Once the electronic transponder is energized, the key sends its ID code to the immobilizer control unit-receiver, which checks the code against the codes stored in its memory. There is no direct electrical connection. It uses electromagnetic induction to energize the electronic transponder in the key. The immobilizer control unit-receiver is inside the bezel around the ignition switch. If you try to start the engine with a non-programmed ignition key, the engine cranks, but it does not start. The indicator keeps blinking until you turn the switch to LOCK (0).

If you insert a non-programmed ignition key into the ignition switch and turn the switch to ON (II), the indicator comes on for 2 seconds and then starts to blink. When you turn the ignition switch to LOCK (0), the indicator blinks for 5 seconds and then goes off. When you insert a programmed ignition key (master or valet) into the ignition switch and turn the switch to ON (II), the indicator comes on for 2 seconds and then goes off. The immobilizer indicator is on the instrument panel. For key cutting, use the appropriate tool, i.e Xhorse Condor Mini Plus key cutting machine.īecause of the rolling code characteristics of the Type 4 immobilizer system, you cannot use the Ilco Immobilizer Key Code Duplicator or Ilco programmable (T5) key blanks with this system. The keys without remote transmitters contain no batteries or other serviceable parts.īoth the master and valet keys used with this system are sidewinder-type keys. Some master keys have a battery-operated remote transmitter built into the grip that lets you lock and unlock the vehicle. The immobilizer system uses this code to determine whether to start the engine. The vehicle comes with two master keys (black grip) and one valet key (gray grip).Įach master key and valet key has electronic circuits in its grip that output a rolling-type code (set by the immobilizer control unit-receiver) when you insert the key into the ignition switch. Immobilizer system keys (two master keys and one valet key at new vehicle delivery).

The immobilizer system includes these components: Replacing the immobilizer control unit-receiver.Starting the engine without a programmed ignition key.Clearing transponder codes of lost programmed ignition keys.Hardware: MVCI original, VXDIAG Honda (with i-HDS 1.004.025), HDS HIM double-board (need luck)

The Type 4 system is different than previous systems in that the transponder ID code in the key is a rolling-type code instead of a fixed code. The i-HDS programming tutorial is for education purpose.Īll of the listed vehicles have a Type 4 immobilizer system that disables the vehicle unless a programmed ignition key is used.
