How to fasten a keychain

The general steps for fastening a keychain are as follows:

Check the keychain structure: Identify the type of clasp; common types include spring clasps, lobster clasps, and screw clasps.

Open the clasp: For spring clasps, press the spring part of the clasp with your finger to open it; for lobster clasps, flick the switch part of the clasp.

Hang the key or item: Align the loop of the key or other item with the opening of the clasp and gently push it in.

Close the clasp: Release the pressing or flicking part to ensure the clasp is fully closed and prevent it from falling off.

Precautions:

Avoid using excessive force during operation to avoid damaging the clasp.

Regularly check the closure of the clasp to ensure safety.

For keychains made of special materials (such as metal), take precautions against rust.
