iButtons and iButton readers are not magnetic but are fully electronic. iButtons
are very resistant to water and shock. iButtons are also available in various types, and
when desired are installed in various colored plastic keyring tags. The color has no
particular meaning. Only DS1990 iButtons and user keypad codes are used as 'User keys'
when programming E4 / E5 locks via the keypad. (DS1977 iButtons are used to program
locks only when using PC computer software to program locks.)
It is not required to apply great physical pressure with an iButton on the reader,
only that the center portion of an iButton touches the center of the reader at the same time
as the outer portion of the iButton rests on the outer ring of the reader. This is most easily
done by holding the iButton against the reader slightly off center and at a bit of an angle.
On E4 model locks, the iButton
reader is located just below the
keypad on the front of the lock.
On E5 model locks, the iButton
reader is located just above the
keypad on the front of the lock.
