How do you replace a saxo 1.6 vts ignition barrel?

To replace the ignition barrel on a Saxo 1.6 VTS, first disconnect the car battery to ensure safety. Remove the steering column shroud by unscrewing the screws and carefully separating the two halves. Then, insert the key into the ignition and turn it to the "on" position; there should be a small release pin you can press to free the barrel. Finally, pull out the old ignition barrel and install the new one, ensuring it locks into place before reassembling the steering column shroud.
