Lock Bumping Solutions
lock bumping
It looks like there is a few solutions to this lock bumping craze. You can either buy yourself a new lock or buy a non lock device that basically stops the inside deadbolt handle from turning. It seems that no lock is fully bump proof but these locks below make it a lot harder for the average joe to bump the lock.

Deadbolt Knob Stopper:
Also a good thing to do to your current lock is spray some Lock Lubricant

Due to the nature of my front door, I had no choice but to install the lock upside down. It seems to me that this simple move makes the lock completely bump-proof because the lower pins will always be resting against the upper ones. You don’t have gravity working as your friend. Am I right? Can anyone test this? I haven’t tried to make a bump key.
Thanks!

You should add The Ultimate Lock to this list. Its one of the only locks that prevents lock bumping using a ’smart key’ type system. But not all Medeco locks are bump proof. Contact me if you have any questions

the best lunpickable and unbumpale lock is 1 with no outside key hole or access of any kind
i like the 2×4 brackets that are sole at any home improvement store
simple mount the brackets in to the frame or brick and put a 2×4 or a 1-1/2 square beam in place
i did that for my store well 3
i took out a few bricks then put a steel plate with machine screws sticking out then filled the area in with anchoring cement
with a very heavy steel door i had a few meth heads try from time to time if you ware to try to kick that door down you could start at 10:00 pm and quit at 9am and still fail in fact they did not even make a dent
i had to stay over night to keep my computers running i had a cyber cafe
sometime it was like a knock knock or once sounded like a car crash and a loud scream i found blood and bone fragmentts the next morning he must of had a compound fracture ouch
even a 200 lb heating and air guy who was a friend of failed to get my attention with a prank shoulder bash as we did not here him he thought it would be funny to spook me right after i put it up anything short of a bulldozer was not coming though as the wals l were 8 layers of brick
yes you can keep out the most determined burglar as a bull dozzer plowing though a 4 car grange or atl least half a carr ,s width would tip off the neighbors not to mention the 8 layers will take some time and the cops will be on the way with half the 16th Chicago police district
but at what cost i had $50 k in computers to protect and i had architecture on my side
but the brackets and a 2×4 or a steel bar is the best lock you can get if you are worried about the someone breaking in though a door while yor are in the house
if you do not believe me take a 2×4 8 in long and try to snap it or try geing a 1-1/2 in square beam with a wall thicknes of 1/4 in 4ft long and try to bend it
but remember theat if you studied physics and understand how this locking device works 95 of the force is applyed to a 8 inch peace by the lock side of the door in the form of shear force it is like a lever kinda
shear force is like what bolt cutter us to cut chain they apply many thousands of pounds per square inch but only cove 1- 64th of a inch so 100,000 pounds of psi is 1562.5 pounds of pressure with a coumpund lever a very big man can easely cut some very heavy chain
but the bolt cuter here has a blade 8 inches wide and the burglar can not change that now this works out fine as long as your other hard ware and wall hold up
but if installed with some for thought this system is at least 10 times stronger than ANY DEADBOLT but if you simply mount these brackets like you ware hanging a picture a 12 year old could kick it in
