Iván Cabanas, a professional mechanic, points to a detail most drivers never notice: a screw used in some steering-column assemblies that can make tampering more difficult. Modern vehicles may combine mechanical components with electronic security systems, but Cabanas says a basic physical barrier can still help protect the steering lock.
Many vehicles have a steering lock designed to engage when the basic is removed, preventing the steering wheel from turning freely. The mechanism is linked to the ignition barrel, which accepts the basic and, in designs using this arrangement, operates the lock. Construction varies by vehicle, so the screw Cabanas describes is not a universal feature of every car sold in Spain.
Cabanas explains that attempts to bypass a steering lock may involve damaging its mechanism or interfering with the ignition barrel. In some designs, a security feature inside the steering column restricts access to the barrel. Components and procedures differ by vehicle, and work on the steering assembly is best left to a qualified mechanic.
On some vehicles, Cabanas says, a special screw is fitted from the opposite side of the steering column. Its head is designed to break away when tightened to the specified torque, leaving a smooth, rivet-like surface that is difficult to grip in the confined space around the steering assembly. This can make removing the ignition barrel more challenging, although the screw’s presence alone does not show how much it changes the overall risk of theft.
The screw is one possible mechanical anti-tampering feature alongside the other security measures fitted to a vehicle. Its design and role depend on the particular steering-column assembly, so claims about its effectiveness cannot be generalized across makes and models.
For drivers concerned about vehicle security, the broader point is that protection can involve both electronic systems and physical components. Those preparing for other unexpected situations on the road, such as wildlife collisions, can also learn the rules and risks in this guide on what to do if you hit an animal while driving in Spain.
Owners should follow the manufacturer’s maintenance guidance and consult a qualified mechanic about the security features fitted to their vehicle. A small component inside the steering column may form part of that design, but its presence and function depend on the model.
