Reprogramming Car Keys

Transponder keys are said to be more secure for vehicles and more difficult to copy by thieves. However, a key may require reprogramming in the event that it is damaged or lost.

You can change the programming of your key fobs at home, however you should be aware of the correct procedure. You should have these items to get the most effective results:

Keys

Most modern vehicles require a transponder key programmer key or fob to operate, providing security and protection against theft. These keys must be programmed to your particular vehicle and its features by a licensed dealer or locksmith. They are costly to replace in the event of loss, so you should have spares in your car. You can find key fobs that can be replaced in online stores, as well as many brick-and mortar auto shops. How can you ensure that the one you bought is authentic? Can you tell if the unit has been programmed to work with a different vehicle or if yours can be programmed again?

If you want to program a new key first, you need to ensure that your vehicle is running. Insert the key you want to program into the ignition, but do not turn it. You will only have a few seconds before the car's system reverts the commands and leaves programming mode. It is important that you be quick and don't be patient between each step. Turn off the engine to avoid this. Switch the key from "on" to "off" to test the system. The door locks should be able to cycle, and you'll hear a chime to indicate that the process has been successful.

Some newer vehicles use rolling keys to keep thieves from using stolen keys to open the car. The technology is still susceptible to a technique known as replay attack that allows thieves to record the signal received from the key fob on the vehicle, then reproduce it to unlock the car. To stop this, manufacturers introduced the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.

Certain manufacturers also have special encryption on their key fobs which cannot be decoded by an easy program. These kinds of cars require programming by a professional, and you should only attempt this procedure if you have experience working with electronic devices. Refer to the manual for your car or visit the manufacturer's website for information on how to program it. The steps will vary depending on the model of vehicle.

Transponder chips

Car keys with transponder chips need special reprogramming to work. While any hardware store can cut keys for you, the biggest problem is to make it work with your specific car keys programmed. A key that has been reprogrammed will need to match the specific identification number of your vehicle otherwise it won't even start the engine.

Transponder chips are a common feature in modern cars and are designed to stop car theft. The chip is a microcircuit which transmits a radio frequency signals when the key is placed in the ignition. The car is able to detect the signal and starts the engine only if the signal is in line with the one programmed in the vehicle. The car will also shut down if the frequency is invalid. This makes it more difficult for car thieves with no experience to wire a vehicle and start it.

A circuit board that has an induction coil connects the chip to the key. When the key is inserted into the ignition, it creates an electric field around the transponder. This creates a signal which is received by the coil and sent to the key's identification number. The ID number of the key is then sent back to the vehicle and if it matches the engine will begin to run.

There are a variety of ways to program a transponder, but all of them require a special tool. You can purchase these tools on the internet or at many automotive locksmiths. They're not cheap, but they are vital for programming the chip to your car.

You may also utilize a transponder that is reprogrammable that was previously programmed for a different vehicle. In this case you'll need to make sure that the key isn't damaged or the transponder been altered in any way. The chip can be read with a scanner, or a computer that has the USB connector.

The process of reprogramming the transponder key is simple, but it requires special software and a scanning tool. If you're just beginning, it's best to seek help from an auto locksmith. Avoid buying used keys as they could already be programmed, and they won't work with your car.

EZ Installer

In the past the time when car owners wanted to replace their key fob were forced to go to an agent to have it electronically linked to the vehicle. This is because modern keys need to be "paired" to the vehicle of the owner in order to work, which required the use of expensive and complex equipment that only dealers could access. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys to vehicles for locksmiths and retailers.

The Easy Installer is a straightforward, "plug and play" OBD device that pairs new keys to vehicles, without the need for complicated equipment or programming tokens.

The EZ Installer works with a wide range of modern vehicles that include proximity keys or push-button start. Check the compatibility guide at Tom's site to see if your vehicle is compatible.

A full-money-back guarantee is provided in the event that the device fails to successfully program a key or remote purchased from Tom's for a vehicle that is compatible.

The EZ Installer also eliminates the necessity for expensive monthly service contracts and updates, so it could save retailers money while still providing the same quality service as OEM equipment.
