After purchasing a 2010 Ford Edge Limited just a few weeks ago, I noticed only two lights (essentially 4 numbers) light up. Our 1999 Ford Explorer Limited had the keypad and all keypad lights lit up. Could this be a bad fuse or a few bad fuses...something I can fix myself or shall I take it to the dealer for a warranty issue since it's under the 3 years and 26,000 miles? Also, is there a function on these new keypads to open the hatch?
