I was wondering if anybody could help me. I have a 2005 F150 SuperCrew Cab/ Lariat and I am having problems with my keyless entry not operating correctly when I press any button on the key-chain remotes unless I'm within 5 to 15 feet of the vehicle.

It started a couple of months ago out of the blue. I first tried changing the battery in my primary key-chain remote but that had no effect. Then I went to my secondary key-chain remote and put a new battery in it and it still didn't work properly. So I tried the internet to see if anybody else has had this problem but I can't seem to find anybody. I would appreciate any advise I can get. Thanks
