A transponder key, also called a chipped key, uses a microchip to send a signal to a vehicle that unlocks the doors. Many modern cars utilize this technology because it is more safe and secure than a traditional lock and key. Below is more information about how these devices work, why they are beneficial, and how a locksmith can help you if you lose the transponder.

How Do They Work?

The microchip is located inside the plastic head of the key. When the device is within range of the vehicle, you can press a button that emits a radio frequency. This sends a signal to a ringed antenna around the ignition cylinder. The computer inside the vehicle must receive and verify the serial number encoded in the microchip. When it does, the computer unlocks the doors, allowing you to open them.

What Are the Benefits?

Transponder keys enhance vehicle security. The serial number encoded in your device is unique to your car and provides a distinctive digital identification, making this the only key that can open the doors. If someone tries to hotwire the vehicle or break the ignition lock, the engine will not start because the antenna has not received the digital information it requires from the transponder. This means your car and belongings are much safer.

These keys are also easy to use, especially if your hands are full or you need to open the doors quickly. They are particularly helpful for people who have arthritis, as fumbling with individual keys and locks might be challenging. Additionally, many vehicles that use transponder keys also have push-to-start buttons. This makes turning the car on much easier, as you don't have to dig the key out of your pocket or purse.

How Can a Locksmith Help?

Unlike a traditional key, transponder models are designed to discourage easy duplication. While this makes it much harder for criminals to access your vehicle, a locksmith can still help you obtain a copy if you lose the key or it stops working. They utilize the same equipment as auto manufacturers and dealerships, allowing them to replicate and program new microchips. Plus, they can often do so at a lower cost than a dealership.
