2004 Saab 9-3

Evening all

I’m looking at buying a 2004 Saab 9-3. The guy has said the fob doesn’t work and he just leaves it unlocked and that “there is no way to lock with the key”.

I was under the impression most cars like this had a lock on the drivers door, under a cover on the handle? Is this correct that there is no way to lock it with the key?

Thanks!
