Please leave a note to tell us which key you need for your keyboard

Please check pictures carefully before you order. Lenovo ThinkPad T440 comes with several different models of keyboards. Key caps are not interchangeable if your laptop is using a different model of a keyboard. If you are not sure send me some pictures of a broken key cap or an area on a keyboard with a missing key cap. 

There are several different keyboards for Lenovo T440 04X0139 and 04X0101. I have inspected both keyboard and here is the way to distinguish one from another. Remove the trackball from your keyboard and inspect the part under it. 04X0139 has a square hole inside and 04X0101 the part is solid. Please refer to provided pictures. Key Caps are different for each model of the keyboard.
