I’ve had an on again off again issue with my iPad Pro Smart Keyboard not wanting to stay connected. Sometimes it will just disconnect and the on-screen keyboard will pop up and then at other times I will get a pop up message saying “This accessory is not supported by this device.” At first I would only have keyboard connection problems every once in a while (maybe once a month) and then it started happening once a week and eventually multiple times a day. At first I could just disconnect the keyboard from the smart connector and re-connect it and it would solve the problem. But as the frequency of the issue increased this no longer worked. So it was time to get to the bottom of the problem.
I did a little digging and one of the most common fixes is to clean the smart connectors on both the iPad and the Smart Keyboard, but in my case that didn’t help.
After a little more digging I found out that Apple had issued an internal memo that acknowledged the problem and extended the warranty by 1-year. So I took a trip to the Apple Store. I explained what the issue was and the Apple Store Genius didn’t even want to see the problem in action, he just started the process of getting me a new Smart Keyboard. The hardest problem about getting the Keyboard replaced was waiting on the Genius to extract the serial number off of the keyboard. The serial number is printed on the Smart Keyboard but it is on the felt surface which makes it pretty much impossible to read. So they have to do a diagnostic on the iPad to get the diagnostics report to spit out the serial number of the attached keyboard.
Bottom line, if you are having connection issues with your iPad Pro Smart Keyboard go into an Apple Store or give Apple Support a call. It’s a known issue and you should be taken care of.
