Help please

thanks for the link...well i took the siren out and yes the batteries had corroded pretty badly so i whipped the unit out got it apart and am getting some simillar batteries for it...but,,,,when i lock it witht he remote and leave it sometimes the flashers go off....im confused...

i changed the batteries in the remote and it seems really slow for the remote to lock or unlock the car...strange..as the siren is not in the car would this cause the flashers to go off..

The thing that is worrying me is that this never happend before MIJ messed about with my battery when the did some welding on the new exhaust.............any ideas....
