how to open 1997 to 2000 camry remote?

A friend of mine has a 98 Toyota Camry and called to ask me how she is supposed to open the remote to change the battery. She said it's a 1-button remote. She was told to pry it open (makes sense) but she has tried and tried and can't seem to pry it open. She said the dealer said that remote came with 1997 to 2000 Camry models. Any ideas on a good way to open those? Her battery is super dead and she really wants to get the new battery installed. Thanks much! This is the picture of it:

I have never seen that remote in person.  But if there are no visible screws, they do just pry apart.

that's what I was thinking. Every remote I've owned just pried open. I'm starting to think she is just scared she is going to break it. Thanks for the help.

she finally got it. I don't her to act like a drunk guy and just do it! LOL! She did, and she did!
