Here's a quick breakdown of all three EoneBoss tools to help clarify:
🔹 TLK1 – For Toyota/Lexus OEM locked keys with 8A-AA, BA, B9, and B8 chips. It reuses locked original keys non-destructively without soldering or opening the key shell.
🔹 TLK2 – For Toyota/Lexus OEM locked keys with 4A-AA and BA chips. Same non-destructive 3-step process as the TLK1, but designed specifically for the 4A chip family.
🔹 TLK3 – For EoneBoss (not OEM) Toyota, Lexus, and Subaru smart keys. It supports All Keys Lost (AKL) scenarios and automatically detects chip type, vehicle brand, and frequency sequence. Includes support for data reading and chip identification.
⚠️ Important: TLK1, TLK2, and TLK3 are NOT compatible with each other — each one is a separate tool for a different key type. They works as a standalone tool — it does not require a specific programmer to unlock the key. Once the key is unlocked you can then use a key programmer.
