After writing back the new values, you have to do a manual reset of the three modules (or remove battery for a while). After reseting RTM the original keys won't work anymore (beside in backup slot), but now you can use the new key to open / close / start and remote start the car.
To switch back to default keys, just set RTM back to 1 and do a reset.
