Review on Stant 17504Y Keyed Alike Locking by Dave Russell

Update: after the wait the gasket worked and now my check engine light rarely (yet, just rarely) comes on but the gasket is so tight that it is very difficult to open it. Improving my star rating from 1 to 3. I bought this cap to replace my existing cap which was intermittently coming loose and causing the check engine light to come on. Well this cover has the check engine light on all the time and now I need to replace that too. Not too happy with that. But hey, at least it locks.
