Just had my car in for its annual service and other minor problems to be addressed. Among them I stated that while key was with person in drivers seat and the car was in the unlocked status for doors the handles would randomly present themselves. Tesla noted it was possibly due to the weak key fob battery and/or my dashcam (blackvue 650). Has anyone had issues with key detection while using a dashcam or had similar issues caused by a dashcam? Concern: Customer states: All door handles present randomly when key is in the car. Corrections: Exterior Door Handles General Diagnosis Tested concern and was unable to duplicate at service. Reviewed logs and found error reading of key sense antenna. Performed antenna test and confirmed correct operation. Per toolbox article, Aftermarket brand equipped dashcam is known to cause issues with Model S key detection. Suspect weak key batteries and interference from dashcam are cause of handle behavior. Replaced both key batteries at this time. Recommend removal of Aftermarket dashcam to allow system to operate normally.
