Will Lonsdor K518 Pro Add Toyota 8A B9 Smart Key?

Problem:

Tried to add a smart key for Toyota Landcruiser year 2025 8A Page4 B9 433Mhz. Xhorse XM smart key won’t work. What device to add a smart key on this 8A B9 model?

Here is the clue.

Toyota 8A-B9 smart key is primarily used in newer models equipped with the 30-pin smart key box (TMLF19D).

Xhorse does not add key 8A B9 system, only 8A BA.

Lonsdor K518 Pro will add key for Toyota Lexus 2024+ 8A P4 B9 models. You will need FP30 30 pin cable to back up immo data. But the programmed Lonsdor key (LT32) does not have keyless function.

After market key only has remote and emergency functions.

8A B9 is UWB key. None of aftermarket keys will work on that car (will only work remote and emergency start). If you want a fully working key you will need the original.

Xhorse, Autel, Keydiy keys are not working.

Original key will be $550 with blade.
