this one works together with ak300? or is it a must for cas 4 key programming?

This one is mainly used to test if the key you programed match the CAS4 or not. If you do not have this tool, you need to install CAS4 to your car, then use the the new key to test if it works or not. If does not work, you need to remove cas4 from your car again, then program the key again. With this test, you can directly test the new key on this machine and CAS4. If match, then can directly install CAS4 to your car to use the key, if not match, you can program the key again.
