The EoneBoss ET-08 Universal Smart Remote Key PCB is a Bluetooth app-programmable replacement PCB built for Toyota and Lexus smart key applications requiring flexible button configuration. Unique within the EoneBoss ET series, the ET-08 supports 4, 5, or 6-button layouts on a single board — all configurable via the EoneBoss app — making it one of the most adaptable PCBs in the lineup.
In its 4-button configuration, the ET-08 covers lock, unlock, liftgate, and panic functions, and is compatible with board number 3041 using FSK modulation at a default dual frequency of 312.09/314.35MHz. It covers a wide range of late-model Toyota and Lexus vehicles from 2016 through 2024, including the Tundra, Sienna, Land Cruiser, Alphard, Vellfire, Crown, and Lexus LX6.
Frequency and button configurations are fully adjustable through the EoneBoss Bluetooth app — no dedicated key programmer required — and the board supports both Add Key and All Keys Lost (AKL) scenarios.
Sold as a PCB only. Shell and CR2032 battery must be purchased separately.
Compatible Board Numbers: 3041

1. Adjustable Frequency (via Phone App)
A standout feature of the ET-08 is its adjustable frequency capability. Using the EoneBoss mobile app, the remote can be programmed to generate multiple frequencies, giving it broad compatibility across older and newer Toyota models alike. This allows technicians to fine-tune the remote to match the exact vehicle requirement, improving both usability and reliability in the field. Supported frequencies include:
Dual Frequency (MHz): 312.09/314.35, 312.50/313.09, 312.09/314.00, 313.09/312.09, 314.00/312.50, 314.00/315.10, 314.35/312.09, 314.35/315.10, 314.10/314.00, 315.10/314.35, 315.10/314.00, 433.58/434.30, 433.58/434.42, 434.30/433.58, 434.42/433.58
Single Frequency (MHz): 312.15, 314.01, 314.35, 314.358, 315.12, 315.128, 315.15, 433.92, 433.93
2. Customizable Button Functions (via Phone App)
The ET-08 supports 4, 5, or 6-button configurations, each programmable for specific functions via the EoneBoss app. The 4-button layout covers lock, unlock, liftgate, and panic; the 5-button layout adds A/C control; and the 6-button layout further extends to left and right sliding door operation. This flexibility makes the ET-08 suitable for a wide range of Toyota vehicle types and use cases.
3. Compatible with Mobile App Programming — No Dedicated Device Required
Programming the ET-08 only requires downloading the EoneBoss app, available on both the Android Play Store and the iPhone App Store, then connecting via Bluetooth. There's no need to invest in a separate dedicated programming device, simplifying the workflow significantly. Once programmed, the key can be matched to the vehicle using any compatible third-party programming device.
The ET-08 offers a cost-effective alternative to OEM remote controls, delivering comparable reliability at a fraction of the price. Its adjustable frequency, configurable button count (4, 5, or 6 buttons), and app-based programming make it one of the most versatile options in the EoneBoss ET series, covering a broad range of Toyota and Lexus replacement and add-key scenarios.
