This guide will instruct you on how to install your LMS to Lock-S hardware upgrade.
Remove your current locks from the doors.
Unscrew the back plate on the front-facing part of the lock. The screws are in the indicated locations:
Unscrew the 2 screws under the motherboard which hold the faceplate in place, and then disconnect the marked cables.

Note, your motherboard may look slightly different, but the screws are in the same location.
Step 4)
Pull up on the front faceplate, it should slide out.
Step 5)
Insert the new (pre-assembled) faceplate.

Note: Ensure you move the metal bar from the old faceplate to the new one, and place it in position on the 2 small pins.
Step 6)
Screw the motherboard back into place in the same location you unscrewed at step 3, and insert the cables back in.
Ensure they are all the way in.
Step 7)
You may already have an old battery terminal.
The upgrade kit comes supplied with a new terminal and battery chamber.
Locate the battery terminal at center of the lock, pull it out, and disconnect it.
Step 8)
Connect the new battery terminal and put it in place as in (see: Step 7).
Step 9)
Insert the new battery compartment
Step 10)
Put the back plate of the lock back, and screw it into place (see: Step 2)
The lock should now be ready to be put back on the door.
