Anti-theft alarm?

Hi,
I took i20 Asta 1.2 Petrol.
In fact, its my first car.
Its a great car. Great feedback from my friends and colleagues.

But, I have an issue with Anti-theft alarm feature. When I lock with transmitter (remote key) it gets locked. After few minutes, if I try to open the door manually with the key, it does not make any noise.
Also, car does not make any noise when you lock it or unlock it using remote key.
Dealer says i20 Asta does not alarm.
Guys, please let me know your experience in this regard.

Thanks
Excellent car, Good fuel economy, Great styleAnti-theft alarm
