Fob issue

What is your question?

Bought my car Dec 2016. Started to notice in Jan of 2017 my FOB didnt always work. Started with remote start,then locking and unlocking doors. Now it doesn't work at all. Thought it was battery so I replaced. Worked intermittent for a week. Now doesn't work at all. Suggestions or am I not the only one? Btw...has happened with both FOBS
