I always say that if you cant pick it, and nde is necessary, you have to impression a key, now I know that you picked one, but do you think the mechanism could stand the forces of impressioning, considering that its on the kw1 blank which is readily available for impressioning. Just speculation on my part.

The lock can withstand the forces. As a test I took 5 new blanks and tried to force the cylinder to turn but in the end broke all 5 blanks. There was a slight bit of damage in that the wafers were distorted but the lock still functioned and resisted the test. Overall the lock is a good idea but poorly executed in the final product once you look at it closely.

Zeke79 sir,
I heard about this bumping and have seen some videos, from some of your comments you said these locks are bump proof. Would you recommend me buying some for my house or should I try picking them first? What other flaws do you think they might have? You also said key control was one of the weakness, how big of an issue is that? If you weight the benefits of the lock, does it out weight the bad or the other way around? I can't afford to buy a Medeco that's for sure. Are there other bump proof locks available that are within reason for cost?

I would not put them on my home no. As far as how big of an issue is key control? To answer your question, how hard to you want it to be for me to make a copy of your key if I a. see a picture of it b. have it in my posession for a few minutes c. impression it, etc.

that said you have have pretty expensive locks on your house. I know a lot of people disagree with me on this but i think as long as you have a better lock that the guy next door then its good enough. theres no point having a $300 lock on a door by a single pane of glass. locks enough are not enough for security.
remember most break ins will not be a thief picking a lock, bumping is on the rise but ide say impressioning is pretty rare (IMHO)
Thats just my 2cents though

if key control is the only issue, then it should still be better than other residential locks. I will get the benefits of bump and pick resistance. impressioning takes some skill and knowledge for some people, but bumping is not. Sure the KW1 keyway allows for regular picks to be use, but it is still resistant to picking than other pin and tumbler locks. Currently I have the Schlage B360 deadbolts on my door, but it is still a pin and tumbler. I can still pick them within 5 minutes even with the spool shape top pins. you said it took you 20 minutes for your first try for the new weiser lock, don't you consider that better than the Schlage then?

There are flaws other than the mechanical design of the locking mechanism itself that make the lock bad. Picking resistance is only part of the security matrix that makes a good lock.

I don't understand. I thought pick resistance is everything.....until bumping became an issue. Doesn't a side bar mechanism as you guys mentioned gives better resistance to picking than a pin and tumbler? what flaw are you refering to?

Brute force resistence is the most important if it has anything worthy of the name lock. Speaking of which, is that the flaw? That plug and shell looks like a cork to me.

I read somewhere that lockpicking is only involved 2% of the time out of all break-in crimes.
If a lock is a puzzle, then its key is the complete picture

Something like 48% is forced entry and the rest (sadly enough) happens because people just don't lock their doors and windows.
