Stant 10506 Locking Fuel Cap

I wish they had identified the top or bottom of the key slot or they could have used a double sided key, since the key isn't guided into the lock very well it's always a bit of a pain to figure out which end is up.

Another thing that would help, would be some kind of retainer, even if it didn't exactly match the original, at least some kind of lanyard attachment so I didn't have to worry about losing my new gas cap.

At least the fit and function are close to the original cap, just slightly loose.

with confidence...

I purchased locking gas caps for all the cars in my family (5). Due the the high cost of gas now, we have had neighbors who had gas stolen out of their cars. If a thief tries to steal from any of our cars, it would take more effort than its worth to get to ours. I would suggest buying these because they are a very good cap and a great value.

I bought this to have some ease of mind about not losing fuel to gas thievs or vandals. It works just fine and lock great on my car (1998 Chevy Blazer), but it allowed gas fumes to leak out of the tank which reduced the gas efficiency of my car. With gas prices steadly rising, I would not recomended this to consumers.

And if you live in an area when an emmissions test is required to obtain an inspection sticker, the leaking fumes will cause your car to fail.
