Ignition key of most cars looks the more worn out than other lock keys. This is due to the fact that is acts like master key and help to unlock the entryway door of the car, open the bonnet and trunk, and also work as the ignition key. 1 key serving multiple locks is prone to be abused and will age quicker. Replace such key so that you are not stranded at mid-night with a key that is left with zero traction and no functionality and every lock is unresponsive to the smoothed-out key.
