Okay so I just got a 2002 mustang gt I’ve been upgrading and today I decided I’d try to do the keyless entry programming by turning the key forward and backwards 8 times and the 8th ending on run but my door locks were not cycling to be in programming mode so I couldn’t get my fob to work. Any suggestions?

 

I keep seeing people view my post but could someone give me some advice I don’t want to have to take it to a dealer
