Corolla L Keyless Entry Addition

I've searched the forum a few times and have seen people post that they added aftermarket keyless entry systems to their base model Corolla L. With the 2018 Corolla L is there a way to add OEM keyless entry access to the car? I've seen some post mention that the car doesn't have a certain module to support the factory keyless entry, other people mentioned that it did, so I'm a bit confused.
