![]() Immobilizer and transmitter master key blank To add a key with the i-HDS, you need these items: NOTE: Refer to the parts catalog for the P/Ns, and search by VIN for the correct parts. The i-HDS rewrites the immobilizer control unit-receiver, storing the transponder code of the new key in the memory of the immobilizer control unit-receiver. Use the Honda Diagnostic System ( i-HDS) with Honda key blanks to add a key. If the serial codes are mutually recognized during this communication process, the ECM/PCMĮnergizes the fuel supply system so the engine can start. The immobilizer control unit-receiver, it communicates with the immobilizer control unit-receiver by sending back its own When the ECM/PCM receives the unique serial code from ![]() The ECM/PCM is an integral part of the immobilizer system. But if the transponder ID code does not match, no serial code is sent, and the vehicle won’t start. If the codes match, the immobilizer control unit-receiver sends a unique serial code to the ECM/PCM. 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.

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.
