Review on STAUBER Lexus Key Shell Replacement/NO Locksmith Required Using Your Old Key And Chip! Car Electronics & Accessories by David Urbanski

It's fantastic. They are a bit bulky but durable which I am very happy to sacrifice a little weight for security compared to the OEM key fob. Installation was easy, but I modified mine a bit to still use the default key. I used a very small flathead screwdriver to punch a hole in the key and shape it to mark and guide the hole. I then used my drill with the correct size bit and then countersunk the screw with a larger bit to bevel the top of the hole. After some alignment work, the screw snapped into place and sealed well. I then used all three supplied washers on the back of the key, installed the second plate with a star tension pattern and wow. Great, now I don't have to watch the key anymore. Love it!
