译者按：忘带钥匙了想找撬锁匠，但看对方那獐头鼠目/道貌岸然样就担忧家里各种银行卡、电视的安全。用锤子爆门，万一热心的邻居因为害怕而不加确认直接119了……还不如自己先做几把钥匙防备吧……

How to make a useable copy of a key!
且看如何做一个钥匙实用拷贝吧！

You can use this to copy a cylinder lock key within minutes. Especially great if you have a key that says 'do not copy' on it. You will need:
用这个能在短短几分钟内做个开锁芯的钥匙，尤其是那种上头写着”谨防翻刻“字样的。（译者注：知法犯法，减压良药！）你需要：

Access to the key (for a few seconds)
A drinks can or other thin metal
Paper
Scissors
Glue
Printer
Ruler or other hard blunt edge
到手一把钥匙（只要几秒钟足矣）
饮料罐或其他薄金属片
纸张
剪刀
胶水
打印机
尺子或其他带硬、钝边缘的材料

I have copied a master key for an entire office block doing this and it worked fine.... I have also copied a Yale lock key for a lock which I have been having trouble picking.
我拷贝了整栋办公室大楼的主钥匙，拷贝件工作畅顺……我同时也复制了一把耶鲁锁钥匙，用来对付很难撬开的锁。

Step 1: Copy the key - quick!

一、复印钥匙——要快！

Get a copy of the key using either:
用下面的的工具可以拷贝钥匙：

Scanner - easiest
扫描仪——最简单了
Camera - you must have a scale present in the picture (ruler etc)
照相机——你必须有个在图片中显示参照比例的东西（例如尺子）
Photocopier
复印机
Impression in bluetak or clay, then scan it or photocopy it. I personally would try and highlight the impression with tipex or something first to ensure a good print.
感觉最好还是用蓝丁胶或粘土，然后拿去扫描或复印。我个人会尝试用涂改液或其他东西制作高反差效果，让打印效果好一点。

Print 2 copies of it in the correct scale so that you have two 1:1 copies of the key
用正确的比例打印两份拷贝，这样你就有了两把1:1的钥匙拷贝了。

Now roughly cut the copies out. Don't worry about cutting each tooth properly, just leave excess paper around it all.
现在粗略裁出来。先别忙于怎样剪出每个齿边，而是在外面留些余地出来。

Step 2: Thin Metal

二、薄金属

Take a drinks can/tin and cut a rectangle big enough to stick the key to, or any other thin metal. I have included picture of me copying the same key on a drinks can and a fish tin!
取来一个饮料罐/马口铁罐头，剪出一个足够大的长方形，能把钥匙贴在上面的，或者用其他薄金属片也可以。这里我附上将钥匙用饮料罐或鱼罐头拷贝钥匙的画面！

Stick 1 cutout key onto it.
将一枚剪出的钥匙粘在上面。

Step 3: Cut the copy

三、裁剪拷贝

Cut the new metal key copy out. You need to cut it leaving some excess metal around the teeth area, we will need the excess later!
剪下新的金属钥匙拷贝，在齿边还是需要留下些余地，之后有用！

See the second picture if you are unsure what I mean....
不明白我的意思的话看第二幅图……

Step 4: Make the groove

四、做刻槽

Take another key with a groove in it, it doesn't have to be the original, we are going to use the groove in it to create our groove in the copy.
拿出另一把带刻槽的钥匙，不需要是原本那条，我们用它做拷贝钥匙上的刻槽。

Now line the groove up with your printout and force a groove into your new copy using a ruler or something thin and blunt. Press the ruler down and whilst holding it down flatten the sides which will now be sticking up in a V shape. See the pictures for detail.
现在将刻槽摆在打印件上面，用力用尺子或一些又薄又钝的东西将刻槽刻在上面。按下尺子，同时用边按下去，贴合成V形。细节见图片。

Step 5: Make the final cuts

五、最终裁切

Now that you have the correct grooves, you can line up the key with the second printed copy, at this point you will need to cut the second printout exactly around the profile of the key (teeth included). Now it will become apparent why we left some extra on the teeth; the groove will have shortened the height of the key and so the teeth now need to be cut higher up on the metal.
现在有了合适的刻槽，就能将第二枚打印拷贝放进去了。这时你要将第二枚打印件沿着钥匙文档准确切割（要包括齿边）。显而易见，这就是为何当时我们预留了齿边的空间的原因；刻痕会减少钥匙本身的高度，然后现在就要在金属高一点的地方剪出齿边。

Cut the teeth with continual reference to the printout. This is the crucial part, it must be very accurate. Make sure the teeth are not slanting to one side, if this is the case then the thin metal may slide down the edge of the pins and not push them up. Use scissors with a good pointed cutting end and try to cut only using this end.... this allows you to get quite accurate cuts without manoeuvring the scissors around risking bending the teeth.
根据后续的参考指示切出齿边。这一步很关键，要非常准确。让齿边不是沿着一边歪斜的，要不然薄金属会滑开撞针边缘，而不是把它们顶起来。用尖头剪刀剪切，尝试只用尖端部分……这样会做出比较精确的切痕，而无需沿着边缘做修补，以免发生齿边弯曲的情况。

Step 6: Use the key!

六、使用钥匙！

Insert the key into your lock of choice, do this slowly, you may need to wiggle it very gently, but if your copy is good then it WILL go in fine. Now you must use a tension wrench or otherwise to turn the lock because the metal is not strong enough. You may need to gently move the key in and out of the lock by a few millimeters. Its amazing when you see it turn!
将钥匙插入锁里面，慢慢地，可能需要轻微扭动，如果复制钥匙做得好的话就很畅顺。现在要用到一把转矩扳手或其他东西去转锁，因为这块金属强度不足。（译者注：换而言之，用来堵钥匙会比牙签更加有效！）可能需要稍微在锁里面几毫米之间活动一下钥匙。看到它转动后，那个兴奋啊！

The tension wrench is simply an L shaped flat piece of strong metal which can be inserted into the keyway allowing me to turn it. You can construct this from a paperclip, or use a thin flat screwdriver.
转矩扳手，简单来说就是一个L形强度大的扁金属，能够插入钥匙扁孔中，并能转动的东西。你可以用回形针或其他扁嘴螺丝刀做一个来代替。

I have made four different keys using this method, and they all work!
我用这个方法做了四枚不同的钥匙，全部成功！

If you find your copy isn't quite working, compare it to the printout again. If this looks fine, then watch the way the key interacts with the pins as it enters the lock... if you find it moves to the side of them, then bend the teeth in a bit to compensate.
如果拷贝件不能正常使用，将其和打印模板比较一下。如果看起来相同，那就观察它插入锁之后和锁芯撞针之间的反应……如果发现它滑到边缘，那就稍微弯一下齿边来补偿一下空位吧。
