There is no key chip in the 2005 Ford Escape Hybrid. Despite appearances, that feature was not activated in the vehicle's software. If you need an extra key, a plain $1.50 copy will work. Do not pay the $100 or so for a programmed chip key copy.

There was a great deal of discussion about this on another forum. Ford finally conceded that the chip key feature is not activated on the '05 model. It is expcted to be activated on the '06. There are no plans to reprogram the '05s to make the chip key functional.
