I wouldn't fuck about with it tbh mate. I've got remote start and all sorts going on in mine so I generally don't like to fuck about with it. The other day I was doing a dash diagnostic and because I turned ignition on and off 3 times it went into emergency override mode . I've never tried it but with the KOER, if you press the lock button on the remote it should lock the doors *I think* but if you've unlocked and un immobilized with one fob (primary one) it might not like the fact you are trying to use the second fob with the engine running and ignition on. You might get yourself into all sorts of shit.
