Yale P-2-BLX-PB-40 Double Locking Nightlatch, High Security can be locked from inside with key, Brasslux, 40 mm

Made from cast bronze, this lock is very solid - you know it's going to protect your door. Fitting it is simple - in my case I was replacing a different lock, so didn't have to create the mortices. I offered up the template, drilled 4 holes in the right place, screwed on the back-plate, then positioned the strike plate on the door frame (I did have to enlarge the mortice for this, but no big issue. After cutting the new cylinder rod to fit, I fitted the cylinder, then used the two stubby brass screws to attach the main body. In use you can feel the weight of the mechanism and it certainly feels solid, secure and high quality. You can deadlock the inner latch using the key, which prevents it being opened from the inside. In addition, it has a strike-plate deadbolt - when the door is closed, it's not possible to shim the latch using a thin, flexible piece of plastic or metal. Superb.

Excellent lock for glazed front doors. Easy to Install and looks great.

The product is good, but I might have dropped one scrub screw and can’t fit it!! any chance of getting one anywhere please?

It’s a direct replacement for my old one that has lasted 40+ years. The old one is still going strong but we’ve changed from brass to chrome door furniture. Just hope the new one lasts like the old one (although I don’t think I’ll be around to find out!).

Does what we want it to

Firstly and sadly i saw no way of contacting the seller of this item to make this comment.This was bought as a replacement for an existing night latch. At the time of purchase it was considerably more expensive than shown now (now £31; paid £51). However, that is not the basis of my comment. The bottom latch lock doesn't work and the package looked like this had been previously been sent back, probably because the latch didn't work.Having said that the Lock part is fine, (and easy to fit for us as we already had a backplate, and keep from the one that we were replacing) but for the money paid frankly i would have expected a fully functioning product. Since we hardly ever used the latch i dont intend to go through the hassle of returning but i am disappointed nonetheless.

Nice and solidly built, clear instructions (do read them through - if you install one part the wrong way around (which still fits) when mounting the cylinder a future step is impossible. Also a hacksaw is needed for trimming the connecting bar - it's too strong for nippers / pliers. Shame it only comes with 2 keys and the required blanks for extras are expensive.

Do not buy this lock. The design is compromised severely - we’re on our second one from Yale and it starts sticking requiring the door to be slammed shut quite abruptly.Customer service from them are now getting stroppy and requesting all sorts of dimensions on latch clearance despite being shown a video of the malfunction.
