Lonsdor LT20-10 Toyota / Lexus Universal Smart Remote Key PCB 5 buttons

Universal Smart Key PCB – These boards are replacement internal circuit boards (PCB) used inside the smart key fob shell for Toyota and Lexus vehicles. They don’t include the shell case or key blade by default; those are often sold separately.

Adjustable frequency & transponder – LT20‑10 boards support multiple radio frequencies (e.g., ~312/314/433 MHz bands) and use 8A‑BA transponder IDs, so they can be programmed to many newer Toyota/Lexus smart key systems.

Programming – These PCBs typically require a key programmer (e.g., Lonsdor tools such as K518/KH100+) to read, program transponder information, and set remote functions correctly.
