This chip in the head of the key contains a unique identification number. The Cat ® electronic key uses the same key cut as the standard Cat ® key. The electronic key can be used to operate any machine that uses the current Cat ® keyswitch. The Cat ® electronic key comes in a gray color or a yellow color. Cat ® electronic keys are not configurable.The exciter coil of the MSS is a ring shaped device. The exciter coil is mounted around the existing Cat ® keyswitch. The exciter coil is used to read the ID that is contained in the Cat ® electronic key.Note: Ensure that you have only one electronic key near the exciter coil when the MSS reads the key. If more than one electronic key is near the exciter coil, the MSS3s ECM will not read the key and the machine will not start.The status indicator for the MSS is mounted in the dash of the machine near the keyswitch. The status indicator will give basic information about the MSS to the operator of the machine. The status indicator has two colors: red and green.
