It is very simple, you ask about the chip, I will say how to match the chip:
First, disconnect the battery from the negative terminal and reconnect it after about 10 seconds, at which time the double flash flashes.
Then go back to the cab (the door and the hood are not closed), plug in the key with the original car chip, insert it, wait 2 seconds, and then pull out, see the engine anti-theft light (below the left of the steering wheel) flashing once, reinsert the key, pull out 2 seconds later, and so repeatedly insert and remove 5 times.
After the fifth time, the anti-theft light becomes steady on and pull out the key. Insert the key to be matched, and remember to put the new chip in it. Just stick it in. No twisting. Learning. Wait a minute... Note: Keep the light on at this time! After one minute (just count to 60 seconds), pull out the key, insert the key of the original car, and turn on the ignition switch (start the car). Here, the match is complete ~ Turn off the engine, pull out the original car key, plug in the new key just matched to start a fire.
