Use a thin card or hairpin you have at hand, and apply the lever principle to pry open a small gap to thread the keys through. You can use a straw, as long as it can pass through the keyhole. Cut out a small section. If the straw doesn't have a bend, you don't need to cut it. Insert one end of the straw into the open end of the key ring—it will go in easily. Then thread the key through the straw.

I recently learned how to attach a keychain, and it's actually quite simple. First, take a keyring, usually a small metal loop with an opening at one end. Gently pry it open with your fingers or pliers to create a gap. Then, slide your car key through—note that the end of the key has a small hole; align it and slip it in. Next, attach the keychain you want to hang, which can be any small decoration, like an animal-shaped charm or a company logo, but make sure it's not too heavy. When attaching car keys, smart keys are particularly fragile—avoid hanging heavy items, as pressing the buttons too hard could damage them. Traditional mechanical keys are more durable. Finally, press the opening of the ring tightly and apply some force to ensure it doesn’t loosen, otherwise, it might fall off while driving over bumps. I once dropped my keys, and picking them up was a hassle, so I recommend checking the ring’s tightness regularly. Opt for lightweight plastic keychains for safety, and don’t hang too many—one or two is enough.

Having driven for over a decade, I often help friends attach keychains. Use your thumb to open the keyring's split ring, insert the key, then thread the keychain through. Regular car keys are fine, but for premium smart keys, weight control is crucial: exceeding 20 grams may damage internal chips, affecting remote start or unlock functions—opt for silicone or fabric keychains, avoiding metal ones. Installation involves three steps: open the ring, add key and keychain, then close the ring; ensure it's tightly secured—use pliers if loose. Remember, if your car key has a USB port, avoid blocking it with accessories to prevent charging issues. Pro tip: always work on a flat surface for safety to avoid cuts.

I usually just attach keychains directly, and it's a quick process. Open the gap on the keyring, gently pull it apart to create a small opening, slide the car key in, and then add a new charm, like those anime trinkets I collect. But for car keychains, size matters: overly bulky ones can get stuck in the steering wheel hole, causing distraction while driving. Light-up or sound-effect keychains are fun, but always check the battery compartment for leaks before attaching to avoid corrosion on the key. Avoid using excessive force during the process, as the ring can easily snap and fly off.

As a DIY enthusiast, I have experience installing keychains. Prepare small pliers for opening the rings, and choose standard ring diameters of 12-20mm to fit most car keys. After attaching the key, apply some grease to prevent rust, then thread the keychain through and close the ring securely; test by pulling a few times to ensure stability. Be cautious with car keys: avoid hanging multiple keychains on smart keys, as the weight can distort the chain and damage the internal structure of the ignition switch. Non-metal materials are recommended, with plastic or rubber being the best to minimize the risk of scratches. I often make my own keychains, but always assess the weight-bearing capacity before installation to prevent chain breakage and key loss. After completion, clean up any debris to keep the keys tidy.
