Reprogramming Car Keys
Transponder keys are thought to be more secure for cars and are more difficult to copy by thieves. A key may have to be reprogrammed in the event that it is damaged or lost.
You can change the programming of your key fobs at home, but you should be aware of the proper procedure. For the best results you'll need the following items:
Keys
Nearly all modern vehicles require some kind of transponder fob or transponder keys to operate, providing security and protection against theft. The keys must be programmed to the specific vehicle and its features by a licensed dealer or locksmith. It's expensive to replace them if they become lost, so it's better to keep extras on hand. You can find replacement key fobs in online stores and many brick and mortar auto shops. How can you know that the key you purchased is authentic? Are you able to tell whether the unit has been programmed to work with another vehicle or if yours can be programmed again?
To program a new car key, you must first verify that your car is running. Insert the key you want to program into the ignition, but do not turn it. You have only a few seconds before the system will reset all commands and leaves the programming mode. It is important that you move quickly and don't delay between each step. To prevent this from happening, shut off the engine. You can test the system of your car by turning the key to the "on" position and then back to the "off" position. The door locks should be able to cycle, and you'll hear a sound that indicates that the process was successful.
Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to start the car. This feature is still vulnerable to a method known as replay attack which allows thieves to record the signal from the vehicle's key fob, then reproduce it to unlock the car. To prevent this, manufacturers have added security features known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.

Certain manufacturers also employ special encryption on their key fobs, which cannot be decoded by an easy program. These kinds of cars require programming by a professional, so you should only attempt this process if you have experience working with electronic devices. Refer to the manual for your car or go to the manufacturer's website to learn how to program it. The steps are different depending on the model of vehicle.
Transponder chips
Car keys that feature transponder chips require a special reprogramming to work. While any hardware store can cut keys for you, the real issue is how to integrate it with your specific car. The key needs to be programmed to match the exact identification code on your vehicle, or else it won't be able to start.
Transponder chips, which are used to stop theft of cars are a standard feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the key is placed in the ignition. The car then recognizes the signal and then starts the engine if it matches the original signal that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it more difficult for thieves with no experience to connect a vehicle to a hot wire and then start it.
The key and the chip are connected by the circuit board which includes an induction coil. When the key is placed in the ignition, it creates an electric field around the transponder. This creates a signal that gets taken up by the coil, which transmits it to the key's identification number. The key's identification code is transmitted back to the car and the engine is started when the identification number matches.
There are automotive key programming to program a key transponder, however all require a special tool. You can buy these tools online or from most locksmiths in the automotive industry. These tools are not expensive, but they are essential for programming your car's chip.
You may also use a reprogrammable transponder key that has been previously programmed for a different vehicle. In this instance, you'll need to make sure that the key is not damaged or the transponder has been altered in any way. The chip can be read with a scanner, or a computer with a USB connector.
Reprogramming an transponder is a simple procedure, but it requires specific software. It also requires an scanner tool. It is recommended to contact an auto locksmith for help for those who are new to the process. It is also recommended to avoid purchasing second-hand keys, since they are likely already programmed and won't work with your vehicle.
EZ Installer
For decades, car owners who required replacement of their key fob had no choice than to visit an auto dealer to get their key paired to the vehicle. This is because modern keys have to be "paired" to a specific vehicle to function in a way that required the use of expensive and complicated equipment that only dealers had access to. The EZ Installer by Car Keys Express simplifies the process of pairing modern keys to vehicles for locksmiths and retailers.
The EZ Installer, a basic "plug-and-play" OBD device, pairs new keys with vehicles without the use of complex equipment or tokens for programming. It connects directly to the vehicle's standard OBD port and using an app on mobile devices to provide easy-to-follow instructions. The EZ Installer works with all newer vehicles, including those with proximity keys or push button start. Check the compatibility guide at Tom's website to see whether your vehicle is compatible.
A full-money-back guarantee is provided if the device does not successfully program a remote or key purchased from Tom's for a vehicle that is compatible.
In contrast to traditional programming equipment, which costs retailers and key professionals tens of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these costs. It is able to be used as long as a key professional or retailer needs. The EZ Installer eliminates the need for expensive monthly service contracts and software updates. This lets retailers save money while giving their customers the same high-quality service as OEM equipment. It also comes with a renowned warranty that covers both hardware and software for the remainder of your life.
