Special care should always be used when entering your code. The keypad is protected with a tough polypropylene material that makes a puncture unlikely, and impossible for dust and debris to interfere with the operation of the push-button keys.
The new plastic dome design is superior to metal domes and will continue to function even if the dome is damaged and collapsed. Our laboratory testing has surpassed 500,000 code input cycles with no failures using a pointed input tool, similar to a ballpoint pen.
Although wear was noticeable after this extensive testing, the lock remained operational. In actual operation, changing codes periodically will prevent noticeable keypad wear.
