content: WTF!!!What were the designers even thinking with their single time-share brain cell? Isn't it obvious that you just *DON'T* put the 'brain' of an access control system in a location that is less secure than the area it controls?The *FAIL* isn't that relays can be activated by magnets, its that they control a critical circuit and are there in the first place to be activated. All the keypad should do is send well-encrypted button presses to the 'brain' which should be the secure side of the door, preferably in a physically locked, robust secure cabinet.

content: Not a first lock he opened with a magnet. While his videos show how to pick some locks, and might be used by crooks, ultimately he shows what locks are total crap that can be opened with a fork, or a piece of can.

content: ItNEVERceased to amaze me, when I worked in the security business for even large buildingsand enterprises, how even the SIMPLEST 'mechanical' means would 'circumvent' such Code-Pads etc!Like NOT CLEANING THEM REGULARLY!!! (What?). You walk up to some door access, and see say 4 buttonsthat are rubbed 'cleaner' than the rest! Say... 2,4,6,8. So you KNOW the code is either that, or say 4,6,8,2...or 2,6,8,4 etc etc. 30-secs later, your in!!! Believe me... CLEAN THE KEYPADS!!

Doesn't work though, when the 'pads' are 'Capacitive', or pick up 'RF' from your body!!I remember many years ago, when an Elevator was installed in a fairly remote/radio-quiet area. It used,(as a lot of lifts do/did) your body to act as an RF Aerial to detect button touches. However, there was solittle signal strength there, it didn't work!! Was fine in a City.

content: They also had thermal sensing buttons on lifts, did not work out well in a fire, where the lifts all came to the floor of the fire, and stayed open.As to the keypads, they are not secure, only really meant to keep opportunity low. Easy to tailgate most of those doors, or social engineer your way inside, and if there is an intercom you simply press all the buttons, you are almost guaranteed that somebody will let you inside without checking who you are.

content: Tailgating and not checking visitor credentials are social problems - sack a manager and a couple of 'peons' every month for failing to follow security procedures and most such problems go away. Of course that's not possible for residential buildings - if the residents don't want to pay for a manned security desk to handle access control, they'll only get an illusion of security.The heat sensing lift problem is obvious in hindsight, but as they presumably weren't rated for evacuation in case of fire, may even have saved lives! Of course from a fire-fighting perspective, it wasn't ideal to have the lift shaft compromised at the seat of the fire, possibly acting as a chimney, increasing the threat to higher floors and depending on the building layout drawing the fire towards an area that probably also contains the stairwell access.

In one of our major Prisons, I tested the maincontrol room by hitting the intercom saying "doors 16, 18, 22 & 24 thanks!". I heard Clunk Clunk Clunk Clunk.They were supposed to personally identify you on video, then one door opened/locked at a time. I could havebeen a prisoner, and walked outside! I detoured to the control room & told them off!! Complacency!!
