The top advantage of the Lonsdor ADP adapter is that you can bypass the seed code (LSID) without Techstream subscription with NASTF. Data read by ADP adapter can be reused for programming. The rolling code from dealer changes each time. Repeated query when programming failed. What’s more, ADP adapter works without Toyota AKL license. You can still use the ADP adapter even if your Lonsdor K518ISE software has expired.
