39. Keep Your Keyring Light!
Here’s a little heads-up for you: having lots of keys or fancy keychains might hurt your car’s ignition switch. This could make it harder for your car to start smoothly over time. Experts say it’s best to keep only about three keys or keychains on your keyring.
But if you start noticing your key feeling stuck or your car having trouble starting, it’s important to take it to the dealer right away. If you ignore it, fixing the problem could end up being expensive.
