No verb for “to lock”?

I was surprised to learn that there isn’t a verb “to lock” in Spanish. It seems to be usually translated as “cerrar con llave” (to close with key).

Of course I know that languages don’t translate word-for-word. But this is the first one I’ve encountered where I’m really surprised by because it’s such a common thing to need to do.

Is there any linguistic reason for this, or it’s just one of those things?
