How does the Secure Keyless entry system in the Audi A5 work?

Can you provide a clear explanation of the keyless entry system in the Audi A5, especially in terms of security and reliability?

The Audi A5's Secure Keyless entry system uses a unique wireless signal to communicate with the car's sensors, allowing the doors to be unlocked or locked with the push of a button. This system provides an added layer of security as the signal is encrypted and cannot be easily hacked or cloned by thieves. My personal advice is to always keep your key fob secure and out of sight to prevent potential hacking attempts.

The Secure Keyless entry system in the Audi A5 is based on a rolling code technology. This means that the code changes every time you unlock or lock the car, making it nearly impossible for someone to intercept and replay the signal. As an extra precaution, it is recommended to periodically change the code manually by pressing the lock and unlock buttons on the key fob at the same time. This will further enhance the security of your car.
