Duff alarm fob?

[BLUETHUNDER]

One of the alarm fobs lasted less than a day in my new ownership last week.It just suddenely stopped working.I e-mailed the previous owner as to know if he changed the batterys.Got a reply to say that that he replaced them two weeks prior to me picking it up with a replacement from Claremont.I thought they could still be duff,so went out and bought a couple just to be on the safe side.Tried both of them in it.But still no joy.I,ve tried all the methods in the manual,re-sync the keys and re-training the fob through the ignition still no joy?.Any ideas anyone.Out of interest how much would a new one cost?
