Yeah the quality definitely seems to vary by manufacturer. My wife's vehicle would work about half the time, only after a delay. More annoyingly, the fob only seemed to work like 1/10 of the time. Dealer replaced some sensors, swapped things around, did all sorts of stuff... never worked quite right. My car has never _not_ opened. It responds immediately every single time. I stick my hand in and it's unlocked before I can pull the handle. I've not had to think about unlocking my doors in more than half a decade to the point where if I do stick my hand in and it doesn't open, my immediate thoughts are "do I actually have the key? is the car's battery flat?". Replaced my wife's vehicle with the same brand as mine, works flawlessly and consistently now.
