What is the difference between a transponder, remote control and key blade?

If you want to replace or repair your car key, you will come across terms such as transponder, remote control and key blade. But what exactly do these parts mean? In this blog, we'll explain the difference and help you determine what you need.

1. The transponder - needed to be able to start.
A transponder is a small chip located in the key housing. This chip communicates with your car's immobilizer system. If your car does not recognize the chip, you cannot start the vehicle. The transponder usually does not need to be programmed if you transfer it from your old key.

2. The remote control - for opening and closing
The remote control is the electronic part that allows you to open or close your car at the touch of a button. This part usually includes the buttons and a battery. Is your remote not working properly? If so, it could be due to a dead battery or worn buttons.

3. The key blade - the metal key part.
The key blade is the physical, metal part of your key that you insert into the ignition or door. Some models have a collapsible key blade. There are many different shapes and notches, so good comparison is important.
