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 in the event that it is damaged or lost.
You can change the programming of your key fobs at home, but you must be aware of the correct procedure. For the best results you should have the following items:
Keys
Most modern cars require a transponder key to operate. This provides security and protection against theft. These keys are programmed by a locksmith or an authorized dealer to work with the car's systems and specific model. They are expensive to replace if lost, so you should keep extras handy. You can also find replacement keys fobs in various online stores and in many brick-and-mortar auto shops. But how can you tell that the one you have bought is genuine? Can you tell if the unit has been programmed to work with another vehicle or if it could be programmed differently?
If you want to program an entirely new key first, you need to ensure that your car is operating. Insert the key you wish to program into the ignition without turning it. You only have just a few seconds before the car's system resets the commands and exits programming mode. This is why it is crucial to be quick and not pause between steps. Shut off the engine to avoid this. You can check the system of your car by turning the key to the "on" position and back to the "off" position. The door locks should be able to cycle, and you'll hear a chime signalling that the procedure was successful.
Some newer vehicles use rolling keys to stop thieves from using stolen keys to start the vehicle. This feature is still vulnerable to a technique known as replay attacks which allows thieves to record the signal received from the key fob on the vehicle and reproduce it later to unlock the car. To combat this, manufacturers added the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Some manufacturers also use special encryption on their key fobs which are not decoded by an easy program. You should only attempt this method if your previous experiences are with electronic devices. Check the manual of your car or go to the manufacturer's website for information on how to program it. The steps to follow will differ depending on the type of vehicle.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. Any hardware store can offer you a new car key, but the real challenge is in implementing it to your car. The key you reprogrammed needs to match the exact identification number of your vehicle otherwise it won't even start the engine.
Transponder chips, used to prevent car theft are a standard feature of modern cars. The chip is a microcircuit which transmits a radio frequency signals when the key is placed into the ignition. The car can detect the signal, and starts the engine only if the signal is in line with the one programmed in the vehicle. The car is also programmed to shut down when it detects an incorrect frequency. This makes it difficult for novice car thefts to connect a vehicle to a hot wire and then turn it on.
A circuit board with an induction coil connects the key to the chip. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This generates a signal that is received by the coil before being sent to the key's identification number. The key's identification number is returned to the car and the engine will start when the identification number is in line with.
There are many methods to program a transponder key, however, they all require a special tool. You can purchase these tools on the internet or at many locksmiths in the automotive industry. These tools are not cheap but are essential to program your car's chip.
You could also make use of a transponder key that can be reprogrammed that has been previously programmed for a different vehicle. In this case, make sure that the key hasn't been damaged or that the transponder isn't altered in any way. To check this, you'll need a scanner or a computer with an USB port to scan the chip and determine its identity.
The process of reprogramming the transponder key is easy, but it will require an expertly designed software and scan tool. If you're a beginner, it's best to seek the assistance of an auto locksmith. Don't buy used keys since they could already be programmed and will not work with your vehicle.
EZ Installer
In the past, car owners who wanted to replace their key fob had 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 expensive and complex equipment that only dealers had access to. The EZ Installer from Car Keys Express solves this issue for retailers and locksmiths by easing the process of connecting modern keys to vehicles.

It connects directly to the standard OBD port of the vehicle and uses an application that is mobile that provides easy-to-follow instructions. The EZ Installer works with all newer vehicles, including those with proximity keys or push button start. To determine if it'll work with a specific vehicle, check the compatibility guide on Tom's website.
A full-money-back guarantee is provided if the device does not successfully program a key or remote purchased from Tom's for a compatible vehicle.

It is available as long as a key professional or retailer needs. The EZ Installer eliminates the need for costly monthly service contracts and software updates. This lets retailers save money while giving their customers the same high-quality service as OEM equipment.
