The "cam" part is that flat metal tailpiece attached to the back of the cylinder. When you rotate the essential, the cam revolves with it. Depending on how it's set up, that cam possibly slides behind a frame to lock the door or rotates into the slot. It's the mechanical process that doesn't require electric batteries, Wi-Fi, or something fancy. It simply works, provided a person have the correct part of cut metallic you are holding.
A person might run into "wafer" cam locks too, which look similar from the outdoors but are generally a bit cheaper and easier in order to pick.

Exactly where You'll See Them Most

For many home or office uses, though, the standard version is enough. It's all about complementing the lock towards the risk. You wouldn't put a $100 high-security lock on the $20 plastic tool kit, just like you wouldn't utilize a simple cam lock in order to secure a jewellery store.

Instead, go with regard to a dry lubricant like graphite or a specialized Teflon-based spray. You just puff a small into the keyway, slide the essential in and out a few times, and it should feel like new. It's a tiny bit of maintenance that may create a cheap lock last for years.
