Adding drill resistance to deadbolts

[Microwarrior]

I have been working on making a kwikset more pick resistant and I might use it on my door, but the pins and lock are made of soft metal. How could I increase my lock's drill resistance on the cheap?

This can work on almost any lock.

With a little crude machine work you can replace a few top and bottom pins with broken pieces of #31 diameter, high-speed steel drill bits. Break off a piece of drill bit and chuck it in your drill. Them turn it against a grinder wheel until beveled and smooth. Finish the rounded tip with very fine sand paper. Carefully shorten it from the flat top until you get the length you want. Break the sharp corners on top for smooth operation. Do the same with a few top pins, (flat on both ends or make spools.)

Put ball bearings in the bottom of the mounting screw holes. Find better screws and increase the diameter by one size unless already 1/4-20. You will have to rethread the holes.

Fill the hollow shell with Steel-stick mixed with hardened sheet metal screws.

Tie a couple of pit bulls to the door knob.

Connect to a 220 volt electric line.

Or, if you think this is too dangerous or will take too much time, buy a better deadbolt.

Thanks for the advice! Ill look into the pit bulls too.

Haha, I like it! Especially the very last piece of advice.

Great advise, Raymond.

However, pit bulls are illegal in some states now. In which case, just one of these should do the trick...



That's his happy face. You don't want to see his angry face.

The effect can be improved by laying out spread eagle a used priest's outfit, fit it with fake hands (one holding a container of holy water, the other holding a Bible, feet, head and bloody entrails, and a sign at the gate saying "Exorcism in progress. Please wait".

Na that's only 120 VAC over ground, connect the deadbolt to a neon sign transformer, that's about 7.5 Kv over ground, which is enough to deter picking or drilling, unless gloved-up and it also gives a totally new meaning to the term "dead bolt."

You have always heard how viscious those little dogs are. I will have you know that they can kill rots, shepards, dobermans, and even pits. They grab hold while they are being swallowd and the big dog chokes.

You can also attach a switch to the deadbolt that plays a tape saying: "Do you feel lucky, punk?"

lol yes... Then, the intruder who tries to pick the lock will be caught "red handed"

[globallockytoo]

adding to Raymonds original post....

You might consider removing the plug completely. Drill a fine hole directly in line with the shear line, say about 7/64". Make sure hole depth does not go through to first pin chamber. Insert hardened ball bearing into hole and use lead shot to fill around the ball bearing.

Do the same to the connecting screw holes on the external cylinder body.

Hardened ball bearings will distract a drill bit, making it very difficult to drill those positions.

Don't. Years ago a guy in Australia did this to stop strangers using an outside toilet. The first victim was his daughter and he faced a manslaughter charge.

Was that in home alone that he out like some kinda electric heater on the door know haha that was great always thought that might be a good idea, but you'd have to carry around oven mits with you everywhere which could lead to awkward questions lol. Then you could just tell everyone your were a hand model like Seinfeld hahaha

One year way back when I was in junior high school, we had a real dick for a shop class instructor, he was a coach but was transferred to shop class and he hated it and those in the class as well.

One fine day a few of us had enough of his nonsense and once he stepped out back to have a smoke, we decided to teach him one of the basics of metallurgy, that being hot metal, if not heated too hot, looks just like cold metal.

After he went out back, we rolled a oxy-acetylene torch over to the door and I warmed up that lever nice and hot, the door stop was kicked up and the door slammed shut.

Everything was quickly put up and we all went back to our assignments, then a minute or so later there was this blood curdling scream from the other side of the door, followed by a litany of four letter words, after which a couple of un-involved students (who weren't laughing their fannies off) opened the door and once the coach explained his immediate problem, a cold wet towel was applied to his hand and he trotted off to the nurses office cursing all the way.

There was big whoop-da-do the next day but no one was willing to rat anyone out and the coach was transferred back to the locker room and as a replacement we got an English teacher, who was more of a paper pusher than a B-buster.
