AUTO PULSE TPU Key Cover - 2 Button Car Key Protector for Duster, Lodgy, Logan, Verito (Black with Gold Edge)

Got this for my dad's duster key. Thought this would be hard plastic but is thick plastic which is ok.Problem is it comes in 2 parts.The main cover is ok and has slots for the back panel to sit into. The slimsy back panel though does not have slots.So it creates a bulge like a bubble and you move it around but never achieve a snapped fit.Main intent for getting it was to avoid main key button wear. The covering on this should take most of the brunt and hence works.OK if you don't pay attention to the back much and just use it.Another issue was the box it came in was drenched in motor oil. The key plastic was sealed and hence wiping the cover in tissue helped. But was a odd unboxing.
