I really like Toyota’s Smart Key, or Smart Key in general.
It’s so convenient! No need to put out the key in your pocket to:
1. Unlock the car – Touch the driver’s door handle
2. Lock the car – Press the button on the driver’s door handle
3. Start the car – Press the Start/Stop button
4. Open the trunk – Press the trunk button

Anyone with your smart key can do any or all the four things listed on top. Smart key works within four feet, so if you’re standing with someone within four feet, and you have the smart key, he can also do all those things.
