Hyundai Motor India — Hyundai Venue SX car lock/unlock sound is full blown horn.

I bought venue sx diesel last month, and figured out the door lock and unlock sound are just car horn sound and it is blaring like air horn and not able to be muted. I got ear pain due to this from the day 1. It honks once for locking and twice for unlocking. I took the car to dealership to get it muted but unfortunately they disagreed to do that and added it will void the warranty. And dealership agreed that other hyundai car models has mild sound and some models has option to mute it but especially venue there is no option and no support to mute it. I personally checked venue sx-o has a separate mild sound for lock/unlock but venue sx doesn't have mild sound instead of full blown horn. This differentiation was not mentioned anywhere when i bought.

As a common man, i am feeling bad for annoying neighbours by honking when lock and unlock and even some my neighbours are complaining. Dealership provided an irresponsible answer that do manual lock/unlock with keys like stone age, with that i am getting scratches near the keyhole and having heavy luggage in the hands, difficult to do manual key lock/unlock. This feature will definitely should be fixed with an option mute/unmute or mild sound like venue sx-o. Is there anyway to knock hyundai's attention or legal option to get it resolved.
