This tip will help you avoid ending a run early or pressing the lap button when you didn’t mean to. On most Garmin models, before you start the activity, press and hold down the top left hand button, which will then show you a screen of lots of different options. Scroll to the padlock icon, called Lock Keys and select it. You’ll be taken back to the Run screen and a padlock icon will show up for a couple of seconds in the middle of the screen. When you’re ready to start the run, press and hold any of the buttons and the padlock will unlock again. If you don’t have the padlock option on your watch, you can add it via the Controls menu on your watch. You can also set it up to happen automatically by selecting the Auto Lock feature in the System Settings Menu.
