Toyota, Lexus & Scion Proximity Keys

Shop Toyota, Lexus, and Scion proximity keys for add-a-key, duplicate-key, and all-keys-lost services. Noble Key Supply carries an extensive selection of aftermarket, OEM, and refurbished smart keys for professional automotive locksmiths.

The collection includes proximity keys with different chips, frequencies, FCC IDs, board numbers, part numbers, emergency blades, and button configurations. Match every specification to the vehicle before ordering or programming a replacement.

Toyota Proximity Keys

Find Toyota smart keys for select cars, trucks, minivans, crossovers, and SUVs with passive-entry and push-button-start systems. Available products cover multiple Toyota key generations and include three-button, four-button, and six-button configurations.

Depending on the vehicle, remote functions may include:

• Lock
• Unlock
• Panic alarm
• Trunk release
• Rear-hatch release
• Power sliding-door operation
• Remote start

Toyota may use different proximity keys within the same vehicle line or model year. Production location, trim, installed options, and smart-entry configuration can all affect compatibility.

Lexus Proximity Keys

Shop Lexus smart keys for select sedans, coupes, crossovers, and SUVs. Available Lexus options include keys designed for different body styles, board generations, frequencies, and button arrangements.

Keys with the same FCC ID can contain different boards or support different vehicle applications. Compare the complete OEM part number and board information rather than selecting a key solely by housing appearance.

Scion Proximity Keys

Select Scion applications may share electronic platforms with Toyota vehicles. However, similar housings and FCC IDs do not guarantee that a Toyota smart key will work with a Scion.

Verify the vehicle’s year, model, original key, frequency, board number, chip technology, and programming requirements before selecting a replacement.

Toyota and Lexus Smart-Key Technology

A proximity key communicates wirelessly with the vehicle to support passive entry and push-button starting. When a programmed key is detected, the driver can unlock and start the vehicle without inserting a mechanical ignition key.

A complete smart key may include:

• Proximity and remote electronics
• An immobilizer transponder
• Remote-control buttons
• A replaceable battery
• An emergency insert blade
• A removable or integrated key housing

The key must be electronically registered with the vehicle before proximity and starting functions will operate.

8A Toyota Smart Keys

Many current Toyota proximity-key applications use 8A transponder technology. Available 8A keys include products with FCC IDs such as HYQ14FBA and related Toyota smart-key families.

An 8A chip alone does not determine compatibility. Technicians must also verify the frequency, board type, FCC ID, OEM part number, button layout, and vehicle production information.

Two keys may both contain 8A technology while supporting entirely different vehicles.

4D and DST80 Smart Keys

The collection also includes keys using 4D and DST80 transponder technology. These electronic systems appear across several Toyota and Lexus smart-key generations.

Examples include Lexus proximity keys that combine 4D and DST80 specifications. Programming equipment must support the exact immobilizer generation and vehicle platform.

Do not assume that every DST80 key can be substituted for another key with the same general chip description.

Smart-Key Frequencies

Toyota, Lexus, and Scion proximity keys may operate at different frequencies. Current collection options include:

• 312 MHz
• 314 MHz
• 315 MHz
• Dual 312/314 MHz configurations

Frequency must match the vehicle’s receiver and market specifications. A 315 MHz key cannot replace a 312/314 MHz version simply because the housing and buttons appear identical.

Common Toyota and Lexus FCC IDs

The collection includes smart keys associated with FCC IDs such as:

• HYQ14ACX
• HYQ14FBA
• HYQ14FBB
• HYQ14FBC
• HYQ14FLA
• HYQ14ADR
• HYQ14AAB
• MOZB31EG

The FCC ID is an important starting point, but it is not always sufficient by itself. Some FCC families are available with multiple board numbers, part numbers, button layouts, and vehicle applications.

Board Numbers and Smart-Key Compatibility

Toyota and Lexus smart keys may be identified by a board code or board number. Product listings may reference configurations such as GNE, G Board, E Board, or a numeric board designation.

Board information is especially important when two keys share the same FCC ID. Before purchasing, compare:

• FCC ID
• Board number or code
• OEM part number
• Transponder-chip technology
• Operating frequency
• Button layout
• Vehicle production location

Using all available identifiers reduces the likelihood of choosing an incompatible key.

Smart Entry vs. Non-Smart Entry

Some Toyota vehicles were available with different entry systems. A proximity key designed for a vehicle with smart entry may not be compatible with a vehicle using a different keyless-entry configuration.

Review the product description for smart-entry notes, especially when working with vehicles that offered several equipment packages. Confirm the installed system through the original key, vehicle data, or diagnostic equipment.

Toyota Highlander, RAV4, and Sienna Smart Keys

The collection includes smart keys for select Toyota Highlander, RAV4, and Sienna applications.

RAV4 keys may vary based on production location and board configuration. Sienna keys can have additional buttons for power sliding doors and the rear hatch. Highlander keys may use different FCC IDs or part numbers depending on model year and features.

Match the exact button icons and vehicle options before ordering.

Three-, Four-, and Six-Button Keys

Available proximity-key layouts include:

• Three-button keys: Commonly provide lock, unlock, and panic functions
• Four-button keys: May add trunk, hatch, or another vehicle-specific control
• Six-button keys: May support power sliding doors and rear-hatch functions on compatible minivans

A key with additional buttons is not automatically compatible. The transmitter, board, chip, and vehicle equipment must support those functions.

Aftermarket, OEM, and Refurbished Options

Noble Key Supply carries multiple proximity-key conditions:

• Aftermarket smart keys: Newly manufactured replacements for supported applications
• OEM proximity keys: Original manufacturer keys and electronics
• Refurbished OEM keys: Previously used original keys inspected and prepared for resale

A refurbished key may require unlocking, resetting, or reflashing before it can be programmed to another vehicle. Verify the product status and programmer capabilities before purchasing.

Emergency Insert Blades

Toyota, Lexus, and Scion proximity keys generally use an emergency blade for mechanical door access when the key or vehicle battery is discharged.

Confirm whether the blade is included and whether it matches the vehicle’s lock. The emergency blade may require separate cutting even after the electronic key has been programmed.

Programming Toyota and Lexus Proximity Keys

Smart-key programming requirements vary by vehicle, immobilizer generation, and job type. Adding a spare key can require a different procedure from an all-keys-lost situation.

Programming may require:

• Compatible automotive-key programming equipment
• Vehicle security or immobilizer data
• An existing registered smart key
• Online or security-code access
• Reset or reseed procedures
• Registration of every available key
• Stable vehicle battery voltage

Some later Toyota and Lexus systems may have additional security requirements. Confirm current tool coverage and the supported procedure before beginning.

Confirm Compatibility Before Ordering

Before purchasing a Toyota, Lexus, or Scion proximity key, verify:

• Vehicle year, make, model, and trim
• Vehicle production location
• Original FCC ID and IC number
• OEM and aftermarket part numbers
• Board number or board code
• 8A, 4D, or DST80 chip technology
• 312, 314, or 315 MHz frequency
• Button count and icons
• Smart-entry system configuration
• Emergency-blade requirements
• Aftermarket, OEM, or refurbished condition
• Programming-tool support

Checking several identifiers together helps prevent selecting a smart key that looks correct but cannot be programmed to the vehicle.
