Canon a1100is camera battery door replacement

Kurt- I have successfully completed a d-i-y battery door replacement on my Canon A1100IS, and I make no claims about being an "expert." My training was watching u-tube videos of guys disassembling digital cameras (other models). Here's how to open the case on the A1100is, which is not really much different than opening the case on most any compact digital camera.
Using a size #0000 phillips screwdriver (Sears sells a set of 6 minis--slotted and phillips--for $10), I removed the nine screws from the side and bottom of the case plus one inside the mini-usb cover and the one inside the battery compartment.
Then, I gently worked the front and rear of the case apart (the top of the case halves have two snap clips that hold them together. Unlike some cameras, the A1100IS does not have any flexible cable straps between its front and rear covers.
With the case halves removed, I then used a tweezers to move the straight end of the hinge spring out of its original place next to the tripod socket. That released spring pressure on the hinge and I could then easily remove the hinge pin with the tweezers.
Then, it's simply a matter of placing the replacement door's hinge/spring combo in the proper location and inserting the hinge pin to hold it there. I purchased a new door from Canon for $8.42 plus shipping). Then, I used the tweezers to position the straight hinge spring end in the slot next to the tripod socket.
The only thing left was to wipe my fingerprints off of the LCD screen and then gently replace the front and rear case halves--snapping the case's top together and then replacing the nine screws.
