key fob megane II problems

hi. got an issue with my megane 2005 1.5dci.its with the key fob, it works fine starts car and locks etc but if I go near the car with the key fob the indicators come on randomly without pressing the buttons sometimes unlocking. i have to lock the car and retreat a distance and the indicators remain off like normal. but returning to the car and without pressing buttons creates the indicators to flash sometimes unlocking. i have noticed in recent days on getting in to the car it beeps twice, which i don't recall happening before but i don't tend to drive this car much (wifes)...any ideas, has anyone else experienced this any help
