Reprogramming Car Keys
Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. However, a key may need to be reprogrammed if it becomes damaged or lost.
You can reprogram your key fobs at home, however you must be aware of the proper procedure. To get the best results, you must have 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. The keys must be programmed to the specific vehicle and its systems by an authorized dealer or locksmith. It's costly to replace them if they become lost, so it's a good idea to have spares in your possession. You will also find replacement key fobs in various online stores and in many brick-and-mortar auto shops. How can you ensure that the one you purchased is authentic? Can you tell if the unit has been programmed to work with another vehicle or if yours can be programmed differently?
If you are planning to program an entirely new key first, you need to ensure that your vehicle is on and running. Insert the key that you'd like to reprogramme into your ignition, but do not turn it. You will only have a couple of seconds before the car's system resets the commands and exits programming mode. It is essential to move quickly and don't be patient between each step. Shut off the engine to stop this. Change the key from "on" to "off" to test the system. The door locks should cycle and you will hear a chime to indicate that the procedure was successful.
Some newer cars use a rolling key technology that prevents thieves from using stolen cars' key to open it. The feature is still vulnerable to a technique called a replay attack. It allows thieves to record and later duplicate the signal generated by the car key fob to unlock the car. To combat this, manufacturers have added a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys, which cannot be decoded by an ordinary program. You should only attempt this method if your previous experiences are with electronic devices. Refer to the manual for your car or go to the website of the manufacturer for information on how to program it. The steps are different according to the type of vehicle.
Transponder chips
Car keys that feature transponder chips require special reconfiguration to work. Any hardware store can make you an entirely new car key, but the real challenge lies in making it work with your vehicle. A key that has been reprogrammed will need to match the specific identification number of the vehicle otherwise it won't even start the engine.
Transponder chips, which are used to protect cars from theft, are a common feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the ignition key is placed. The car can detect the signal and begins the engine only if it matches the original that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for thieves who are not experienced to connect a vehicle with hot wires and start it.
The key and the chip are connected by the circuit board which includes an induction coil. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This generates a signal that is absorbed by the coil, which transmits it to the key's identification number. The key's ID number is transmitted back to the vehicle, and if it matches, the engine will begin to run.
There are many methods to program a key transponder, however each requires a special tool. These tools can be purchased through the internet or from many automotive locksmiths. They're not cheap, but they're vital for programming the chip to your vehicle.
You can also use an unreprogrammable key that was programmed for another vehicle. In this case, make sure the key isn't damaged or the transponder isn't altered in any way. The chip can be read by using a scanner or a computer that has an USB connector.
Reprogramming an transponder is a simple process, but requires specific software. It also requires a scanner tool. If you're new to the process you should seek the assistance of an auto locksmith. Avoid buying used keys because they may already be programmed and will not be compatible with your vehicle.
EZ Installer
For a long time, car owners who required replacement of their key fob had no other option than to go to a dealer to have their key electronically connected to the vehicle. This is because modern keys have to be "paired" to a specific vehicle to function in a way that required expensive and complex equipment that only dealers had access to. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys with vehicles used by retailers and locksmiths.
The EZ Installer is a simple, "plug and play" OBD device that connects new keys with vehicles without the need for expensive equipment or programming tokens. It works by connecting directly to the vehicle's standard OBD port and using an app for mobile devices to provide simple instructions. The EZ Installer works with all newer models, including those with proximity keys or push button start. Check the compatibility guide at Tom's website to see if your vehicle is compatible.
A full money-back guarantee is offered in the event that the device fails to successfully program a key or remote purchased from Tom's for a vehicle compatible.
Unlike traditional programming equipment that costs retailers and key professionals thousands of dollars through typical per-key "token" charges, the EZ Installer Pro doesn't charge these fees at all, so it can be used for as long as a key professional would like to use it. The EZ Installer also eliminates the requirement for expensive monthly service contracts and updates, meaning that it will save retailers money while still providing the same quality service as OEM equipment. It also comes with a world-class warranty that covers all hardware and software for the duration of its life.
