People with keyless entry may ignore this post. Rest of the folks who has the ordinary curved key, and thinking to get the leather cover from aliexpress/ebay, may want to look at this before ordering.
1) Quality of the cover is acceptable, although it is not genuine leather. For Rs 450, I expected genuine leather.
2) It makes the key really bulky, and adds to the bulge in the pocket.
3) It is not a proper fit. If you look at the pic below, you can see that the curves do not match, and hence the button for flipping the key does not match with the hole.
4) There is no way you can "attach" the cover to the key. So the key keeps slipping out.
You may avoid spending on this cover.
