The Transponder Key: What Is It, and How Does it Work?

You may have heard the term “Transponder Key” before. You might not know what it is, but you’ve probably seen them on cars and figured out that they are some sort of key. The Transponder Key is a key fob that provides remote access to your car. It’s also called an RFID (Radio Frequency Identification) device, and it works by being read remotely from up to 50 feet away. This means that you can use the Transponder Key for entry, exit and trunk release on most vehicles without having to take the key out of your pocket or bag.

How Transponder Keys in Cars work?

A key with a transponder chip in it doesn’t just work to start the car, but also to make sure that your car and your key are legitimate by matching the authenticity of the key with the vehicle before starting it.

In order to work, the key needs a transponder chip in it (which is pretty much just an RFID antenna), as well as a computer system on the car that recognizes its presence. The keys need to be programmed with all the information about your vehicle, so they can communicate properly and do their job without any problems. This means putting in all of your VIN’s, serial numbers and other important info into both systems before you start driving around town. Once everything’s set up correctly, your Transponder Key will never need batteries again because it uses power when it gets close enough to the onboard computer—the same way most wireless garage door openers work. The only issue that might come is from the distance the Transponder Keys do not respond.

Benefits of a Transponder Key

The benefits of a Transponder Key in cars are many if you choose to install one from a locksmith Toronto. You don’t have to fumble for your keys when you approach the car and can quickly get in without worrying about locking yourself out of the vehicle. The fob also prevents key scratches by allowing access via a button, which means that it is safe from being left behind in a pocket or bag. If anything happens to your Transponder Key, it can be replaced easily, and you won’t need to worry about potential damages.

Disadvantages of a Transponder Key

However, the key does have some disadvantages too. One of them is that they are expensive in comparison with traditional keys; often costing $50 or more for a single vehicle purchase price (not including labor). Another disadvantage may come from having an unshielded fob with a powerful transmitter; this is because it may unintentionally cause interference to other electronics in the area, such as garage door openers and even some security systems.
