Reprogramming Car Keys
Transponder keys are believed to be more secure for cars and are more difficult to copy by thieves. The key could need to be reprogrammed in case of damage or lost.
You can reprogram your key fobs at home, but you should be aware of the correct procedure. It is essential to have these items to achieve the most effective results:
Keys
Most modern cars require a transponder keys to operate. This gives security and anti-theft protection. These keys must be programmed to your particular vehicle and its systems by a licensed dealer or locksmith. They can be costly to replace if they are lost and 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 ensure that the one you bought is genuine? Are you able to tell whether the unit has been programmed to work with a different vehicle or if it could be programmed differently?
If you are planning to program a new key the first step is to make sure that your car is on and running. Insert the key you wish to reprogram into the ignition without turning it. You have only a few seconds before the system will reset all commands and then exits the programming mode. It is essential to be quick and don't wait between each step. Stop the engine to avoid this. You can test the car's security system 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 process has been successful.
Certain cars with more modern technology have rolling key technology, which prevents thieves from using stolen cars' key to start it. This feature is still vulnerable to a technique known as a replay attack. It allows thieves to record and reproduce the signal received from the key fob of the vehicle to unlock the car. To stop this, manufacturers have added a security feature called CAN bus protocol to prevent attacks on hacking.
Certain manufacturers have a unique encryption on their keys that can't be decoded with an ordinary program. These types of vehicles will need to be programmed by a professional. Therefore, you should only try this with someone who has experience with electronics. Consult your car's manual or visit the website of the manufacturer to find out how to program it. The steps are different depending on the type of vehicle.
Transponder chips
Car keys that feature transponder chips need special reconfiguration to work. While any hardware store can cut a new key for you, the main problem is to make it work to work with the specific car you own. The key needs to be programmed to match the exact identification number of your car, otherwise it won't start.
Transponder chips, used to protect cars from theft, are a common feature of modern cars. The chip is a microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car then detects the signal and begins the engine if it is in line with the original one that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it more difficult for novice car thefts to connect a vehicle to a hot wire and then turn it on.
The chip and the key are linked by a circuit board that includes an induction coil. When the key is placed in the ignition it creates an electric field around the transponder. This generates a signal, which is absorbed by the coil before being sent to the key's identification. The key's identification number is returned to the car and the engine will start if the identification number matches.
There are a variety of ways to program a transponder, but all require a special tool. These tools are available online or from most automotive locksmiths. These tools aren't cheap but are essential for programming the chip in your car.
You could also use a unreprogrammable key that was programmed for a different vehicle. In this scenario, make sure the key hasn't been damaged or the transponder isn't altered in any way. You can read the chip with a scanner, or a computer with an USB connector.
Reprogramming a transponder is a simple procedure, but requires special software. It also requires an scanner tool. It's best to ask an auto locksmith for assistance for those who are new to the process. Avoid buying used keys because they might already be programmed and will not be compatible with your vehicle.
EZ Installer
Prior to recently those who wanted to replace their key fob were forced to go to an authorized dealer to get it digitally paired to the vehicle. It is because to make modern keys function they must 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 with vehicles used by 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 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 a wide range of modern vehicles with proximity keys or push-button start. Visit the compatibility guide on Tom's site to see if your vehicle is compatible.
If the device is unable to program a remote or key purchased from Tom's into a vehicle compatible the full refund will be offered.
Contrary to conventional programming equipment that costs retailers and key professionals thousands of dollars in typical per-key "token" costs, the EZ Installer Pro doesn't charge any fees and can be used for as long as a key professional would like it to be. The EZ Installer eliminates the need for costly monthly service contracts and software updates. This allows retailers to save money while giving their customers the same top quality service as OEM equipment. It also offers a top warranty that covers both hardware and software for the rest of your life.
Tools
Locksmiths, auto mechanics and owners of vehicles can utilize car key programming tools to program new keys for vehicles. These tools communicate with the vehicle's immobilizer system to create new keys and remote controls. They can also be used to copy existing keys and create duplicate keys. These tools are a valuable tool for those who own a car.
