The batteries and a QR code representing the Device Serial Number (DSN), are found inside the case of your Blink doorbell.
To change batteries, follow the instructions to open the case. If you have a wired installation, disconnect power before removing the doorbell from its backplate. This is to protect you from possible electrical shock by touching the exposed terminals.
To remove the doorbell from its back plate, use the Opening Key that came taped to the paper template in the product box.
Put the key into the opening at the base of the Blink Video Doorbell.
Lift, or pull the key 'toward' you while you move the doorbell up (toward the top, or camera side of the doorbell) to unseat the hooks and separate from the back plate.
Inside the battery case you can find the QR code and corresponding Device Serial Number (DSN), the reset button, and a diagram shows the correct position to insert new batteries.
Reconnect the doorbell to the backplate by lining up the pins and using a two step motion - press the doorbell against the backplate firmly (with moderate force), then push down to line up the bottom edges. You should feel a slight click when the doorbell is secure.
Press the doorbell button to test it.
For Outdoor and Indoor (gen 2) cameras, the batteries and Device Serial Number (DSN) sticker are found inside the back cover. The serial number is needed to add a device to a system. For automated convenience, we have added a QR code version of the serial number to scan with the Blink mobile app.
Before trying to remove the back cover, you must remove the camera from any mounts or accessories. This includes any third-party products.
Your camera shipped with a silicone disc covering the screw that secures the back cover.
The screw slot allows you to use the included opening tool/mount adapter unscrew the camera back. You can also use a coin, or flathead screwdriver.
A plastic sticker on the back of the camera shows the direction to turn. Turn left (counter clockwise) to open, and right (clockwise) to close.
Remove the film before camera use.
1. If it is present, remove the silicone protective cover from the fastening screw, and keep it for future use.
2. Use the included opening tool, to turn the screw counter-clockwise (turning to the left) until the screw spins freely.
3. Apply side pressure on the opening tool to gently pry the cover loose. As shown in the illustration, be careful to hold the camera on its side, to allow the cover to come off.
3.a. (Accessibility) Another way to remove the back cover after it is unscrewed completely, is to turn the opening tool around and insert the mounting end into the camera's back cover. Then, if you pull the opening tool gently, the camera's back cover comes off because the two are now attached.
1. Align the guide notches as shown, and gently hold the cover in place against the camera body.
2. Turn the screw clockwise (turning to the right) approximately three turns, or until snug. Take care to prevent over-tightening. The cover should be flush with the camera body when you are done.

2. You'll notice a grey switch with an arrow facing toward the bottom of the camera. Slide and hold that in the direction of the arrow.
3. While doing this, pull up on the battery cover with your thumb. This may require some force as the camera is air tight.
4. Lift the battery cover off of the camera.
That's it, you can now insert the batteries and access your camera's serial number (S/N).
