What is a Transponder Key?

Transponder key technology has dominated the market in the last decade. Many older cars still use traditional keys that can be copied easily and inexpensively at your corner Home Depot, but almost ever new car made in the last few years uses a Transponder key.

At Dallas Locksmiths we get the question quite a bit: What are transponder keys or chip keys? Transponder keys are keys that come with a microchip installed in them that sends a signal to the car’s ICU or Ignition Control Unit. This signal must be present for the car’s computer to start.

Most people are not aware that their car uses this system until they need to have a copy made. Expecting a cheap, simple copy (under 5$) they are instead confronted with extremely high prices at the dealership, ranging anywhere from $100-800 depending on the make and model of the vehicle.

So what is the purpose of a Transponder Key? Well, car thieves often break the ignition column to get the car to start. Therefore, the first purpose of the transponder key is to keep the ignition cylinder from being forced. The car will not start unless a transponder key is present.
