Scottish Elises

Does anyone have any idea why my alarm is beeping when i go to arm it,
it started doing it the other day and i thought it was because i had left the interior light on but nothing seems to be left on and its still doing it ? I know it will be something stupid but I cant figure it out
Oh and its an early S2 with the button on the key

Door sensor ? try giving the boot a push down

I think it must have something to do with the door sensors but its dark now and cant get a proper look at them .
When I slam the door shut the indicators flash ? Does this help?

Mine is doing the same, think it is water in the alarm/ wiring after driving home last week through flooded roads. Was beeping every time I tried to set it . Stopped doing it a couple of days ago and started again yesterday after a heavy downpour.

Its receiving a sensor error.....motor spark required!
My elise need a new sensor at boot last year....my current car needed new control unit and rewired!
