Replacing the battery
The remote entry transmitter uses one coin type three-volt lithium
battery CR2032 or equivalent.
To replace the battery:
Integrated Keyhead Transmitter
(IKT)
1. Twist a thin coin in the slot of the
IKT near the key ring in order to
remove the battery cover.
Note: Do not wipe off any grease on
the battery terminals on the back
surface of the circuit board.
2. Remove the old battery.
Note: Please refer to local
regulations when disposing of transmitter batteries.
3. Insert the new battery. Refer to
the instructions inside the IKT for
the correct orientation of the
battery. Press the battery down to
ensure that the battery is fully
seated in the battery housing cavity.
4. Snap the battery cover back onto
the key.
Note: Replacement of the battery will not cause the IKT to become

battery replacement.
