One customer wanted to bind Lonsdor Super ADP 8A/4A Adapter to K518 Pro to do smart key programming for TOYOTA/Lexus (2017-2021) without PIN & TOYOTA AKL license. He entered the Bind adapter option, but got the “Communication failure” error.

For this problem, eobdtool.co.uk engineer offered the solution below.

Lonsdor K518 Pro and Super AD bind guide is the same as Lonsdor K518ISE.

Plug Lonsdor Super ADP Adapter into the K518 device

Plug the 12V power supply to K518 key programmer as well

Then enter the menu path:

Immo & Remote>> TOYOTA>> Select from type>> All smart key lost>> Type 2 (2016-)>> 8A>> Backup immo data>> Backup immo data via ADP

Kindly notice:

During the use of ADP, do not operate abnormally, or maliciously steal relevant data, otherwise the K518 and ADP will be locked and cannot be unlocked.

The program will prompt you to bind Toyota adapter and K518Pro. Follow it to bind and wait for the process to be completed.
