Why doesn't my headlights come on when pressing the unlock button on my handheld keyless entry remote?

My headlights always came on after pressing the unlock button on my handheld keyless entry remote. I recently had my car battery replaced and now when I press the unlock button on the handheld keyless entry remote the headlights no longer come on. I cannot find anywhere in the car manual what controls this feature. Could a fuse be blown? If so, which fuse is it? This feature was nice, since it would light up the area in front of my car when I approached.

Thank You
