The transmitter integrated into the key is used instead of the key holder type. The transmitter integrated into the key offer the following advantages.

• The transmitter is integrated into the master key. The 3-knob button is used, and the specific secret code is transmitted as a radio wave signal.
• A brilliant silver Three-diamond mark is stamped on the back side of the key grip.
• An indicator light, which illuminates when signals are received, is added on the key grip. This indicator lamp informs you of the signal transmission status and warns you of a flat battery in the transmitter.
• A signal transmission circuit (printed circuit) and a battery are housed in one case. The case is housed in the key grip, thus improving resistance to water intrusion.
• The functions of the immobilizer system are integrated.
