It’s easy to think that the only reason you’d ever replace your keys is when you lose them. That’s why we hang on to our car keys tightly. With that, it’s easy to assume that you won’t ever lose your keys because you’re so careful with them. 

However, lost keys aren’t the only reason why you need to replace them. There are more reasons that you probably haven’t thought of, and that’s what we’re going to discuss in this post. 

  1. Damaged Key

Car keys don’t have to be broken for you to declare it as “damaged.” Keys that have been bent or worn out may already affect the pattern and grooves they fit with the lock of your vehicle. If that’s the case, a replacement is a must. Also, poor handling and maintenance, along with prolonged usage, may interfere with the pattern and grooves on the key and affect its performance. 

  1. Damaged Locking System

One of the reasons your car keys may have stopped working is because of the locking system. If you have the vehicle for some time now, it’s likely the system has worn out. With that, the system will no longer respond to your car keys. The only solution to this is to have your keys replaced. 

  1. Duplicate Key

Is the key you’re using for your car only a duplicate? If it is, then it may be a reason why it’s not working. In some cases, duplicates can prove unreliable. That is why you need to make sure you only work with a reliable company if you encounter problems with your car keys. 

  1. Damaged Key Fob

For vehicle owners who are using a keyless entry remote and it suddenly stops working, there could be damage to the transmitter, receiver, or internal electronics. Simply dropping your key fob can damage it, or having it exposed to excessive heat can cause damage to it, which is why you need to be extra careful with your key fob. 

  1. Ignition Cylinder Issues

The parts of your vehicle all work together. If there’s a failure in one component of your vehicle, it could produce a domino effect. For example, when there’s an issue with your ignition cylinder, it can cause your car keys to stop working. Also, the keyhole may be jammed by debris and other elements, therefore, creating problems with your car keys. 

  1. Drained Key Fob Battery

For your vehicle key fob to work, the battery must be fully charged. If the battery is drained, the keys won’t be able to communicate to the transponder chips in the fob and car locking system. Therefore, your car keys will not work. 

  1. Faulty Door Handles

Do you own an old vehicle model where you need to unlock the door manually with your key? In this case, faulty door handles call for a key replacement. Remember, your car door locks work hand-in-hand with your car keys; therefore, if the door handles aren’t working properly, the car keys won’t work also. 


Now that you know some of the reasons you will need to replace your car keys, it’s essential you only trust a reliable company to do that for you. Doing so will help ensure you won’t encounter any issues in the future.
