When ordering multiple Keyed Alike locks, only 1 set of keys are provided as all additional locks are made to work from that key.

If ordering 4 or more keyed alike locks you can have them set up as different groups. If Required: Let us know the details in the "Specific Key Requirements" field above.

Each group of locks will then receive keys.

The Yale 91 Rim Nightlatch Case Only is a standard security locking solution designed for timber doors. This replacement case is ideal for upgrading or repairing existing installations where the external cylinder remains functional. It features a 60mm backset, which is the traditional measurement from the edge of the door to the centre of the cylinder hole.

Operationally, the latchbolt is withdrawn from the inside via the lever handle and from the outside by a standard rim cylinder (available separately). A key feature of the Yale 91 is the internal snib, which allows the user to hold the bolt in the retracted position, preventing the door from locking when closed. This model is non-deadlocking, meaning that while the door is latched, it can always be opened from the outside using a key, providing consistent access for authorised users.

The latch is fully reversible, making it compatible with both left-handed and right-handed inward opening doors. For outward opening doors, a separate reverse strike may be required. This case is suitable for doors with a thickness between 32mm and 57mm and is commonly used in residential properties as a secondary security measure alongside a mortice deadlock.

FAQs

No unfortunately not, the BS3621 nightlatches can not be reversed. The only way to do this is to install a standard nightlatch from our outward opening nightlatch section and then also install a BS3621 deadlock. This deadlock will give you the insurance rating required.

You need to make sure the lock you fit is NON deadlocking. This means that you can not lock people into the property. There are a few nightlatches designed for these doors. The best is the Yale PBS3 or PBS4 or a more standard model would be the Yale 88 or 84.

The best locks for these would be the a rollerbolt style lock with a masterkeyed cylinder. I would not recommend installing a standard Nightlatch on these doors as the tenants can lock themselves out if they close the door behind them. We can supply these locks for you on a masterkey if you require or keyed differ if you would prefer.

The backset on these locks is the distance from the edge of the door to the center of the Rim Cylinder. This is the large 32mm hole drilled through the door. There are 2 main sizes of these, 60mm or 40mm. Easiest way to find out what you have is to measure from outside of the door from the edge to the center of the keyhole. If you have a solid door you should use the 60mm backset locks, if you have a glass panelled door then you may need to use the 40mm backset. If your current lock is 50mm backset you will need to see our Union locks as only Union made a 50mm backset lock in the past.

There are different levels of security you can have with all locks. The standard locks (i.e. Yale 77, Yale 88) , then the mid level locks which can be key deadlocked from outside ( Yale 89, Union nightlatches). The double locking versions are only suitable for homes with other means of exit as you can lock people inside the house if not careful.

All the extra keys for the locks are cut to the specific locks that have been ordered.

With most locks that are altered to make them keyed alike you will only get 1 x set of keys with them. So if the locks normally come with 2 you will only get 2 keys total and if they come with 3 keys you will only get 3 x keys total when ordered keyed alike.

No, this is a 'Case Only' unit. It is designed as a replacement for an existing Yale 91 nightlatch, allowing you to retain your current cylinder and keys. This is an ideal solution for upgrading or repairing an existing installation where only the lock body is damaged or worn.

Yes, the latchbolt is fully reversible on-site to suit your door's orientation. Please note that for outward-opening doors, a separate reverse strike component is typically required to ensure a secure fit and proper operation.

Yes, the internal case features a slide button, commonly referred to as a snib. This allows you to hold the latchbolt in the retracted position, which prevents the door from locking automatically when it is closed.

No, this specific Yale 91 model cannot be deadlocked from the inside. This safety feature ensures that entry can always be gained from the outside using a key, preventing individuals from being accidentally locked out or trapped inside.
