Yes, keyless entry can be a security risk. Thieves can use devices to amplify the signal from your key fob and unlock your car. To mitigate this risk, store your key fob in a Faraday pouch, use a steering wheel lock, and turn off the fob when not in use if your vehicle allows it. Regularly update your car's firmware to benefit from any security patches.
