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 cost-effective compared to the green board. Functions identically to the green board with the only difference being the color. BE Smart Key Features: - Super stable frequency, switchable between 315MHz and 433MHz - Reusable design can be reset - Compatible with various MB key programmers including Autel IM608, CGDI MB, Key Tool Plus, Digimaster-III, CKM100, AK500, MBE MB-KEY OBD2, NEC-57 MB-PRO, and others - Works with MB smart key systems for lock, unlock, and trunk functions - High-quality construction with reliable performance Applicable Chip Models: 705 Moto (19972000), NEC (20012005), NEC (20062010), BGA (after 2011) Frequency Reset Methods: 1) Use of PCB SMD resistor: Install a 1K SMD resistor at the designated location to set frequency to 315MHz; removing the resistor changes it to 433.92MHz 2) Change frequency between 315MHz and 433MHz using MB Tool BE Key Pro Features: - Enhanced compatibility - New design for improved performance - High stability and reliability - Digital signature support - High quality at a competitive price - No points accumulation Improvements in BE Key Pro: 1. Fixed synchronization issue between W164/W639 EIS data and key 2. Resolved ignition activation failure after multiple attempts 3. Fixed trunk remote open function 4. Improved RF signal transmission now sends signal twice (on press and release) instead of once 5. Updated rolling algorithm to correct previous errors 6. Added pre-roll algorithm allowing HASH value to roll ahead 7. Integrated automotive-grade quartz crystal for enhanced infrared communication stability 8. Strengthened infrared signal upon button press 9. Supports frequency reset between 315MHz and 433.92MHz via MB Tool or PCB SMD resistor Note: When using MB Tool, it takes priority over the SMD resistor method. If frequency was previously set using MB Tool, the SMD resistor will not function until the setting is erased via MB Tool. Package Includes: 1 x BE Key Pro Yellow Version 1 x Smart Key Shell
