Reprogramming Car Keys
Transponders in car keys are believed to make vehicles safer and are harder for thieves to duplicate. However, a key may need to be reprogrammed when it becomes damaged or lost.
You can change the key fobs you own, but you must know the proper procedure. It is essential to have these items to ensure the best results:
Keys
Nearly all modern vehicles require a transponder key or fob in order to work, which provides security and protection against theft. These keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. They can be costly to replace if lost, so you should have spares in your car. You can find key fobs to replace them in online stores, as well as many brick and mortar auto shops. But how can you tell that the new one you purchased is authentic? Are you able to tell whether it has been programmed for another car or if it can be reprogrammed for yours?
If you want to program a new key first, you need to ensure that your vehicle is running. Insert the key you want to reprogram into the ignition without turning it. There are only a few seconds before the car's system reverts the commands and leaves programming mode. For this reason, it is important to be quick and not wait between steps. Stop the engine to stop this. You can test the car's security system by turning the key to the "on" position and back to the "off" position. There should be a chime indicating that the process was successful. The door locks will cycle.
Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to open the vehicle. This feature is still susceptible to a technique dubbed a replay attack. It allows thieves to record and reproduce the signal from the vehicle key fob to open the car. To counter this, manufacturers have added an additional security feature known as the CAN bus protocol to stop attacks on hacking.
Some manufacturers use a special encryption on their keys that can't be decoded with an ordinary program. It is best to only attempt this process if your experience is with electronics. It is a good idea to consult the owner's manual of your vehicle or look up the manufacturer online, as the steps differ based on vehicle type.
Transponder chips
Transponder chip car keys require a special reprogramming to work. While any hardware store can cut keys for you, the biggest issue is how to integrate it with your specific car. A reprogrammed key will need to be matched with the exact identification number of your car otherwise it won't even start the engine.
Transponder chips, used to stop theft of cars, are a common feature of modern automobiles. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is placed. The car then recognizes the signal and then starts the engine if it is in line with the original one that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it harder for thieves who aren't experienced to hot-wire a vehicle and then turn it on.
A circuit board equipped with an induction coil that connects the chip to the key. When the key is put in the ignition it creates a magnetic field created around the transponder. This generates a signal that is absorbed by the coil before being sent to the key's identification. The ID number of the key is then sent back to the vehicle and if it matches the engine will start.
There are a variety of methods to program a key transponder, however 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 are not cheap, but they are vital for programming the chip in your vehicle.
You can also utilize a transponder that is reprogrammable that was previously programmed for another vehicle. In this case, ensure that the key has not been damaged or that the transponder isn't altered in any way. To check this, you'll need scanners or a computer equipped with a USB port to read the chip and determine its identity.
Reprogramming a transponder key is quite simple, but it requires an expertly designed software and scan tool. If you're just beginning, it's best to seek help from an auto locksmith. Also, avoid buying second-hand keys, since they are likely already programmed and will not work with your car.
EZ Installer
For a long time, car owners who required a replacement for their key fob had no other alternative than to visit a dealership to have their key electronically linked to their vehicle. This is because, in order 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 for locksmiths and retailers.
The Easy Installer, a straightforward "plug-and-play" OBD device, pairs new keys with vehicles without the use of complex equipment or tokens for 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 is compatible with most newer vehicles that have proximity keys or push button start. To see if it will work for a particular vehicle, check the compatibility guide on the Tom's website.
If the device is unable to program the remote or key purchased from Tom's into a compatible vehicle then a full refund is available.
Unlike traditional programming equipment that costs key professionals thousands of dollars through typical per-key "token" costs, the EZ Installer Pro doesn't charge any fees which means it can be used as long as a key professional wishes to use it. The EZ Installer eliminates the need for costly monthly service contracts and software updates. This allows retailers to save money while providing their customers the same high-quality service as OEM equipment. It also comes with a renowned warranty that covers hardware and software for the duration of your life.
