Copied as i have the same problem and cannot find an answer
I cannot connect my smart remote to my TV (UN50MU6300FXZA). The on/off button will power the TV, but when I press any button the TV says "Connecting to the keyboard..." and then says it failed, and asks me to press the pairing button on the keyboard.
I've pressed the back and play/pause button to pair, and I've tried taking out the batteries and holding a button for 20 seconds to discharge them. I'm also using brand new batteries. In fact, all the problems started when the original batteries died and I replaced them.
I also tried running the TV through the setup.

I do apologize for the inconvenience this has caused. I recommend reaching out to our remote management department at 1-800-Samsung.

This is a huge problem on expensive samsung TVs. The remote is junk, and the TV become useless because the remote is VERY unreliable.
