Part of it is because most automakers don’t bother to mention it and part of it is because very few of us take the time to find out. This is one of the more common hidden functions of many of today’s key fobs. Sure, you can go to your car and do all that by yourself, but you don’t have to if you have a key fob that can do the job for you. It’s a common occurrence, especially during the summer, but you can mitigate that by rolling down all the windows and opening the sunroof at the same time with the press of a single button. It’s a hot day and you know that the moment you get into your car, you’re going to feel like you’re inside an oven. Granted, not all key fobs have these features, but if yours has them and you don't know about it, now's as good a time as any to find out. Just make sure that when you do take the time to practice these features, you’re doing so from the safe confines of your homes. Check out a few examples of some nifty key fob features that you may not be aware of. The important thing is to know what these hidden features are, how to access them, and how to use them in a way that doesn’t become a source of frustration to car owners. Simply knowing these features opens up a world of convenience that car owners didn’t know existed.

These days, key fobs have a multitude of built-in features, some of which owners may not even be aware of. Gone are the days when key fobs could only start a car remotely or lock and unlock doors, and some of these key fobs can actually be quite expensive. And yet, key fobs have become critically important devices among car owners, in part because of the multitude of functions they now serve. They're small, light, and completely inconspicuous.
