Q: The centre button of my 1500iEURD is stiff and gets stuck, how can I open my padlock ?

A:

The 1500iEURD lock is sensitive and reads all movements; certain types of touch seem to work better for some users to help ensure the correct combination is entered. Please try these suggestions: Give the shackle two quick squeezes to "clear" it rather than two slow, deliberate squeezes. In a quick manner, allow the button to move back to center mostly on its own, without over-guiding it. Don’t allow the button to bounce past the center position or it will read the adjacent position as part of the entry.
