I spoke too soon; it was working yesterday however it went off last night at 5:30am
I tried stopping it by pressing the button on the fob but nothing happened and I had to wait for it to stop by itself; the noise eventually stopped but the hazards were still flashing for a fairly long time.
So this morning I went out to see what's what and again the fob did nothing (although the light was working) so I had to manually unlock it, which set the alarm off, and then switch it off at the siren.
I noticed the bonnet switch connections were pretty cruddy (maybe the cause of the alarm going off that night?) so cleaned them up, switched the siren back 'on' again and still nothing. The fob just doesn't seem to be doing anything whereas is was yesterday.
Am I right in thinking there is a battery in the siren? but I'm guessing that's fine as it has no trouble deafening me and annoying the neighbours but can a weak battery in the fob cause this? As I say the little red LED still works but could the signal just not be strong enough?
Any help muchos appreciated
