Many owners of Opel J GTC are asking how and where to make a new chip-a key for a car. The keys have the habit of getting lost or broken, which means that sooner or later a duplicate might be required.
Please note that the new Opel Astra J GTC chip can only be reset by an authorized dealer. He has to come up with documents confirming your ownership of the car. The "bolt" of the key for Opel Astra J GTC can be ordered directly from the dealer or bought in advance (the second option is cheaper).
