How to matching a car key yourself--Process break down

Last article I introduce the basic theory of making a car key yourself(not OEM, check my profile to read that article), today I will break down the process, so we can go through the details and have a better understanding for how it works. The tool in this case is Topdon ArtiMini.

Preparation:
1.Battery level not lower than 12.5V during the whole process.
2.Each key’s remote signal matching process not longer than 15 seconds.
3.Doors and trunk lid are closed before starting.

Steps:
1.Ignition ON
2.Choose the correct car model on the pad, then choose central lock system
3.Choose Adaption and Matching-->remote control self-adaption
4.Input the key number you want to matching and save it, e.g. 2
5.Ignition OFF, pull out the key. And press the remote key button at least for 1 second but not longer than 15 seconds in sequence, when the door lock gives feedback, matching is done.

Looking through the whole process, it’s like let the car ECU and door lock recognize the remotes with the help of professional tool. All tech are integrated in one tool, actually there are very few difficult operation left for the people that conducting the process.
