I will choose to use USB cable to connect with KC501.

Two buttons’ functions need to be master:

The left button “FR” is for reading key remote frequency while the right button “TR” is for reading transponder ID and chip type.

Ok, let’s begin with the first test.

Test 1. Read remote frequency

Place the car key close to the transponder area->Press the “FR” button->read data

Please follow this procedure accordingly, super easy and super convenient, right?

I will use the VW key as an example to clearly show this procedure because all the keys are the same when reading remote frequency by these two devices.

One funny thing:

You can press every button on the key when reading its remote frequency, the testing data will never change.

Place the car key to the vehicle key slot of KC501-> Press the “TR” button->read data


We will use Range Rover key as an example to clearly show this procedure instead.
