Huangniu Brand Motorcycle Lock

[mechanical_nightmare]

Hello,

This is a motorcycle lock owned by a friend of mine. The keys for it are lost so he asked me if I could pick it, and I did fairly quickly. It has 5 pin stacks and no security pins. What is strange about it is that it has a E-shaped, dimple-like keyway.

Here is the lock in the locked position:

And in the picked/unlocked position:

Does this type of keyway have an official code or name? Also, is it possible for a locksmith to impression the lock? My friend would like to use it.

I am not sure about those questions; impressioning it, or not, but here is a link to another thread that talks more about those type of locks.

Also, those Chinese locks are usually pretty cheap. You, or he, may be better off just buying a new one. I have seen those for around 15 bucks on eBay.

Thanks for the link, so it is called a half-moon keyway and is a dimple lock after all. I agree that a new lock is a better choice, this one's pick resistance is just too low.

what kind of pick you use? i have same type padlock named SD SOLXD lock, but i failed to pick by half diamond or hook.
i found someone use flag pick at youtube, but i don't have one.

scissor tension was fit well for this lock.

I picked my lock with a homemade tensioner I made out of a paper clip type of thing and a Peterson DCAP hook. That was before I got some dimple lock picks. The flag picks definitely work better, but I have used other picks with success. Some have been able to pick them with a bogota. I think the issue is to have something thin enough to actually move around in there without getting hung up on warding. And to correct what I said about a 15 dollar lock of the same type; they may be a bit more expensive than that, but I think it would be easier (and cheaper) than trying to find someone who could fabricate or impression a key for it. I am not sure if you can even get blanks for those type of locks. I also am not sure if they are technically called a "half-moon" keyway. I would imagine they have another name and that was just a way of describing it to others. I don't have a whole lot of knowledge on those types of locks, perhaps someone knows the real name for the keyway?

I picked this lock using a hook short enough to maneuver through the warding. It is a home-made hacksaw blade pick, here is a picture back when I first made it (disregard the cheapo kwikset):

I also used the same tension tool that is in the picture, made from a windshield wiper insert. It was kind of awkward placing it into the side of the keyway and pushing against it by levering the tool between my thumb and index fingers, but it did the trick. I suppose a double-pronged tensioner could work better but I don't have one. As phrygianradar said, any pick that can move through the warding comfortably should do it.
