Transmitter Key Battery Replacement
The batteries for the key head transmitters
should be renewed at six monthly intervals to
ensure continuity of operation.
To replace transmitter battery:
a). Use a thin blade to prise apart the two
halves of the transmitter key head, and with-
draw the battery.
b). The transmitters are powered by a 3v
long life lithium battery type CR2032. With
normal use, this should last between 3 and 5
years. After opening the new battery packag-
ing, touch only the sides of the battery, and fit
the battery into the key case with the positive
side (+) upwards as shown.
c). Press the battery case together.
Disconnecting the Vehicle Battery
Before disconnecting the battery, ensure that the alarm system is disarmed.
On reconnection of the battery, the alarm will automatically be set. Have the transmitter ready to disarm.
