Try turning off the security feature.Is there a way (Forscan) to disable that silly motion sensor for good...
Not sure why there would even be an alarm if it's running. Turn off power down timer (or disable permanently with forscan), leave truck on and go about your business. No need to leave the key or phone in the truck. Not sure how the alarm works if you lock it and leave it with it running though but haven't had a busy dog set it off.I think the OP's point is yes the truck stays running when you leave with the keys (or phone) but if the passengers shift around to much the car alarm goes off.
Yeah my 2023 doesn’t have the interior motion sensor either. There’s this whole thread about how to add it back. https://www.f150lightningforum.com/forum/threads/ford-perimeter-plus-security-system.15665/Thinking about it, mine may not even have it. Don't recall any settings and it's a 23 where they were leaving stuff out.
