I just got my new basic fj without keyless entry this month. i came to a guy who can install the after market keyless for me, but i found there is a little problem with this thing. when i press the button to unlock the door, it took 2 sec to respond, so you have to wait there 2 sec to open the door. the guy says because it is a after market, it can't unlock as quick as OEM keyless. i don't believe this guy. so i am wondering is this problem can be fixed? thanks
