Remote Keyless Entry
This hand-held radio transmitter allows you to do
a number of functions. These include: closing and
opening the tonneau cover, locking/unlocking the
tonneau cover latch. All these within a 30meter range of
the vehicle.
To Lock/Unlock Latch:
Press and release the LOCK button on
the Transmitter once to unlock. Press
and release the LOCK button on the
Transmitter again to lock.
To Open Tonneau Cover:
Press and release the OPEN button on the Transmitter once to trigger
the Open Procedure.
To Close Tonneau Cover:
Press and release the CLOSE button on the Transmitter once to trigger
the Close Procedure.
Notes:
If any of the buttons are pressed and not released within a 30 second duration the
Transmitter will stop transmitting and shut down to prevent battery drainage.

KeyFob Power Supply
The KeyFob operates on a 3V Manganese Dioxide Lithium Coin Battery (CR2032).
Minimum operating voltage is approximately 2.2V, if the voltage drops below this level
the transmitter will cease operation, and the battery will need to be replaced. Please
replace battery with the aforementioned part number.
With the transmitter buttons facing down, use a thin coin to pry the two halves of the
transmitter apart.
Remove and replace the batteries. Avoid touching the new batteries with your fingers.
Skin oils may cause battery deterioration.
Do not touch the printed circuit board or the battery terminals that are on the back
housing.
To reassemble the transmitter case, snap two halves together. Make sure there is an even
‘gap’ between the two halves.
Test Transmitter operation.
