Wipe Data From Your Car Before Selling It

Reset the Garage Door Opener
If you use a universal application, such as HomeLink, for example, you don’t want it to be sharing codes that grant access to your home. To erase them, press and hold the two outer HomeLink control buttons until the red light flashes.

Reset Telematics Services
Blue Link, FordPass, and OnStar can send data from a car to the cloud even if you don’t have a current subscription, Yu says. Look for an SOS or call button on the rearview mirror or overhead console. Press it and you'll be connected to a live operator, who can help you change the account owner information.

Log Out of Cloud Accounts
Exclusive to certain automakers, they store driver data, including preset radio stations, favorite temperature settings, navigation destinations, and driving history.

Remove Tracking Devices
Auto dealers, banks, and insurance companies may attach such devices to vehicles when setting up financing and coverage deals. If buyers don’t read the fine print, they might not realize they’re there. Once the car is paid off, check with your lender or dealer about disabling them.
