meta alarm keyfob battery?
not sure if this has been mentioned before, i did a search but couldn't find the answer i was looking for. basically i noticed my alarm keyfob wasn't working too well so i split it to have a look at the battery inside so i could get another. luckily i ordered a pack of 5 coz when i went to change them i noticed there was 2x cr1220 batteries in the little plastic circular holder. Put 2 new batteries in & hey tesco! it worked. is this normal, is the meta alarm a factory alarm on the gtv? also i've got what looks like the same keyfob on my bike alarm which has no batteries in but i've tried putting 2 batteries in that but it doesn't work?
