The alarm on our '99 Corolla has gone crazy mental. Just keeps going off. The remote has no effect on it. Using the master key has no effect. I tried driving it for a bit, but the alarm continued to sound. Strangely, the lights/indicators are not flashing at all while the siren is sounding (this does happen when the alarm goes off as it's supposed to). Battery seems fine (all electrics on at once, elec windows go up and down at full speed).
I've disconnected the battery to stop the noise (ears blocked with cotton wool to cope with unreasonably loud alarm)
Anyone got any recommendations of someone in Sheffield who could fix this sort of problem?
