How Your Keychain Affects Ignition

0

How many keys do you have on your keyring?  Add in any number of multi-tools, sports-themed keychains, maybe a small flashlight, picture of the kids and shopping reward cards and you end up with a decent bit of weight on your keyring.  Once you put your car key in the ignition, that’s quite a bit of weight hanging from the key.  That weight over time, plus the road bounce that comes with driving, can lead to wear of the tumblers and eventual ignition failure.  Take stock of what is on your keyring and “lighten up” a bit to spare yourself the unnecessary expense of replacing an ignition component.
