Type 1 – The RED key has a distinct ID code which is then paired to a specific vehicle’s immobiliser control unit. This enables it to be re-programmed, and either adds additional programmed keys or deletes ID codes of lost keys.

Type 2 – This system gets the transponder ID code directly from the immobiliser receiver. It compares it to a maximum of five codes stored in its memory. If this is accepted, then the fuel system is energized and the engine starts. If it is not recognised however, the fuel system the engine won’t start.

Type 3 – These systems employ an amalgamate immobiliser control unit-receiver. It is located around the ignition switch, and if a programmed key is inserted, the immobiliser will be energised. This is then compared against five codes in its memory, and if the code on the key is accepted, the engine will start.

Type 4 – This produces a rolling-type code once the key is inserted into the ignition switch, through an electronic circuitry.

TIP: It is important that you do not attempt to use a red Honda master key to drive the vehicle as it is solely intended as a programming key. Here at Car Keys Solutions, we can provide you with a duplicate or replacement even without the master key. If your car was produced after 2000, we will obtain the codes from the Dealer in order to cut and programme your key while you wait.
