A small, rarely noticed screw inside your car’s steering column could be the difference between keeping your vehicle and losing it to thieves. Mechanic Iván Cabanas explains how this simple part quietly blocks one of the most common theft methods.
Iván Cabanas, a professional mechanic, points to a detail most drivers never notice: a single screw inside the steering column that quietly raises the bar for car thieves. While modern vehicles are packed with alarms and tracking devices, Cabanas argues that sometimes the most basic mechanical solutions are still the most effective.
Every car sold in Spain today is equipped with a steering lock that activates when the key is removed. This system, familiar to anyone who’s ever heard the telltale ‘clack’ as the wheel locks in place, is designed to prevent the car from being steered without the correct key. According to Cabanas, the heart of this system is the ignition barrel, which both accepts the key and triggers the lock.
This screw I have here makes sure it’s much harder to steal your car.
Thieves, he explains, typically have two options if they want to bypass the steering lock without a key: either break the locking mechanism or remove the ignition barrel entirely. The latter is often attempted by forcing a small security tab inside the column. If the thief has the correct key, the tab can be retracted easily. Without it, brute force is usually required.
This is where the hidden screw comes in. Cabanas describes how, on many vehicles, a special screw is installed from the opposite side of the column. When tightened to the correct torque, the screw head snaps off, leaving a smooth, rivet-like surface that’s nearly impossible to grip or remove in the tight confines of the steering assembly. This simple trick makes extracting the ignition barrel—and thus unlocking the steering—far more difficult and time-consuming for would-be thieves.
While car theft remains a significant issue in Spain, with around 25,000 vehicles reported stolen in 2025 according to industry data, small engineering details like this screw can make a real difference. As Cabanas notes, even as electronic security systems become more advanced, mechanical barriers still play a crucial role in everyday protection.
For drivers concerned about vehicle security, it’s worth remembering that not all threats come from high-tech hacking. Sometimes, the most effective defense is a piece of hardware no bigger than a fingertip. And for those who want to be prepared for other unexpected situations on the road, such as wildlife collisions, it’s useful to know the rules and risks—see this guide on what to do if you hit an animal while driving in Spain.
In practice, the presence of this breakaway screw means that even determined thieves face a much tougher challenge. It’s a reminder that, in the ongoing contest between car owners and criminals, sometimes the smallest details can tip the balance.
