Bad key fob?

[Moomin_Man]

Ok, had my twingo for 3 weeks now.
In that time, the key fob has got worse and worse. I now have to stand next to the car to lock it.
Also, 1/3 times, the car lets out a high pitch tone when i lock or open it.
Is this to say that the battery needs changing?
Maybe the key fob has sat in a warehouse for too long?
Seems odd.

Its all to do with the alarm mine done it the other night. From memory its just the alarm setting

Isn't the beep when unlocking saying the alarm has been set off?! Need to look at an led to see why. Number of flashes or something. (says in the manual I think)

I'll be interested to see wgat the beep when locking means. I asked Karl about it at the weekend actually and he couldn't answer
