2014 IS250/IS350 which guide to use?

Question

Under Evo-all guides as a stand-alone.

It shows 2 different guides.

1 does not have guide number but revision date 20140409 which I need to sacrifice 1 keyfob.

Another on has guide number 23541 without sacrificing 1 keyfob.

 

Which one do I follow?

Answer 1

I would personally use the one without losing a key.

The reason for having two guides is in the Compatibility Notes section, here is what it says :

Two different types of installation. With and without key take-over. No key required on the no-key-take-over installation and the OEM remote stays functional when the vehicle is remote started. The key-take-over plan requires a key for the installation and the OEM remotes do not work when the vehicle is remote started.
