How can you fix a worn down car key?

My car key has been giving me some trouble recently. I often have to give it a bit of a shake before it will turn on the ignition. Is there a way to fix a worn down car key?

Your car key, like many other components of your car, can get worn down and stop working as it should. While you can’t fix a worn down car key, you can get a replacement key.
Generally, a new car key costs anywhere from $50 to a few hundred dollars depending on the type of key your car uses and if you need to replace the entire fob or not. You can typically get a key replacement through a dealership or a locksmith. If necessary, you can also usually buy blank keys online for locksmiths or dealerships to cut, which can save you some money.
Additionally, you should avoid trying to fix the key as DIY repairs could cause significant damage to the locks or ignition, which will cost even more to repair.
