EoneBoss ED01 is a specialized key copying tool designed for 2018+ Jaguar Land Rover (JLR) vehicles and selected Toyota 4A smart key systems. It allows auto locksmiths to perform direct NXP chip cloning and generate replacement smart keys with full Ultra-Wideband (UWB) keyless entry functions without disassembling vehicle modules.

Key Product Features & Core Advantages
- No KVM Disassembly:Clones working keys directly on bench without removing or opening the KVM (RFA) module.
- No Module Replacement or Online Programming:Eliminates the need for dealer online coding or buying new unlocked RFA modules.
- Direct NXP Chip Cloning:Compatible with 29A4 and 29AF chip architectures.
- No Synchronization Issues:Prevents rolling code tracking, out-of-sync remotes, or code-de-synchronization errors.
- Key Position Allocation:Reads data from an existing working key and assigns the new key to a lost key’s position and ID, preventing duplicate ID conflicts.
- Remote Counter Adjustment:Allows direct modification of the remote counter to align key frequencies if remote functions fail after cloning (also supports OEM keys post-cloning).
- Magnetic Adapter Design:Ensures fast hardware connection and easy chip alignment during operations.
