By pressing this button, you can open the fob and reveal a key that you can use to unlock your car.
Another sign that your fob's batteries are dying is the fact that you have to be much closer to your car in order to open and lock it than you did before. The transmitter of the fob loses power when its battery dies. This limits its range.
Replacing the battery is straightforward and relatively inexpensive. You'll need to purchase a button-cell battery (which resembles a small silver coin) and then follow the instructions in the user manual to remove the old battery. Replace the battery in the exact direction as the old one (the positive side facing up toward the buttons). Test the lock/unlock and start functions of the fob after reassembling it to ensure the new battery is installed correctly.

In the rarest of cases it could be the case that the issue isn't with your key fob, but rather with the vehicle's receiver or electronic components. If you have an inductive backup system, you can test it by opening the door using a physical key and then start the car with the inductive backup (if available). If your physical key doesn't open or start your vehicle then a mechanic should inspect the receiver and electronic components of your car to see whether they're working properly.
