In forcible entry, there are a number of myths surrounding the through-the-lock method, specifically in regard to commercial-style doors, sometimes called aluminum-style doors (Photo 1).
最初是在1960年代开发的锁定强制入境技术，以回应美国人变得更加安全意识。人们在门上安装了更多优质的锁，使传统的强行进入技术更难执行。消防人员发现，有时会更快，劳动力较少，而不是从字面上“通过锁”而不是传统上强迫门。
Through-the-lock basically duplicates the key action within the lock. The two-step process involves removing the lock cylinder and then actuatinng the lock mechanism. The firefighter can remove the cylinder by spinning it off using locking or water pump pliers, a K tool or other lock-pulling tool, or the adz end of halligan.
可以通过钥匙道的位置将弯曲锁定为基准。从时钟方面考虑键道；通常，锁从5点钟到7点的位置或7点钟到5点钟的位置（照片2）。
Once the cylinder is removed, you now must actuate the lock using a key tool or Kerry tool (Photo 3).

Take the Glass?
With all forcible entry options on the table, time and time again, we hear people say, “Well, I would just take the glass.” Although taking the glass may very well get you into the structure, in doing so, you have violated a very crucial rule of forcible entry–maintaining the integrity of the door. Numerous articles stress the importance of controlling the door with regard to improper ventilation and so forth.
So you have decided to take the glass. Let’s say we were lucky enough that the glass was tempered or plate glass, now we have a floor full of glass shards over which we are going to be pushing the hose and crawling on our hands and knees. In our districts, we are seeing a trend with using laminated glass and even lexan to improve security for the business (Photos 5 and 6).
Again, we hear the argument that it is cheaper to replace the glass than it is to have the locksmith replace the set screws in the cylinder. I challenge you is to go out and talk to your local locksmiths, and see what they have to say on the price differences.
Look at Photos 7-10 below. Once you have taken the glass (if you are able) on these doors, now what? Remember, you are at the scene of a fire. The glass is now gone, so the smoke and fire are now meeting you at the ventilation opening you just created. Would you grab the rotary saw and start sawing the bars away? Sure, you could do that, but again this is more time-consuming than just going through the lock, and we all know that time is quickly running out on us at the scene of a fire. We need to work smarter, not harder; we may now have to push the line in after forcing the door, conduct a search, and so forth.

以下视频展示了穿过锁和取玻璃之间的时间差异（将花费的时间与上面的锁定视频相比）。
有一百万种猫皮肤的方法，并且可能有少数情况下，唯一的选择是唯一的选择。整个锁定的技术正在成为一门失落的艺术，作为专业人士，我们必须寻求培训以改善自己并教育我们的消防员。
