    ❗️Do not use a screwdriver.

  2. Insert the 9V battery into the adapter.

  3. Place the adapter against the cylinder. Make sure the pins on the cylinder align with the pins on the adapter. When you hear a buzzing sound, the cylinder is powered.


    💡 Please note that the pin layout differs between indoor and outdoor cylinders.

    💡 Indoor version: Use the pins closest to the center on the side with four pins.


    💡 Outdoor version: Use the pins on the side with two pins.

  4. Keep the adapter pressed against the cylinder. Open the Parakey app, press the three dots next to the lock's name, then press Replace batteries.

  5. Complete the first step: Unlock the locking pins.

    ❗️Keep the adapter pressed against the cylinder until the locking pins are unlocked.

  6. Continue following the instructions in the app to complete the battery replacement.

  7. Reattach the logo cover once the battery replacement is complete.
