Back in 1998 when i bought my current house, the insuranse company sent me a notice with the insurance form.
It stated.....If any of the following types of lock is installed, the insurance does not cover and then pictures of the keys, one of which was my exact key.
These were "simple" lever locks, you could buy the keys for them in any hardware store, i think there were about 30 different ones, so if you had a complete set and 3 minutes, you were guaranteed to get in.
My house was fitted with those, so i promptly changed the doors to something more modern and fitted those with RUKO system locks that had 2 rows of pins, they can not be bumped and picking is not for "everyone".
Those are so safe i would claim, that any thief would find an alternative way of getting in....Possibly just smashing a window.
He would offcourse then have to deal with the CCTV cameras and the burglar alarm. (Plus the fact that when the alarm goes off, the light in front of my house starts flashing red, the electric roller blinds will open, the light in the house will start flashing.....And after 30 seconds, all of the Sonos speakers in the house will go to max volume and start playing "Fortunate son, by Creedense Clearwater Revival" and after it finishes they will divide into some playing an internal alarm sound, some playing police radio chatter and some will say something to the effect of "Anti theft defence measures being deployed, please vacate the premises immideately, to prevent harm to people")
Oh and also a set of speakers in front of the house will play police car sirene sound to stress the thief, as he might think the police is very close and closing in.
Soon i will receive another 6 Hue lamps on posts, these will offcourse also be added to the "Red flashing light"
Did i go a bit overboard.....Maybe

(But it was extremely fun)
