This video tutorial shows you some of the benefits of the SmartKey on the 2010 Toyota 4Runner. This key can be used as just like the standard version, using the remote controls to lock and unlock the car. This key also provides keyless entry; if you have the key in your possession and approach the car it will unlock the doors for you. You can also use this key to open and shut the rear window. The SmartKey brings a bit of innovation to the once standard remote control key.
