Replacement Transponder Keys


Most people don’t realize this but a Transponder Key, auto key fob and a Remote Key Combo are three entirely different things. A Transponder key provides a built-in keyless entry also known as an anti-theft system. In doing so, it makes them more secure than ever. Working on the principle of radio waves transmission between the chip and the car’s ignition system, the transponder key allows car owners to start their car or truck with the embedded microchip. A transponder key, even of the same make and model will only work for the one precise car in which it was designed for. This technology sure has made our lives easier and our cars and trucks more secure. These wonderful keys come with your car, truck or RV from the factory. They have a specially programmed micro chip installed in them which work with a code.

The code, more commonly known as the serial number is installed in the chip which is then embedded into the transponder key. When inserted into the ignition, the electrical engine control unit will scan the code within and if it matches with the serial number programmed into its system, then only will the truck or car start. If the ECU cannot validate the code, the car will not start which makes it all the more protected and secure. Having this type of feature on your vehicle means more security and theft protection. When such security systems come with your new car or truck they are relatively cheaper but if you want to get it installed in your older cars, it means spending a few hundred dollars. Also when a lost transponder key situation arises, it is extremely expensive to replace at your local car dealer.
