Plastic Key. Defeat Magnets.

[thelockopener]

OK heres my sencond idea on this dying branch of the forum. Embed to strong magnets onto the outside of the lock. Come close with metal lockpicks and *phwoom!* off they go. OPlastic key would avoid this feature.

So wait, you've devised an imagimary challenge to overcome, then a solution?

Way to go.

How big a magnet are you talking, a little one that fits in the lock that would have no effect, or a huge electromagnet hiding on the other side of the door so when someone comes to your door they get stuck on your door by their belt buckle , also most keys are made of brass, why would you want a plastic key thats going to break easy??

[zeke79]

I think you can skip the plastic keys unless you are putting in brass magnets too .

How about plastic magnets and a brass key? never mind stupid idea.........

[torbjorn]

plastic key, plastic picks.


it's all the same.

Ok, how about this then.....


Brass everything as normal, little disc magnet set in the top of each top pin, another oposing magnet set in the stack cap.... no need for springs! Slight posibility it would be unbumpable then.

As the key went in the shallowest cut would lift the pins to that level as it passed under them. A bit of dirt and they wouldn't fall back down very well without springs to help.

Plus Euro with the pins on the bottom wouldn't work at all without springs.

without springs.

But Snowy suggested little magnets as replacements for springs.
Cute

I re-read Snowy's post and it makes perfect sense to me now.

Duh.

I was thinking something completely different. Or maybe not thinking.

oh, sorry, it seems to have been some error in my posting.

I just wanted to ask why you think it will make the lock unbumpable ?
I think tat the newton principle is still active in this case, don't you ?

I may be wrong, of course, but really, I think it is still bumpable.

The reason I think it might possibly be unbumpable (or at least very hard to bump) is the cusioning effect of the increased oposing magnetic the further the pin travels up.

I mean I don't know? It was just a hair brained idea. Definitely worth a go though isn't it?

I've ordered some rare earth magnets. 2mm wide by 1mm deep. I'll stack them two high at each end to see if they can replace springs.
