Ford remote start won’t work when cold

Thread starter #1
2015 f250 6.7 power stroke won’t remote start when cold over the last few days. Attempts to start for about 1-2 seconds then has a about a 5 second pause then the horn beeps once. It starts fine with the key. After the initial start of the day it will remote start without problem. Dealer said it has to malfunction for them but when I have to drive 30 miles to them it obviously won’t malfunction at that point as it’s warm.

Mine has done that once, but it was a random occurrence. Being temp. related, the battery would be the first thing to check. My understanding is It will do that any time there is a fault - low voltage, door open, alarm triggered, check engine light one, etc. I'm sure the remote start is more sensitive to voltage than you turning the key.
