Super disappointed! I loved them at first because they are a great visual deterrent, hence the 3 stars. However, when I went to reinstall my mom's car, neither of her two keys pulled the spring-loaded pin back far enough for me to lock or unlock it. If this happened while the trunk was in their car, we were unlucky and stayed where we were if we had to evacuate due to a fire or other emergency. Aside from the lock sticking (which is a HUGE issue) the finish seems fine. I'm not sure if this is a silly spring loaded design flaw because if I stick my finger in I can move the pin slightly, so maybe that's how the key is designed. Either way, they're back.
