How do you re-key an ignition?

Re-keying an ignition typically involves removing the ignition cylinder from the steering column. Once removed, the current ignition cylinder is disassembled, and the tumblers inside are replaced with new ones that match the new key. After reassembling the cylinder, it is reinstalled in the vehicle, allowing it to work with the new key. Always consult your vehicle's manual or a professional locksmith for specific instructions related to your vehicle model.
