Programming Car Keys

As automobiles have become more electronic and car keys cut and programmed more electronic, key programming has been an important service that can bring in a lot of revenue. But many shops don't offer this service.

Modern fobs and keys are more than just fobs - they can start the car remotely and even open the rear hatch, and protect the vehicle from physical and virtual attacks. You need to know how to program them.

What is a transponder?

A transponder car key comes with a security feature to prevent theft built in. This is achieved by incorporating an RFID microchip into the plastic head portion of the key. This chip is used to relay a signal to your vehicle's immobilizer in the ignition start-up process. This stops hot-wiring of the car and makes it very difficult to steal your vehicle.

However, this does not mean that transponder keys are secure, because although they provide an extra layer of security it does not mean that criminals can no longer utilize their expertise to break into the vehicle. It simply means that it takes longer and more effort to accomplish this, which is why this security feature is an enormous benefit to anyone who is concerned about the security of their vehicles.

Transponder keys are easy to use. The microchip in the head of the transponder key is programmed to contain an individual serial number that is a match for the immobilizer in your vehicle. When you insert the key into the ignition the immobilizer system will recognize the serial number and validate it. If the serial number matches the engine will start.

There are a variety of transponder chips that can be programmed. The type of chip your vehicle uses will determine the kind of key you own. You can determine the best transponder chip to match your vehicle by searching on a search engine or going to a professional locksmith and asking them what kind of key you have.

Transponder keys are more expensive to replace because of the microchip. The dealership that sells your vehicle is the most expensive option to replace your key since they have the highest overhead. However, you can also go to locksmiths to purchase a new key.

Another important thing to be aware of is that you can only program the transponder key only if it has not been cut previously. You can attempt to do it yourself by purchasing a transponder chip from one of the many stores offering these services, but you will require a special device to complete the task.
