It was almost exactly as the original and functions perfectly couldn’t be happier. This fob worked surprisingly. Bien, it is the shelter cover a worn fob as long as the inside parts of the original fob are working. You just open the original and place it inside very easy. This is a much better option than paying over 80 bucks to replace the original. It does not do anything by itself. I bought this product because the ring attachment broke on the key fob for my 2004 ford taurus. This was an easy, install and nearly identical to the oem part note this product is just the plastic shell and not the actual electronic remote. On my o2 jaguar s, types original remote, the shell was fine, but the lettering was worn off on the rubber buttons. This new rubber insert fit perfectly in the original jaguar remote.
