Richelock IU52 Double-Sided Keypad Lock – All-Weather Keyless Entry for Doors & Gates

Overview of the Richelock IU52

The Richelock IU52 pairs robust hardware with thoughtful design to deliver dual-sided access on a single device. Its identical backlit keypads on each knob support code-based entry from either side, while mechanical keys remain an option. This setup is ideal for entries you want accessible from both sides without compromising security or convenience.

Designed for real-world use, the IU52 keeps your entry points protected in a variety of environments. The keypad supports custom codes on each side, up to 50 unique 1- to 15-digit entries per side, and includes peep-proof security to help deter unauthorized observation. A convenient code-synchronization feature mirrors codes across both sides with a single programming action, making it well-suited for gates or dual-entry doors where synchronized access matters.

Key Capabilities That Matter in Everyday Life

• 🔐 Dual-Sided Smart Entry: identical, backlit keypads on both knobs allow secure entry from either side using a code or the mechanical key.
• 🗝️ Custom Codes & Peep-Proof Security: store up to 50 unique codes per side; protective design helps minimize shoulder surfing; sync codes across sides for seamless access.

• ⚙️ Auto-Lock, Manual & Silent Modes: default lock occurs after a short interval (adjustable 2 seconds to 12 hours); switch to manual for full control, enable guest mode for keyless guests, or silent mode for discreet operation.
• ❄️🔥 All-Weather Durability: waterproof construction handles outdoor exposure and extreme temperatures from -22°F to 176°F, keeping function in diverse climates.

Power and reliability are built in. The lock runs on two AA batteries with a lifespan measured in years and includes low-battery alerts. When needed, emergency power is available via Type-C ports beneath each handle, providing peace of mind for busy outdoor gates, fences, or pool entries.

Installation, Maintenance, and Support

Installing the IU52 is straightforward on standard US doors with backsets of 2-3/8" or 2-3/4". A Phillips screwdriver is all you need for a quick fit, and you’ll be up and running in minutes. The lock is backed by a 1-year warranty and 24/7 support, making it a practical choice for fencing, pool gates, and high-traffic entryways.
