Preventing Lockpicking? Answered

(Please forgive me if I'm in the wrong category.. Fairly new on the forums) Hi, I'm quite a lockpicker in my life time but word spreads through out my "Friend Network" And most of them attempted on my door. I never do it to anyone without a damn good reason, but they do it for fun and pleasure.. So i always wondered cause i have a Keypad lock with a key hole. How do prevent them from picking my door to my valuable stuff while I can still use my key? Please help me out! (And i know ill get some replies saying to jam the key hole and use the number pad to open the door, what happens when the batteries dye out? I'll be stuck outside my room!)


. If you can open it with a key, someone can open it with a pick. Ie, there ain't no such thing as a pick-proof key lock.

How about one that requires a key shaped like L-channel? By having tumbler pins going multiple directions, it would be a pain in the butt to pick. Anyone who wants in enough to get past that lock would break a window, anyway.

some time ago i had a lock with a keyhole shaped like a +
it hat 4 different sets of 7 or 8 pins
i wonder how someone would attempt to pick that kind of lock

True there is no pick proof key lock, but there is some hard to pick locks out there Scorpion, Best, Medco and Schlage, all make very ignorant to pick locks with two sets of typically seven or eight pins, and the keys have groves cut down the sides for the second set of pins... (( Not cheap either most are well over $100 )) While I won't argue the fact they can't be picked, I can say this... It is easier to just go through the wall, or knock down the door..... (( opening most doors with a chainsaw only takes a minute or a few seconds with a sledge hammer )) Some thing the little boys looking at my daughter had better keep in mind )) <> And with security you don't need to make you place harder then Fort Knox to get into, just harder then the person living next to you....

well a safe lock, (those round locks that require a round key) sounds splendid but i dont think they make those for doors... I've been looking.

 Why won't you just get a combination lock with LOTS of numbers on it? If not then multiple combination locks with different codes on each one. Why waste on keypads and RFID's?

 Better yet, a hidden keyhole! When you come up to the door you'll see a keypad. It does function only as a deterrent. You just keep punching numbers in and hit enter it would keep beeping and beeping, but underneath the keypad is a normal lock. If you unlock it, it'll be still locked, because there's another lock which is camouflaged somewhere around the door!  

You could open the lock up and change the power supply to a 9V battery and have the connectors on the outside of the lock so you carry a battery around or just hide it near your door and then clip it in and use the door.

then wont the intruders find a 9V battery and use that instead? it will make it easier for them to break in

May I suggest a couple of good combo padlocks, the kind without a key override? If what they're hooked into is sturdy enough and properly attached to the door, your friends are going to have a long job ahead of them. You could also jam your key lock with a "dummy key" that has been hacksawed flush, but is made of steel. Jam the lock with it, then when you want in, magnet it out of there and use your key as normal. It would take a while for your friends to figure it out.

very interesting... thats a not bad idea, ill take a look into that.

call a locksmith and change the locks to something complex... i guess.... :)

they will still break into it unless i get a weird customized lock

you could always just put up a security camera and find out whos getting in. and then kill that person. and make an example of them for anyone else....

In a more mild suggestion, booby-trap your lock! Have a bucket of water ready to dump on them, or electrify your lock. There are lots of Instructables about making shockers, here's a good one.

electrify your lock ?? sure why not then when you kill them you can see what types of locks the government uses, and you'll have years to study them and try picking them .......

RUBBER GLOVES! ...I don't know... I don't think I am the one who needs to be creative; remember: Necessity is the mother of invention!

Well it is a common prank, and i probably wont do that to anyone yet. but as far as i see i dont think there is no solution to this other than actually jamming the lock and take a risk with the keypad that hopefully wont die out and leave me stranded outside my room

So the keypad runs on batteries... Hm... *trying to think of a way to take the batteries out when not in use, but that's impractical since that would compromise its security...* Or would it? Do you have a picture of this keypad? Would there be a way to take it apart without compromising its integrity?

Well i do forget to take batteries out when not in use (when in room) and i will pretty much forget to put it back in and have the door locked with the only way to get in is with the key, but for my "friends" who tries to break into my room... well it makes no different for them. Yea heres a picture of it.


Here's a thought to extend the life of the battery in the key-pad; add a reed-switch into the circuit, so that it only works at all if you are holding a magnet near a particular point on the door. That will extend the life of the battery, and even if your friends discover the code, they will not be able to use it without the secret of the magnet.

i like it, any idea on an instructable that may have this idea?

Not that I'm aware of for an actual lock, but there's a similar idea in the levitating pen ibles.

If I remember correctly, many magnetic sensors for the opening of a door are based on the magnet above it keeping the "switch" either open or closed (hopefully closed, that way if the wire it cut, the alarm goes off). This same switch could be employed in your aide it seems to me and would be readily available at any hardware / building supply store.

That's true, but they use rather large magnets, difficult to obscure their use from your lock-picking friends.

In Kipkay's Make project, he uses a tiny neodymium magnet, fastened to his ring, to trigger the reed switch.

Understood (yes, I remember that project well, and is on my "bucket list" LOL) . I wonder though if the "switch" portion could still be used / and therefor scrounged from "somewhere" ... :-)

Genius. That's it. Pure stinking genius.

You can replace the lock with a better one.
They make digital keypad locks that run on batteries alone, no key.
There is one that has a front leads that if the batteries die then you can still power the lock through the front leads.
icops lock (its in hangul )

this is kinda an english page (the manual is in engrish)

if you put in the wrong code 3 times, it beeps and wont do nothing until you leave it alone for a minute (even if you put in the right code). so your buddies cant just sit there and try every combo
Plus the batteries is supposed to last 1 year or so.
its a good lock

There are several alternatives to regular locks. The first is an RFID lock, which doesn't open unless the RFID chip is present. The second was already mentioned. A key code lock. Both of these are battery operated so if power is cut to your house the locks will still operate. They both also have battery backups such as a 9V battery, to use to type in the code with dead batteries. You can also just purchase a security system.

You could probably figure out a way to add a different lock, that requires knowledge to unlock it. It's a lot less corny than it seems, really. You'd have some sort of string to pull that unlocks it? Does that make sense? Just a bolt that can slide back and forth pretty freely, but unless you know that the string is there (in the corner?) you wouldn't be able to open it.

Ooh! Some kind of rubber cover that would make it look as if there is no key hole? Just throwing it out there...You would leave it in, people think it's only a keypad, with no hole. Unless all the doors are like that. Combination lock?
