We got a Mahindra XUV Flip Key for repair. Its spring was damaged. When we opened the key, we found that it has different spring system than what we normally get in other Flip Keys. Both the legs of spring are toward inside of spring (normally in other keys, one leg is toward inside and one toward outside). Moreover the direction of spring coil is opposite to what you get in other Flip Keys. This change is due to entirely different spring mechanism what we normally get in other Flip Keys.
