I have installed Evo CHRT4 in my Grand Caravan 2018 with OEM key and it's working great. The CHRT4 was flashed for RF. I am now trying to install RF642W using RFA2A following steps on installation guide.
As per the last step on installation guide, I did press & release (-) AND press & release (lock) on RF642w fob, but on CHRT4 it did NOT blink RED and BLUE LED, instead the RED, BLUE, YELLOW LEDs stayed solid on. The fob would sound and show green light [after I press & release (-) and press & release (lock)].
The antenna LED fast blinks (BLUE). I checked wires and everything was good. Can someone help me resolve this? Thank you in advance.
