Thank you for the two examples, which I hadn't considered.

Well, that sounds like someone trying to misuse a security(?) feature to

help compensate for forgetfulness. Useful, perhaps, but counterproductive

to the purpose of the system.

Security. What is security?

Best security makes it as easy as possible for the good guys and as hard

as possible for the bad guys. Trying to make it do more than that tends

to reduce its effectiveness.

Good security is not broadcasting your lock/unlock RF keys over such a

wide area that you can be sure that an RF-code-stealing-thief can grab

them, and also means not having the car point itself out to said thief

when he re-broadcasts the grabbed code(s) after you've left...

Once you try to make the key too fancy and far-reaching, the less secure

it is.

You know, your house key undoubtedly opens locks on other houses. And,

similarly, others' keys can open the locks on your house! Once it becomes

too easy to try (broadcast) a key in a large number of locks

simultaneously, security tends to be reduced, not enhanced.

So consider over how broad an area you wish to always broadcast your key!

(And over how broad an area you'd like others broadcasting theirs!)

My remote has no panic button, and I've never needed nor wanted nor thought

about one; I was thinking about remote keyless entry. Further, is there

one person left on earth does not, with varying success, tune out all

obnoxious car alarm noises? If I wanted to call attention to a bad

situation, I'm not sure how I'd do it (likely the Loud dog whistle on my

key ring), but having to rely upon a car alarm wailing would not make me

feel much/any better in a "panic" situation. You can carry a portable

noise-maker if this is a big concern, though I remain at a loss to know if

it's preferable to have a blaring noise 1' away, 50' away, or 100' away

while being attacked.

The less far-reaching the RF transmitter's effect, the less likely that

someone else's remote has unlocked your car without your knowledge, the

less likely your code's been grabbed (it's safe to assume the code can be

grabbed from even farther than your can can respond to it), the less likely

your car and its contents are not the way you left them or that there is

a bad guy hiding in the back seat awaiting your return.

Just because RF is invisible to you doesn't mean it's invisible to the

bad guys, to whom you're broadcasting an exact copy of your key every time

you push that button. (I believe Volvo's still using non-varying codes.)

So if you're that worried about the bad guys getting you(r car), the last

thing in the world you want is an extended transmitter range, and the

2nd-last thing in the world you want is for your car to say LOOK AT *ME*

every time the code is transmitted.

IMO, that's much worse than a login portal that reveals the difference

between a nonexistent account and an incorrect password, which is

considered bad security.

So what some see as an Acura feature (see

http://brickboard.com/READER/?file=10050855&referer=AWD ), others see as

an Acura security lapse, and still others see as easier pickings. We all

have our own viewpoints...

Roll on,
