2020 Jeep Gladiator adds proximity key (aftermarket key) success with Autel IM508/IM608. Pure obd2, no 12+8 adapter. No AutoAuth. Sharing is caring.
I had the 12+8 cable in hand. Poked my head under the dash, found the secure gateway module and nothing was plugged into it. So back to the obd2 and went through just fine. There is a trick during the key learning process though that autel does not mention.
I did this vehicle today. Read Pin no problem and learned key. All functions work (remote, proximity & vehicle start).
The new key is learned by putting it up to the start button, pressing and holding it there while clicking the unlock button on the FOB.
When the programmer tells you to put the new key up to the start button and press in and hold, it counts down from 30 seconds and fails to learn. The trick is to continually press the unlock button on the FOB while you hold the key pressed against the start/stop button. Door locks will click indicating learning is complete.
Like I said, I had the 12+8 with me in hand ready to plug it in. But on this truck, it was not needed.
