alarm after re-connecting battery

[irvind]

The Blue Flash was laid up over the winter and the battery went flat, (unsurprisingly...) so I've charged it back up, but the alarm is going off and I've no
idea how to stop it.
I think it's the factory alarm, there's a broken key-fob which I've never used, and an immobiliser which is a little plastic dongle-type thing that plugs in under the dash. The car started fine, but so did the alarm.....
Any ideas? It's not MOT'd or taxed so I don't want to be running around in it taking it to get this looked at....

assumming the keyfobs not working at all , try locking it with the key, or disable the siren under the bonnet if applicable, try getting some batteries in the fob and hold the button down to see if it can re-sync with the car

Hi Eric,

Thanks for the reply.
I've been too busy to do much, but tonight tried locking and unlocking the door to no avail, the alarm kept going.
The button on the key fob is broken, so I don't think there's any point in trying any batteries in there. I've never used the key fob since I've had the car anyway, so I'm not even sure it's part of an alarm system.

Should I try disconnecting the fuse maybe?

Just to close this thread, I got a mobile auto-electrician out who disconnected the old alarm, an aftermarket Meta. No more siren.
Booked for MOT on Monday.
