DC5R alarm randomly goes off

[foujee]

Hey guys, my missus has a DC5R, every night the alarm seems to go off randomly for no apparent reason.

Is there any obvious reason why this may be happening ? or has this happened to any other DC5R owners out there?

Thanks, any help would be appreciated !:)

It's the original Honda alarm by the way, not an after market alarm.

Problem with sensor or battery might be low maybe
