I know there are a few threads on remote start and I have read most of them but my question is a bit different. So I had a small trailer hooked up to take my lawnmower to my in-laws house. I was by myself and wanted to make sure the trailer lights were working. so I hit the lock button knowing it would make the lights flash. the trailer lights didn't flash so I hit lock again. Sill nothing so I hit unlock a couple of times. to my surprise the expedition started. I do not have a remote start Fob. it is the normal fob integrated with the key. just lock, unlock, lift gate, and alarm buttons. I also don't see anything in the manual about remote start other than it saying there was a dealer installed option. I thought the dealer option came with new fobs. I have tried this a few times to make sure I was not hallucinating and i even managed to turn it off remotely. is this normal? seems too easy. we bought this last July and it has about 65k miles on it.
