Toyota, Lexus & Scion Transponder Keys

Shop Toyota, Lexus, and Scion transponder keys for a variety of vehicle years and immobilizer systems at Noble Key Supply. This collection includes aftermarket chip keys for professional locksmiths and automotive key specialists completing duplicate-key and all-keys-lost services.

Browse transponder keys with 4C, 4D, G, H, 67, 68, 72, and other chip technologies. Available keyways include TOY40, TOY43, TOY48, and related Toyota and Lexus applications.

Toyota Transponder Keys

Toyota has used several transponder-chip systems and blade profiles across its vehicle lineup. Available applications may cover select models such as the Camry, Corolla, Avalon, Prius, RAV4, Highlander, Tacoma, Tundra, Sienna, 4Runner, and other vehicles.

Two Toyota keys can use the same mechanical blade while requiring different transponder chips. Confirm both the keyway and chip type before cutting or programming a replacement.

Lexus Transponder Keys

Find Lexus transponder keys for compatible vehicles using traditional keyed-ignition systems. Lexus applications may use TOY40, TOY48, LXP90, or related blade profiles depending on the model and year.

Some keys use standard 4C or 4D technology, while others require a G-Chip or H-Chip application. The transponder and blade must both match the vehicle’s immobilizer system.

Scion Chip Keys

Shop transponder keys for select Scion vehicles equipped with immobilizer systems. Scion shares many key and security technologies with Toyota, but compatibility should still be verified by exact year, model, chip, and keyway.

Use the product listing and reliable vehicle data to determine whether the application requires a 4C, 4D, G, H, or other supported transponder.

Toyota G-Chip Keys

Toyota G-Chip keys use a specific transponder system identified by a “G” marking on many original keys. The collection includes select TOY44G, TOY48G, TOY49G, and related applications.

Not all G-Chips are interchangeable. Certain applications may require a special G-Chip configuration or a specific page value. Confirm the precise chip specification before ordering or programming the key.

Toyota H-Chip Keys

Toyota H-Chip systems are used in numerous later keyed-ignition vehicles. Available products include select TOY44H and TOY48H transponder-key applications.

An H-Chip key cannot be selected by blade profile alone. Verify that the vehicle requires an H transponder and that your programming equipment supports the application.

4C and 4D Transponder Keys

This collection also includes Toyota, Lexus, and Scion keys using common 4C and 4D chip families, including select:

• ID4C transponder keys
• 4D67 applications
• 4D68 applications
• 4D72 G-Chip applications
• 4C keys with TOY40, TOY43, and TOY48 blade styles

Although chip-family names may be similar, the exact immobilizer system must be identified before programming.

Common Toyota and Lexus Keyways

Available keys cover several mechanical blade profiles, including:

• TOY40
• TOY43
• TOY48
• TR40
• TR47
• LXP90
• Reverse and specialty Toyota keyways

The test-key or Lishi reference shown in a listing can help identify the mechanical profile. Compare the original key and vehicle data before cutting the replacement.

Confirm Transponder-Key Compatibility

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

• Vehicle year, make, and model
• Transponder-chip type
• Keyway and blade profile
• Original or replacement part number
• Test-key reference
• Lishi reference when applicable
• Standard or reverse blade orientation
• Required programming procedure
• Programmer and software compatibility

A correctly cut blade with the wrong chip may operate the ignition cylinder but will not start the vehicle. Likewise, a compatible chip installed in the wrong blade cannot operate the mechanical locks.

Cutting Toyota, Lexus, and Scion Keys

The blade must be cut to the vehicle’s mechanical key code or decoded from an existing working key. Use the correct machine jaw, cutting card, cutter, and key profile for the application.

Test the cut blade mechanically before programming. It should enter and operate the ignition and applicable door locks smoothly without excessive force.

Programming Toyota Transponder Keys

Programming requirements vary by vehicle, immobilizer generation, and number of working keys available. Depending on the application, the job may involve:

• An onboard add-a-key procedure
• Diagnostic programming
• A security reset or waiting period
• Seed-code or PIN-related access
• EEPROM or immobilizer-data work
• Transponder cloning

An all-keys-lost job can require a different process than adding a key when a programmed master key is available. Confirm the appropriate procedure before beginning.
