Call around to locksmiths. The more sophisticated ones seem to carry these things. I believe they also own the programming tool to make the new fob work with your car.
Mine's a 92- 93- bought used so some part say one year some another, Camry 4cyl 5speed with 350,000+miles goes over 400miles on less than half tank of gas, until lately.
My son drives my first camry; a 97 with 243,000 miles. Original engine and transmission. Change the oil regularly is my best advice. My daughter has a solara 02 w/ 75k, and my wife drives an 08 camry w/ 32k. We believe!
