How do i open the battery door on the M-888

From the owner's manual:

• Open front thermostat door and open battery compartment door.
• Install two new "AA" alkaline batteries. Locate the positive (+) ends of the batteries and match them with the positive (+) terminals located in the battery compartment. Close battery compartment.

Going by the photo of the thermostat, it looks like there's a finger recess or latch on the right side of the thermostat that you pull on to swing the front open. If there is unexpected behavior from the thermostat after replacing the battery, see the reset procedure in the installation section of the manual.

Jack, I have a Z981. When I examine the battery door, it appears to have two places where the door latches when you slide the latch to lock it. It may be that one or more of the metal tabs that fit into the two places to secure the battery door has become bent.
I cannot get the battery door latch to move if the door is open, but you should have no trouble identifying the two metal tabs that are used to hold the battery door closed.

The latches are "frozen" because of metal contracting in the latch or latch lubricant physically becoming more viscous or freezing and preventing movement of the latch. You may need to apply a sub-freezing lubricant to prevent them from freezing up in low temperatures. Best put the car into a garage and let the general higher temperature unfreeze the latches.

Was it just the dome light draining the battery? Next time, take off the neg. battery cable, or remove the bulb.
How far did you get with the panel? Once the panel is out of the way, you can open the door latch manually. Or maybe can put the inside handle back on to open door?

[ P.S., you remove the Bottom Door; you wear an ESD wrist strap, and have it's alligator clip attached to a good ground source; or you risk using the laptop for a Frisbee from now on, or a doorstop.
