How Transponder Keys Work and Why They’re Essential for Vehicle Security
Modern vehicles are equipped with more than just mechanical locks—they rely on encrypted electronic chips embedded inside transponder keys to prevent unauthorized access and theft. These keys contain a tiny radio frequency identification (RFID) chip that communicates with your vehicle’s immobilizer system when you insert the key into the ignition or bring it close to a push-to-start sensor. If the car’s computer doesn’t detect a valid coded signal from the key, the engine won’t start.
This added layer of security makes transponder keys, chip keys, and smart keys highly effective—but also harder to replace without the right tools and training. That’s where our certified Phoenix locksmiths come in. At Affordable Security, we use state-of-the-art diagnostic equipment to read, program, and duplicate vehicle keys for almost every make and model on the road today, including those with advanced keyless systems.
