    As above , alarm goes off maybe once a month , when it does the both key fobs remote stop working, I have to re teach each remote ie number 1 and 2 devices for the fobs to work again, I thought it might be the battery on the car so I replaced that but it still goes off, I am at a loss ???

    this happened to me,but on most eves, the battries are going in the siren.
    managed to remove tuppaware sub ect (mine has amp removed and sub driver) and locate siren.
    just behind cluster and held in with one bolt.

    since removed siren its not happened once,just need to carefully open it some how and rig in some 3.2 rechargeble battries.

    the car locks and seems fine! anyhow when alarm was going off nobody heard it :O

    Mine kept going off at random ... It's a cab I didn't realise the sensor is in the center console ....
    Had a handful of £ coins in the armrest ( car park money ! ) and the sensor was confused took them out all good now !
