Important iButton Keys:

Overview:

iButtons are NOT normally magnetic and will not affect credit cards, watches, or pacemakers.

They typically do not emit radiation of any kind. Stainless steel iButtons are normally pressed

into colored plastic tags at the factory to make identification and use easier. Key-fob tag colors

available are white, yellow, pink, red, orange, blue-green, dark-green, purple, or black. Since

all stainless steel iButtons are identical in size and shape they can be provided in any of the

available color key-fob tags by special order. However, there are various default colors for

various key types if a particular color isn't specified when ordered from the manufacturer or

distributor.

If in doubt as to the actual key type, you can identify the iButton model number by looking on

the metal end cap with a magnifying glass. The model number beginning with 'DS-' is

imprinted there. Some iButtons contain special functions such as digital memory or real-time

clocks, while others merely identify specific users.

The following list contains the most commonly used iButtons:

1. DS1990 – User Key, each key has a digital serial number that cannot be duplicated.

Once programmed into lock memory as a valid user, can be used to lock or unlock

locks. (Default key-fob colors: red, yellow, black, orange, dark-green, brown)

2. DS1904 or DS1994 – Contain an on board real time clock used to reset the lock internal

clock. Either one can be generally used interchangeably with the locks and software

(Default key-fob color: Blue-Green)
