What is a Transponder chip or rfid chip?

A transponder chip is an RFID radio transmitter that is hidden in the key. It talks to the car's computer through a wireless system to make sure that the right key is in the ignition. The Cars Immobiliser system lets the car start once the chip has been checked. There are different types of transponder chips for different car makes and models, and each type needs to be used with the right car.

What is an immobiliser system?

Modern cars have immobiliser systems that are state-of-the-art. Advances in immobiliser technology have made it impossible for thieves to hot-wire or get around a car's immobiliser system to start the engine. Since 1997, almost every car made in the world has had a cutting-edge immobiliser system that is always getting better and making the car safer. Even though each vehicle immobiliser system is a little different from the others, they all have something in common: a transponder chip. A tiny RFID (Radio-frequency identification) chip called a "transponder" stores a code that only works with that particular chip. Transponder chips don't need batteries to work. Instead, a tiny copper coil inside the chip acts as an antenna and gets a voltage from the magnetic field created by an antenna near the car's ignition. When you turn on your car, the code from the transponder chip on the head of the key is read by the antenna. If the code on the transponder chip is the same as the code in the engine or immobiliser ECU, the car will start. If the code doesn't match, the car won't start.

A smart key is a key intended to open a corresponding vehicle electronically. Some cars come with a smart key as a standard feature, while others let you add one as an option when you order the car from the factory. Newer models of smart keys are becoming more and more common.

Using a key that hasn't been programmed to start your car can lead to a lot of issues. When using a non-programmed key, every model of vehicle will behave differently. While some vehicles won't react at all, others will let the starter motor run while not starting the engine. If the engine is started with a non-programmed key, many cars will actually completely lock the car down and prevent any attempt at programming. If your car is in a lock out state then unlocking the vehicle from its lock out state can be time-consuming and expensive.

Troubleshooting Tips for a Volkswagen Ignition Lock Key That Won't Turn

Posted on: 01-20-2024

Introduction: If you've ever found yourself in a situation where your Volkswagen ignition lock key won't turn, you're not alone. It can be a frustrating experience, but before you panic or consider expensive repairs, there are several troubleshooting steps you can take to potentially resolve the issue. In this blog post, we'll guide you through some common reasons why this problem occurs and provide practical solutions to get you back on the road.

Check Your Steering Wheel: One of the most common reasons for a stubborn ignition lock is a locked steering wheel. Ensure that your steering wheel isn't jammed in a turned position. Gently try to turn the wheel in the direction it naturally moves while attempting to turn the key.
Park Gear Engagement: Ensure your vehicle is fully in the "Park" position if you have an automatic transmission or in the appropriate gear if you drive a manual. Sometimes, the ignition lock won't turn if the car doesn't detect it's in the correct gear.
Key Inspection: Examine your key for signs of damage or wear. A worn-out key might not engage the ignition pins properly. If the key appears damaged, consider using a spare or getting a replacement from your local dealership.
Lubricate the Ignition Cylinder: Over time, dirt and debris can accumulate inside the ignition cylinder, causing it to become stiff. Apply a small amount of graphite lubricant to the key and insert it into the ignition. Wiggle and turn the key gently to distribute the lubricant and loosen any debris.
Battery Check: In some cases, a weak or dead car battery can contribute to ignition issues. Ensure your vehicle's battery is in good condition, and if needed, jumpstart the car or replace the battery.
Anti-Theft System Reset: Modern vehicles often come equipped with anti-theft systems that can interfere with the ignition. Try locking and unlocking your car using the key fob or manually, and then attempt to start the engine.
Seek Professional Assistance: If the issue persists after trying the above steps, it's advisable to consult a professional automotive locksmith or your Volkswagen dealership. They have the expertise and tools to diagnose and fix more complex ignition problems. Conclusion: Encountering a Volkswagen ignition lock key that won't turn can be a frustrating experience, but with a systematic approach to troubleshooting, you may be able to resolve the issue without significant expense. Always prioritize safety, and if uncertain, seek professional assistance to ensure a reliable solution for your vehicle.
