I think you mean "why doesn't my key work to open or lock the doors?" If that IS what you mean, the key's battery sends a radio signal to the cars computer. The computer directs the door lock system to lock or unlock the doors, but it gets it energy to do that form the battery. Hence: Car battery dead - car's onboard computer cannot respond to directions from the key signal.
