- The PKE system is in addition to the normal key/lock operation.
- Now if you lock your keys in and run the battery dead, you are in
- trouble.

- PKE is "passive" in the sense that you don't have to push a button
- to lock/unlock the car. But the remote (the fob) contains a battery
- and transmits a signal indepently of whether or not it is in range of
- the car. The fob goes to sleep when there is no motion in order to
- conserve battery life.

- You don't really need to trust it, since you can always use the keys.
- And you need at least the ignition key to start the car.
-
- An interesting capability with a system like this is that each key fob
- can have a different ID code which can be used to determine which
- driver is using the car. Then the car can memorize personal preferences
- such as seat position and automatically recall the preferences
- for that driver when he/she opens the car.
