controls. Some layouts also include remote start or a power rear-hatch button.

These keys require careful identification because several versions can look nearly identical. Verify the FCC ID, frequency, part number, memory designation, and complete button layout.

New OEM Honda and Acura Keys

New OEM proximity keys use original-equipment components and are intended for their specified Honda or Acura applications. They are a strong choice when a new factory smart key is preferred.

An OEM designation does not eliminate the need for compatibility checks. Confirm every available identifier before ordering.

Refurbished OEM Smart Keys

Refurbished Honda and Acura keys reuse genuine OEM electronics and are often offered in Grade A or Grade B cosmetic condition. They provide an alternative to purchasing a new OEM key while retaining original-equipment circuitry.

A refurbished key may require unlocking, resetting, or preparation before it can be programmed to another vehicle. Verify its status and programming requirements before beginning the job.

Paladin and Other Aftermarket Proximity Keys

Aftermarket keys provide a cost-effective option for supported Honda and Acura applications. The collection includes Paladin premium aftermarket keys and other replacement-key choices.

Paladin keys are designed as reliable, quality-tested alternatives for professional automotive key services. Compatibility should still be confirmed using the vehicle information and all available key specifications.

Emergency Insert-Key Blades

Many Honda and Acura smart keys use a removable emergency blade for manually unlocking the vehicle. Compatible insert blades may also be available within the collection.

Blade style and keyway can vary. Verify compatibility before cutting, and do not assume that every proximity key includes an emergency blade unless the individual product listing states that it does.

Professional Programming Is Required

Honda and Acura proximity keys generally require professional programming before they can start the vehicle and operate remote functions. Procedures vary by vehicle, model year, key type, transponder, and security system.

A qualified automotive locksmith or key technician can confirm programming-tool coverage, prepare the key when necessary, cut the emergency blade, and complete the required programming procedure.

How to Choose the Correct Honda or Acura Proximity Key

Verify the following information before ordering:

1. Vehicle year, make, model, and trim
2. FCC ID
3. Manufacturer part number
4. IC or circuit-board identifier
5. Transponder-chip type
6. Operating frequency
7. Number of buttons
8. Button symbols and remote functions
9. Driver-memory designation
10. Emergency-blade style
11. OEM, refurbished, or aftermarket condition
12. Programming-tool compatibility

Checking these details helps reduce incorrect orders, programming failures, and service delays.
