Keyless Entry and horn

[roids87]

How can i get my keyless entry system to honk my horn when i lock my car? i have a '98 4door GT, aLso is it possible to make my lights flash as well? It's really kinda of annoying to have to get so close to the car that i have to hear the doors lock so that i know they do. and is there anyway to increase the range in my remote? right now i have to be around 10FT away for it to work.

you could get an aftermarket alarm system with the keyless entry feature on it, some can honk the horn and some will make a beep noise

Some of the GM cars have the ability to change some limited parts of the keyless systems. I am not sure what that would be for your car though. On the range, nope. You have about all the range an OEM unit would have.
