Want to add extra security to front and back doors.

[Dande]

Hey guys.

I just moved into a house a few months back and I am not totally happy with the door locks and was hoping to add more but I am not sure what would be best which is why I am here.

The back door is pvc and the front is composite? Well it has a plastic/pvc back where i would have to attach a lock to.

What sturdy locks can I add please and is it ok to drill or screw into these doors? Tia

Please show us the doors, and the detail of your existing locks, including the outside keyhole, and the nearness of the letterbox to the internal handle.

You can use "upload a file" to add pics

I got these 2 pics, I wanted to add locks in addition to these rather than change them if possible.

Those are pictures of the door handles. Look at the edge of the door and you will see parts of the lock.

The letterbox is relevant because a simple tool can be inserted to operate the internal handle or key.

The external keyhole is relevant because some lock barrels can be easily broken or pulled out.

Hi,

The first picture shows an outward opening door? - this might also have an issue with just prising the door off of the hinges (depending on the type)!
Some hinge bolts and receivers may be of benefit
