second what dan says
my alarm was a £400 jobbie, cat one with al the mod cons etc available through gap security
the fitter did his job and i was pleased
until it went wrong, then he fobbed me off with "nothing to do with the alarm that your battery's gone flat/the central locking doesn't work/you can't unlock the car/it won't start/the windows won't go up/the sunfoor has stopped working" etc
subsequent inspections to get it sorted have cost me more than the alarm cost in the first place and it's hit and miss if it works or it doesn't as it's been wired inccorectly
the warranty wasn't worth wiping my arse with either as gap only pass the problem onto the installer and, to be honest, i can't be arsed to chase it up and am quiet happy to simply state that this is an issue and i would like it sorted with the bare minimum of fuss to me
anyway, thats it for the short rant from me

but yes, that toad one came up pretty good on a list a few times now
i still can't unlock the doors with the alarm as it only locks the doors so i've got to disarm the alarm, then use the original ford remote fob to unlock the car
