Here are a couple of plastic panel and clip removal tools with Toyota/Lexus part numbers. The top one is 00002-06001-01, the bottom one is 00002-06002-01.
What did they cost? I have been dreaming up ways to make them from household items. Got so work to do soon on my wife's rolla.
I don't recall what the cost was. A friend picked them up when he bought an XM kit for me to install in his LX470.
I picked up a removal tool similar to the one on the left at Harbor Freight for a couple of dollars. Works fine. I used it for the Fog Light Kit installation with no problem.
You can go to home depot and get a 99 cent plastic scraper or a caulking tool kit, which has the handy remover on one end.
I also bought the yellow tool kit (comes with 4 removal tools, all different shapes) for a few dollars from Harbor Freight. They work fine.
I have a set of ABS plastic trim tools like the ones posted above, but I find myself going to the cheapie metal one almost all the time. It's about $8 at Pep Boys. http://www.amazon.com/dp/product/B000CMDPCQ?tag=priuschatcom-20
That looks almost like the one that I got from Harbor Freight. The only difference is that the top of the tool is a wedge shape and not squared off like the Amazon one.
