Mercedes-Benz CLK320 key fob not opening driver's door on Mercedes-Benz CLK320

Some Mercedes-Benz CLK320 owners report experiencing issues with their key fob not opening the driver's door, which may require the fob to be pointed very close to the door for proper functionality. Others have noted that the problem could stem from a faulty switch within the key itself, particularly if the lock does not activate when aimed at the door. Additionally, some owners find that although the key fob's LED flashes when buttons are pressed, the door remains locked, indicating a potential synchronization issue that may arise after a battery change. Furthermore, if the key fob light does not illuminate even with new batteries, it could signal a more serious problem with the fob itself. In such cases, seeking assistance from a professional or dealership is recommended for further diagnosis and resolution.
