Your car’s ignition key does more than start your vehicle—it’s essential for mobility and convenience. Yet, a common habit of attaching extra keys to it can have serious consequences, affecting safety, performance, and even your car’s lifespan.
The added weight and bulk from extra keys can damage the delicate internal parts of the ignition cylinder. Experts, including Jake McKenzie, content manager at autoaccessoriesgarage.com, point out that ignition cylinders aren’t built to carry heavy loads. When loaded with multiple keys, the constant movement from bumps, turns, and vibrations gradually wears down the intricate internal mechanisms.
Here’s why you should avoid hanging additional keys on your ignition key:
Faster Wear and Tear:
Turning the ignition key sets off a complex mechanical sequence. Extra keys increase stress and weight on the cylinder, accelerating wear and potentially leading to costly repairs or replacements
Ignition System Problems:
Modern ignition systems are finely calibrated for engine performance and fuel efficiency. Extra keys can disrupt this balance, causing misalignment or damage that may lead to starting issues or electrical malfunctions.
Higher Risk of Ignition Switch Failure:
The ignition switch isn’t meant to carry heavy keychains. Constant swinging can deteriorate internal components, making it harder to turn the key, start the car, or even causing full switch failure.
Security Concerns:
While combining keys may seem convenient, it can create security risks. Losing or having all your keys stolen gives easy access to your car—and potentially your home or office.
Greater Chance of Key Breakage:
Extra keys make the ignition key heavier and longer, increasing the likelihood it could snap inside the cylinder, which is both costly and time-consuming to fix.
Reduced Driving Comfort:
The weight and bulk can make handling the key awkward, and constant jostling may eventually harm interior components.
Warranty and Insurance Implications:
Some vehicle warranties or insurance policies have restrictions on modifications. Hanging extra keys could void coverage if ignition issues arise.
