Rated 4 out of 5 by from Great Lock-Manual not so good Bought this lock to ensure security of my workshop door, which although 44mm thick is 'only' redwood with narrow stiles and I feared the fitting of a mortise lock would take far too much material from the door and compromise the integrity of the door stile. I bought the 40 mm set back model and all looked tickety boo on opening and inspecting the contents of the box. The design of the lock appears excellent (it has BS accreditation after all) and it is a weighty item. British made too, apparently. The price is astronomiclly high for such a product in my opinon and on the face of it does not represent value for money - unless you have an attempted break-in and the device holds up - in which case the value rises exponentially. The instructions are....compromised at best and shockingly poor at worst. If you fit the lock to a right hand hung door then the instructions conveniently omit to tell you how to fit a primary component. On the face of it, what you have to do is impossible. The answer is to use the key to rotate the lock barrel. But that is a secret Yale do not wish to share with you. Their templates leave a little to be desired too. Luckily this is not my first walk in the park and after a degree of fettling and trial and error, the lock was fitted. An excellent product, potentially let down by poor installation instructions and a high price point. Despite the negatives, the product can be recommended. Very difficult to comment on reliability as it has just been fitted. I think all of Screwfix's reviewer have this issue

Rated 5 out of 5 by from Best you can get Have fitted a number of these night latches over the years and the quality of the Yale make goes without question. Just bear in mind that should you need to get out of the property in an emergency you will need a key readily at hand if locked from the inside. If replacing an existing lock you may have to cut wood out as these are heavier build .

Rated 4 out of 5 by from Great until it fails I fitted one of these locks to my door and it worked very well for quite some time. BUT the lock mechanism broke so that although the handle would turn or the key would turn the lock wouldn't open. So OK replace the lock! Because the lock failed when the door was in the shut position I couldn't access the screws on the edge of the door to remove/replace it. I had to grind off the hinges and open the door the wrong way around and then replace the lock and hinges and rehang the door.

Rated 5 out of 5 by from Nice replacement nightlatch Bought as replacement. Does the job and nice finish. Can be locked from inside for extra security. However this means if you lose a key and need to change keys you have to replace the whole lock not just the barrel. Only 3 keys are provided.

Can the cylinder lock be replaced by itself?

Can you purchase a replacement cylinder lock as it looks different size to the usual style. Thanks

Outward opening door

Hi will this work for an outward opening door?
Asked by: bush6
Hi Bush, thank you for your message. I am afraid that for PBS Night Latches you are unable to reverse the bolt for an outward opening door unfortunately. Apologies for the inconvenience. Regards, Yale.

Unlock from inside

I have a bad habit of leaving for work early and double locking my current Yale Lock from the outside as I leave. I wanted to ask, if I do lock the door from the outside, can it be u locked from the inside with the Key?
Asked by: Hass123
Hello, For this lock it is auto-deadlocking , upon closing the door. Someone can always open the door from the inside by using the keys. Thank you

Can this be used outdoors on a garden gate?

Asked by: Quasim
Hello, Thanks for the message. This lock is not weatherproof, and is only designed to be mounted on the internal side of a door where the lock body will not be exposed to the elements. Thanks, Yale.
