have a terzo and all of a sudden if i try to lock the car with the key fob, it locks the doors, but after about 30 seconds or so the alarm goes off!!

but i have noticed that when you press the keyfob button there is a high pitched noise from under the bonnet?

i am not very good with cars as i am a newbie.

but as it stands i cannot enable the alarm!!

Please can anyone help?

is the battery ok?

yeah no problems with the key fobs both are fine!

Is your bonnet pushbutton stuck? So the alarm thinks the bonnet is open?
