Reprogramming Car Keys
Transponder keys are said to be more secure for cars and harder to copy by thieves. However, keys may need to be reprogrammed in the event that it is damaged or lost.
You can reprogram your key fobs at home, however you must be aware of the correct procedure. For the best results you should have the following items:
Keys
Most modern vehicles require a transponder key or fob in order to operate, ensuring security and protection against theft. The keys have to be programmed to the specific vehicle and its systems by a certified locksmith or dealer. They are costly to replace if they are lost, so it is recommended to keep spare keys in the car. You can also find replacement keys fobs on various websites and in many brick-and mortar auto shops. How can you be sure that the key you purchased is genuine? Do you know whether it was programmed to work with another vehicle or if it is able to be programmed to work with your car?
If you are planning to program a new key, the first step is to ensure that your vehicle is operating. Insert the key you want to program into the ignition, but do not turn it. You only have just a few seconds before the car's system reverts the commands and then exits programming mode. It is important that you be quick and don't wait between each step. Turn off the engine to avoid this. You can test the car's system by turning the key to the "on" position, then back to the "off" position. The door locks should cycle and you will hear a chime to indicate that the procedure was successful.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to open the vehicle. This technology is still vulnerable to a method known as a replay attack which allows thieves to record the signal of the key fob of the car and then replicate it to open the car. To stop this, manufacturers have introduced a security feature called the CAN bus protocol to stop attacks on hacking.
Certain manufacturers employ a specific encryption on their keys, which cannot be decoded by an easy program. These types of vehicles will need to be programmed by a professional, and you should only attempt this process if you have experience working with electronics. It's a good idea to read your car's owner manual or look up the manufacturer on the internet, since the steps will differ depending on the vehicle model.
Transponder chips
Car keys with transponder chips require special programming to function. Any hardware store can give you an entirely new car key, but the real challenge is in integrating it with your vehicle. The key must be programmed to match the exact identification code on your vehicle, or else it will not start.
Transponder chips, used to prevent car theft, are a common feature of modern automobiles. The chip is a microcircuit which emits a radio frequency signal when the key is inserted into the ignition. The car then scans for the signal and begins the engine if it matches the original one that was programmed into the vehicle. The car is also programmed so that it will shut down if it detects an invalid frequency. This makes it much more difficult for car thieves with no experience to wire a vehicle and start it.
A circuit board with an induction coil connects the key to the chip. When the key is inserted into the ignition it creates an electromagnetic field around the transponder. This produces a signal which gets taken up by the coil, which transmits it to the key's identification number. The key's identification number is transmitted back to the car and the engine is started when the identification number matches.
There are a variety of ways to program a key transponder, but all of them require a special tool. You can purchase these tools online or at most locksmiths for cars. They're not cheap, but they are crucial for programming the chip to your vehicle.
You may also use a reprogrammable key that was previously programmed for a different vehicle. In this instance, you'll need to make sure that the key has not been damaged or the transponder has been altered in any way. To check automotive key programming , you'll need a scanner or a computer equipped with a USB port to identify the chip and establish its identity.
Reprogramming an transponder is a simple procedure, but requires specific software. It also requires the use of a scanner. It is best to consult an auto locksmith for assistance if you're a novice. Also, avoid buying secondhand keys, as they're likely to be programmed and will not work with your vehicle.
EZ Installer
For a long time, car owners who required replacement of their key fob had no other choice than to visit an auto dealer to have their key connected to the vehicle. This is because in order for modern keys to function they must be "paired". This required expensive and complex equipment that was available only to dealers. The EZ Installer from Car Keys Express solves this problem for locksmiths and retailers by making it easier for connecting modern keys to vehicles.
The EZ Installer, a simple "plug-and-play" OBD device, pairs new keys with vehicles without the need for complex equipment or tokens for programming. It works by connecting directly to the vehicle's standard OBD port, and then using an app on mobile devices to provide simple instructions. The EZ Installer is compatible with the majority of newer vehicles that include proximity keys or push button start. Go to the compatibility guide on Tom's website to see whether your vehicle is compatible.

If the device is unable to program the remote or key purchased from Tom's into a vehicle compatible, a full refund is available.
Unlike traditional programming equipment that costs key professionals thousands of dollars through typical per-key "token" charges, the EZ Installer Pro doesn't charge these fees at all which means it can be used as long as a retailer or key professional would like to keep it. The EZ Installer also eliminates the need for costly monthly service contracts and updates, meaning that it can reduce costs for retailers while providing the same quality service as OEM equipment. It also comes with a renowned warranty that covers both hardware and software for the remainder of your life.
