The key fob's 12 volt battery is crucial to powering all on-board electronics including the remote keyless system as well as the central locking system. If the battery is defective or has run out of charge, all of the electronic components on board will cease to function and the remote keyless system will not work. To test the battery, disconnect the negative cable and then the positive cable for a short time. This will eliminate the remaining electricity from the circuit, and reset it. The remote keyless system will function again.
If you have a spare key fob that is working, it is worth trying to re-program the original key fob to see whether this resolves the issue.
