You have probably had that one terrifying experience of having locked your car keys inside your vehicle. It is, without a doubt, an unexpected and frustrating moment. Usually, it happens when you are on vacation, on your way to an important meeting, or running late. However, with a transponder key and increased car security, locking your keys in the car is impossible.
Unfortunately, nothing, including transponder keys, is infallible. Criminals have devised different ways of breaking into cars, including those equipped with transponder keys. So, ensuring these unique keys are working is necessary these days. But what else can you do if your transponder key suddenly stops working? First, let us overview what a transponder key is made of and why it is so important to have it always working.
What is a Car’s Transponder Key?
Transponder keys are standard on most cars manufactured in the last 20 years as part of the anti-theft security features. Since then, car manufacturers have adopted these keys as an industry standard. In addition, these special keys feature an RFID (Radio Frequency Identification) chip embedded in the head of the key, offering another degree of security to your vehicle’s ignition.
How Do a Transponder Key Work?
When a key is inserted into a car’s ignition with an immobilizer system, the automobile checks for an RFID chip in the key and programs it to the vehicle. The immobilizer system prevents the ignition from allowing the car to start if the vehicle does not recognize the key. No one can steal your car because the transponder key and the engine immobilizer operate as anti-theft devices. In addition, they are designed to work together, so if one fails, the other will.
What Makes a Transponder Key Safer?
Transponder keys increase vehicle security in two ways. First, they make ‘hot wiring’ or breaking the ignition lock useless, which helps deter and prevent car theft. The automobile will only start if the key’s microchip or exact serial number is not detected. A transponder key’s digital ID is unique compared to a standard ignition key with with a few basic cut combinations. Thus, it lowers the risk of someone else’s will use their key to start your car.

There’s a risk that your vehicle’s battery is dead if you bought it pre-owned or have had it for a long time.
