Hi Carol. At the bottom is a small indentation where you put a coin or screwdriver and gently but firmly pry the top and bottom apart. Hope this helps.

I got my last one from Batterysharks.com. Item NB6-4.5. All you have to do is take it apart. take out the screws and the brace that holds it in and put the new one in. very easy. you can do a google search for that item as well. call 800-657-1303 or order@batterysharks.com

change the battery and try it again, and the battery has to be the same model

yes the battery can be replaced, and it is hard to open it up. I had to ask my husband how to do it.

You change the battery by unscrewing the screw by the bulb area where the number cr2032 is... Using a small Philips head screwdriver. Hope this helps.

Remove the orange protective cover. Then you will see the battery compartment which requires a Phillips screwdriver to open.

Actually there is a way to replace batteries, to open unit locate 2 short screws at the "cork" end. Taking those out will allow you to remove brushed metal end. Then on the side is 4 spots of rubber which cover 4 longer screws. Now be careful you don't dump out contents but now the unit halves open up. You will see a battery pack that is connected to a printed circuit board. Either unsolder off the circuit board OR snip and strip the wires and attach new battery which if you search on Google the printed specification of the battery.. Simple

Connie, I'm honestly not sure. We tried to pry it open, because you can see a battery in there. I suppose you can change it- if you can get to it! Seems impossible to open.

You merely remove both small screws, take off the cover, take out the old batteries and insert the new. Watch what direction the writing on the old batteries face so you insert the new ones properly.

Yes, it isn't really that difficult, but it is a little unique. You have to take out the key part, which is the same way you would change the battery. Then you will have just the old shell and the circuit board. There is a little hole in the front of the circuit board thing (in the yellowish part) and there are two holes about evenly spaced on the green part of the board. What I did was use a metal tooth cleaning device (like a pick) and pried the board out by first pulling on the front slot in the yellow part, then I used the hook of the pick to get into one of the round holes in the board itself and pulled it the rest of the way out. Use firm, but gentle pressure. I figure if I broke one hole I would still have the other one. Just be careful, take your time, and be gentle. I'll try to include a pic if possible.

You have to pry open the bottom portion of the unit itself to replace the 9V battery. I used a very small screwdriver to pry open the "tight" lid.

It is very easy: Undo the little screw located at the back of the case, open it, and carefully remove all the components (one by one) from inside. Keep an eye on the original position of these components so you can put them back in the new one. I would recommend to replace the battery as well. Once you finished installing the old components into the new case, just tight up the little screw and that's it!... It is ready to go.

You need to just take battery out and look at model number of the battery..

There is a section below the key pad. Take a flat bladed screwdriver and use it to slide the cover down to get access to the 9volt battery. Replace and your set to go.

Rebecca, just take a kitchen table knife, insert it in the slot in the bottom and twist it out. There are two batteries, so just slide them out and replace.

Use your thumb to open the door for the battery, pull the little white plug wire to disconnect the old battery. Plug in the new battery and close the cover door. Job complete

Turn off the laptop power. Then,slide and release the old battery before snap the new one in - there is only one way the battery can get in.
