the keyless remote i have is from original factory, but it isnt the 2 button type which have "lock" and "unlock" buttons

the one i got has 3 buttons, "lock & unlock" both on 1 button, "trunk" button, and a "stop" button
press "lock & unlock" + "trunk" = engine remote start
press "stop" button to stop

anyways i dunno if anyone have the keyless remote like mine
according from the manual, to do a confirmation function (for the horn and signal)
has to do with two separated "lock" and "unlock" buttons
how am i gonna do mine now??

thanks in advance
