The Auto-Unlock feature allows your LINKA lock to automatically unlock when it recognizes you approaching.
a. Enable the Auto-Unlock feature by going to Settings 
in the bottom right corner of the app > Slide the Auto-Unlock toggle to ON
b. Once you leave the lock’s bluetooth range (~50m), the app will automatically disconnect from the lock, but in order to prevent accidental auto-unlocking, LINKA’s Auto-Unlock feature will not engage until you leave the safe zone of 200m and re-enter.
c. Once you leave the lock’s safe zone of 200m, you will receive a message that Auto-Unlock is engaged.
d. Your LINKA lock will automatically unlock again when you return to within a 3-5m (10-15 ft) radius of your bike.
NOTE: For the best experience with Auto-Unlocking, have your LINKA app running in the background before you begin walking to your bike, or simply leave your LINKA app running in the background so that it is always ready to automatically reconnect to the lock.
⇨ TIP: Auto-unlocking requires your lock to be active and awake, increasing battery usage drastically. If you wish to save battery, disable Auto-Unlocking.
