How to factory reset my Garmin Fenix 3, Fenix 5 or Forerunner watch

If you are having issues with your Garmin watch that a normal reset cant handle or looking to sell your Garmin watch then you will need to perform a factory reset or also known as a Hard reset. Follow this article on how to perform a factory reset of your Garmin Fenix5, Fenix 3 or Forerunner watch.

So before I begin taking you through the process of performing a factory reset of your Garmin watch, let’s explain why you would perform a hard reset and the result you will get on your Garmin Fenix 5, Fenix 3 and Forerunner watch.

Performing a factory / hard reset on your Garmin Fenix 3, Fenix 5 or Forerunner watch – Why you would do this?How to hard reset a Fenix 5

You may want to perform a hard or factory reset of a Garmin watch to fix issues that cant be fixed that are not corrected with a soft reset. I would also advise doing a full factory reset when you are selling your Garmin watch to a friend or on eBay for example as leaving data on the device is not wise, given it could have GPS location data for instance that could be used to locate you.

The factory / master / hard reset method will clear any settings or data from the Garmin Fenix 5, Fenix 3 or Forerunner, such as;

  • VO2max and LTHR
  • Distance, elevation totals or any achievements.
  • Saved Bluetooth or ANT+ sensors such as HR, power meters or foot-pods and the associated calibration
  • Apps, widgets, watch faces or anything downloaded from Garmin IQ store.
  • Sports profiles or customisation you have done to the data screens or layout.
  • Any maps you have saved on the device.
  • Any of your saved workout data

Doing this factory reset returns your Garmin watch to the same state as when it was new from the factory.

Hey Jon,

as I’m stuck in a boot loop with my Fenix 5X+…

there is a mistake in the Hard-reset or Factory-reset Garmin watch – Option 3

It is the sentence “Press and hold the buttons labelled up and down once the Garmin logo appears”

Up and Down are not the buttons to push but the Start Button and the Back Button.

Cheers
Nemo

You forgot to change it, or is the up and down buttons the correct buttons to press?
