To determine if the issue is with your battery or key fob, try the metal key inside the fob to unlock your car manually. If the car opens, the battery might be fine, and the fob is likely the issue. Alternatively, check your car's dashboard lights when you attempt to start the car; if they dim significantly or don't come on, your car's battery may be dead. For a definitive answer, consider replacing the key fob battery as a simple and cost-effective first step. It's a quick fix if that's the problem.
