Changing the Battery in an NXT/NXT Wireless Lockbox
Introduction
The NXT/NXT Wireless (blue) REALTOR® lockbox has an internal lithium battery. The batteries in
NXT/NXT Wireless lockboxes last up to 6 years, depending upon climate, storage and use.
Note
: Do not remove old batteries from a lockbox until you have a replacement in hand. Also, do
not carry unpackaged batteries in your pocket or purse as metal objects could cause a short
circuit and thereby cause bodily harm or property damage.
What you Will Need
To replace the battery in an NXT/NXT Wireless (blue) lockbox, you will need:
•
2 lithium type CR123A batteries. Contact your Association in regards to obtaining batteries
for your lockbox
•
A Phillips head screwdriver to remove the battery cover screws
The battery cover for an NXT or NXT Wireless
(blue) lockbox is easy to
identify because it may have a label with a picture of a crossed out key
affixed to it. This label can be found inside the key compartment, against the
back side of the lockbox.
Note
: If the lockbox shows no signs of activity and you cannot access
the key compartment, the battery is dead. You can use a power
paddle to provide a temporary charge to the lockbox and access the
battery compartment. Contact your Association to obtain a power
paddle.
