How Transponder Keys Work

If you drive a modern vehicle, then there is a good chance that you use transponder keys every day. While you likely appreciate the added security benefits and convenient features that these high-tech car keys provide, you may also be curious about how they work. At Locks Pros, we offer premium residential, commercial, and automotive mobile locksmith services including transponder key programming and car key replacement. Read below to discover how transponder keys perform their job, and what you can do if you have problems with your car keys. 

Advantages of Transponder Keys 
Transponder keys offer many great benefits. Perhaps the most important rewards of these modern devices are the enhanced security, which makes it much more difficult for criminals to steal your car. If you drive an older car model or classic vehicle that still uses a manual key, it might be time for you to consider upgrading. Today’s car keys offer not only protection against theft but can also provide remote start and other advanced features. 

How Do Transponder Keys Work? 
Transponder keys have a built-in computer chip that is used to deactivate your engine immobilizer. The engine control unit, or ECU, sends a signal to your key when the ignition is turned on. Inside the key is an induction coil, which generates an electromagnetic field that can be used to power the transponder microchip that sends the signal to the ECU. The key has a unique alphanumeric code that is distinct. If the wrong key is inserted, the electronic message will not be received, and the car will not start.

What Should You Do If You Run into Issues with Your Transponder Keys? 
While transponder keys offer high-security features, they can also be a major problem for car owners when they refuse to work properly. There could be a variety of reasons why your transponder key is not functioning correctly, including a broken ignition or damaged chip. In some cases, the key may need to be reprogrammed. In the early days of transponder keys, many drivers were forced to go to their dealership for a new set of keys. This process could be time-consuming, stressful, and expensive. Now, thanks to advancements in technology and manufacturing, mobile locksmiths have specialized equipment that allows us to bring the necessary tools on the road. Today’s locksmiths can fix your problem on-site, and provide services that are fast, affordable, and convenient. The experts at Locks Pros offer professional automotive locksmith services including key replacement, ignition repair, transponder key programming, emergency lockout assistance, and more.
