There may be a fault in the Alarm system or Body Control Module, BCM.
I am providing you with its set operation functions and what requirements must be met for everything to work and then what to expect to see when it is working right.
Diagrams of the locations of all components and anything else necassary.
The first thing to do is to have the trouble codes checked and replace the battery in the Remote Key fob. Advance Auto and Auto Zone will pull the trouble codes for free. This will tell you if one of the components has failed.
If no codes are present. There are some diagnostic suggestions. However the other thing to do is check connections to componets for corrosion, loose terminals or any problems that would keep signal from reaching it.
From there the grounds for the components would need to be checked.
