I lost my keys while going on a run. I called Top Atlanta Locksmith LLC and the tech was fast, efficient, and professional. Oh and reasonably priced. I scoured the web for quotes and they were the lowest in price.

How Do Transponder Keys Work?

Almost every modern vehicle use transponder keys. It’s an item that people across the country use several times a day, yet there are a lot of misconceptions. Many are curious to know how they work in the first place, and what their purpose is. It’s important to know how they function, so that if you run into an issue with your transponder key, you’ll know what to do. At Top Atlanta Locksmith, we help drivers in Sandy Springs, Roswell, Smyrna, Brookhaven and all surrounding Metro Atlanta area communities. One of the most common service requests involves transponder keys, and a little knowledge can go a long way in getting the right help for your car’s locks and keys. 

What is a Transponder Key?

Not to be confused with the remote, a transponder key works in conjunction with your vehicles immobilizer. Your remote will allow you to quickly lock and unlock your car from a distance, but your immobilizer keeps the engine from starting when your transponder key is absent. The chip inside your key allows you, and only those with your unique key, to start the ignition and drive away. It’s a safety feature that helps deter and prevent car theft. When you place your key in the ignition, an electronic signal is sent back and forth from the engine control unit to the key’s chip. If the key’s data doesn’t match up, your car won’t start. 

Why do People Prefer Transponder Keys?

Cars are often people’s second largest investment, second only to their mortgage. Transponder keys are an excellent way to keep criminals from stealing your vehicle, because the immobilizer will make it extremely difficult for the engine to start without the correct key. Most thieves prefer an easy target that can be taken quickly and without notice. When coupled with a top of the line automotive security system, you’ll have much better odds that your favorite car stays where you parked it. 


Transponder keys do such a wonderful job of keeping burglars at bay, that when you lose your key, or the chip malfunctions, getting your car to start becomes close to impossible. While towing your car back to the dealership for a replacement is an option, it’s often time consuming and extremely costly. Many people don’t realize that a professional locksmith has all the tools and skills needed to duplicate and reprogram transponder keys. Rather than wait days for your local dealership to get the job done, our team of mobile technicians can meet you at your location immediately. Save yourself time and money by calling the experts at Top Atlanta Locksmith and you’ll be back on the road in no time.
