Everyone’s had it happen: The postman rings the front doorbell and you take in a parcel. Uh oh! The door accidentally locks itself behind you and the key is stuck from the inside.
Now you're in a pickle. With a built-in emergency function in your door cylinder, you can easily open the door from the outside with a replacement key - even if the key is in the lock.

What does emergency function mean in a door cylinder?
Thanks to a special technical structure inside, lock cylinders with an emergency function can be locked from the opposite side with a second corresponding key even when a key is in the lock on the other side.
This makes it easy, for example, to open the flat door with a replacement key if you have accidentally locked yourself out and the key is still inserted on the inside of the door. In the case of door cylinders without this feature, a professional locksmith has to open the door when the key inserted inside blocks the cylinder. This comes with considerable costs.
Save lives in an emergency
As the name suggests, however, the function is also very helpful in dangerous situations. If a person inside the flat needs help and can no longer reach the front door on their own, a door cylinder with the emergency function can save lives in an emergency, since the door can be opened despite the key being in the lock inside.
How about a smart door lock?
If your lock cylinder has an emergency function, you can retrofit our smart door lock.
Simply swipe on the smartphone and the front door opens. Or open the neighbour's door to water the flowers while they’re on holiday. All this is possible with our HomeTec Pro Bluetooth® system.
