I just noticed this and wondered if it is the same for everyone else or a part of my car's personality, and don't recall seeing it talked before or in the manual. When I lock the car with a key fob, the red light on it and the other fob starts fast blinking for a minute or two as long as they are in range of the car. Move them out of range and they stop, bring them back into range and they start again, and then eventually stop altogether.
At first I thought it was a bug or something wrong, but now I can see a little benefit in that you can use it to see if you locked the car as you are walking away....something I seem to find myself forgetting more and more!
