glad to hear I am not the only one. I never had any key fob issues ever, I got the car with 3.3.5.
Since 3.4.1 and also the patch before, but 3.4.1 noticable worse, the car takes forever to unlock and lock. Pressing buttons on the key don't do anything for like 5-10seconds standing next to the car. Today it said key not detected in the car, but it still went into Drive ... so not sure what that was about.
I have two fobs with the Dream Edition. Both keys behave exactly the same and they have both the latest firmware. I did NOT put new batteries in, which I will do as a nextstep. But I can't imagine this changing anything, I got the 2nd key recently from Lucid.
Everything else is absolutely solid on 3.4.1, pisses me off that I never had any issues and now I do.
