Twist sensor counter-clockwise to remove from the base, then remove the batteries.  Leave the batteries out of the sensor for a minimum of 30 seconds before installing 3 fresh AAA alkaline batteries.
Twist sensor clockwise to close, ensuring the notch/line on the base and the notch/line on the sensor are aligned to avoid a tamper (you should hear it click/snap shut)
