I guess it will be possible in the future someday to use random keys...
however for the horn I guess it's the submission key...
Look on the website mauzen sent, there is a "released" code somewhere lower on the site, copy this code and then you can use something like this:

Код:

if(RELEASED(KEY_SUBMISSION)){
if(IsPlayerInAnyVehicle(playerid)){
new v = GetVehicleID(playerid), Float:a;
GetVehicleZAngle(v, a);
SetVehicleZAngle(v, a);
}
}

this code at OnPlayerKeyStateChange or so...

(I don't know whether this works or not as I just wrote it up)
