Reprogramming Car Keys
Car keys with transponders are believed to make vehicles safer and are more difficult for thieves to duplicate. Keys may need to be reprogrammed in the event of damage or lost.
You can change the key fobs you own but you must be aware of the correct process. To get the best results, you'll need the following items:
Keys
Most modern vehicles require some kind of transponder key or fob in order to operate, providing security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with the car's systems and specific model. They are expensive to replace if they are lost and it is recommended to keep spare keys in the car. 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? Do you know if the unit has been programmed to work with another vehicle or if yours can be reprogrammed?
If you want to program a new key first, you need to ensure that your vehicle is on and running. Insert the key you wish to reprogram into the ignition without turning it. There are only just a few seconds before the car's system resets commands and then exits programming mode. This is why it is important to move fast and not be able to wait between steps. To avoid this happening, turn off the engine. Turn the key from "on" to "off" to test the system. The door locks should be able to cycle, and you'll hear a chime signalling that the process has been successful.
Certain cars with more modern technology have rolling key technology, which prevents thieves from using stolen cars' key to open it. This technology is still vulnerable to a method known as replay attack which allows thieves to record the signal from the vehicle's key fob and then replicate it to unlock the car. To combat this, manufacturers added a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Some manufacturers use a special encryption on their keys, which cannot be decoded using a simple program. These types of cars will need to be programmed by a professional, so you should only attempt this procedure with someone who has experience with electronic devices. It is a good idea to read the owner's manual of your vehicle or search for the manufacturer on the internet, since these steps vary by vehicle type.
Transponder chips
Transponder chip car keys require a specific reprogramming to function. Any hardware store can give you an entirely new car key, however the real challenge lies in making it work with your car. The key you reprogrammed needs to be compatible with the specific identification number of your car, or it won't start the engine.
Transponder chips are a typical feature of modern cars and are designed to guard against car theft. The chip is a microcircuit that transmits a radio frequency signals when the key is placed into the ignition. The car can detect the signal and starts the engine only if the signal is in line with the original that was programmed in the vehicle. The car also shuts down if a frequency is invalid. This makes it more difficult for novice car thieves to hot wire a vehicle and start it.
The key and the chip are connected 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 produces a signal which is absorbed by the coil, which transmits it to the key's identification number. The key's ID number is then sent back to the vehicle, and if it matches the engine will start.
There are several methods to program a key transponder, but each requires the use of a specific tool. You can buy these tools on the internet or at many locksmiths for cars. These tools aren't cheap but are essential to program your car's chip.
You may also use a reprogrammable transponder key that has been previously programmed for another vehicle. In this scenario, 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 with a scanner, or a computer with an USB connector.
Reprogramming an transponder is a simple process, but requires specialized software. It also requires an scanner tool. If you're just beginning, it's best to seek out the help of an auto locksmith. You should also avoid buying second-hand keys as they're probably already programmed and will not be compatible with your car.
EZ Installer
For decades, car owners who needed to replace their key fob had no option than to go to a dealership to have their key electronically linked to their vehicle. It is because to make modern keys function, they need to be "paired". This required expensive and complicated equipment that was available only to dealers. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys with vehicles for locksmiths and retailers.
The EZ Installer is a simple, "plug and play" OBD device that pairs new keys with vehicles without the need for complex equipment or programming tokens. It works by connecting directly to the vehicle's standard OBD port and utilizing an app for mobile devices to provide simple-to-follow instructions. The EZ Installer is compatible with the majority of newer models, including those with proximity keys or push button start. Visit the compatibility guide on Tom's site to see if your vehicle is compatible.
A full-money-back guarantee is provided if the device does not successfully program a key or remote purchased from Tom's for a compatible vehicle.
Unlike car key programming that can cost retailers and key professionals thousands of dollars through typical per-key "token" charges, the EZ Installer Pro doesn't charge any fees and can be used for as long as a key professional wishes it to be. The EZ Installer also eliminates the need for costly monthly service contracts and updates, so it will reduce costs for retailers while offering customers 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.
