EoneBoss TLK3: Next-Gen Smart Key Solution for Toyota, Lexus & Subaru

EoneBoss has introduced the TLK3, a new smart key solution designed for Toyota, Lexus, and Subaru vehicles. Compared with previous TLK series devices, TLK3 expands support for more key chip types and introduces one-click unlocking, making the key preparation process more convenient for supported vehicles.

EoneBoss TLK3 Features

Smart Key Unlocking

The TLK3 supports unlocking for the following smart key chips:

4D

8A

4A

Auto Identification & ET Generation

TLK3 can automatically identify:

Key type

Frequency

Dual-frequency sequence

After identification, it can directly generate the corresponding ET series key.

Note: ET generation is not a direct key clone. Vehicle programming is still required after generating the key.

AKL (All Keys Lost) Generation

For all key-lost situations, TLK3 can capture the vehicle ignition signal and automatically identify the required key information for key generation.

Multi-Frequency Detection

TLK3 supports frequency detection for multiple ranges, including:

300–316 MHz

430–436 MHz

868 MHz

902 MHz

EoneBoss TLK Series Comparison

The TLK series currently includes TLK1, TLK2, and TLK3.

Note: TLK1, TLK2, and TLK3 devices are not compatible with each other.

Summary

The EoneBoss TLK3 expands the capabilities of the TLK series by supporting 4D, 8A, and 4A smart key unlocking, automatic key identification and ET generation, AKL key generation, and multi-frequency detection.

Compared with TLK1 and TLK2, TLK3 is designed for aftermarket and dealership keys, offers one-click unlocking, and supports a wider range of key chips through its app-based operation, making it a practical addition for professionals working with Toyota, Lexus, and Subaru smart keys.
