Removal
Warning: When removing batteries, check if the polarity is indicated on the battery. If the polarity is not indicated, mark the battery position.
1. Insert a coin into the slot on the side of the handle (arrow 2 in the illustration).
2. Turn the coin and thus remove the upper part of the key handle.
Warning: Be careful not to let the button spring (arrow 1) pop out when removing the top part.
3. Replace the battery or lamp.
4. Press the key housing cover and lock it in place. Make sure that the button does not get pinched.
