I'm fitting an external key safe. Should I drill the wall plugs into the mortar joints or into the red hollow brick?
Definitely in to the brick and as many as possible @Bondy2 as this will provide the most secure fixture to the wall over mortar.

Hi @Bondy2,
Wall plugs work by expanding. If they are used in the mortar joints, the mortar will crack and fall out.
Definitely follow @Nailbag's advice here.
Let me know if you have any other questions.
