What is an Auto Key Programmer and Why Would You Need to Buy One?

by | Oct 9, 2019 | Auto Parts

Today, more and more cars are coming equipped with extra security measures. One of these that is becoming increasingly common is the use of transponder keys to start your car. Unlike the standard metal keys of older makes and models, this new electronic component to ignition keys makes stealing your vehicle tougher, but also adds an extra step to getting a new ignition key made. This extra step requires the use of an auto key programmer.

Transponder keys are car keys that have a special chip inside the ends of them. These transponder chips tell the car that the correct key is being used to start the key, or that there is even a key there at all. Transponder keys that are not working properly or programmed correctly will still open doors, trucks, and other locks but will not start the vehicle.

To have a transponder key replaced, you will either have to have an auto key programmer or go to a professional who does. They can order a blank key with a transponder chip that has never been used. It is possible to do the auto key programming yourself, but it can be tricky if you are inexperienced with the process. This device will allow you to set up your new key so it works specifically with your make and model.

If you are unsure whether you have a transponder chip on your keys or not, there is an easy way to check. Generally speaking, if your car keys have a large plastic cap on the end, that is likely housing the electronics for a transponder chip. These cases can be unscrewed and opened to check for a transponder chip. If you do this, it is important to not scratch, touch, or damage the transponder chip in any way.
