Battery Replacement: Blink doorbells are battery-powered (except the wired Video Doorbell model). Over time, batteries lose charge and need replacing. Most users remove the doorbell to access the battery compartment.
Wi-Fi or Sync Issues: If your doorbell keeps disconnecting or fails to send alerts, a physical reset and reinstallation can often resolve software glitches.
Home Renovations: Painting, siding repairs, or door replacements may require temporary removal of the doorbell.
Upgrading or Switching Models: You might be replacing an older Blink XT with a newer Video Doorbell and need to transfer the mount or start fresh.
Theft or Damage: If your doorbell was stolen or damaged, reinstalling a new or repaired unit follows the same process.

No matter your reason, the reinstallation process is similar across Blink models. However, always check your specific model’s requirements in the user manual or Blink support site before beginning.

Tools and Materials You’ll Need

Before you start, gather the following tools and materials to ensure a smooth installation:

Blink doorbell (with charged or new batteries installed)
Blink mounting bracket (original or compatible replacement)
Screws and anchors (usually included with the doorbell)
Phillips-head screwdriver (the one that came with your Blink kit works best)
Drill (optional, for harder surfaces like brick or concrete)
Level (to ensure the doorbell is straight)
Smartphone or tablet with the Blink app installed and logged in
Wi-Fi network name (SSID) and password
Electrical tape and wire nuts (only if replacing a wired doorbell)
Safety gloves and goggles (recommended for drilling or electrical work)

Pro Tip: Keep all original packaging and accessories in a safe place. Blink uses proprietary screws and brackets that aren’t always easy to replace at hardware stores.

Step 1: Turn Off Power (For Wired Installations Only)

If you’re reinstalling a Blink Video Doorbell (wired model), it’s critical to turn off power at the circuit breaker before touching any wires. Even though the voltage is low (typically 16–24V), there’s still a risk of short-circuiting or damaging the doorbell if wires are mishandled.

How to Safely Turn Off Power

Locate your home’s electrical panel (breaker box).
Find the circuit labeled “doorbell” or “front door.” If unsure, turn off the main breaker to be safe.
Use a non-contact voltage tester to confirm power is off at the doorbell wires.
Label the wires with tape (e.g., “Transformer” and “Chime”) so you can reconnect them correctly later.

Important: If you’re using a battery-powered Blink doorbell (like the Mini or older XT models), you can skip this step. However, if you’re replacing a wired doorbell with a battery model, you may need to cap and secure the old wires inside the wall to prevent electrical hazards.

Step 2: Remove the Old Mounting Bracket (If Necessary)

If you’re reusing the same location, you might not need to remove the old bracket. But if you’re switching models, adjusting the angle, or the bracket is damaged, follow these steps:

Removing the Bracket Safely

Use the included screwdriver or a Phillips-head to unscrew the bracket from the wall.
Gently pull the bracket away from the wall. If it’s stuck, wiggle it slightly—don’t force it.
If wires are attached (wired models), disconnect them carefully and cap them with wire nuts.
Fill any large holes with spackle or wall filler if you plan to repaint or reposition the mount.

Tip: Take a photo of the wiring setup before disconnecting anything. This makes reinstallation much easier, especially if you’re switching between wired and battery models.

Step 3: Prepare the New Mounting Location

Now it’s time to position your Blink doorbell for optimal performance. A poor installation angle or weak Wi-Fi signal can ruin the experience, so take your time here.

Choosing the Right Spot

Height: Install the doorbell between 48 and 60 inches from the ground. This ensures it captures faces clearly and avoids tampering.
Angle: The camera should face straight ahead or slightly downward. Avoid pointing it directly at the sun or bright lights, which can cause glare.
Wi-Fi Signal: Use a Wi-Fi analyzer app (like NetSpot or Wi-Fi Analyzer) to check signal strength at the installation site. If it’s weak, consider a Wi-Fi extender or mesh network.
Clear Line of Sight: Ensure there are no obstructions like plants, mailboxes, or overhangs blocking the camera or motion sensor.

