[help] - rx300 2004
 

Hi, I was hoping someone might be able to help...
I have a 2004 RX300 and the Key Fob has stopped opening the doors, the light is flashing to say its transmitting but the doors don't unlock... I unlocked it with the key in the door and the alarm went off. I thought starting the engine with the key might stop the alarm. The engine started but the alarm continued. Has anyone ever encountered this, or has any ideas as to what is happening?
(to add insult to injury, I'm in France on holiday - I live in the UK - and I now can't drive the car!)
