Coded lock

Start by considering where you will use it and what you need to protect. For travel and luggage, the 3 digits coded lock (like the pink metal model) offers compact protection, while the heavy‑duty 4‑digit option with a spring cable provides flexibility to loop through zippers, handles, or storage cages. For home use, a dedicated key storage solution with a 4‑digit code (aluminium alloy body) keeps keys secure and accessible only to trusted people. Each choice emphasizes core security and practical use alongside your everyday items.

Durability comes from a solid body and a coating that resists wear. You’ll find a metal body in the 3‑digit pink lock, while the 4‑digit model uses a chrome copper finish that stands up to moisture. The Key Safe Box uses aluminium alloy for light weight yet sturdy construction. Finishes matter because they can resist rust and corrosion in damp environments, and they also help you pick a color that makes the lock easy to identify among your belongings.

For travel, choose a lock that can secure multiple points on luggage or bags, such as the 4‑digit model with a spring cable, which is designed to thread through zippers and loops. For home storage, a dedicated Key Safe Box with a 4‑digit code offers a fixed access point for keys and small valuables, keeping them organized and accessible only to designated people. Lighter, smaller options like the 3‑digit pink lock are ideal for light-duty protection on personal items.

The 4‑digit model explicitly features a resettable code, letting you choose and change your combination as needed. The 3‑digit lock relies on the three-digit sequence you set, while the 4‑digit key box uses its own numeric code. Always note your code in a secure place and test it before relying on the lock to secure valuables to prevent access issues.

Sizes vary by model to suit different items. A compact 3‑digit lock is light and easy to carry for small bags, while the Key Safe Box measures about 116 x 94 x 38 mm and weighs roughly 320 g, making it suitable for wall mounting or secure key storage. The 4‑digit lock with a spring cable adds reach to secure luggage, carts, or larger storage spaces. Ensure the lock’s dimensions and cable length fit your intended item or mounting point.

Color and finish help you identify and differentiate locks quickly without affecting security. A pink 3‑digit lock adds a personal touch on smaller belongings, while a black or metallic finish provides a neutral look for larger gear. The chrome copper finish on the heavy‑duty 4‑digit model also lends a distinctive, durable appearance. Choose a hue that helps you recognize the item at a glance and matches how you organize your security devices.
