HFY408G Cloning Duplicator Key Fob Key benefits Simple onestep cloning: HFY408G's Learning Code technology makes it easy to copy an existing 433MHz gate or garage door remote so you can stop worrying about lost or inaccessible remotes. Secure access: Supports rolling code security to help prevent replay attacks and keep gate and garage door access more secure than fixedcode copies. Manage multiple remotes: Duplicate and carry additional fobs so family members, roommates, or staff each have reliable entry without reprogramming the original system. Reliable remote control: Designed for dependable distance operation with 433MHz compatibility for most standard gate and garage door systems that use this frequency. What it does Clones and duplicates 433MHz gate and garage door remote signals using HFY408G Learning Code functionality. Maintains rolling code security where applicable, preserving the security features of the original remote. Allows you to add extra remotes quickly, reducing downtime and the need for costly replacement remotes. Compatibility and performance Frequency: 433MHz — compatible with gate and garage door systems and remotes using 433MHz signals. Security: Supports rolling code systems when the original remote uses rolling code technology. Function: Designed specifically for cloning and duplicating gate and garage door remotes using HFY408G learning procedures. How it solves common problems Lost or damaged remote: Create a replacement without contacting the original manufacturer or replacing the whole system. Multiple users: Provide remotes to household members, caretakers, or staff without sharing a single device. Backup and convenience: Keep a spare fob in a vehicle or safe location to prevent being locked out. Practical use scenarios 1.
