Thank you for your reply AvoK95 and beezer, I read the description on Aliexpress of the remote I bought, that's what they said
Aliexpress wroteBefore buying,please confirm whether your remote control can be copyed or not.
Our remote control can copy the fixed codes and learning codes
rather than stealth codes.It can't copy original car remote control, two-way remote control and rolling code remote control (Rolling code chips start with HCS commonly,such as HCS200,HCS201,HCS300,HCS301,etc
It seems that my original remote has the rolling code feature (some sort of encryption) (Shown in the image linked in the first post)
What do you recommend to do? Is there any trusted shop that can assist me?
@AvoK95, I will check if the receiver has a pairing button tomorrow
Thanks
