Disable deadlocking mechanism?
I needed to buy a Yale 89 night latch in a hurry, to replace a broken
one. The only one available was one with a deadlocking facility. This is the only exit from a flat, so it's possible somebody could get locked in. Does anyone know if it's possible to disable the deadlock on one of these? |

If it is the only exit, then it is the only way in. You can only deadlock it from the outside. But would a person leaving someone inside normally deadlock it? Theoretically possible, not much risk if sensibly managed. I suppose for a couple where one has dementia and is paranoid about locking up, it might not be a good idea. |

Surely there's a knob on the inside for deadlocking (and unlocking) on the inside? No. It's for glass doors (which this isn't). You turn the key on the outside, and it locks the whole mechanism inside the lock. I was just thinking there might be a small lug or something that can be removed inside the lock mechanism that stops this. I've emailed Yale, but it's unlikely they'll help. Otherwise, I'll have to buy a new lock, which is annoying but not the end of the world. Tim |

With a backup, not being used, hung somewhere like inside an airing cupboard, with an equally large tag. Fat lot of good that would be with a fire inside the flat with so much smoke you can't see where the hell you are going crawling around on the floor. |

That particular latch *ONLY* has a keyhole on the outside. The point of the spare was if someone manages to lose the other key (not coincident with a fire). Arguably it would be better to keep the spare outside the flat. If the latch had keyholes both sides, like many euro locks, then the relatively safe option is always to keep a key on the inside. You can do that with a eurolock because it has two cylinders. The other case that is *relatively* safe is if the flat is on the ground floor, and can be exited through a window. I suspect that with sufficient ingenuity, it might be possible to disable the deadlock after completely dismantling the unit, but that might not be a simple DIY job. I havn't looked, but I'd guess Yale don't publish drawings of the internals. As Tabs says, it is not an ideal situation (but it is what it is). I am just exploring mitigations. Whether it is necessary to throw the 89 away once something else is available is a matter of risk assessment. |

That particular latch *ONLY* has a keyhole on the outside. The point of the spare was if someone manages to lose the other key (not coincident with a fire). Arguably it would be better to keep the spare outside the flat. But you will have a significant risk if someone leaves the flat and deadlocks it using the key with someone inside. The spare key inside the flat would be useless even if it could be found with the fire blazing inside. If the latch had keyholes both sides, like many euro locks, then the relatively safe option is always to keep a key on the inside. You can do that with a eurolock because it has two cylinders. Still have the problem with actually finding the key when its pitch dark inside the flat going up in flames. And pointless having the key on a nail beside the lock where any burglar can use it. The other case that is *relatively* safe is if the flat is on the ground floor, and can be exited through a window. I suspect that with sufficient ingenuity, it might be possible to disable the deadlock after completely dismantling the unit, but that might not be a simple DIY job. I havn't looked, but I'd guess Yale don't publish drawings of the internals. But someone may have youtubed it or just have done a teardown. As Tabs says, it is not an ideal situation (but it is what it is). I am just exploring mitigations. Whether it is necessary to throw the 89 away once something else is available is a matter of risk assessment. Silly to take a risk with something that important unless its a ground floor flat. Even if it is, not a great idea to require someone like child to have to think of using the window. And kids have been known to set fire to a flat playing with matches. I wouldnt risk it myself. |
