Also important to do when it does fail. Things change by model and year. My 2013 VW Golf only is necessary to open and close the door locks. The key fob has a key which is always used to start the car.
However, it is also used to unlock the door once you locate the hidden key slot under a cap on the door handle. Not a big deal unless you don't know about the hidden slot.
Each car has its own technique. Learn yours now. Learn where the spare key is located in some FOBs. Learn what kind of battery is used and how to replace . Learn by changing now and then keep an accessible spare.
Don't read this and then wait until it happens.
