MegaIf your car still starts with a key, and it's attached to a keychain covered in other keys, charms and accessories, you may want to lighten the load.That seemingly harmless collection of trinkets could put unnecessary stress on your car's ignition over time, potentially leading to premature wear and an expensive headache down the road.According to a recent report from SlashGear, a heavy keychain can pull downward on the ignition while you're driving. That constant weight, combined with the movement and bumps that come with the roads, can put additional strain on the ignition components and cause them to wear out sooner than they otherwise might.The problem may not become obvious right away. But as the ignition wears, you could eventually find that your car doesn't start properly when you turn the key.MegaWhile there's no exact weight limit for one's keychain as ignition systems vary car to car, keeping the number of accessories to a minimum is always recommended.Most cars being manufactured today use a push-button start, per Motor Biscuit, but there are some still being made that use keys. And of course there are millions of older cars on the road that do not feature keyless technology.Read More From First for AutosCorvette Driver Blocks SUV From Entering Traffic, Sparks Viral Debate Over Who Was WrongPresident Trump Scraps Off-Road Limit on 'Red Dye' Diesel as Drivers Battle Soaring PricesCorvette Driver's Passenger Narrowly Escapes Burning Vehicle During Test Run Gone WrongThis story One Mistake Drivers Make That Could Be Unknowingly Ruining Their Car's Ignition first appeared on First for Autos.
