Per the instructions on the box, "simply remove screws from back cover and replace new batteries with correct polarity. I believe the battery is an LR44. It says "Operates on 3pcsxLR44 battery." It sounds like you need 3 of them. I have not opened mine yet.

There is a small Slot at the top of the casing that is easy to open with a small blade or screw driver or in fact, I can open it with my finger nail. Once opened you simply take out the small button battery and replace it, then simply snap the top of the casing shut. There is also a little diagram in the instructions explaining how to change the battery.

If you remove the battery, there should be a plastic strip underneath it to be removed. Once you do that and replace the battery, it should turn on. Hope this helps!

Hi Sherry, The easiest way to do this, I have found, is to take the opener with you to Batteries Plus. The guys behind the counter are really helpful -- They will not only find the right battery, but they will replace it and then test your opener before sending you on your way. And all you pay for is the battery. In case you are more of a do-it-yourselfer, you can pry it open yourself to change the battery. There is a very tiny indentation along the seam between top (the side with the buttons) and bottom. It lines up with the groove on the bottom where the clip snaps on (mine has a clip for keeping it on the visor in my car). The edge of a small screwdriver works well to pry it open (not phillips head, but the other straight edge type of screwdriver). After you've changed the battery, it should snap back on. Of course, if you can't get it to snap back on, those guys at Batteries Plus would probably snap it back on for you for nothing but a thank you and a smile, even if you aren't buying any batteries that day.

Hi Toni. You have to remove the unit by twisting it counter-clockwise. Unplug it from the wiring. There is a lid on the bottom that you can flip open that exposes the 9V battery. Good luck!

I haven't yet had the need to replace the battery. I did however take a look at it yesterday as I was also curious and the only thing I can think of is using a straight screwdriver on the two screws (assuming they're screws) on the face of the device. You can see the battery within. There is no way they'd make a device you can't change the battery out on... it's gotta be it.

It is simple to replace the battery. You have to unscrew the battery cover, take the old battery out, replace the battery with the same type battery and then replace the battery cover.

I had the same issue. I am going to try to use a different five prong screwdriver to unscrew the battery. Good Luck!

My battery gave out after just slightly over a year. The little tool, made of what seems to be a hard rubber, strips the battery case so I have not been able to replace the battery. Anyone had any luck replacing the battery?

You need a small screwdriver, I believe a Phillips head, to open the battery compartment. You can replace battery. If it still doesn't turn on then you need to send back to replace.

It is a built in Lithium battery. So, I'm assuming no way to replace it. They are asking me to assume the charge of shipping and send a $9.95 check for possible repairs because mine stopped working. That would probably be what you would need to do if yours needed a new battery. Since I've had mine less than 6 months I'm not a happy camper. Probably will not send it back. (This is their idea of a guarantee, I guess.)

on youtube look for "Nexus 7 battery replacement". I used a small flat head screwdriver to open the back as shown in the video. The video shows a "special" tool.

Take out the battery and reinsert. If it still won't work use a fresh recharged one. If it still doesn't work you need to call them and probably need to have it repaired.

Very easy...turn the device over..there is a round cap with a slot in it..place a coin in the slot..turn it counterclockwise..the cap will pop off.. pry the battery out taking notice which side of the battery is facing up..replace the new battery the same way.. replace the cap. It is a good idea to check the battery in both the sending and receiving units..I own 3 of these.. and 2 of them had weak old batteries rite out of the box.. I really like them.

The battery cover is screwed in. It is closed with a single small screw and you would need a small screwdriver to open/close it.

There is no secret in opening the battery. You can open it with your finger nails. Buy battery online or from local shops like CVS.

Look at the edge of the knife, across from the gray lever for the pen. There is a little rectangular "door." Pry that out with a small knife or screwdriver. Then, use the same small tool (a jewelers screwdriver works nicely) to pry out the battery. Hope this helps.
