Infared / Radio – Can a device unlock the car door, the initial start, open garage door, disarm the alarm, etc?

My friend is the girlfriend of a real estate agent and has a phone that uses infared to unlock lock boxes that store the keys of the house for sale. Is there an all-in, equipment a device that could provide, and / or software that I could charge my BlackBerry to do these other things – Lock / unlock the car door, the initial start, garage door open, on / off your house alarm, etc. I want to consolidate devices and remote controls. Any suggestions? In fact, I'd like to get rid in my pocket all together well. Perhaps the future thinking of using the same device to be encrypted driver's license, credit cards / debit cards insurance, membership cards, simply slide the device through a card reader and select for use on a touch screen ??????

and you realize what happens when you lose your BlackBerry while he did that.
