What is the biggest drawback of keyless entry?
2 Answers
The biggest drawback of keyless entry systems is that they usually require modifications to the original vehicle wiring, posing potential safety hazards. Below are specific advantages of keyless entry systems: 1. Electronic key encryption system cannot be replicated: Utilizing fourth-generation Radio Frequency Identification (RFID) chip technology, the keys cannot be duplicated, and official replacement requires legitimate documentation. 2. Whole-vehicle anti-theft: By locking the circuit, fuel system, and ignition in three points, the vehicle cannot be started even if the anti-theft device is illegally removed. 3. Automatic window closing: When the owner exits the vehicle and forgets to close the windows, there is no need to restart the engine to close them individually. The vehicle's security system will automatically raise the windows, enhancing the car's security level.
As an average daily driver, I always find keyless entry systems the most annoying due to their significant security risks. On the surface, it seems super convenient—just having the key in your pocket automatically unlocks the car. But I've heard plenty of cases where thieves use signal interceptors to clone the key fob and steal vehicles. Last year, my friend's car was stolen overnight from his apartment parking lot due to exactly this vulnerability—it's completely unpredictable. The signals can penetrate walls from dozens of meters away, meaning thieves might be scanning nearby, making parking in secluded spots downright nerve-wracking. While newer cars have improved anti-theft measures, older models have more loopholes. I'd suggest manually checking if doors are locked rather than relying solely on the indicator lights. Also, keeping a Faraday pouch for your keys to block signal leaks is a minor hassle compared to losing your entire car—safety should always come first. Don’t trade seconds of convenience for major losses.