Marking and Drilling

Hold the mounting bracket against the wall at the desired height.
Use a level to make sure it’s straight.
Mark the screw holes with a pencil.
If drilling into brick, concrete, or tile, use a masonry bit and wall anchors. For wood or siding, a standard drill bit works fine.
Drill pilot holes slightly smaller than the screws to prevent splitting.

Pro Tip: If you’re unsure about drilling, use adhesive mounts (like 3M Command Strips) for temporary installations. However, these aren’t recommended for long-term use or high-traffic areas.

Step 4: Install the Mounting Bracket

With the location prepared, it’s time to secure the bracket.

Attaching the Bracket

Align the bracket with the pilot holes.
Insert the screws and tighten them with the screwdriver. Don’t overtighten—this can crack the bracket or strip the screws.
Ensure the bracket is flush against the wall and doesn’t wobble.
If using a wired model, feed the doorbell wires through the center hole of the bracket.

Note: Some Blink models come with multiple bracket options (e.g., angled or flat). Choose the one that best matches your doorframe and desired camera angle. The angled bracket is great for recessed doors or uneven surfaces.

Step 5: Install or Replace the Batteries

For battery-powered Blink doorbells, this step is crucial. A weak or improperly installed battery is one of the most common reasons for installation failure.

How to Install Batteries Correctly

Remove the doorbell from the bracket (if already attached) by sliding it upward and pulling it away.
Locate the battery compartment on the back of the device.
Open the compartment using the provided tool or a small flathead screwdriver.
Insert two AA lithium batteries (recommended for cold climates) or NiMH rechargeables. Do not use alkaline batteries—they drain too quickly.
Ensure the batteries are inserted with the correct polarity (+ and –).
Close the compartment securely. A loose cover can cause power interruptions.

Battery Tip: Blink recommends lithium batteries for optimal performance, especially in temperatures below 32°F (0°C). Rechargeable NiMH batteries work well in milder climates but may need frequent recharging.

Step 6: Attach the Blink Doorbell to the Bracket

Now that the bracket is secure and the batteries are in, it’s time to mount the doorbell.

Mounting the Device

Hold the doorbell with the camera facing outward.
Align the slots on the back of the doorbell with the tabs on the bracket.
Slide the doorbell downward until it clicks into place.
Gently tug on the device to ensure it’s locked securely.

Warning: Do not force the doorbell onto the bracket. If it doesn’t slide in easily, double-check the alignment and bracket type.

Step 7: Reconnect to Wi-Fi and Sync in the Blink App

This is where many users get stuck. Even if the doorbell is physically installed, it won’t work until it’s reconnected to your Wi-Fi network and synced with the Blink app.

Syncing Your Doorbell

Open the Blink app on your smartphone or tablet.
Tap the “+” icon to add a new device.
Select “Doorbell” and follow the on-screen prompts.
When prompted, press and hold the sync button on the back of the doorbell for 5 seconds until the LED flashes blue.
The app will search for the device. This may take 30–60 seconds.
Once found, enter your Wi-Fi network name (SSID) and password.
Wait for the app to confirm successful connection. The LED on the doorbell will turn solid green.

Troubleshooting Tip: If the app can’t find the doorbell, move closer to your router, restart the app, or reset the doorbell by holding the sync button for 20 seconds.

Step 8: Test All Features

Don’t assume everything works just because the app says “connected.” Test each feature to ensure full functionality.

Testing Checklist

Live View: Open the app and tap “Live View.” You should see a clear, real-time video feed.
Motion Detection: Walk in front of the doorbell. You should receive a motion alert within 10–15 seconds.
Two-Way Audio: Tap the microphone icon and speak. You should hear your voice through the doorbell’s speaker, and vice versa.
Night Vision: Test in low light. The infrared LEDs should activate, providing a clear black-and-white image.
Battery Level: Check the battery percentage in the app. It should show 100% or close to it after fresh installation.

If any feature fails, revisit the troubleshooting section below.
