Alarm alarm

S2 Exige- alarm went off for no reason last night so went out and turned it off. When I re-armed it, it locked ok and indicators flashed twice, but there was a continous beep afterwards. It now won’t arm without this beep (does go off after 30 secs). I guess it thinks somethings open- I can vouch for the doors and boot. Is it worth removing front access panels and re fitting?
Anyone else had this problem?
Appreciate any pointers.

I had some wierd stuff like that and the stack also stopped working (well dials did). I took all the fuses out and then put back and it fixed the issue (like a reboot i guess)
