Snip dropped on my lock, what can I do?
The snip is the little round button on a nightlatch. This is normally used to leave a door open (‘on the latch’) and on some nightlatches can be used to deadlock the door at night time to prevent anyone ‘slipping’ the lock with plastic.
We always try to advise not to use the snib at night time unless it is the only lock that is on your door. Ideally using your mortice deadlock, thumbturn lock or tower bolt should keep you secure however it is very common that problems do occur with the cheaper variety of rim nightlatches with age.
As accredited London Locksmiths we see this about once a month where someone is locked out of their property because their key will not open their lock. There are not too many ways of opening the lock and on many occasions the lock has to be destroyed. We will always recommend using a auto deadlocking nightlatch as a replacement as this will offer both security and the ability to snib a door open, you will always be able to open the lock from the outside if you have a key.
An auto deadlocking Nightlatch can be as cheap as £40.00 and are worth the investment from a convenience and a security point of view. London Locksmiths will be able to recommend a basic auto deadlocking nightlatch as well as higher security ones, there are also a small amount that comply with BS3621 (British Standard Insurance approved locks)
