In Symmetric Key Cryptography domain, Automatic Variable Key (AVK) approach is in inception phase because of unavailability of reversible XOR like operators. Fibonacci-Q matrix has emerged as an alternative solution for secure transmission with varying key for different sessions [

]. This paper attempts to analyze symmetric key cryptography scheme based on AVK approach. Due to key variability nature, the AVK approach is assumed to be more powerful, efficient and optimal but its analysis from hackers’ point of view is demonstrated in this paper. This paper also assumes various situations under which mining of future keys can be achieved. The paper also discusses concept of Key variability with less probability of extracted result under various scenario with the different degree of difficulty in key mining.
