Assuming you don't lose your phone

I can see the demand for this. The Texas electronics firm Keyless Ride is introducing a new remote-control system which permits you to access your existing keyless-entry system with devices other than your fob: a Bluetooth-enabled cell phone, perhaps.

So if you lock your keys in the car, you just hop on the cell, dial up a code, and the door pops open.

(Or, if you're a cheap so-and-so like me, you have a spare key in another pocket.)
