Reprogramming Car Keys
Transponder keys are said to be more secure for cars and are more difficult to copy by thieves. However, keys may need to be reset when it becomes damaged or lost.
You can program key fobs yourself, but you must know the correct process. For the best results you should have the following items:
Keys
Most modern vehicles require a transponder fob or transponder keys to operate, providing security and protection against theft. The keys must be programmed to your particular vehicle and its features by a licensed dealer or locksmith. It is expensive to replace them if they're lost, so it's better to have spares available. You will also find replacement key fobs on various websites and in many brick-and-mortar auto shops. How can you know that the one you bought is authentic? Are you able to tell whether it was programmed to work with another vehicle or if it is able to be reprogrammed for yours?
To program a new car key, first make sure that your car is running. Insert the key that you'd like to reprogramme into the ignition, but do not turn it. There are only a few seconds before the system will reset all commands and exits the programming mode. This is why it is crucial to move quickly and not be able to wait between steps. To prevent this from happening, turn off the engine. You can check the system of your car by turning the key to the "on" position and then back to the "off" position. You should hear a sound to indicate that the process was successful. The door locks will go through a cycle.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the car. programming car key is still vulnerable to a method known as replay attack that allows thieves to record the signal of the key fob on the vehicle, then reproduce it to open the car. To prevent this, manufacturers have added a security feature called CAN bus protocol to stop attacks on hacking.
Certain manufacturers also employ special encryption on their key fobs which cannot be decoded by a simple program. These kinds of cars require programming by a professional, so you should only try this only if you've worked with electronics. It's a good idea to consult the owner's manual for your car or search for the manufacturer online, as the steps will differ depending on the vehicle type.
Transponder chips
Car keys with transponder chips require special reconfiguration to work. While any hardware store can cut keys for you, the real problem is to make it work to work with the specific car you own. The key must be programmed to match the exact identification code on your car, otherwise it won't be able to start.
Transponder chips are a standard feature of modern automobiles and are designed to prevent car theft. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is placed. The car detects the signal and starts the engine only if it matches the original that was programmed in the vehicle. The car also shuts down if a frequency is not valid. This makes it much more difficult for thieves who are not experienced to wire a vehicle and start it.
The key and the chip are linked by an electronic circuit board that contains an induction coil. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This creates a signal that gets taken up by the coil, which then transmits it to key's identification number. The key's identification code is sent back to the car and the engine is started if the identification number matches.
There are a variety of methods to program a key transponder, but all of them require the use of a specific tool. You can purchase these tools online or at most locksmiths in the automotive industry. They're not cheap, but they're essential for programming the chip in your car.
You can also use an unreprogrammable key that was programmed for an alternative vehicle. In this case, make sure that the key isn't damaged or the transponder isn't altered in any way. To do this, you'll need a scanner or a computer equipped with a USB port to scan the chip and determine its identity.
Reprogramming the transponder is a straightforward procedure, but requires specialized software. It also requires an scanner tool. If you're just beginning it is recommended to seek help from an auto locksmith. Don't buy used keys since they might already be programmed and will not work with your vehicle.
EZ Installer
Until recently those who wanted to replace their key fob had to go to an agent to have it electronically paired with the vehicle. This is because modern keys need to be "paired" to a specific vehicle in order to function, which required expensive and complicated equipment that only dealers had access to. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys with vehicles for locksmiths and retailers.
The EZ Installer, a basic "plug-and-play" OBD device, pairs new keys with vehicles without the need for complicated equipment or tokens to facilitate programming. 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 works with all newer vehicles, including those with proximity keys or push button start. To determine if it'll work with a specific vehicle, refer to the compatibility guide on the Tom's website.
A full-money-back guarantee is provided in the event that the device fails to successfully program a remote or key purchased from Tom's for a compatible vehicle.
Unlike traditional programming equipment that costs retailers and key professionals thousands of dollars with 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 retailer or key professional would like it to be. The EZ Installer also eliminates the necessity for expensive monthly service contracts and updates, meaning that it could save retailers money while providing customers with the same high-quality service as OEM equipment.
