    exchange replacement as expected.
    update:replacement gas cap works for vehicle. the new set of keys are more complex than the first pair and look more like real key bitting and not a fish scaler. deducted two star for the hassle and time wasted.old review:I am pending an exchange for this and have not put it on my vehicle yet. Why? The key bitting or shape of the key is a joke. It has a simplistic repeating wave pattern that looks like it would be for demo or display purposes. It looks nothing like the photo. Hopefully not all they keys are made to look like this. I was surprised to see this stupid key on an actual product. It looks like a bump key or wafer jiggler than an actual key pattern.
