Why would my car alarm go off

Tried re-synching keys again now that the door wiring/circuit has been repaired? Sorry mate, I'm really clutching at straws. Haven't a clue on electrical things tbh so forgive me if any of my offerings seem elementary :uhm:
 
right another up date , so i decide to look at passenger front door and sure enough 2 wire were slightly stripped in that door too so iv repaired them, then while i was packing my stuff away out of habit i pressed my fob and it worked!!!! yay but ....... the other fob was not working so tried re syncing that and now neither fob is working again lol but all doors are now opening when un-locking the car with the drivers door lock !!

****** off again now so given up for the night lol
 
Yes deffo happier now just annoying that summit as silly as the battery back up for the siren would cause so much hassle , stupid design too
 
How did you get to the siren box? I tried to get the trim off but it wasnt having it, i was cautious mind so does it need more force?
 
Yes buddy been fixed for weeks now no issues since!! Trim needs a few bolts/screws removed whole floor needs to come up side bit of the drivers rear seat cushion back seats flat down then about 3-4 screws holding it in then odd clips too
 
That's good, im gonna pray for decent weather tomorrow to tackle it. As the cars driving me up the wall. Cheers 👍
