Important Compatibility Note
HYQ14ACX / 5290 is used across 2-button, 3-button, and multiple 4-button Toyota/Lexus configurations.
This Palmetto product is specifically the 3+1 / 4-button version.
The rear-access button may perform a different function depending on the vehicle:
- Trunk
- Rear Hatch
- Glass Hatch
The original FCC ID, board, frequency, button count, OEM P/N and vehicle application should all be verified before ordering or programming.
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 / Lexus locksmith or dealer programming equipment.
Do not expect a standard customer onboard programming procedure for this application.
Because multiple HYQ14ACX remotes share the same 5290 board family while using different button configurations, compatibility should not be determined from FCC ID or board number alone.
