Hi guys :) I recently bought a Ford Fiesta (2003 model) but the remote locking doesn't work.

Frankly, I'm not willing to pay £125 for something so small. But I need the alarm because I've had it less than a month and it's already been vandalised. Unfortunately though, the alarm only activates when the car is double-locked, which you need the remote key for.

So what I'd like to do instead of replacing the key is adapt the alarm system so that it activates when I lock the car with the key. This way, the car's slightly safer, there's one less thing to go wrong, and I'm not paying disproportionately large amounts of money. Is this possible? Many thanks.

Its a perimeter alarm. Unless the vandals break in or pop the bonnet it won't help.

I used to have one and you could set the alarm by turning the key both ways.

As Jethro touches on, an alarm will unlikely prevent vandalism. Indeed, sadly, an alarm will unlikely prevent anything so I'd just do without if I were you.
