I assume this is a remote for a car / van (you don't say).

You don't say make or model either.

It could be that the remote needs resynchronising with the car (also called programming).

Just do a Google search for "MAKE MODEL Remote Program" and you should find plenty of results. Just replace MAKE and MODEL with the relevant words for your car
