These times call for affordable and reliable home security solutions.
When we lock the door and remove the key, a burglar can easily insert a duplicate key made using modern methods.
Leaving the key in the lock makes things much easier for an intruder, as they can use a special tool to turn our own key from the outside and open the door.
The "Crocodile" device immobilizes the key at a 45° angle, making it impossible to insert a duplicate key or turn our key from the outside.
This renders the door completely burglar-proof; the only way to gain entry would be to tear down the entire door, frame and all.
For cylinder locks, it significantly hinders attempts to snap the cylinder's retaining screw.
In the event of a fire or earthquake, having the key already in the lock allows for a much quicker and easier escape.
