I will check that, thank you. As an update, I was able to program two new Ford factory fobs using the instructions in the owner's manual so it appears that the factory remote keyless entry system is working. I just disarmed the after market alarm system with its fob and began using the factory fobs. They are much more responsive than the alarm system fobs. With the alarm system fob, I have to hold the trunk button for 4 seconds before the trunk will open and it doesn't work every time. The unlock button doesn't unlock the doors everytime, sometimes I have to press lock and unlock again to get the doors to unlock. With the factory fobs using the remote keyless entry, door locking/unlocking and the trunk button respond immediately every time. I found a Ford factory alarm system on EBay that is desgined to be added to the factory remote keyless entry so I am going to have my dealer remove the after market alarm system and install the factory on in its place.
