How do you get sky remote working when battreis are out for to long?

If the batteries in your Sky remote are dead for too long, the remote may lose its pairing with the Sky box. To fix this, replace the batteries with new ones, then press and hold the "Sky" button and the "1" button simultaneously until the LED light turns on, then release both buttons. Finally, press the "Sky" button again to complete the pairing process. If the remote still doesn't work, try resetting the Sky box or consult the user manual for further troubleshooting steps.
