I have the interior canister taken out - you can see the battery should go inside that, but this cannister does not open no matter how i look at it - i can usually assemble most things and figure out stuff like this but i am baffled - is this just so...

With the device fully assembled the end cap - the piece of metal surrounding the orange on/off button - will unscrew by turning it counter-clockwise while holding the boy of the light in the other hand. The AA battery goes on + end first. Good luck. SL

We had the same problem. It seems you have to press in on the latch, and down on the top in order to get it to open It was impossible for my wife to open it, and I had a hard time. I finally kneeled on the top to put more weight on it, and it opened. We are going to leave it open for now, until we go on our next extended trip. Try the Sentry website; they may have other opening suggestions.

if you look carefully on the side of battery slot you have a plastic cover that you can open.Open that and take the line through that and close the lid!hope it helps you!

Hi Ellen, There is a battery inside just not sure how to get to it. Mine worked fine for a week then just stopped working. Next time I clean and put in new tablets Ill see if there is any way to take it apart and see what went wrong. Maybe a bit of water got inside, rust, short, lose wire, dead battery, etc. Hope someone else was able to get inside and can tell us. So many have the same problems you'd think the manu would step-up and help us all?

Flip the bottom over and try to snap in. (could be upside down) I tried the first way too, looks like it should be the inside but it isn't. After turning it, it snaped in easy. (little pressure) then slide one side at a time and snap in place. The only complicated part to me was the lid, make sure to get the hindges in.

Mine worked fine, plugged it in and it worked. How about this (I'm no expert, just troubleshooting) make sure all parts are assembled properly and make sure your top lid is locked down securely. If u have followed all directions according to manual you may have to return for new one. Hope this helps :-)

It sounds like your battery door is not properly closed. Open it using the slide latch on the bottom edge of the unit. Open & remove the battery door. Make sure the top is properly indexed into the case and then firmly press it shut.

There is a small gap between the battery slide and the handle. I used a small screwdriver to push down just above the arrow in the gap. There is a small plastic hook there that slides up under the handle portion when closed and once it is pushed down you can slide it open. Hope this helps.

It is really hard to open! On one side of the battery cover there is a little tab and you push it over toward the center and you pull the cover back at the same time! You can push the little tab over with a small straight screwdriver if you can't get to it with your finger!

Thanks Brianlatz! I swear I couldn't figure out how to put the battery in so I finally just decided to shove it in. But then the little ring wouldn't fit. Now I can't take it out. I thought there must have been an easier way. Thank god for google which led me here. lol. Geez. How the hell am I going to take the battery out now???

Do you have fresh batteries? Maybe you don't have it on the can properly. Other than that I've no idea why it doesn't work.

You must have a defective one..had no problem opening mine. Turn counterclockwise.

The bottle just snaps in, but I have the same problem. I thought my canister was empty but it's just the machine. In fact I don't even use it anymore. I wish I had bought it locally so I could return it. ..

You've got to put the opener ON TOP of the can, not on the side. Squeeze, then turn the crank until it gets easier to turn (at least once around.) Release and use the built in pliers/gripper to pull the can off.

The battery pulls out. So to me theirs no reason to open it up unless you remove the front sticker. Ill just buy another one

I put the whole thing together before putting batteries in and now cannot take apart the piece that holds the batteries. I'm sorry, no help here. I'm trying to figure it out myself before my daughter grows out of it. Good luck!

You're going to need to open it to put the battery in. It opens by twisting neer the bulb. If it will not open return it
