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 event of damage or lost.
You can change the programming of your key fobs at home, however you should be aware of the proper procedure. For the best results, you must have the following items:
Keys
Almost all modern cars require a transponder fob or transponder keys to work, which provides security and anti-theft protection. These keys must be programmed to your specific vehicle and its systems by a licensed locksmith or dealer. It's costly to replace them if they are lost, so it's better to have spares in your possession. You can locate key fobs to replace them in online stores, as well as many brick-and mortar auto shops. How can you ensure that the one you bought is genuine? Can you tell if the unit has been programmed to work with a different vehicle or if it could be reprogrammed?
To program a new car keys, first make sure that your vehicle is operating. Insert the key you want to reprogram into the ignition, but do not turn it. You have only a few seconds before the system resets all commands and then exits the programming mode. This is why it is crucial to be quick and not be able to wait between steps. To prevent this from happening, turn off the engine. You can check the car's system by turning the key to the "on" position, then back to the "off" position. The door locks should cycle, and you'll hear a chime signalling that the process was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the car. This feature is still vulnerable to a technique known as a replay attack that allows thieves to record the signal from the vehicle's key fob and reproduce it later to open the car. To counter this, manufacturers have added a security feature called the CAN bus protocol to thwart hacking attempts.
Certain manufacturers also employ special encryption on their key fobs, which are not decoded by a simple program. You should only attempt this method if you have experiences are with electronics. Check the manual of your car or visit the website of the manufacturer for information on how to program it. The steps will vary depending on the type of vehicle.
Transponder chips
Transponder chip car keys require a special reprogramming to work. While any hardware store can cut keys for you, the biggest problem is to make it work in conjunction with your particular car. A key that has been reprogrammed will need to match the specific identification number of your vehicle otherwise it won't even start the engine.
Transponder chips are a standard feature of modern cars and are designed to guard against car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is inserted in the ignition. The car detects the signal and starts the engine only if the signal is in line with the original one that was programmed into the vehicle. The car will also shut down if the frequency is not valid. This makes it much harder for thieves who are not experienced to hot wire a vehicle and then start it.
The key and the chip are linked by an electronic circuit board that contains an induction coil. When the key is inserted into the ignition it creates an electric field around the transponder. This generates a signal that gets absorbed by the coil, which sends it to the key's identification number. The ID number of the key is transmitted back to the vehicle, and if it matches, the engine will start.
There are several methods to program a transponder keys, but they all involve using an instrument that is specifically designed for the purpose. You can buy these tools online or from most automotive locksmiths. These tools aren't expensive, but they are essential to program your car's chip.
You can also use an reprogrammable key that was previously programmed for an alternative vehicle. In this scenario you'll need to make sure that the key isn't damaged or the transponder been altered in any way. You can read the chip using a scanner, or a computer that has an USB connector.
Reprogramming an transponder is a simple procedure, but requires specific software. It also requires the use of a scanner. It is recommended to contact an auto locksmith for help if you're a novice. You should also avoid buying second-hand keys, since they are likely already programmed and will not be compatible with your car.
EZ Installer
For a long time, owners of cars who required replacement of their key fob had no other option than to go to a dealership to have their key linked to their vehicle. It is because to make modern keys function they have to be "paired". This required expensive and complex equipment that was only available to dealers. The EZ Installer from Car Keys Express solves this issue for retailers and locksmiths by easing the process of connecting modern keys to vehicles.

It connects directly to the standard OBD port of the vehicle and utilizes an app that can be downloaded on mobile devices to provide easy to follow instructions. The EZ Installer works with all newer models that have proximity keys or push button start. Go to the compatibility guide on Tom's website to determine whether your vehicle is compatible.
If the device is unable to program the remote or key purchased from Tom's into a compatible vehicle the full refund will be offered.
Unlike traditional 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 able to be used for as long as the key professional or retailer wants. The EZ Installer also eliminates the necessity for expensive monthly service agreements and updates, which means it can save retailers money while still providing customers with the same high-quality service as OEM equipment. It also comes with an industry-leading warranty that covers all hardware and software for life.
