Lonsdor Super ADP 8A/4A Adapter for Toyota Lexus Proximity Key Programming

This is a key programming adapter designed to work with Lonsdor K518 series programmers (e.g., K518ISE, K518S). It enables key programming tasks on many Toyota and Lexus vehicles equipped with proximity smart keys, specifically 8A and 4A smart key systems, without requiring dealer PIN codes or an AKL (All Keys Lost) subscription/license.

Key Capabilities

• Supports 90%+ Toyota and Lexus vehicles (typically models up to around 2021) with 8A (DST‑AES 88 A8 A9 AA) and 4A (HITAG‑AES) smart key systems.

• No PIN or AKL license needed for most programming via OBD (On‑Board Diagnostics).

• Works with Lonsdor K518 series only — must be connected through the K518 tool.

•  Can program new proximity keys, backup immobilizer data, add keys, delete keys, and perform All Keys Lost operations (with an additional LKE smart key emulator for AKL).

• Reuses immobilizer data read from the smart box for programming.
