Making Transponder Keys for BMW and Mercedes-Benz


By on


If your BMW or Mercedes-Benz was made after 2000, then you likely have a transponder key. A transponder key is specially made essentially to prevent theft. Each transponder is equipped with a small microchip, along with the key. When you insert the key, the car and the chip recognize each other, and your car is given the green light to start.


We hear a lot of questions from our customers regarding the cost of transponder keys. Why are they so expensive? The transponder key's microchip is the main factor. The key itself is very inexpensive, but that little chip is costly. Without the chip, however, your car will not start. For instance, you can get a duplicate of the key only, but your car won't start without the microchip.


If you're reading this article, it's probably due to one of the following reasons: you've lost your key, you've accidentally destroyed your key, or you need an extra. All of these reasons make it necessary to get a new transponder key for your BMW or Mercedes-Benz. If you've lost your key or it's been destroyed, then you won't be able to crank your vehicle at all. If you only have one transponder key, then you can avoid time and money down the line if the original is lost or destroyed.
