A "Transponder Key" refers to the key you use to start your car. The bulky black part of your key contains a "Transponder Chip". It is a computer chip that contains a code that is known by the computer in your car. If you were to take that chip out of the key your key would not start your car. So, how it works is as follows. When the ignition switch is turned on the computer in the car sends out an electrical impulse. This electrical impulse is picked up by the chip which sends a specific code back to the cars computer. The chip has no battery, it receives enough power from the electrical impulse to power itself long enough to send the code to the cars computer. I know this why? Because I lost the ONLY key to my Ford focus and am going to be spending somewhere around 90 dollars to get it fixed. They are an expensive piece of equipment so be careful about dropping your keys and what-not. Matt

Will the transponder key keep a 99 Jeep Laredo from starting?
Normally it would only cause a problem if the transponder key had severe damage or trying to start the car without the transponder. If the key looks ok and there's no damage to the sstem then it's probably not the transponder system causing the problem. The dealership could figure this out.
