The Keyless digital lock is designed to operate a nightlatch, so for this particular product you do have all the components you require. You could also fit a separate Mortice lock to the door for added security, but this would operate separately to the Keyless lock.

This version is keypad operated only, the key tags or cards are compatible for use with the product product product YL-YD-01-CON-NOMOD-CH.

This particular lock will indeed operate a night latch only. I would recommend looking at the product COD-CL425-SS for a coded mortice lock. Please note that you should check that your door thickness is suitable to accommodate both these types of locks.

The button used to begin the process of changing your code is in the battery compartment on the inside of the door. The original code is not required to change the code but someone would need to be inside your property to access the battery compartment.

The code can be changed in 6 easy steps. Please see page 9 of the User Guide to see how to do it.

Unfortunately the keyfobs are not compatible with this model. I would consider the Yale Keyless Connected Ready - Chrome which can be operated with the Yale Smart Lock Remote Keyfob.

This lock is supplied with a plate for the lock to be fitted to the door. The keep supplied with the lock should be fitted to the door frame for the lock to function.

The Keyless Digital lock is designed to operate a night latch so you will need one, in this version the Yale Y3 Nightlatch is included. The purpose of a night latch is to hold the door closed and locked using the latch when the door is shut. The latch is then withdrawn into the casing when you enter your access code and turn the knob thus allowing you to open the door.

The lock is simple to install and supplied with installation instructions. We would recommend to remove the night latch as the lock comes with one.

This lock has a code free access option via a latch holdback feature which would allow people to access the building without entering a code, this feature can then be disabled and the lock would engage requiring the correct code being entered to unlock it.

The smart modules can only be added to the new Connected Ready Keyless Locks and cannot be added to the older versions of this lock.

The Keyless Digital Lock Satin Nickel (Satin Nickel) would be most suitable, but this does not include the Y3 Nightlatch. You would need to order Yale Y3 - Standard Nightlatch (60mm) as a separate item, but the Nightlatch is not availbale in a satin finish. This can be fitted to doors between 35mm-65mm in thickness so your 45mm door should be fine.

The door can be locked from the inside using the snib button on the Y3 nightlatch. However, this can be overridden by entering the correct code on the keypad on the external side.

The front part of the lock would just about fit but there would be a problem with the Y3 nightlatch which is 93mm deep and therefore too large for the space that you have. You may have to look at our range of mechanical digital door locks along with a 50mm latch which can be purchased as an option.
