Keychains can be fun to collect as we travel or receive as gifts, however, adding them to your car keys could ultimately hurt your vehicle.
You see, adding keychains to your car keys adds weight to your ignition and this can cause the tumblers in your ignition to wear out. It could even lead to an ignition switch failure.
So as cute as keychains can be to show our personalities, the best thing to do for your vehicle is to have its own key alone.
This way, you can relieve yourself of the worry of possibly getting stranded due to an issue with your ignition.
