What Is A Transponder Key?

But what exactly are transponder keys? Read through this article to learn more. However, feel free to contact one of our expert locksmiths for all your transponder key-related issues.

What is a transponder key?

Transponder keys are designed with radio chips emitting low-frequency signals to communicate with the vehicle's ignition and security systems. Through the use of RFID (Radio Frequency Identification), the receiver can recognize the serial number and start the car only when the correct number is identified.

What a Transponder Car Key Does and How It Functions

The RFID microchip is an anti-theft unit that sends a signal to the immobilizer to start the car's ignition system. Only when the immobilizer reads out the corresponding digital serial number will it deactivate itself, allowing the engine to start. The car thief may get inside your vehicle, but he won't be able to start it without the correct key. To function, the key's programming must link with the code stored in the car's system.

When the correct key is inserted, the microchip within the key deactivates the immobilizer, and the car engine starts. Many people ask if they can reprogram the chip key independently, but we do not recommend doing so. It is better to ask a qualified car locksmith to do the programming for you.

How Secure Is the Transponder Key?

Transponder keys not only secure your vehicle more effectively than regular keys, but they also do so in a few different ways.

• When someone attempts to disengage the ignition system, it won't be achievable, even if they apply other tools or keys to start the engine.
• Any attempt to "hot-wire" the vehicle will be fruitless.
• The digital ID number coded into the key and the remote transceiver is extremely special. If the car's built-in immobilizer device doesn't recognize this personal ID, the car won't even turn on.

Advantages of Transponder Keys

Transponder keys have a bunch of functions that other car keys do not have. 

• They decrease the rate of vehicle theft and improve owners' security measures.
• The use of transponder keys makes it difficult to hotwire a car's engine and also makes it immune to vehicle theft with fake keys. The codes coming out of the chip are unique and almost impossible to duplicate, which minimizes the possibility of a criminal stealing them.
• The keys are the most difficult to duplicate without the original programming. If a thief can enter your vehicle, they’ll not be able to start it, as access is restricted by the individual code sent by an electronic chip.
• Modern key transponders offer a range of extra features, such as remote vehicle starting and multi-function push buttons.
