Doing my head in...

 

Main Battery is fully charged (although have ordered a new one out of desperation). Key fobs work tidy, car opens, starts and runs but the alarm will not shut up ! Lock it again and the alarm subsides. As soon as you open with key or remotely the alarm goes off. I can only assume in the 4 months I wasn't using the car the sigma has forgotten the fobs ?

 

The central locking starting etc must be separate to the actual alarm. No amount of fob pressing once the ignition has started makes the alarm stop, You can pull the fuse but the indicators are still lighting up

Now the stupid part is the previous owner doesn't have the pin code and the after market radio wont allow the override I am told.

What options do I have ?  

 

Have already phoned the dealer who want £50 just to 'scan' the alarm system lol . I'm not stupid I know my way round cars, and this mythical scan is a proper pants pull down. I just don't have the alarm knowledge to fix this one. I hate Sigma :( 

Thanks in advance

Time to lube up for the dealer I guess :(
