Review: Works with Nuki Smart Locks - Good quality Yale lock, Easy and quick to install. Works great with the Nuki Smart Lock Pro (5th Generation). this was the may reason for buying this lock as it has the emergency function so the lock can operate with a key in Both ends of the lock at the same time. Not the most secure lock but a good price. Comes with plenty of keys, 5 to be exact but if you use it with a smart lock the keys will hardly ever be used, saying that they go into the lock easily.
Review: Excellent value "emergency function" barrel - This seems a high quality lock with the emergency function that allows it to be opened with a key from outside, with a key inserted inside. Other similar barrels from other makers are available but only at multiples of the price paid. Key is inserted horizontally and is a little more fiddly than a traditional Yale, but this seems common to the competition. 5 keys supplied a bonus. Fitted easily. Limited barrel lengths available however.

## Features

- 10 pins on 2 axes (60,000 variations) with high lock pick and D shock protection
- Drill protection thanks to the pin made of hardened steel
- Protection against break-in of the protruding cylinder part (anti-snap)

The set is individual (unique) we do not have additional keys.
Additional keys can be made by presenting a security card. 
Locksmith services are the services you should go to.
Kind regards,
