BE Key Pro V3.2 Yellow Board 315MHz/433MHz for All MB Key Systems The yellow board does not include bonus points but is more affordable than the green board. Functions identically to the green board with the only difference being the color. BE Smart Key Features: - Super stable with changeable frequency: 315MHz / 433MHz - Reusable and can be reset - Programmable using various MB key programmers such as Autel IM608, CGDI, Key Tool Plus, Digimaster-III, CKM100, AK500, MBE MB-KEY OBD2, NEC-57 MB-PRO, and others - Compatible with MB smart key systems for lock, unlock, and trunk functions - High-quality construction with reliable performance Compatible Chip Models: 705 Moto (19972000), NEC (20012005), NEC (20062010), BGA (after 2011) Frequency Reset Methods: 1) Use PCB SMD resistor: Install a 1K SMD resistor at the marked position for 315MHz; remove it to switch to 433.92MHz 2) Change frequency between 315MHz and 433MHz using MB Tool BE Key Pro Advantages: - Increased compatibility - Improved design - High stability and reliability - Digital signature support - Cost-effective without point accumulation Improvements Included: 1. Fixed synchronization issue between W164/W639 EIS data and key 2. Resolved ignition failure after repeated attempts 3. Fixed trunk remote opening issue 4. Enhanced RF signal transmission: now sends signal twice (on press and release) instead of once 5. Updated rolling algorithm to correct BE key errors 6. Added pre-roll algorithm allowing HASH value to roll ahead 7. Integrated automotive-grade quartz crystal for improved infrared communication stability 8. Strengthened infrared signal upon button press 9. Supports frequency switching between 315MHz and 433.92MHz via MB Tool or PCB SMD resistor Note: When using MB Tool, it takes priority over the SMD resistor. If frequency was set via MB Tool, the SMD resistor method will not function until the MB Tool is used to erase the setting first. Package Includes: 1 x BE Key Pro Yellow Version 1 x Smart Key Shell
