Why is There a Key in My Key Fob?

If you have a newer car, you have likely noticed that your key fob comes with a small key blade tucked inside. But why is this key there, and what is its purpose? In this blog post, we will explore the answer to this question.

What is a Key Fob?

Firstly, let’s explain what a key fob is. A key fob is a small, electronic device that is used to lock, unlock, and start your car without having to insert a physical key into the lock or ignition. They have been around for a few decades, but have become more popular in recent years with the growth of electronic keyless entry systems.

Why is There a Key in the Key Fob?

The small key blade that comes with the key fob is known as a “valet key.” This key is intended to be used in case the battery in the key fob dies, or the electronic system malfunctions and you are unable to unlock or start your car. The valet key will still allow you to unlock your doors and start your ignition manually.

Additionally, the valet key is helpful when you need to give your car to someone else to drive, but don’t want to give them full access to your key fob. For example, if you need to give your car to a mechanic or valet, you can simply remove the valet key and give it to them instead of giving them full access to your key fob, which may have other features such as a panic button or trunk release.

How to Use the Valet Key

To use the valet key, you’ll need to physically insert it into the lock on your car door or ignition. The valet key is usually concealed inside the key fob itself, so you’ll need to press a button or slide a switch to access it.

Once the key is out and ready to use, insert it into the lock just like you would a regular key. Turn the key to unlock your door or start your engine, and then remove the key from the lock. Be aware that the valet key may not have all the functions of the key fob, so you may need to manually lock and unlock your doors.


While the small key blade in your key fob may seem insignificant, it actually serves an important purpose as a valet key. By providing a backup method of unlocking and starting your car, it can give you peace of mind knowing that you won’t be stranded in the event of a key fob malfunction. So next time you see that small key blade, remember that it’s there to help you when you need it most.
