My car doors won’t unlock

What is your question?

I usually use the key fob to unlock the door but the car is no longer responding to the key fob and I was told, perhaps I should change the battery. I replaced the batteries in the key fob but the car doors will not unlock with me using it and the key will not turn in the car door to assist in unlocking either so I’m locked out the car. I’m not sure if the car battery is dead and that’s why it isn’t responding or an issue with the key fob itself.

How long has your 2005 Toyota Camry had this problem?
