Are you 100% sure our black key fob shell that use 2 batteries will work with only 1 battery?Β 

Keyecu say NO that this chrome key shell is NOT an upgrade but a replacement shell for an existing chrome key shell (very misleading information many has MB drivers has damaged their key circuitboard ending up with no working key

Can anyone confirm please?
