Hello and welcome to JustAnswer!

The problem could be with the vehicle but it's almost surely a failure of the fob itself.

The first thing that should be done is check or replace the battery. If you have a digital voltmeter you could test the battery's voltage.

If the battery is good or replacing it doesn't change anything then the next step will be to have the fob tested to see if it is transmitting. If not then the will need to be replaced. Most big chain parts stores such as Autozone will test fobs for free.
