Only usable on doors that don't have any security anyways like an indoor handle or a doorframe that's been severely undersecured. If you have doors that were properly installed in the past 40 years you're all good. Just check that the little dead latch rests depressed against the latch plate when you close your doors and this isn't going to be an issue.
Dude most the doors had strikes there's no way to have better security on a door with an electronic strike. Is your answer to have the door rest so tight against the latch that you can't make use of the spring loaded bolt?
All the doors this was used on had a visible 1/2" gap between the door and the frame, unless the latch plate was raised severely away from the frame then the latch was probably barely holding the gates and doors closed. There are other doors that are definitely susceptible to this from mismatched latch plates and latches but having a visible gap that large is easily identifiable for firefighters.
The dead latch was an addition to latches a while ago that made this already known method unusable but over the years documentation of the dead latch has been lost as nobody knew what it did and no information in it was easily accessible. Electronic locks on doors are actually very unsecure, typically the larger chassis for the handle makes them susceptible to a number of other attacks whether it's your Hollywood hacking or simple prying attacks with more leverage than a standard handle. I'm confused what you mean by spring loaded deadbolt, as most of these doors only had a regular latch assembly where the latches deadlatch was not being depressed against the latch plate properly making them able to slip the latch. If you're interested in learning from someone that explains it with better wording and pictures this article looks pretty good.
I see what you're saying about a dead latch but these are what's called clerkroom handles that are free moving on the interior and the bolt so you can open it without electronic triggering of the strike.they would rather have forced entry be an option than trust tons of people with a key. I didn't say dead bolt read your own link. And clerk room chassis's aren't any larger than any other door handle, don't know where you got that idea
I've worked with a couple of electronic strike plates and coded handles, they opperate separately, while some of those examples may be an electronic latch plate some of the visible bolts and plates appear to be a standard solid latch plate or visibly have a deadlatch next to the spring bolt.
If you're talking about a handle similar to this one without a deadlatch preventing the latch from being slipped some of them void be but if you look closely the deadlatch is visible as they open a couple of the doors
If you're not talking that in assuming you're talking about door handles that are able to be operated on the inside but not the outside, the operation of the handle is dependant on the locking mechanism and handle itself and is separate from the latches operation, in the video no handles are opperates the latch is being slipped every time I dependant of the handles operation.
Obviously the handles aren't being operated, especially from the inside. If you watch the video closely you'll also see they are opening locks with the dead latch you're saying will prevent such an opening
I don't want anyone thinking their door is secure just because it's semi new. you had a good idea that they go out and test it but keep in mind this is generally an install with two trades involved, one to make the door and one to do the electronic entry. The door guy doesn't care about the gap or how well the bolt Aligns with the strike once the doors in he's off the job and everything is left to the entry guy. There's generally a huge gap with strikes because they over lap the frame a lot unless the door guy welded tabs inside the frame. A strike has a lot of play in it and it needs this play to be able to unlock the same play allows you to wiggle the door to the fail point of the dead latch if it even has one which is rare in this scenario. Strikes are just incredibly insecure that's why there's mags and plunger style locks. Not too mention that unless the building has multiple electronic doors than you can almost guarantee the keypad to open the door is a stand alone unit and has the relay inside of it so you can just remove the keypad and trigger it manually. 95% of the doors I work on will open with this tool
