Update: I see now this has already been discussed. Sorry for the repeat.

Member sstevetx mentioned this in a post about programming a key. I tried it and it works. It’s a cool capability so I’m pointing it out for everybody that’s interested.

If you program a key fob to your truck that has traditional remote start instead of the frunk button, you can remote start the truck just like an ICE F150. So, if you can’t start the cabin warmup with the app, you can start it from the key fob. It functions just as if you had started it from the app.

With the cold weather we’ve been having I’ve found that at very cold temps the BMS will shutdown several features to preserve the 12v SOC. This happens even when the 12v is at a high SOC - happened to my truck after 9 hours at work with the 12v at over 90% charge with outdoor air temps below -5F. One of the features that gets shutdown is the connected features modem. So, when I most wanted to preheat the cabin my app couldn’t connect.

If you decide to try it, make sure to pick a fob with the right frequency. My 24 Flash key fob is 433 MHz. Earlier trucks were 315 MHz. Best approach is to check your Fob FCC ID to confirm your frequency.

I've had it happen multiple times this winter at work after only 5 or 6 hours between 30-40 degrees F. The saver is very conservative and really seems like an oversight as to have at least given us the possibility of starting using the default key fob from the factory.

I assumed there was no remote start on key fob due to something within the EV platform but it irritates me more that it's actually built in and they just didn't provide it :cwl:

So this wouldn’t work with the 315mhz fob?
I believe you just need to use a key fob with a frequency that matches your original key fob frequency. I think it’s 315 MHz for the 22 and 23, and 433 MHZ for the 24 - but you should verify before buying a new fob. My experience is only with my 24 Flash.
