Phantisy

I just bought a used 99 RL and we only received one master key. We didn't get the learning key or anything else and we need to get another key made. I talked to the dealer and I was told there is no way to get another key made without the learning key without replacing the key security system. Does anyone know different?

We actually have the gray valet key not the master. Is there a way to get a master key made without the key number plate?
