Step 1. Pull out the key blade sliding the spring-loaded catch (1) to the side while pulling the key blade (2) out.

Step 2. Place the remote control with the keypad downward and remove the screw (3) using a small screwdriver.

Step 3. Remove the cover.
Step 4. Carefully note the position of the battery’s + and – poles on the inside of the cover.
Step 5. Prise out (4) and change the battery (Battery type CR 2032, 3 V). Avoid touching the battery and its terminals with your fingers.

Step 6. Refit the cover and screw.
Step 7. Press the key blade back into place.
