Will we ever have 'real' comfort access?

About a month into my '14 328i wagon and loving it. First vehicle I've owned with push button start and 'comfort access'.

I think these features are great and I got used to them quicker than I thought I would. However, I'm still stuck with a rather large key FOB in my pocket.

I was thinking how great it would be if they could make the key FOB the same size as a credit card so it can simply be put in my wallet, just like a drivers licence.

Perhaps some techies on the forum might have insight as to why the BMW FOB is so large, and if you think there will ever come a day for credit card size FOB's?

Battery. You need a battery to power the electronics in the key FOB that deal with remote control of the car through radio waves. With a credit card "badge" type system you need to contact the card with the receiver. I suppose that one day miniaturization will make what you say possible, at an affordable cost.

There is a lot of 'dead' space in the BMW key I've noticed as well. Coming from an Infiniti with basically the same access features, the Infiniti key is much smaller, probably about 50% smaller in total volume in my estimation.

bt1330 makes a good point about battery, in that you'll generally never see a "credit card" sized key; plus I doubt you ever will due to the fact that we do have a hard-cut key in the FOB as well in case of emergency.

Could it be smaller? Sure. I don't really mind it though.

You can shift the battery from the fob to the car with an RFID tag in a credit card looking thing. The two biggest problem I see is that you would still get a key. your current FOB has a key in it. so now when you have a credit card type "fob" you still have a key to carry around. Because of that I think it will be unlikely that companies will want to switch any time soon. They will most likely get more complaints about having to carry two things around rather than one. The whole reason most companies went with a key in the FOB was so you only needed to carry around one thing, going to two defeats that purpose.

Another thing to think about : with the amount of news regarding cyber crime and credit cards I have a feeling people are less likely to want to have their key be a "credit card". Just the shape can be a massive psychological factor.

(First off: It's a fob not a FOB.)

BMW made the fobs significantly larger for the F30, compared to those for the E90, which in turn were larger than the combination key/remote for the E46. It's nothing more than a "bigger is better" perception of status thing. I am not sure how current versions compare but not long ago, you could differentiate the fobs for a 3/5/7 at a glance by sheer size and finish quality. Silly.

The remote doesn't need to be much larger than a key blade, plus the space to accommodate a few comfortably-sized buttons and a battery. Giant fobs are only for style.

I don't mind carrying a reasonably-sized set of keys, separate from my wallet. If I had a credit-card-sized car key, I would end up carrying it in my wallet--and then I'd be seriously annoyed if my wallet was mislaid or stolen.

I can't speak for the f30 key, but most CA keys I've seen also usually maintains a physical cut and coded key for accessing certain things.

However, yes, there's a lot of room to make it more reasonable in shape and size. The battery argument is true compared to a credit card, but the battery is NOT that big. There's also opportunities like my 07 VW touareg, which has comfort access/push button start but can also be manually started with the key and recharges the fob while it's running.

Reminds me of a funny conversation I had going through airport security. I was picking up my backpack off the x-ray belt when I had this conversation with one of the guards:

Him: "Mini?"
Me: "Huh?"
Him: "I had a bet with my friend there about the type of key in your bag."
Me: laughing, "Close, it's a BMW"

Now that I think about it, somebody more privacy-oriented would probably sue or complain if they had that same chat. Lucky for them they got me.

Nail on the head here. I carry my E60 fob and my wifes extra F30 fob on the same ring. They both are unmistakenly BMW, but the F30 fob looks and feels newer. Agreed; silly. but its mass marketing in essence.

With that said, carrying 2 BMW fobs is a pain but my wife has a hell of a knack for misplacing her keys, so its not by choice.

Comfort FOB

Size does matter - no doubt the technology exists to make them sub-miniature! ... but, too small and they'll be too easy to lose. I suspect, as (cellular) technology expands there could be one device to do it all. "My BMW Remote" on IOS and Android does some of it now.

Or, taken to the next level, in the future, primary drivers might be given the opportunity to have an implant done at the BMW Service Center ... your turn

This card can communicate with your phone via bluetooth and change it's behavior when it gets separated from your phone..and it fits in your wallet. We could have key FOBs right now that fit in your wallet. A car mfg just needs to decide they want to do it.

As someone pointed out above it is likely the F30 key grew for status reasons. Look at keys from other mfgs they're huge, so BMW key fob should be huge as well. Thank you market research group.

Mein Auto: 2013 335i & X3 3.5
Have both, a 2013 X3 and just picked up my 335i couple weeks ago...X3 FOB is much larger but now that I have my 335 her key resides in the kitchen and not my pocket. I do not keep my FOB with my other keys because I don't like them jingling when I have to put the FOB in...which is my only complaint....not the size but why do I need to plug my FOB in my 335 but not the X3? Guess that's another post somewhere else. Size of the FOB is fine. Do not want one to fit in my wallet because I do not carry a wallet...

Oh, c'mon! There's plenty of Euro dwellers here and NOBODY remembers Renault Laguna with credit card key from 1998? Really? RFID for door opening (yes, plus the button for control freaks) and ATM slot for start?



BMW lost THAT race, then I guess they decided that, since they cannot lead, they might as well invent a new race - the one with who has the largest one

I dont like how you cannot start the vehicle from outside using the fob, which many competitors like cadillac include in their base lines years ago

I wouldn't want to be getting something out of the trunk and have someone jump into my car, start it up and drive off. I, for one, am glad it won't start if the fob is not in the car.

There's metal (key) in the fob, so I guess they would have a right to size it up (no pun).

My BRZ fob was probably less then half the size... it had comfort access, but it was made of very cheap hollow plastic and it banged noisely against else in my pocket.

Well, Germans do as Germans do. There is no accounting.

However.....come closer.....thought activated access implants are just around the corner!

Imagine....videophone, Internet, and vehicle control anytime everywhere simply by having it on your mind! Oh, and NSA identifier w/vital signs.

I like the Infiniti FOB much better over the BMW, I also notice that my trunk opens sometimes depending on what I'm doing, if the FOB is my pocket...

I just wish the trunk would open when I wave my foot under the rear bumper, I have gotten it to work twice out of the ten times I have tried it.

Gosh-a-mighty! Don't you know you need a reflective surface?

See, you need Wing Tips or at least polished leather loafers. Note: Polished. Yes. Those pesky 40khz waves gotta bounce offa something!

If you're comitted to sneaks or flip-flops, it can be an issue. I recommend affixing a mirror to the foot of your choice, looking upward.

Caution! Can result in arrest if not carefully used!

Mine works all the time (no matter what type of shoes).

Just follow the directions and kick under the back license and let you foot swing back out. Don't move your foot left/right.
