8 tips to prevent keyless car theft

The essence of keyless entry is that when we approach within about one meter of the car or touch the door handle, the vehicle sends out a radio signal. If the key fob is within range, the door unlocks. Unfortunately, this is exactly what car thieves exploit. They use signal-relay devices that can detect the signal from the key fob even from outside a building and then easily transmit it to the car. As a result, the car believes that we are standing right next to it.

Although car keys differ by manufacturer, in some models the signal transmission can be switched off. Don’t look for an obvious button—finding this function usually requires checking the vehicle’s user manual or asking a dealership. It is especially worth “turning off” the key if, for example, you go on holiday and leave the car at home for a longer period.

Since the range of keyless technology is limited, the farther you keep the key from the car, the more difficult you make the thieves’ job. Keep the key as far away as possible from doors and windows. Experts recommend at least five meters of distance from the vehicle.

Instead of hanging the key next to the door or leaving it on a table, place it in a metal-lined Faraday key pouch, sleeve, or box. This shields the signal so thieves cannot amplify it from outside the building.

If you want to be extra cautious, don’t focus only on the radio signal. You can also physically block your car’s movement with a steering wheel lock or by blocking the driveway.

Due to thefts, car manufacturers develop new technologies every year—such as new frequencies, software, and keys. That’s why it’s worth visiting a dealership from time to time to make sure your vehicle’s software is up to date.

Consider installing a tracking device (tracker or tag) as well. It should be placed in a hidden location, such as the glove compartment, under the dashboard, or under a seat, so thieves don’t notice it immediately. If the car is stolen despite all precautions, this greatly increases the chance that it will be recovered quickly and, ideally, undamaged.

Although proper insurance won’t stop thieves, it’s important to check what situations your policy covers and what the compensation conditions are in the event of car theft. Many insurance policies do not specifically address keyless theft. It’s also important never to store the vehicle’s documents or keys in the car, as these must be presented to the insurer during the claims process.

Last but not least, don’t forget basic car safety rules: park in well-lit, secure areas, and don’t leave valuables on the seat or in other visible places. After locking the car, always check that all doors are properly closed and all windows are fully up.
