Reprogramming Car Keys
Transponder keys for car keys are believed to make vehicles safer and are harder for thieves to duplicate. However, key programing might need to be reset if it becomes damaged or lost.
You can reprogram your key fobs at home, however you need to be aware of the correct procedure. It is essential to have these items to ensure the best results:
Keys
Almost all modern cars require some kind of transponder fob or transponder keys to operate, providing security and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to work with your car's system and specific model. It's costly to replace them if they're lost, so it's better to have spares in your possession. You can find key fobs to replace them in online stores and numerous brick-and-mortar auto shops. How can you be sure that the one you bought is authentic? Are you able to tell whether it was programmed to work with another vehicle or if it could be programmed to work with your car?
To program a new car key you must first ensure that your car is running. Insert the key you wish to program into the ignition, but don't turn it. You have just a few minutes before the system will reset all commands and leaves the programming mode. This is why it is important to move quickly and not pause between steps. To prevent this from happening, turn off the engine. Switch the key from "on" to "off" to test the system. You should hear a chime signalling that the procedure was successful. The door locks will go through a cycle.
Some newer cars use a rolling key technology that stops thieves from using a stolen vehicle's key to start it. This feature is still vulnerable to a technique known as a replay attack, which allows thieves to record the signal from the key fob of the car and reproduce it later to unlock the car. To prevent this, manufacturers have added a security feature known as the CAN bus protocols to stop hackers from gaining access to the vehicle.
Certain manufacturers employ a specific encryption on their keys that can't be decoded with an easy program. You should only try this process if your experience is with electronics. It is a good idea to refer to the owner's manual of your vehicle or search for the manufacturer online, as the steps will differ depending on the vehicle model.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut a new key for you, the main challenge is making it function in conjunction with your particular car. A key that has been reprogrammed will need to match the specific identification number of the vehicle, or it won't start the engine.
Transponder chips are a common feature of modern cars and are designed to stop car theft. The chip is a microcircuit that emits a radio frequency signal when the key is placed into the ignition. The car is able to detect the signal and begins the engine only if the signal is in line with the one programmed in the vehicle. The car will also shut down if the frequency is invalid. This makes it difficult for novice car thefts to wire a vehicle hot and then start it.
A circuit board equipped with an induction coil that connects the key to the chip. When the key is inserted into the ignition it creates an electric field around the transponder. This creates a signal which is received by the coil before being sent to the key identification number. The ID number of the key is transmitted back to the vehicle, and if it is in line with the engine will begin to run.
There are a few different ways to program a transponder key however, they all require an appropriate tool. These tools can be bought through the internet or from many automotive locksmiths. They're not cheap, but they're vital for programming the chip to your vehicle.
You may also use a reprogrammable key that was previously programmed for another vehicle. In this instance, you must ensure that the key hasn't been damaged or the transponder has not been altered in any way. To do this, you'll need a scanner or a computer equipped with a USB port to scan the chip and determine its identity.
Reprogramming an transponder is a simple process, but requires specific software. It also requires the use of a scanner. If you're just beginning you should seek out the help of an auto locksmith. Don't buy used keys since they might already be programmed and won't be compatible with your vehicle.
EZ Installer
For a long time, owners of cars who required a replacement for their key fob had no option than to go to an auto dealer to have their key connected to the vehicle. This is because modern keys have to be "paired" to the vehicle of the owner in order to function and work, which required the use of expensive and complicated equipment that only dealers could access. The EZ Installer by Car Keys Express simplifies the process of pairing up modern keys with vehicles used by retailers and locksmiths.
The EZ Installer is a simple, "plug and play" OBD device that pairs new keys to vehicles, without the need for complicated equipment or programming tokens. It connects directly to the standard OBD port on the vehicle, and runs 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. Go to the compatibility guide on Tom's site to see if your vehicle is compatible.
If the device fails to program a remote or a key purchased from Tom's into a vehicle compatible, a full refund is offered.
Unlike traditional programming equipment that can cost retailers and key professionals thousands of dollars through typical per-key "token" fees, the EZ Installer Pro doesn't charge any fees, so it can be used as long as a retailer or key professional wants to use it. The EZ Installer eliminates the need for costly monthly service contracts and software updates. This lets retailers save money while offering their customers the same high-quality service as OEM equipment. It also comes with a renowned warranty that covers both hardware and software for the remainder of your life.
