Vehicle Compatibility

Toyota

• 4Runner: 2010–2019
• Prius: 2010–2012
• Prius C: 2012–2014
• Prius V: 2012–2016
• Venza: 2009–2016

Scion

• tC: 2011–2016

For Toyota Venza, specify:

3-button configuration / vehicles without Power Back Door

The 89904-47230 / HYQ14ACX / 5290 three-button family is documented for 4Runner, Venza, Prius-family applications and Scion tC. For Venza 2009–2016 the correct application is without power back door, an important distinction because power-back-door configurations require an additional button.

The 89904-47230 part number is also associated with Prius 2010–2012 and Prius V applications.

Important Compatibility Note

HYQ14ACX / 5290 exists in multiple Toyota and Lexus button configurations.

Do not determine compatibility from FCC ID or board number alone.

This Palmetto product is the 3-button Lock / Unlock / Panic configuration. The original remote should match:

• FCC ID HYQ14ACX
• 5290 board family
• 3-button layout
• compatible 3-button OEM P/N family
• appropriate vehicle application

This is particularly important because Lexus remotes using the same FCC ID and 5290 electronics can have Trunk, Hatch, or Glass/Hatch buttons and are not direct physical replacements for this SKU.

Programming & Compatibility

This smart key requires professional programming to the vehicle's immobilizer and proximity system before use.

The smart-key credential and remote functions must be registered using compatible Toyota / Scion locksmith or dealer programming equipment.

Do not expect a standard customer onboard programming procedure for this application. The emergency insert key must also be cut to match the vehicle before mechanical use. Professional programming is specified for the 89904-47230 family.

Because the HYQ14ACX family includes several button and vehicle configurations, FCC ID alone should never be used to determine compatibility.
