2001 Sirion GTvi 1.3L manual

Forum: 

Left indicator out of the blue came on and stayed on - not flashing. Disconnected battery. When it was reconnected, battery was flat.
Roadside repair started the car and checked indicator, apparently the hazard may have jammed - he said it happens because they're not used much. The indicator works perfectly now, does not stay on when car off and key removed.
The fob now will not lock/unlock the car. Changed batteries in both fobs. Followed directions found in the forum to discharge fob and put batteries back in. Key in drivers door locks/unlocks the car.
Help to solve this greatly appreciated as its my daughters car and she's studying 2hours from home.
