Transponder, Remote, or Smart Key? Car Key Replacement Explained

There are available options when you need key replacement services; the locksmith could suggest transponder, remote, or smart keys. However, knowing the differences between these keys will make a great difference in your experience at a locksmith shop. 

In this article, you'll learn the key types and their differences. Let's get started!

What is a Transponder Key?

A transponder key is one of the most popular car keys available. They have a built-in microchip emitting signals to communicate with your car.  This signal should be in sync with the one stored in the vehicle's computer before it can start. In case you lose or break your transponder key, you need replacement services.

Security boost is one of the advantages of the transponder keys. It is almost impossible for a person to duplicate the key or have access to the exact code.

But if you cannot find your transponder key, visit a locksmith shop.

What is a Remote Key?

A key fob, also called a keyless entry remote and a remote key, is a device that is used to remotely open doors. Even though it helps you open your car easily, it has nothing to do with the start of the engine.  

But the buttons of the remote keys can open, lock, or unlock your trunk. Some remote keys can also start the engine only when coupled with a transponder chip inside the key.

If your remote key gets broken or lost, don't panic. GreenPro Locksmith has the tools and knowledge required to help you out. We can grant you access to the car again by simply repairing or replacing the battery of the remote key in case it is malfunctioning.

What is a Smart Key?

A smart key is among the advanced keyless entry systems. With it, you no longer have to insert a physical key in the ignition. Instead, all you need is to press a button to start or have access to your car.

Smart keys offer convenience. They are very safe and easy to operate although they appear to be more expensive to replace compared to regular keys.  

In case you lose your smart key, you will need a professional locksmith who can reprogram the vehicle's computer to work with the new smart key.
