Hey Guys,
This is my first post on these forums since I just picked up my IS 250 AWD yesturday (1 day from the day i first test drove it). The credit card sized device is pretty much standard here in Canada. What it does is it sits in your pocket and as you approach the car, the lights under the mirrors automatically turn on. You then grab the door handle and the doors unlock. You sit in the car, press the start button, and the car turns on. You can also lock the door by pressing the a button that is on the front driver and passenger handles. You also have the ability to access the trunk the same way. You just press a button that is under the trunk door, and the trunk pops open. And yes, it does have a spare key built in. The device is much smaller than a credit card, it is more the size of those garage door openers that go on your keychain. Hope this helped.
