Yale High Security Nightlatch

If your door cannot support a mortice lock or if you’d like an additional layer of security for your door, this nightlatch could be the ideal solution. Commonly named ‘Yale locks’ after the company who make them, these high security nightlatches are very robust and versatile. The latch will automatically deadlock when the door is closed unless the lock has been manually held back by using the ‘snib’ on the inside.


We can provide this lock with or without fitting by one of our highly trained, DBS-check locksmiths. Please note that a lock like this will lock your door automatically, so it’s important to have your key with you at all times. If you need to pop in and out and you’re not going out of sight of your front door, then the snib can be used to hold the latch back.


This lock is approved by Secured by Design, which is a police-led initiative aimed at ‘designing out’ crime. It ensures that products are designed and created with security in mind, making it very hard for criminals to overcome.
