The three ways to connect a keyboard to a tablet

A keyboard connects to a tablet in one of three ways: Bluetooth wireless, a USB cable, or a physical connector port built into the tablet. Bluetooth is the most common because it works with nearly every tablet made in the last five years and requires no cables. USB works if your tablet has a USB-C or micro-USB port and you have the right adapter. Physical connectors—like the iPad's Smart Connector or older Samsung DeX docks—only work with specific tablet models.

Which method you use depends on what tablet you own, what keyboard you have, and whether you want to move around while typing. Most people start with Bluetooth because it is wireless, costs nothing extra if you already own a compatible keyboard, and pairs in under a minute.

Key Takeaways

  • Bluetooth keyboards work with almost any tablet and pair through your tablet's Settings menu in under two minutes.
  • USB keyboards need a USB-C or micro-USB adapter and work best if your tablet stays in one place.
  • Some tablets like iPads have built-in Smart Connectors that connect to keyboard cases without Bluetooth or USB.
  • Once paired, a Bluetooth keyboard reconnects automatically when you turn it on, so you only pair once.
  • If your keyboard does not appear in your tablet's Bluetooth list, restart both devices and try again.

Connecting a Bluetooth keyboard to your tablet

Turn on your Bluetooth keyboard and put it in pairing mode. Most keyboards have a button labeled "Pair" or "Connect" that you hold for three to five seconds until a light blinks. Check your keyboard's manual if you cannot find the button—some keyboards pair automatically when you turn them on.

On your tablet, open Settings and find the Bluetooth menu. On iPad, go to Settings > Bluetooth. On Android tablets, go to Settings > Connected Devices > Bluetooth or Settings > Bluetooth (the exact path varies by brand). Turn Bluetooth on if it is not already on. Your tablet will show a list of devices it can see.

Look for your keyboard's name in the list and tap it. Your tablet will ask you to confirm the pairing. Tap "Pair" or "Connect." The keyboard and tablet will exchange a code, and within a few seconds the keyboard will show as "Connected" in your Bluetooth menu. You can now type on your tablet.

If your keyboard does not appear in the list, restart both devices and try again. Make sure the keyboard is in pairing mode and within three feet of the tablet. If it still does not show up, check whether your keyboard is already paired to another device—most keyboards can only pair with one device at a time, though they can switch between paired devices.

Connecting a USB keyboard to your tablet

USB keyboards work with tablets that have a USB-C port (most Android tablets made after 2015) or a micro-USB port (older Android tablets and some budget models). iPads do not have standard USB ports, so this method does not work for them unless you use a third-party USB adapter.

Plug your keyboard's USB cable into a USB-C or micro-USB adapter, then plug the adapter into your tablet's charging port. Your tablet will recognize the keyboard when ready—no pairing needed. You can start typing right away. Some tablets will show a notification asking whether you want to use the keyboard; tap "Yes" or "Allow."

The downside is that your tablet's charging port is now occupied, so you cannot charge your tablet while using the keyboard. If you need both at the same time, use a USB hub with power delivery, which lets you plug in both the keyboard and a charging cable. These hubs cost between fifteen and forty dollars.

Using keyboard cases with built-in connectors

Some tablets come with or support keyboard cases that use a physical connector instead of Bluetooth or USB. iPad Pro models have a Smart Connector, a set of three metal pins on the back that connect to compatible keyboard cases made by Apple and third-party manufacturers. Samsung tablets with DeX support use a similar connector on the back or bottom.

To use these keyboards, straightforward slide your tablet into the case or align the connector pins and push gently until you hear a click. The keyboard powers on automatically and requires no pairing. These cases are more expensive than standalone keyboards—usually sixty to two hundred dollars—but they are designed to fit your specific tablet and often include a stand.

Check your tablet's manual or the manufacturer's website to see whether it has a Smart Connector or DeX port. If it does not, you cannot use these keyboard cases, and you will need to use Bluetooth or USB instead.

Troubleshooting a keyboard that will not connect

If your Bluetooth keyboard pairs but does not type, restart your tablet. Go to Settings, tap Power or Restart, and turn the tablet off completely, then back on. Once it restarts, open Settings > Bluetooth and check whether your keyboard is still listed as connected. If it is, try typing. If it is not, tap the keyboard name and select "Connect" again.

If your keyboard pairs but only types numbers or symbols instead of letters, your tablet may have a different keyboard layout selected. Go to Settings > Language and Input (or Keyboard on iPad) and make sure the layout matches your keyboard. For example, if you have a QWERTY keyboard but your tablet is set to DVORAK, the keys will not match.

If a USB keyboard is not recognized, try a different USB adapter or cable. Some adapters do not work with all tablets, and some cables are damaged. If you have access to another tablet, test your keyboard on it to confirm the keyboard itself works. If it does, the problem is with your tablet's USB port or settings, and you may need to contact the tablet manufacturer.

If your keyboard was working and suddenly stopped, check whether it is still charged. Wireless keyboards run on batteries, and a low battery can cause connection drops. Replace the batteries and try pairing again. If the keyboard still does not work after new batteries, the keyboard may be failing and may need to be replaced.

Switching a Bluetooth keyboard between devices

A Bluetooth keyboard can be paired to multiple devices but can only connect to one at a time. Once you pair it to your tablet, you can also pair it to your phone, laptop, or another tablet. To switch between devices, turn off Bluetooth on the device you are leaving and turn it on on the device you want to use.

Some keyboards have a button that lets you switch between paired devices without turning Bluetooth off. Check your keyboard's manual to see whether it has this feature. If it does, press the button and your keyboard will disconnect from the current device and connect to the next one in its list.

If your keyboard will not switch devices, unpair it from the device you no longer want to use. Go to Settings > Bluetooth, find the keyboard, and tap "Forget" or "Remove." Then pair it again to the new device. This takes about a minute and ensures a clean connection.

Frequently Asked Questions

Can I use any Bluetooth keyboard with my tablet?

Almost any Bluetooth keyboard will work with any tablet that has Bluetooth, including iPads and Android tablets. The keyboard does not need to be made by the same company as your tablet. Budget keyboards, gaming keyboards, and keyboard cases all work the same way—they pair through your tablet's Bluetooth menu and type when ready.

Do I need to charge a Bluetooth keyboard?

Yes, Bluetooth keyboards run on batteries (usually AA or AAA) or have a built-in rechargeable battery. Check your keyboard's manual to see which type yours is. Battery keyboards last three to twelve months depending on how often you use them. Rechargeable keyboards need to be plugged in every few weeks.

What if my tablet does not have Bluetooth?

Very old tablets (before 2010) may not have Bluetooth. If yours does not, use a USB keyboard instead. Plug it into your tablet's USB port with an adapter if needed. If your tablet has neither Bluetooth nor USB, it cannot connect to a wireless keyboard, and you will need to use the on-screen keyboard.

Can I use a keyboard and a mouse at the same time?

Yes. Pair your keyboard through Bluetooth, then pair your mouse the same way. Your tablet will recognize both devices and let you use them together. Some tablets work better with mice than others—iPads have full mouse support, while Android tablets vary by brand and model.

Why does my keyboard keep disconnecting?

Bluetooth keyboards disconnect when the battery is low, when they are too far from your tablet (more than thirty feet), or when another device is interfering with the signal. Replace the batteries first. If that does not work, move closer to your tablet and away from microwaves, routers, and other wireless devices. If disconnections continue, unpair and re-pair the keyboard.
