Hey guys,
so I am not new to the idea of using the keyfob to open the windows on a hot day, or close them when i forget to before taking out the key.

but Ive noticed that it doesnt always work. Most of the time, I cannot get the windows to roll down even if I hold the unlock button for a long time, multiple times, just doesnt work. And the same goes for rolling them up via the lock button (though it works more than rolling the windows down)

what am I doing wrong?

You need to point it towards the driver side door. There is a sensor on it

even when i point it right at the sensor, it doesnt work all the time... i have to usually press and hold 3 or 4 times ... could this be a battery issue or could this be a problem with the sensor or programming?

you gotta be pretty close... less than 6 feet from the drivers door. and just when you want to let the button go the windows roll down!

BenTrovato

6 feet is about right. Make sure the bottom of the key is pointing towards the sensor on the door. It doesn't work well when you are doing it from the front of the car. Directly perpendicular to the door works best and you can rotate yourself all the way to the back end of the car as long as you are in the line of sight of the sensor.

I always just walk up to my door to do it and it works first time, every time.

Mine stopped working completely. I'm assuming it's a setting.

joshg1001

yeah it doesnt really matter how close I am to the car, but I will try pointing it towards the door handle today. It just seems erratic at this point

I didn't even realize this feature existed

Tried both our cars (08 E and 09 C) and it works on both. Did not test distance, but it worked in the garage, opening and closing.

stand 2-3 feet away, point keyfob to the sensor on driver's side (I don't think passenger's side works)

I noticed that it doesn't work if you are too close to it...

rb23lb

EXACTLY! some times it works, but only for a second and the windows stop 1 second after starting to close...

i took my car in for this today... hope they can fix this annoying issue... mine hasnt worked properly for over a year

alexlev

Maybe that's what I am doing wrong?

I found out about the feature about a week after getting the car . . Tested it out but it only worked once out of every 4 attempts. I guess it might be because I hold the key almost an inch away from the sensor.

white_glass_top

didnt know that it closed that way also, just thought it was only for opening, will have to try it out tonight.

I thought that cannot be true if you just point accurately to the IR receiver (the beam is narrow and you have to be accurate when pointing from close to the door).

But I tried it with my 221 and I had to more a couple of inches away from the sensor before it started working. If I touch the sensor with the key, it does not work. I wonder is it because of the IR signal being too strong from that distance, saturating the receiver?

An interesting observation.

Okay I'm lost...what the hell are you guys talking about. I haven't heard of this feature

Sportstick

I hadn't either.....

Just stand by your driver's door and press the UNLOCK portion of your key fob. JUST HOLD IT.....and after a few extra seconds, watch all the windows and sunroof open. LOCK does the same thing in reverse. You will figure out how far away your car can receive this signal, but the target is that little square on the driver door handle.

I find it basically useless, You are so close you might as well get in and open everything up. Now if it worked from 20 or so feet away from all sides it would be usefull to me.

Sanjuro Makabe

yup I had the same problem, thought mine was faulty, then realize I was standing WAY too close to the sensor...same thing...1 inch is too close, ever since then it always worked, no fixes, nothing, just stand further lol

Sanjuro Makabe

yea the target is that sensor on the driver's side handle, but I do notice the range is pretty wide and far...its funny coz it doesn't always work if you point directly at it less than 1 inch away lol

useful on a hot day to are everything out. Last week when I posted this, it was constantly 100 degrees here and I have a black interior and exterior.

also useful when you forget to close a window. since you have to lock the door with the key anyways, might as well hold the lock button for a little longer to close it for you

jstaneff

I find it quite useful on those hot days here (temp about 80 F) when the car's been sitting in the sun and getting hot inside. Just walk up, unlock and open windows, then pop the trunk, take out an ice cold soda, and drink some while the car cools off.

We don't get 100 degree days very often, so that's not a problem.

This is a nice feature for cooling off the car without unnecessary use of the A.C. And it's nice to close up the car when you walk away. But I'd rather have tunnel mode. Oh well.

rb23lb

here is a good tip that is related...

If your sun roof stops doing the one touch close and needs to be reset by the dealer, I found that this also solves the problem of the key opening and closing of the windows as well

the sunroof reset and the key open/close reset are related and they both are fixed by the same reset, if that makes sense...

my key wasnt working to close open windows anymore, and my sun roof was jacked up too and not closing... they reset the software and they both started working basically...

joshg1001

every since i started pointing it directly at the door handle, it has worked every time

rb23lb

u definitely need to reprogram at the dealer under warranty... now that i have been reprogrammed, i can close the windws from 5 feet away while aiming at the side mirror basically, no joke... before i had to be very close and aim directly, and then it would only close intermittently and stop if i slightly moved my hand from aim...

Spec_Davis

i never knew i had this option. summer is over here so i do not intend of using it.
