Not necessary. It was a very helpful post.

I already have three U-locks (three bikes between me and the missus, all tucked away in a very safe underground garage) and two cables. I'll definitely be looking up locksmiths in my area to pick up that padlock very soon.

Yep.
Unfortunately, krypto locks are not rekeyable, and we cannot make keys for them.
I would highly recommend you replace that key before it breaks off, and renders you screwed.

Call kryptonite to get replacement keys.

Not really.
Two different sizes would be better though. If you can, use a short one so it is harder to get a prying tool/device in there.

Make sure you buy one with a quality key system. If you order from certain online stores, you can have multiple kryptos keyed alike (one key works both, or three, etc....)

Kryptonite locks are currently using a 'rotating disk tumbler' cylinder.
Very hard to pick (like thieves pick though), and there is no spring tension on the tumblers, so they tend to last a long time.

The best KEY SYSTEM on bike locks that I have seen is the 'MEDECO' padlocks that I mentioned before. These are miles ahead of anything else as far as key control and protection of the cylinder itself.

I do not work for medeco. I am not shilling. I don't really care what kind of lock you use. I am only recommending what I have seen and consider to be the toughest, most reliable PADLOCK.

The toughest, most reliable U lock would be the kryptonite brand.

It would be AWESOME if krypto and multi lock would get together and put the restricted medeco key into a heavy duty krypto U lock........

Schoolyard bullies typically do not recognize themselves as schoolyard bullies.

The first step in this long journey begins with areacode312 looking in the mirror.

I called a local reputable locksmith about the lock recommended in the original post, the Mul-T-Lock KW-E14H-1, and this lock costs $160 retail.

Ouch!

My local locksmith also recommended the same cable as did the original post, saying that this particular braided cable "squishes" under bolt cutters rather than cutting.

In fact, my local locksmith thinks the cable performs better than the chain.

I wrote the above conversationally, and not to take away from the original post.

Anyway, how does the round Kryptonite lock that came with my chain compare to the super lock in the original post?

I can see right way that the keyhole on my Kryptonite looks very vulnerable, but the shackle looks very well protected.

A very valuable original post.

Thanks.

Reminds me of the Sheldon technique.

Less than a month on board and you're coming into trash useful posts/threads.

Just settle down over there.

I use a 10 pound chain and a padlock (not the nice padlock from the OP though).

i feel fortunate that i work in a very well protected area, i can see my bike from my office window, and the complex i work in has a security force constantly driving the grounds.

i use a cheapy u-lock which i just leave attached to the bike rack on the days i bike commute to work.

thanks to the OP for this post though, good insite.

also, it is interesting to hear that theives break locks, never pick them, i wouldnt have known that.

right but isnt it true that locks are almost never picked, they are broken. the fancy locksmith key is not really worth it.

You are correct. Most locks are broken by thieves, not picked open.
However, occasionally, I have seen locks defeated by thieves drilling the plug of the cylinder out. This is virtually impossible with the padlock I have listed.

This lock is not for everyone. It is for those that can afford it, and see the value in buying the best. Even a grinder will take some time to cut through first, the hardened shackle guard, then the shackle. It is also about key control. NO ONE will be able to get your keys.

Use common sense. Use the lock that suits your needs best.

I appreciate the info here. What I can't get over is the cable suggestion. I mean, it seems to me that closing the cable loops with a $160 padlock is expensive decoration. The thief will not spend time on the lock if it's closed by a cable. They're going to cut the cable.

^Actually, when they see a U lock around the frame and a cable going through the wheels AND frame, they will probably just move on....

**I will say it again: YOU DON'T NEED THE BAD*** PADLOCK**
It just helps. If you can afford it.

you have seen this on a bike lock? this seems to be the sort of thing to do to a lock that is stable, like on a door, not a padlock hanging and swinging around on a chain. who holds the padlock steady while you drive a drill or whatever into the cylinder? wouldnt thieves with these tools just cut the lock?

no one can get my kryptonite keys either.

A) It is entirely possible to hold a U lock or padlock steady enough to drill out the cylinder with a cordless drill. I am not saying that this is common, but I have done it many times. (Customer lost keys and needs their lock removed).

B) Not true. There are a finite number of codes. If I had the proper machine (my lock shop just happens to not have the ability to generate disk tumbler, {or 'tibbe', in england} keys), I could make keys for your lock.

I am not trying to be combatative, rather, simply give you all some info....

hey crawdaddio... how do you feel about solid steel chains? i went to home depot and had 3 lengths of like 4 ft. each cut... then i got some allweather masterlocks and just leave the chains in various spots like school and work for when i need em...

not a bad idea eh?

I don't get it, I asked some questions. Period. Prove me wrong. EXACTLY, lol.
Point is, I said nothing that warrants personal insults, of course I'm fine with that, there are way too many people out there that have wayyy too thin skin.
Thanks for the attention, haha.

are you some kind of dick?

Well, solid steel chains can be snapped pretty easily with a pair of bolt cutters. Unless, you get hardened, or boron alloy steel.

It all depends on your risk of theft......

gotcha.. yeah the risk is definitely up there..
i always rock a mini-u for the front wheel to the frame as well.. those are necessary

I always run two U Locks. One New York Fahgettaboudit large lock, for the frame and rear tire. And a New York Fahgettaboudit mini disc lock for the 4' cable lock to thread thru the front wheel, and the rear again. Better safe than sorry!!

See my point. Talk about unwarranted. Whatever makes you feel better tough guy.

The issue is with your attitude. No one here insulted. You've done a fine job of that.

If you have something to contribute, please do. Otherwise... leave.

have you ever heard or seen an example of this happening to a Ulock resulting in a stolen bike? also it seems like your job would have been easier with an angle grinder.

wouldnt you need to have my key to make a duplicate? and in that case why would you bother making another? in fact if you wanted you could just call kryptonite with the number on the key and get a duplicate.

and yunno how many thieves have the proper machine? none. and yunno how many of those that do would rather just cut your lock in two? all of them.

my guess is that in the history of krypto keys (since they switched from the bic pen solvable kind) that not one bike has been stolen by a dude who made a new key. the guy who wants your bike would just cut the damn thing.

Funny that you're flat out wrong on every point, lol.
How about checking YOUR attitude, otherwise, leave.
