Push any button to light up the padlock. The lighting is fairly dim through the waterproof cover, but essentially it's a standard numeric button layout with the unlock button bottom right.

Enter the pin you have (either member's pin, or the pin from your booking confirmation), then press the unlock button bottom right. If you've entered the pin correctly, you should hear an ascending series of beeps, and see a little green light flash at the top of the number pad. You can then pull the lock open.

If you hear a series of similar toned beeps and a red light flashes, then try carefully entering the code again. If it's an old booking code, it won't work and can't be re-used.

Please remember to lock the court after you've finished playing.
