Anyone know of a smart key that auto unlocks?
Someone posted on another forum that "some" cars have a smart key that automatically unlocks the car as you walk up to it. The only evidence he cited was from Wikipedia:
http://en.wikipedia.org/wiki/Remote_keyless_system
Not too many actual sources in this article. Anyone know of a car that actually has this feature?
Thx in advance.
Method 1 — Once the keyholder is in the car's "bubble" (the required distance from the vehicle for the key to be recognized) the car will automatically unlock the driver's door.
Method 2 — Once inside the car's "bubble" the car doesn't unlock the door unless the keyholder touches one of the sensors located behind the door handles. As others attempt to get in, the system senses that the driver is within the "bubble" and as they touch the sensors behind their door handles, the car will unlock their door.

Infra, in Method 2, the car unlocks when the driver touches the door handle. This is how most cars that I know of handle it (including my IS). In Method 1, the car would unlock just when the driver got near - they don't have to touch the door handle.
I'm curious about this as well. Based on my experience with my IS, I'd prefer Method 1 for two reasons:
-Sometimes I try and open the door too quickly, before the system has unlocked the car
-When traveling with others, they often try and open the door before I've touched the door handle.
But I haven't thought too deeply about the downsides. I'm sure there's some that push car makers towards making Method 2 the standard.

I don't think it exists, except maybe in some ultra lux car.

I'm not looking for cars with SmartKeys. I'm looking for a car that automatically unlocks the door without touching the door handle as you approach the car. Yes, I could check specs, but it would kind of be a random search, not knowing any car that has this feature.

Almost. Your hand has to be near the sensor on the inside of the door handle. I don't like this implementation because it tends to get fussy with gloves. I prefer the implementation where teh door unlocks when you pull the door handle.

I've had my IS for 6 years--I have to physically touch the back of the handle to unlock, but do not have to pull. I've had 2nd and 3rd Gen RX, and 5 Gen ES loaners--same thing--you have to touch the back of the handle, or now the dimples on top and bottom. Your GS might be different.

it doesnt exist because it would be unsafe - not because it is not possible... the sensors you have in your 2IS can do that, but again, it would be safety/security issue.

There are some aftermarket systems that actually do function like this. There was a thread about it in the SC300/SC400 forums a while ago. Here's the video from that thread.

It wasn't really considered a "smart key" but I know on my friend's 1993 Corvette the doors would unlock as you approached and then lock as you walked away.
Kind of cool, but if you were outside near your car with the fob in your pocket, say, at home, it would continually unlock and relock depending on your proximity.

I have #1 option in my '13 BMW 335i. I just walk up to the car, and about couple feet away I hear the doors unlock. I'm sure any new BMW with CA (comfort access) feature has it. Not sure of other luxury brands, but if BMW has it - other luxury brands probably have it too.
