Reprogramming Car Keys
Transponder keys are believed to be more secure for cars and are more difficult to copy by thieves. The key could need to be reprogrammed in the event that it is damaged or lost.
You can change the key fobs you own however, you must be aware of the correct process. It is essential to have these items to get the most effective results:
Keys
Most modern vehicles require a transponder key or fob to operate, providing security and anti-theft protection. These keys are programmed by a locksmith or authorized dealer to function with your car's system and the specific model. They are costly to replace if lost, so you should have spares in your car. You can also find replacement keys fobs in various online stores and in many brick-and mortar auto shops. How can you know that the key you purchased is genuine? Are you able to tell whether it was programmed for another car or if it could be programmed to work with your car?
If you want to program a new key, the first step is to ensure that your car is operating. Insert the key that you wish to program into the ignition, but do not turn it. There are only a few seconds before the car's system resets commands and leaves programming mode. For this reason, it is important to move fast and not be able to wait between steps. To avoid programmed car keys happening, shut off the engine. You can test the car's system 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 will hear a sound that indicates that the procedure was successful.
Some newer cars use a rolling key technology, which stops thieves from using stolen cars' key to open it. This feature is still vulnerable to a technique known as replay attacks which allows thieves to record the signal received from the key fob of the car, then reproduce it to open the car. To combat this, manufacturers introduced a security feature known as the CAN bus protocols to stop hacking.
Some manufacturers also use special encryption on their key fobs, that cannot be decoded with a simple program. These types of vehicles will need to be programmed by a professional, so you should only attempt this process with someone who has experience with electronic devices. Check the manual of your car or look up the manufacturer's website to find out how to program it. The steps are different depending on the type of vehicle.
Transponder chips
Car keys that feature transponder chips need special reprogramming to work. While any hardware store can cut a new key for you, the real challenge is making it function with your specific car. A reprogrammed key will need to be compatible with the exact identification number of the vehicle otherwise it won't even start the engine.
Transponder chips are a standard feature of modern automobiles and are designed to stop car theft. The chip is a microcircuit that emits a radio frequency signal when the key is put into the ignition. The car then detects the signal and begins the engine if it is in line with the original frequency that was programmed into the vehicle. The car will also shut down if a frequency is invalid. This makes it much harder for novice car thieves to connect a vehicle with hot wires and start it.
The chip and the key are linked by an electronic circuit board that contains an induction coil. When the key is put in the ignition, a magnetic field is generated around the transponder. This generates a signal, which is taken up by the coil before being sent to the key's identification number. The key's ID number is then sent back to the vehicle, and if it matches the engine will begin to run.
There are many ways to program a transponder key, however, they all require a special tool. These tools can be purchased on the internet or at most auto locksmiths. They are not cheap, but they're crucial for programming the chip to your car.
You may also use a reprogrammable key that was previously programmed for a different vehicle. In this scenario, you'll need to make sure that the key is not damaged or the transponder been altered in any way. To check this, you'll need scanners or a computer equipped with a USB port to scan the chip and determine its identity.
Reprogramming a transponder is a simple process, but requires special software. It also requires the use of a scanner. It is best to consult an auto locksmith for help for those who are new to the process. Avoid buying used keys because they may already be programmed, and they won't be compatible with your vehicle.
EZ Installer
For decades, car owners who needed to replace their key fob had no other alternative than to visit a dealer to have their key electronically paired to the vehicle. This is because, in order for modern keys to function they must be "paired". This required expensive and complicated equipment that was available only to dealers. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys with vehicles for locksmiths and retailers.
The EZ Installer, a basic "plug-and-play" OBD device, connects new keys to vehicles without the use of complex equipment or tokens for programming. It connects directly to the standard OBD port of the vehicle, and runs an app that can be downloaded on mobile devices to provide easy to follow instructions. The EZ Installer works with most modern vehicles, including those that have proximity keys or push-button start. To see if it will be compatible with your specific vehicle, look up the compatibility guidelines on Tom's site.
If the device is unable to program a remote or key purchased from Tom's into a vehicle that is compatible, a full refund is available.
Contrary to conventional programming equipment that costs key professionals thousands of dollars through typical per-key "token" fees, the EZ Installer Pro doesn't charge any fees which means it can be used for as long as a key professional wishes to use it. The EZ Installer also eliminates the requirement for expensive monthly service contracts and updates, so it can save retailers money while still offering customers the same high-quality service as OEM equipment. It also offers a leading warranty that covers hardware and software for the rest of your life.

Locksmiths, auto mechanics, and owners of vehicles can utilize car key programming tools to create new keys for cars. These tools communicate with a vehicle's immobilizer to program new keys, and are remotely controlled. They can also be used to clone existing keys and create duplicate keys.
