Emissionwiz is correct, but, his information is for older Model Camrys.

The 2003 "factory-installed" radios in the Camry product line does not have an anti-theft feature, and, because of having no anti-theft feature, there is no reactivation code. If you have a dead battery, the only thing you will lose regarding the radio functions would be the radio stations that you programmed into the memory. The radio will function properly after a dead battery is replaced with no issues.

Disconnect your negative battery cable for about 10min. After you re-connect, the stereo should reset itself and start functioning. Best of luck!

SOURCE: How to....remove radio sepakers (rear) from a Toyota Echo??

It's really easy to remove the rear speakers. First, get in the trunk and find the 3 white anchors for the rear deck-they're near the rods for the trunk mechanism. Push them through the metal frame to free the deck. Next, you have to get in the back seat and remove the stop light from the deck. To do this, push in the pins on the locking mechanisms on either side of the light to free the back casing. Pull the pins out and the casing off. Next, undo the two bolts holding the stop light in place and pull it off-don't forget to undo the wiring harness. Next, find the three anchoring points for the back seat. Gently lift the two side ones free of their anchors. This gives you access underneath the deck. Free the deck and gently lift it over the seat. You'll have to jimmy it a little to get the locking clamps free--they're all along the back of the deck. Pull it free and you have access to the speakers. I believe the factory speakers are 5 1/4 inches
Try to use Toyota speaker adapter plugs so you don't need to cut wires and mess the electric system up. You can get them from Ebay or Amazon.
