Toyota Repair: 1997 Rav4 key fob programming, keyless entry systems, key fob programming

Question
Just bought a 97 Rav4 and was given a remote that does not work.
Can I reprogram it easily?

Answer
First try replacing the battery and see if it helps, if not you can get back to me, toyota used a few different keyless entry systems and how to reprogram depends on which system is installed, the best way for me to help is if you can take a digital photo of the remote and email it to me, at tedrttr@yahoo.com and I may be able to show you how to program the remote.
