EoneBoss ET-02 Toyota/Lexus Universal Smart Remote Key PCB – 4-Button, 4D & 8A Transponder (Bluetooth App-Programmable)

The EoneBoss ET-02 Universal Smart Remote Key PCB is a Bluetooth app-programmable replacement PCB built for Toyota and Lexus smart key applications. Sharing the same core platform as the ET-01, the ET-02 is distinguished by its ASK modulation and a default frequency of 314.35MHz, making it suited to a different range of Toyota board numbers including 3370, 0140, A433/F433, 5290, and S5290.

With a 4-button layout covering lock, unlock, trunk, and panic functions, the ET-02 delivers OEM-level performance at an aftermarket price point. 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 across a wide range of Toyota models from 2012 onward.

Sold as a PCB only. Shell and CR2032 battery must be purchased separately.

Compatible Board Numbers: 3370, 0140, A433/F433, 5290, S5290

A standout feature of the ET-02 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

2. Customizable Button Functions (via Phone App)

The ET-02's 4 buttons can be individually programmed for core functions including door lock/unlock, trunk release, and panic alarm activation. This gives technicians the flexibility to configure the remote to fit specific use cases, including emergency scenarios.

3. Compatible with Mobile App Programming — No Dedicated Device Required

Programming the ET-02 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.

Advantages of Choosing EoneBoss ET-02

The ET-02 offers a cost-effective alternative to OEM remote controls, delivering comparable reliability at a fraction of the price. Its adjustable frequency and customizable buttons make it highly versatile and easy to set up via the EoneBoss app, while broad compatibility across Toyota sedans, SUVs, and trucks ensures it fits a wide range of replacement and add-key scenarios.
