Customer reviews:
Actually about to ask for a refund. This locking gas gap actually kept making my Check Engine keep coming on. Sense I have takenivh 
 Does not lock 
 Would not fit right. 
 The gas cap does not fit tight enough and causes my light to come on in my vehicle. When you put the cap on and lock and drive you can smell gas fumes seeping out of the area because it does not seal tight enough. 
 Cheap kept leaking vapors leading to check engine light coming on 
 HAD IT ON FOR TWO-THREE DAYS...CHECK ENGINE LIGHT CAME ON CAP DOES NOT LOCK TIGHT CAUSING AIR LEAK INTO TANK. HAD TO TAKE IT OFF AND INSTALL ORIGIONAL CAP 
 After a month and a half it no longer works. My "Gas Cap" light now comes on. I would not recommend buying this. 
 not exact fit. 
 Did not fit 
 key broke after 1 month, locking is real touchy but once it settles down it works. 
 well it seemed to lock just fine and fit just fine but...

after driving with it for a few weeks every now and then i would get a check engine light on.....

so i googled that and found that the gas cap could be leaking so i put the old one back on and voila check engine light is gone......
