Reprogramming Car Keys
Transponders in car keys are thought to keep cars more secure and are more difficult for thieves to duplicate. However, a key might need to be reset if it becomes damaged or lost.
You can change the key fobs you own but you must be aware of the correct process. For the best results you'll need the following items:
Keys
Almost all modern cars require some kind of transponder fob or transponder keys to work, which provides security and protection against theft. These keys must be programmed to your specific vehicle and its systems by an authorized dealer or locksmith. They are costly to replace if lost and it is recommended to keep spare keys in the car. You can find key fobs that can be replaced in online stores and many brick and mortar auto shops. But how do you know that the new key fob you bought is authentic? Can you tell whether the unit has been programmed to work with another vehicle or if yours can be programmed differently?
To program a new car keys, first make sure that your vehicle is running. Insert the key you want to program into the ignition, but do not turn it. You have only a few seconds left before the system resets all commands and then exits the programming mode. It is important that you be quick and don't delay between each step. Stop the engine to prevent this. You can test the car's system by turning the key to the "on" position and then back to the "off" position. You should hear a chime to indicate that the process was successful. The door locks will cycle.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the car. This feature is still susceptible to a technique dubbed a replay attack. It allows thieves to record and then reproduce the signal received from the vehicle key fob to unlock the car. To stop this, manufacturers have added an additional security feature known as the CAN bus protocol to prevent attacks on hacking.
Certain manufacturers also have special encryption on their key fobs that cannot be decoded with an easy program. You should only attempt this method if you have experience is in electronics. It is recommended to read the owner's manual for your car or search for the manufacturer on the internet, since the steps differ based on car model.
Transponder chips
Transponder chip car keys require a specific reprogramming to work. While any hardware store can cut keys for you, the biggest problem is to make it work to work with the specific car you own. A key that has been reprogrammed will need to match the specific identification number of the vehicle or else it won't be able to start the engine.
Transponder chips are a standard feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit that transmits a radio frequency signals when the key is inserted into the ignition. The car then scans for the signal and then starts the engine if it matches the original signal that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it much harder for thieves who are not experienced to wire a vehicle and then start it.
The chip and the key are connected via the circuit board which includes an induction coil. When the key is placed in the ignition, a magnetic field is generated around the transponder. car key programming generates a signal, which is absorbed by the coil before being sent to the key's identification number. The key's identification number is then sent back to the car, and the engine starts if the identification number matches.
There are many ways to program a transponder key, however, all require an instrument that is specifically designed for the purpose. These tools are available through the internet or from many automotive locksmiths. They are not cheap, but they are essential for programming the chip into your vehicle.
You could also use a unreprogrammable key that was programmed for another vehicle. In this instance, you'll need to make sure that the key is not damaged or that the transponder has been altered in any way. To accomplish this, you'll need scanners or computers with a USB port to scan the chip and determine its identity.
Reprogramming an transponder is a simple process, but requires specialized software. It also requires an scanner tool. It is best to consult an auto locksmith for help for those who are new to the process. Don't buy used keys since they could already be programmed and will not work with your car.
EZ Installer
Until recently the time when car owners wanted to replace their keys were required to visit an agent to have it electronically linked to the vehicle. This is because modern keys have to be "paired" to a specific vehicle to function in a way that required the use of expensive and complicated equipment that only dealers had access to. The EZ Installer from Car Keys Express solves this issue for locksmiths and retailers by easing the process of pairing modern keys with vehicles.
The EZ Installer, a simple "plug-and-play" OBD device, pairs new keys with vehicles without the need for complicated equipment or tokens for programming. It connects directly to the vehicle's standard OBD port and using an app on mobile devices to provide easy-to-follow instructions. The EZ Installer works with all newer vehicles, including those with proximity keys or push button start. Check the compatibility guide at Tom's website to see whether your vehicle is compatible.
If the device is unable to program a remote or key purchased from Tom's into a vehicle compatible the full refund will be offered.
In contrast to traditional programming equipment that costs retailers and key professionals thousands of dollars in typical per-key "token" costs, the EZ Installer Pro doesn't charge these fees at all, so it can be used for as long as a retailer or key professional wishes to keep it. 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 top quality service as OEM equipment. It also comes with an industry-leading warranty that covers all hardware and software for life.
Tools
Car key programming tools are used by auto technicians, locksmiths and owners of vehicles to program new keys for their automobiles. These tools connect to a vehicle's immobilizer in order to program new keys, and are remotely controlled. They can also be used to clone existing keys and create duplicate keys. These tools are a useful tool for those who own a car.
