What are the reasons why the BMW key is frequently undetectable
1 Answers
Reasons why the BMW key is frequently undetectable are as follows: Insufficient key battery: Low battery level in the key can cause detection failure. First prepare appropriate tools for opening the key, requiring small screwdrivers and new replacement batteries. Be sure to select the correct battery model. Vehicle cannot detect key signal: There may be signal interference sources at your location. Even after entering, the key remains undetectable. The temporary solution is to directly press the key against the start button. If there is a mechanical key, first lock the vehicle with it, then contact the 4S dealership or press the SOS button on the rearview mirror.
