This video will give you a step by step walkthrough for installing proximity entry on a 2018+ JL or JT using the parts found at https://www.jlwranglerforums.com/foru...

Tools needed include:
T20 Torx
T25 Torx (Long)
T30 Torx
10mm deepwell socket
Masking tape
Interior panel tool

Please note that I already had the option code added on my Gladiator, and that is why it worked immediately. This is a very important step that can be read about at the above link.

Hope this helps!
