Hey all. Back in 2015 I installed my uncles remote start with your help. A few months ago it just stopped working. I couldn't work on it as I'd been quite ill with Lyme Disease. Finally feeling better now and fixed my own issue recently and figured it was time to get my uncles car sorted.
It's a push to start 2015 rogue (not sport). Viper 5706v/iDatalink ALCA module for the doors/transponder bypass.
What happens is that when a complete key fob is near the car, it remote starts right up. When there is no keyfob near the car, it goes to start but does nothing. I figured it was something with the immobilizer setup. We had to use a 2nd key and pulled the valet key, battery, and half the fob off. A coiled wire is placed over the coil on the rest of it. I'm sure you experienced guys know what I'm talking about. Any way, I untaped it and everything looked fine. I'm temped to try the other fob.
Any idea what could go wrong after years of working with what I'm guessing is the immobilizer?
Attaching the documentation I used below.
Hopefully there are some known scenarios/resolutions you guys can share with me.
Thanks all.

Quick update. Tried a different key fob for the key wrap and it has the same exact issue. Not sure what to try next. If a key is in the cabin it remote starts without issue.
so you said, if you leave a key inside it will remote start fine? did your uncle lose any of the keys? was there any IMMO reprograming done? if you take apart the keys, *(take the battery out)* and place the back up immmo on the pts button, will it start?
My guess is immo was reprogramed and the locksmith / dealer didn't reprogram the backup IMMO, and only did the smart key
