I'm new to SDR, I'm trying to perform a replay attack that consists of unlocking a blocked car with hackRF ONE and the software gnu radio companion but the problem is that when I record the unlock signal, then I run the replay attack, it locks the car if it is unlocked and does nothing if it is locked. I want to clarify that I used as a frequency of 433 Megahertz. I would have liked to share my flowgraph but my reputation does not allow me. If anyone had a similar problem or know the solution to my problem, please share with me. Thank you
