Horn Upon Locking

[mbavon2222]

Is there any way that the keyless entry could be made to sound the horn when you lock the doors? I'm used to my cars sounding the horn when the car is locked. 2009 GT.

There's a discussion of how to do it here, and at one time a member was selling kits but not any longer. It's for 1st gens but I imagine the 2009 would involve a similar process.
