For the BlackBerry eKEY to open iBoxes, you will need a small Bluetooth to Infrared converter. The converter looks like the key fob you use to lock and unlock your car remotely
How does the eKEY Fob Work?
After entering your PIN in your BlackBerry, you can put your BlackBerry away and then use the fob to open the iBox.
When you point the fob at an iBox, it converts your BlackBerry's Bluetooth signal to Infrared, which is needed to communicate with the iBox.
The converter is very easy to set up, much like a Bluetooth headset.
It features inexpensive, user-replaceable AAA batteries.
eKEY Fobs can be purchased directly from GE Security using this form for $49.95 plus tax and shipping. Many Boards and MLSs carry them as well.
