Locking a Timber Back Door

I'm having a new half glazed door fitted to the back of the house. It's not overlooked so could be an easier target for a break-in so I want a good lock. Then someone muttered "multipoint lock".

I've trawled the net and found they can have hooks and/or rollers. Rollers have the advantage in my mind of pulling the door into the frame so it is less likely to warp. I've also spotted ERA do one that isn't a euro profile.

Can anyone advice please?

I have fitted a multi point lock to a wooden front door before, (only the once, wish I never said it tbh) had to cut a groove with a router in the door and went for one without roller cams because you cant hide the keeps.

Wether it was any better than putting a piece of metal behind the keep to reinforce the lockplate jamb I dont know.

Slide bolts would also keep the door warp free and combined with a motice lock, yale type latch and steel strip I cant see anyone having an easy time getting in.

A wooden back door? At least it will be better, stronger and cheaper than a plastic one.

mortice rack bolts top and bottom, and a BS sashlock, will do the trick and are easy to fit. A yale is not usual on a back door. Take the keys out when not in use and conceal them on a convenient hook.

I like 3 stainless hinges on an external door.

You can fit a kickstop reinforcer round the lock and at the frame if you think it is not very sturdy. If the door is fitted by a skilled joiner he can probably fit them quicker and neater than you.

If you can afford a hardwood door it will be stronger and last longer than a softwood one. If the doorframe is damaged or poor quality, change that as well.
