Latio comes with immobiliser, no alarm (unless retrofitted)
to confirm that there is no alarm, try this :
1. wind down your window
2. lock your car as usual, using the i-key
3. reach in and manually unlock the door
4. open the door using the door handle (outside) or lever (inside the door)
then see if there is an alarm sounding when you open the door
note - car will not be able to start without the i-key in range => immobiliser
