Logitech’s K270 keyboard is a popular ergonomic keyboard with an amazing two year battery life. It is also sold as part of the MK270 keyboard mouse combo.
It connects to a laptop or PC over a wireless 2.4 GHz link. A USB dongle plugs into a laptop or PC and is used to establish this link. This is a small receiver that’s easy to misplace or lose.
What if you lose the dongle for the K270 Keyboard?
You might think the keyboard is useless now. However that’s not the case. The dongle can be replaced. You just have to get the correct one.
The first step is to look for the Manufacturer’s part number – under the keyboard.
If you have the older Y-R0042 product, shown in the picture above, you will need a non-unifying or nano-receiver. Pick the one that works with the MK270 as that’s the same one.
If on the other hand, your K270 keyboard has a serial number Y-R0015, it will work with a Unifying receiver and the lost dongle can be replaced with a Unifying receiver dongle with an orange marking on it.
The newer K270 keyboards are part of the Unifying family of products and that’s an advantage for many reasons. Replacement unifying receivers are readily available and it’s a breeze to connect multiple Logitech products simultaneously that are compliant with this ecosystem.
In this post we have recommended a solution in the event that you lost the USB dongle receiver for your K270 Keyboard or MK270 keyboard/mouse combo. Depending on the keyboard serial number, you will need either a Unifying Receiver or a Nano-receiver.
Note that the MK270 keyboard/mouse combination uses a nano-receiver. Here’s what to do if you lose that.
