15.0  Replacing the battery 
Generally speaking, the battery should only be replaced by a trained specialist. To 
open the housing you will need a Torx key of size TX6. Please proceed as follows:
1.  Fully unscrew the two screws from the base of the housing.  
2.  Remove the front of the housing. 
3.  Remove the battery from the holder.  
4.  Insert the new battery, making sure that the positive terminal is to the right; refer 
to markings on circuit board. (Please note: polarity MUST be correct!). 
5.  Reassemble the housing. 
6.  Screw the two screws back into the base of the housing. 
After the battery has been changed, all functions will be available again. 
When replacing the battery it is essential to ensure that no water can penetrate into 
the housing and no electronic parts come into contact with water. 
When replacing the battery, and immediately after inserting the battery, be careful not 
to touch the sensor or finger guide. This could lead to a loss of locking system data.
