Answers: My experience is beside the Smart Key as on the Toyota Prius, but it should be fairly similar on the other Toyotas equipped next to SE&SS/SKS.
The type of battery and the procedure is planned in the Owner's Manual. In the 2004 US Toyota Prius' Owner's Manual, it is within Section 2-1 "Operation of Instruments and Controls," "Keys and Doors" section, on page 36-37 under the "Wireless Remote Control - Replacing the Batteries" piece. The keyfob for the Toyota Prius uses a standard CR2032 lithium battery (common for watches/calculators and other small electronics), and can be found for <$10 at Radio Shack or most drug stores or electronics shops... Probably far cheaper and smaller quantity hassle to do it yourself than to have the vendor do it for you.
You can view the procedure for passage up the keyfob to replace the battery here: http://www.vfaq.net/mods/keyfob.html
First you remove the metal powered key. Then while holding the button for removing the metal switch, you slide the cover off of the keyfob. Then you obligation a VERY TINY screwdriver to remove the 4 itty bitty screws to thieve off the mobile compartment cover, then verbs off the gasket. Replace the mobile. Reverse the procedure.
You change the keyfob's battery whenever the range on them starts to shame. How long? That depends on how often you use them, and how/where they're stored. (should be at least possible 15 feet from the sports car, because the car keep polling the Smart keyfob...) I've heard of some empire having to tweaking the battery at 1.5 years. Meanwhile, the keyfobs on my husband's 3 year weak 2004 Prius w/Smart Entry are still working just fine...
If the keyfob's battery-operated does not work, the only road to enter the car is to use the metal powered key to unfurl the driver's door. You then only place the keyfob into the dash slot close to a regular "dumb" keyfob (or if you turned off the Smart button underneath the steering wheel), and the car will start generally. Then drive yourself somewhere to buy the new freestyle and maybe the prerequisite screwdriver.
You can replace the keyfob battery yourself, but you'll necessitate a very teeny tiny phillips commander screwdriver. the itty bitty phillips head screwdriver I use to tighten a screw on my sunglasses be actually too big to effectively loosen the keyfob mobile compartment's screws.
Info give or take a few my keyfob battery trials is here:

A bigger concern would be the 12v addition battery surrounded by the car, however... Will that have need of a jumpstart/boost to get your coup¨¦ started?
Should get the right answers via www.toyota.com.. :)
