Reprogramming Car Keys
Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. However, a key might need to be reprogrammed in the event that it is damaged or lost.
You can change the key fobs you own, but you must know the correct procedure. You must have these things to achieve the best results:
Keys
Most modern cars require a transponder key to operate. This is a security feature and anti-theft protection. These keys are programmed by a locksmith or authorized dealer to work with your car's systems and specific model. They are expensive to replace if lost, so you should keep extras handy. You can find replacement key fobs in online stores as well as many brick and mortar auto shops. How can you ensure that the one you bought is genuine? Do you know whether it has been programmed for another car or if it can be programmed to work with your car?
If you want to program a new key, the first step is to make sure that your car is running. Insert the key you wish to reprogram into the ignition without turning it. You only have a couple of seconds before the car's system resets the commands and leaves programming mode. Therefore, it is crucial to move quickly and not pause between steps. Shut off the engine to stop this. Change reprogram car key from "on" to "off" to test the system. The door locks should cycle and you'll hear a chime to indicate that the procedure was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to start the car. This technology is still vulnerable to a technique known as replay attacks that allows thieves to record the signal from the key fob of the car and then replicate it to open the car. To stop this, manufacturers introduced security features known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers also have special encryption on their key fobs which cannot be decoded by an ordinary program. These kinds of cars will need to be programmed by a professional. Therefore, you should only attempt this process if you have experience working with electronics. Refer to the manual for your car or go to the website of the manufacturer to find out how to program it. The steps are different according to the type of vehicle.
Transponder chips
Car keys with transponder chips need special programming to function. Any hardware store can offer you a new car key however the real challenge lies in implementing it to your car. The key you reprogrammed needs to be matched with the specific identification number of your vehicle, or it won't start the engine.
Transponder chips, which are used to stop theft of cars, are a common feature of modern cars. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car detects the signal, and starts the engine only if the signal is in line with the one programmed in the vehicle. The car will also shut down if a frequency is invalid. This makes it more difficult for novice car thieves to connect a vehicle with hot wires and start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is put in the ignition the magnetic field is created around the transponder. This creates a signal which is taken up by the coil and sent to the key identification number. The key's identification number is sent back to the car and the engine will start if the identification number matches.
There are many ways to program a key transponder, however all of them require the use of a specific tool. You can purchase these tools on the internet or at many automotive locksmiths. These tools aren't inexpensive, but they are vital for programming your car's chip.
You can also use an unreprogrammable key that was programmed for an alternative vehicle. In this case you'll need to make sure that the key is not damaged or that the transponder has been altered in any way. You can read the chip using a scanner, or a computer with the USB connector.
Reprogramming a transponder is a simple process, but requires special software. It also requires the use of a scanner. If you're just beginning you should seek the assistance of an auto locksmith. You should also avoid buying secondhand keys, as they're probably already programmed and will not work with your car.
EZ Installer
Prior to recently those who wanted to replace their key fob had to go to an agent to have it electronically linked to the vehicle. This is because in order to make modern keys work they have to be "paired". This required expensive and complex equipment that was available only to dealers. The EZ Installer by Car Keys Express simplifies the process of pairing modern keys to vehicles for retailers and locksmiths.
The EZ Installer, a simple "plug-and-play" OBD device, pairs new keys with vehicles without the use of complicated equipment or tokens to facilitate programming. It connects directly to the vehicle's standard OBD port and using a mobile app to provide simple-to-follow instructions. The EZ Installer works with most modern vehicles that include proximity keys or push-button start. To determine if it'll work with a specific vehicle, refer to the compatibility guidelines on Tom's site.
If the device is unable to program the remote or key purchased from Tom's into a compatible vehicle the full refund will be available.
In contrast to traditional programming equipment that costs key professionals thousands of dollars in typical per-key "token" charges, the EZ Installer Pro doesn't charge any fees and can be used as long as a retailer or key professional wishes to use it. The EZ Installer also eliminates the necessity for expensive monthly service contracts and updates, so it will reduce costs for retailers while providing customers with the same high-quality service as OEM equipment. It also offers a leading warranty that covers both hardware and software for the duration of your life.
