Reprogramming Car Keys
Transponder keys are thought to be more secure for cars and harder to copy by thieves. However, a key may require reprogramming if it becomes damaged or lost.
You can program key fobs yourself but you must be aware of the correct process. You must have these things to get the most effective results:
Keys
Almost all modern cars require some kind of transponder fob or transponder keys to operate, ensuring security and protection against theft. The keys are programmed by a locksmith or authorized dealer to function with the car's systems and specific model. It's expensive to replace them if they're lost, so it's a good idea to have spares in your possession. You can find key fobs that can be replaced in online stores and many brick-and mortar auto shops. How can you be sure that the one you bought is genuine? Are you able to tell whether the unit is programmed to work with a different vehicle or if yours can be reprogrammed?

To program a new car key you must first ensure that your car is running. Insert the key that you wish to program into the ignition, but don't turn it. There are only just a few seconds before the car's system reverts the commands and exits programming mode. Therefore, it is important to move quickly and not wait between steps. Turn off the engine to prevent this. Change the key from "on" to "off" to test the system. You should hear a sound signalling that the procedure was successful. The door locks will go through a cycle.
Certain vehicles of recent years use rolling keys to stop thieves from using stolen keys to start the car. The technology is still susceptible to a method known as replay attacks that allows thieves to record the signal of the vehicle's key fob, then reproduce it to open the car. To stop this, manufacturers have added a security feature called CAN bus protocol to stop attacks on hacking.
Certain manufacturers have a unique encryption on their keys that cannot be decoded by a simple program. You should only attempt this method if you have experience is with electronics. Consult your car's manual or go to the manufacturer's website for information on how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Transponder chip car keys require a special reprogramming to work. While any hardware store can cut a new key for you, the biggest challenge is making it function with your specific car. The key needs to be programmed to match the exact identification number of your car, or else it won't start.
Transponder chips are a standard feature of modern cars and are designed to prevent car theft. The chip is a microcircuit which emits a radio frequency signal when the key is put into the ignition. The car then recognizes the signal and then starts the engine if it is in line with the original signal that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for thieves with no experience to hot-wire a vehicle and then turn it on.
The chip and the key are linked by the circuit board which includes an induction coil. When the key is placed in the ignition, it creates a magnetic field around the transponder. This creates a signal that is absorbed by the coil, which then transmits it to key's identification number. The key's identification code is returned to the car, and the engine starts when the identification number matches.
There are many ways to program a transponder key however, they all require an appropriate tool. These tools can be purchased on the internet or at most auto locksmiths. These tools aren't cheap but are essential for programming your car's chip.
You could also make use of a transponder key that can be reprogrammed 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. You can read the chip using a scanner, or a computer equipped with a USB connector.
Reprogramming an transponder is a simple process, but requires specific software. It also requires a scanner tool. It is best to consult an auto locksmith for assistance if you're a novice. Avoid buying used keys as they may already be programmed and won't be compatible with your vehicle.
EZ Installer
For decades, car owners who required replacement of their key fob had no alternative than to visit a dealership to have their key electronically connected to the vehicle. This is because modern keys need to be "paired" to a specific vehicle to function, which 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 with vehicles for locksmiths and retailers.
The Easy Installer, a straightforward "plug-and-play" OBD device, connects new keys to vehicles without the use of complicated equipment or tokens to facilitate programming. It connects directly to the standard OBD port on the vehicle and uses 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. Go to the compatibility guide on Tom's website to determine whether your vehicle is compatible.
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 offered.
Unlike 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 for as long as the key professional or retailer needs. The EZ Installer eliminates the need for expensive monthly service contracts and software updates. This allows retailers to save money while offering their customers the same high quality service as OEM equipment.
