I saw many cars (top end) specially i20 and etc, their central locking sounds come through its horns. which sound premium.

after much research I found the solution hence sharing the details.

You can use this in any car of any model (preferably who are using dual horn) ... I will post video of this DIY.. but here I am posting a diagram to clear all doubts..

3. some car thimble

and some basic knowledge of car's horn wiring .. ( no issue you can show this diagram to car electrician too, he will do the needful)

Hi. That's a very clear explanation. But i'm encountering 1 problem.
When the alarm goes off the horn starts honking continuously. Also unlocking the car doesn't help. Any solution to bypass this? That the horns will work like a flasher when the alarm goes off.
