Converting composite door so it cannot open from the outside

[nitr0uk]

Hello,

I have a composite door on my porch which currently opens from both sides without the use of a key.

You lock it in the normal way of lifting the handle and then using the key to lock, this can be done on both sides.

It has normal handles on both sides, similar to these;

Is there a way to convert this so when you close the door you cannot just open the door from the outside?

Thanks

Depends what lock its got, take the handles of and if you have 2 spindle holes you just need to gat a lever/pad handle, if it only has one spindle you may be able to use the same handle with a split spindle but that all depends if the multipoint offers split follower.
