Can Car Keys Be Modified?

[SanJordan]

Yes. Here is the relevant introduction: For models that still use traditional keys, if you want to upgrade to a smart key later, it's not as simple as modifying the key itself. A series of modifications to the car's original starting system are required. Currently, upgrading to a smart key one-button start system takes about 60-70 minutes. The technician will first remove the car's decorative panels, locate the position for installing the main unit, use a special bracket to secure the main unit, and connect the main unit's start group and power plug to the car's original lock. During the modification, the technician needs to dismantle the decorative panels under the dashboard to find the plug for the car's original "multi-path controller" and connect the main unit's wires one-to-one with the car's original wiring. Since this involves the car's original circuit, it is recommended to choose the original manufacturer's 4S store for the modification.
