Reprogramming Car Keys
Transponders in car keys are believed to make vehicles more secure and less likely to be duplicated by thieves. The key could need to be reprogrammed in event of damage or lost.
You can program key fobs yourself but you must be aware of the proper procedure. You should have these items to ensure the most effective results:
Keys
Almost all modern cars require a transponder fob or transponder keys to operate, ensuring security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with the car's systems and specific model. It's expensive to replace them if they are lost, so it's a good idea to keep extras on hand. You can also find replacement key fobs in various online stores and in many brick-and-mortar auto shops. How can you know that the one you purchased is genuine? Can you tell whether the unit has been programmed to work with another vehicle, or if it can be reprogrammed?
If you want to program a new key first, you need to ensure that your vehicle is running. Insert the key you'd like to reprogramme into the ignition, but do not turn it. There are only a few seconds before the system resets all commands and then exits the programming mode. It is crucial to move quickly and don't delay between each step. Stop the engine to prevent this. You can check the car's security 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'll hear a chime signalling that the process was successful.
Certain vehicles of recent years use rolling key technology to prevent thieves from using stolen keys to open the vehicle. This feature is still vulnerable to a technique called a replay attack. It allows thieves to record and reproduce the signal from the key fob of the vehicle to unlock the car. To stop this, manufacturers have added a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers employ a specific encryption on their keys, which can't be decoded with a simple program. These types of vehicles require programming by a professional, so you should only attempt this process if you have experience working with electronics. It is recommended to consult the owner's manual for your car or look up the manufacturer online, as the steps differ based on vehicle model.
Transponder chips
Car keys with transponder chips require a specific reprogramming to work. Any hardware store can give you an entirely new car key, but the real challenge lies in implementing it to your car. A key that has been reprogrammed will need to match the exact identification number of your vehicle otherwise it won't even start the engine.
Transponder chips are a typical feature in modern cars and are designed to prevent car theft. The chip is a microcircuit which transmits a radio frequency signals when the key is placed in the ignition. The car can detect the signal and begins the engine only if it matches the one programmed into the vehicle. The car also shuts down if a frequency is not valid. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is placed in the ignition the magnetic field is created around the transponder. This generates a signal that is received by the coil before being sent to the key's identification number. The ID number of the key is sent back to the vehicle, and if it matches, the engine will begin to run.
There are many ways to program a key transponder, however each requires a special tool. You can purchase these tools online or from most locksmiths in the automotive industry. These tools aren't inexpensive, but they are vital to program your car's chip.
You could also use a unreprogrammable key that was programmed for another vehicle. In this scenario, make sure the key isn't damaged or that the transponder is not altered in any way. To check this, you'll need scanners or computers with an USB port to read the chip and determine its identity.
Reprogramming a transponder is a simple procedure, but it requires special software. It also requires an scanner tool. If you're a beginner, it's best to seek out the help of an auto locksmith. Avoid buying used keys because they might already be programmed and won't work with your vehicle.
EZ Installer
For a long time, owners of cars who required replacement of their key fob had no alternative than to visit a dealer to get their key linked to their vehicle. This is because modern keys have to be "paired" to a specific vehicle to function and work, which required the use of expensive and complicated equipment that only dealers had access to. The EZ Installer from Car Keys Express solves this problem for locksmiths and retailers by simplifying the process of connecting modern keys to vehicles.
The EZ Installer is a basic, "plug and play" OBD device that pairs new keys to vehicles, without the need for complicated equipment or programming tokens. It connects directly to the standard OBD port of the vehicle and utilizes an app that can be downloaded on mobile devices to provide easy to follow instructions. The EZ Installer is compatible with most newer vehicles, including those with proximity keys or push button start. To see if it will work with a specific vehicle, refer to the compatibility guidelines on Tom's site.
If the device fails to program the remote or key purchased from Tom's into a compatible vehicle then a full refund is available.
In contrast to traditional programming equipment, which costs key retailers and professionals tens of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these costs. It is available for as long as a key professional or retailer requires. The EZ Installer eliminates the need for expensive monthly service contracts and software updates. This lets retailers save money while providing their customers the same high-quality service as OEM equipment. It also comes with a renowned warranty that covers hardware and software for the remainder of your life.
