EONEBOSS TLK1 Toyota & Lexus Smart Key Reuse Device (8A / AA / BA / B9 / B8)

The EONEBOSS TLK1 is a professional key reuse and matching device developed specifically for Toyota and Lexus smart keys using 8A, AA, BA, B9, and B8 systems. It is designed to solve one of the most common challenges faced by automotive locksmiths: reusing locked OEM keys that cannot be refreshed due to encryption limitations.

Unlike traditional methods that require unlocking, reflashing, soldering, or key disassembly, the TLK1 introduces an innovative non-destructive matching process. It allows used and locked keys to be matched directly to vehicles without unlocking, significantly reducing operating costs and eliminating the need to discard expensive original keys.

This solution is ideal for professionals working with Toyota/Lexus proximity systems from 2010 to 2022+, offering a safer, faster, and more economical alternative to conventional key reuse workflows.
