Reprogramming Car Keys
Transponders in car keys are believed to make vehicles safer and are harder for thieves to duplicate. However, a key may require reprogramming when it becomes damaged or lost.
You can change the programming of your key fobs at home, but you should know the right process. For the best results you should have the following items:
Keys
Most modern vehicles require some kind of transponder key or fob in order to operate, providing security and protection against theft. These keys must be programmed to your particular vehicle and its systems by a licensed locksmith or dealer. They are costly to replace in the event of loss, so it is recommended to keep spare keys in the car. You can also find replacement keys fobs on various websites and in a variety of brick-and-mortar automotive shops. How can you be sure that the one you purchased is genuine? Do car key programing know whether it was programmed to work with another vehicle or if it is able to be reprogrammed for yours?
If you are planning to program a new key the first step is to ensure that your car is operating. Insert the key you wish to program into the ignition without turning it. You have just a few minutes before the system will reset all commands and leaves the programming mode. It is crucial to move quickly and do not wait between each step. Stop the engine to prevent this. You can test the system of your car by turning the key to the "on" position and then back to the "off" position. The door locks should cycle, and you'll hear a chime to indicate that the procedure was successful.
Certain vehicles of recent years use rolling keys to stop thieves from using stolen keys to start the car. The technology is still susceptible to a method known as replay attack, which allows thieves to record the signal of the key fob on the vehicle, then reproduce it to unlock the car. To stop this, manufacturers have added a security feature called the CAN bus protocol to prevent hacking attempts.
Some manufacturers use a special encryption on their keys that cannot be decoded using an ordinary program. It is best to only attempt this method if your previous experience is in electronics. Check the manual of your car or look up the manufacturer's website to find out how to program it. The steps will vary according to the type of vehicle.
Transponder chips
Car keys with transponder chips require a special reprogramming to function. Any hardware store can make you an entirely new car key, however the real challenge lies in making it work with your car. The key has to be programmed to match the exact identification code on your car, otherwise it won't start.
Transponder chips, used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the key is inserted in the ignition. The car then detects the signal and then starts the engine in case it matches the original one that was programmed into the vehicle. The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it more difficult for car thieves with no experience to hot wire a vehicle and start it.
A circuit board that has an induction coil connects the key to the chip. When the key is placed in the ignition it creates an electromagnetic field around the transponder. This produces a signal which is absorbed by the coil, which transmits it to the key's identification number. The key's identification number is sent back to the car and the engine will start when the identification number matches.
There are many ways to program a transponder key, however, they all require an instrument that is specifically designed for the purpose. You can buy these tools online or from most locksmiths for cars. These tools are not inexpensive, but they are vital for programming your car's chip.
You may also use a reprogrammable transponder key that has been previously programmed for another vehicle. In this instance you'll need to make sure that the key is not damaged or the transponder has been altered in any way. To accomplish this, you can use scanners or computers with an USB port to identify the chip and establish its identity.
Reprogramming the transponder is a straightforward process, but requires specialized software. It also requires a scanner tool. It is recommended to contact an auto locksmith for help if you're a novice. Also, avoid buying second-hand keys as they're likely to be programmed and won't work with your vehicle.
EZ Installer
Until recently those who wanted to replace their key fob were forced to visit a dealer to have it electronically linked to the vehicle. This is because modern keys have to be "paired" to a specific vehicle in order to work and work, which required expensive and complex equipment that only dealers could access. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys to vehicles for retailers and locksmiths.
The Easy Installer, a straightforward "plug-and-play" OBD device, pairs new keys with vehicles without the need for complex equipment or tokens for programming. It connects directly to the standard OBD port of the vehicle and utilizes a mobile application that provides easy-to-follow instructions. The EZ Installer is compatible with all modern vehicles with proximity keys or push-button start. To see if it will work for a particular vehicle, look up the compatibility guide on the Tom's website.
A full-money-back guarantee is provided if the device does not successfully program a remote or key purchased from Tom's for a vehicle that is compatible.
Contrary to conventional programming equipment which costs retailers and key professionals tens of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these fees. It is available for as long as the key professional or retailer wants. The EZ Installer eliminates the need for expensive 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 offers a leading warranty that covers both hardware and software for the duration of your life.
