Why Is My Car Key Worn Out?

It is normal for car keys to become worn down over time. Think about what a car key goes through daily; they move in and out of locks and the ignition, causing keys to contact metal. You probably store keys in a bag or purse during the day, where they may knock against other items. Also, you might drop your keys frequently without even thinking about it, letting them crash against the hard ground. These various actions add up to a dull, worn-out car key over time. 

Of course, if you have a key fob, you don’t have to worry about this as much. However, fob keys can also become worn out over time and stop working. 

Is A Worn Out Car Key Bad?

A worn-out car key is bad because, over time, it may fail to start your car or can damage your ignition. It happens slowly, but keys will start to degrade and no longer be compatible with their locks or the ignition due to a dull thread. A few cuts and dings are nothing to worry about, but these small blows eventually add up to a dull, worn down key over the years. What was once a small scratch can turn into a valley, making your key no longer functional.

One day, unexpectedly, your trusty keys may no longer open the door or get stuck in the ignition. This could leave you stranded somewhere.

How To Prevent Car Keys From Wearing Out

With proper care and maintenance, you can slow down key wear and prevent it from becoming a problem. With the following steps, you can ensure your keys will last as long as your car.

1. Make Extra Copies Of Your Car Keys

Making extra copies of your car keys is a great idea for both regular car keys and key fobs. Once you have multiple copies of your car key, you can rotate them, decreasing the wear each key goes through. Once they start to look too worn down, you can always get another copy made.

Having a spare set is also great if the set you normally use stops working. It prevents you from getting stuck because you will have a backup key already made. 

2. Clean Your Keys Regularly 

Cleaning your car keys regularly also slows down wear. Using any multisurface cleaning agent and cotton balls to scrub your key once a week prevents built-up grime. It also prevents any excess dirt on your key from transferring into the ignition or door locks. As a bonus, regularly cleaning your car keys prevent the spread of germs too.

3. Properly Store Your Car Keys

Improperly storing car keys can lead to damage for both regular keys and key fobs. 

For key fobs, you need to make sure to keep them away from extreme temperatures, especially heat. Electronics do not mix well with extreme heat. Storing your key fob in a spot that gets really hot or cold could lead to wear and prevent it from working. 

For regular keys, you need to make sure to store your key in a dry, well-ventilated area to prevent rust from developing. A key left in humid, wet conditions for too long has the potential to corrode and rust, thus wearing down the key.

4. Don’t Attach Extra Items To Your Keyring

Attaching items to your keyring may look nice, but extra weight can cause your key and ignition to wear down faster. Extra weight puts added pressure between the key threads and the ignition barrels. Added pressure leads to friction, which in turn causes wear. It is always best to key your key separate from any other items. 

5. Lubricate Your Car Keys And Locks

Lubricating your car keys and locks is a great way to prevent unnecessary friction between metals. A decrease in friction prolongs the life of your key. Make sure to use a graphite-based lubricant on metal. Other lubricants could attract dirt and dust, which will only cause more wear to your key.
