eBay electric lock (or drop mechanism)

Ah yes, I’ve taken one of these apart before, they are a pain in the butt to put back together, it’s kind of like a puzzle, but it is not anywhere near as complicated as locking mechanisms I’ve worked on before, like mortise cylinder mechanisms, if you don’t take a picture of it assembled before you take it apart you have no hope of ever putting it back together

Our Amazon lockers are usually outside. Sometimes placed outside a bank, but more commonly at a convenience store (small petrol store). Since most are in remote locations and not noticed (even "hidden"), they definitely have cameras watching them.

This takes me back to working within Racal Defence's Research & Development Establishments, with their different coloured coded Card Keys for various areas. As soon as the principle of the locks was explained to me, I set about making my own.

JST SM do appear to be the magic keywords.

I think they are JST SM series connectors.

It's a common connector on lighting drivers. Not sure what the magic keywords are.

I considered the bump technique, but most lockers are quite big arrays. It could still be viable though. The Amazon style lockers tend to be in very public indoor areas.

You could perhaps use the latch to hold a locking bar - the bar would hold the door itself but not offer much in the way of paw-holds to force it open.

Safe from magnets, but may be susceptible to a bump. https://www.youtube.com/watch?v=7dl-y6GsdzA

Hi Clive, do you have a link or type for the black connectors used on these locks please?

That was my first idea, but these are pretty cool too. Just found a similar one that says "The shackle of this lock has no obvious permanent deformation under the pulling force of 150Kg;". I would think that is plenty strong enough!

They are designed to prevent people breaking into lockers easily, so I'd expect them to be pretty good. Especially the bigger one. Another option might be the magnetic door locks that just use a large electromagnet to hold doors closed. It could be wired to a timeswitch so that the door was unlocked on trash collections days.

Big Clive

Any idea how much force the latch could withstand? I know it sounds crazy, but I am looking for something bear-proof. Where I live we have black bears and I'm planning on building a housing to protect my trash cans from them. These look like they might work for that use case.
