Hello,

The first thing you need to make sure that the battery in the fob is good.
Overtime those battery will deplete and will need replacement.

If after a new battery the fob still does not work, it could either need to be programmed or the fob is faulty.
Another possibility is a bad keyless module that is in the vehicle.

Here is helpful guide on key fob programming:

Please let me know if you have any questions.
Thank you.
