Your attempted job was on a 2003 Audi A3, which was the first to use the Can Chip with the precoded CS. Currently the 884 cannot tell the difference between a T6 ID48 chip and a Can chip, it will read both as MG10 and go through the cloning process. But if it is a Can chip system the procedure will give a fail message at the end. This is currently being addressed by Keyline.
Here’s how to check if you have a Can system or a Non-Can system. A good indicator is looking at the lights on the dashboard when you turn the ignition on. Vehicles with the Non-Can T6 ID48 system that can be cloned will have an immobiliser light.
If it does, it is likely that it will clone fine with the Keyline TKM head.The Can systems don’t use this immobiliser light generally, they use the term ‘SAFE’ instead on the dashboard if a programmed key is inserted.
This indicates a Can system and the majority of cars will not have an immobiliser light symbol at all. The VIN number will also confirm whether a vehicle is using a Can or Non-Can system. Look at digits 7 and 8 in the VIN number, as per example VW Golf VIN here: WVWZZZ1KZ7W193867. This tells you that the car has a 1K chassis, which is a new Can chip model that cannot be cloned yet. The 10th digit of the VIN confirms the tear of manufacture, which in this case is a 7 which means it’s a 2007 model. The following VIN number: WVWZZZ1JZ3B062197 is for a Non-Can model of VW golf that has a standard T6 ID48 chip that can be cloned. In this case the digits in positions 7 and 8 are 1J confirming that this is a MK4 1J chassis vehicle which can be cloned, digit 10 is a 3 which confirms it was built in 2003.
FOR AN AUDI A3, A T6 ID48 WILL HAVE 8L IN DIGITS 7 AND 8 OF VIN AND IS CLONEABLE. FOR AN AUDI A3 USING A CANBUS T25 CHIP, IT WILL HAVE 8P IN DIGITS 7 AND 8 OF VIN WHICH CONFIRMS IT’S A CAN SYSTEM AND SO CANNOT CURRENTLY BE CLONED.
The issue of the vehicle immobilising and failing to start after cloning has failed. In this case you have switched the ignition on and off 16 times with an unprogrammed key, the car thought this to be a theft attempt and immobilised itself. You must simply perform a soft reset procedure. Turn on the ignition to position 2 where the dash lights up and leave the ignition switched on with the original key for 45 minutes. After 45 minutes switch off and the key will now work fine.
