Comfort access for $1,000 does seem very expensive. I plan to get it anyway or I know I would regret it. It will likely be standard next year or the next. And I agree, a start/stop button without comfort access seems silly. I would prefer to just stick the key in and turn it.

My father as an 04 Lexus LS430 with smart key access. If any of you who are raving about the BMW start/stop without CA, maybe you need to look at other keyless system. The LS was one step close to true keyless; 06 GS comes standard and perfect it.

1. Put the key in your pocket.
2. Be within less than 12 inches of the car (touch the handle). The door lock opens.
3. Sit in the damn car and start the engine (push button). Your passenger can be holding the key if he/she wanted to.
3. Drive.

I believe that's what BMW with CA is trying to attain. Hence, without CA, it's simply a half-a$$ job. Proponents of "push buttons," you have a point about the messly extra step. Opponents of the push button "without" CA, you also have a valid point.

That's how Keyless Go works, no different........only it worked half the time as I stated above.

I don't think its all that difficult to push a button that unlocks the door and pull the handle to open it.

The only slight advantage of CA (to me) is the start/stop button deal.

I say slight because you need to have the key on you regardless. I don't personally just carry around a key, there is other crap on the keychain.

Therefore the keys are not in my pocket. So just like with the E500, I would have to get in the car, store the keys and then press the start/stop button.

I completely agree. It does have the emotional aspect. It is not all that useful, but again, it is one of the new things on the market and I like it.

I also agree that Comfort Access should be standard on the 5 and 7 series. Just add an extra $800 or so to the price of the base.

I am also tired of reading "it's an extra step". It takes less than a second to perform this 'extra step', but you get the "cool factor" with it.

Again, CA should be standard, but if BMW has a push-button start on some of their newer cars, then I want it!

Perhaps if BMW implanted a chip in your head or have an iris scan, would you be happier? In the case of a woman who carries her purse around all the time, smart access is convenience. Perhaps if automakers make a "key" slim enough (access card) so men and put it in their wallets, I guess enough I will be happy.

If comfort access is standard than I would live with it, if it is not than I wouldn't get it for sure because I have tested the GS and the salesman is holding on to the key and I didn't see the key until we were back at the dealer. Is a pretty weird feeling driving without a key, but I guess you will be used to it just like when keyless entry first come out on the market and you skip the step of turning the key to unlock the car.

As for the hurting engine part, let's just say you don't know your car well. It didn't exactly say on the manual but I figure that when a 2004 Pontiac Grand Am rental car have the start assist feature, shouldn't a car like E60 have it? So I try it on the demo and yup is there.

With all the problems BMW is having with their electronics, would you still want the comfort access the first year they introduce it?

If you like I made a little video on the Start up and stop of the E90... essentially the same as the New E60 start.

Knubblo,

I hope you didn't let a saleperson talk to you about DES and 128-bit. For the sake of this forum, I will try not to be too technical and my memory might be rough, so correct me if I'm wrong:

DES (data encrytion standard) uses 56 bit long keys. 3DES (triple DES) uses 112-bit long keys. DES has been proven crackable in a little over half an hour of brute-force exhaustive search.

128 bit is very secure. That's wehre AES (advance encrytion standard) comes in to replace DES back in 1998. I think AES can come in 128, 192, and 256 bit long keys. AES is the federal standard for secure network (electronic) communication. That's why website with (ssl or https) are 128 bit encryted. It's near impossible (in practical terms) to crack this encrytion.

Hence, if a car key is 128 bit and push button is DES, somebody is going BACKWARD. I do believe the car key is 128 bit encryt. That's just my cobb web memory with computer network and RSA Lab.

It's an MB, what do you expect . . . for it to work ALL the time? My father's LS430 works eveytime. My brother's S500 . . . he hasn't been bragging about it, but I'll ask him.
