padlock with code|TSA Approved Luggage Locks for Secure Travel & Gym Use

Padlock with code is a portable, keyless security device that uses a numeric combination (mechanical dial or digital keypad) to secure items like lockers, backpacks, storage boxes, garden sheds, or small gates—offering convenience and flexibility for everyday use. Produced by Shanghai Kuntu Industrial Co., Ltd.—a BSCI-certified manufacturer with over 20 years of experience in designing consumer and light-commercial security solutions—this padlock balances affordability, ease of use, and reliable performance, making it suitable for global users including students, homeowners, small business owners, and travelers who want to avoid the hassle of managing physical keys. Unlike traditional keyed padlocks, Kuntu’s code-based models let users set, reset, and share combinations easily, adapting to changing needs. Practical scenarios demonstrate its versatility in daily life. For a high school student in Paris, France, Kuntu’s padlock with code secures their school locker, which holds textbooks, a laptop, and personal items. The student uses the 3-digit mechanical combination version—setting the code to their birthdate—so it’s easy to remember but hard for peers to guess. The padlock’s compact size (5cm×3cm×2cm) fits the locker’s small hasp, and the zinc alloy body resists scratches from backpack zippers. After a school year of daily use, the combination dial still turns smoothly, and the shackle (5mm steel) hasn’t bent despite accidental drops. A homeowner in Cape Town, South Africa, uses the padlock to secure a small garden shed storing gardening tools and pool accessories. The digital keypad version (with a backlit display) is perfect for evening use when accessing pool equipment, and the combination can be reset quickly if the homeowner shares access with a gardener. The padlock’s IP54 water resistance rating protects it from occasional rain, and the battery (one CR2032) lasts up to 12 months. For a small café owner in Tokyo, Japan, the padlock secures a storage cabinet holding coffee beans and disposable cups. The owner sets a 4-digit code for staff, and the mechanical version requires no batteries—ideal for a busy café where power access near the cabinet is limited. The padlock’s low-profile design doesn’t take up space in the cabinet, and the shackle’s 25mm opening fits the cabinet’s hasp perfectly. Kuntu’s padlock with code is designed for user-friendliness and durability. Two main types are available: mechanical (with a rotating dial) and digital (with a keypad). The mechanical version uses a brass combination mechanism that requires no power, making it ideal for long-term storage or areas without battery access, and it can be reset by rotating the dial to a specific position—no tools needed. The digital version features a backlit keypad (for low-light use), a low-battery indicator (via LED), and a lockout function that disables the keypad for 3 minutes after 3 failed attempts. The lock body is made of high-grade zinc alloy, treated with a nickel-plated or powder-coated finish that resists scratches and mild corrosion, while the shackle is 5mm-6mm hardened steel—thick enough to resist bending or cutting with basic tools. Combination lengths range from 3 to 4 digits, with 1,000-10,000 unique combinations depending on the model. All padlocks meet EN 1300 standards for general lock durability, ensuring they withstand daily use for 5+ years. For clients with custom needs—such as branded padlocks (with logos for schools or businesses), or color options (black, silver, blue) to match personal or corporate aesthetics—Kuntu’s R&D team can provide tailored solutions. The foreign trade team also assists with regional compliance, such as ensuring materials meet EU RoHS standards or U.S. CPSIA requirements for consumer products.
