Reprogramming Car Keys
Transponder keys are said to be more secure for vehicles and more difficult to copy by thieves. Keys may need to be programmed again in the event of damage or lost.
You can program key fobs yourself but you must be aware of the correct process. You must have these things to achieve the most effective results:
Keys
The majority of modern vehicles require a transponder key to operate. This is a security feature and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. They are costly to replace if they are lost therefore, you should have spares in your car keys programmed. You will also find replacement key fobs at various online stores and in a variety of brick-and-mortar automotive shops. How do you ensure that the one you have bought is authentic? Do you know whether it was programmed to work with another vehicle or if it is able to be programmed to work with your car?
To program a new car key first make sure that your car is running. Insert the key that you'd like to reprogramme into your ignition, but do not turn it. There are only a few seconds left before the system will reset all commands and leaves the programming mode. It is important that you be quick and don't wait between each step. Shut off the engine to avoid this. Switch the key from "on" to "off" to test the system. You should hear a sound to indicate that the process was successful. The door locks will cycle.
Some newer cars use a rolling key technology, which keeps thieves from using a stolen car's key to open it. This feature is still susceptible to a technique dubbed replay attack. It allows thieves to record and then reproduce the signal from the car key fob to open the car. To prevent this, manufacturers have introduced a security feature called CAN bus protocol to prevent hacking attempts.
Certain manufacturers employ a specific encryption on their keys that cannot be decoded using a simple program. It is best to only attempt this method if you have experience is with electronic devices. Check the manual of your car or look up the website of the manufacturer to find out how to program it. The steps will vary depending on the model of vehicle.
Transponder chips
Transponder chip car keys require a specific reprogramming to function. While any hardware store can cut keys for you, the real problem is to make it work in conjunction with your particular car. The key needs to be programmed to match the exact identification number of your car, otherwise it will not start.
Transponder chips, used to prevent car theft are a standard feature of modern cars. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted into the ignition. The car can detect the signal and begins the engine only if the signal is in line with the original one that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it harder for thieves with no experience to wire a vehicle hot and then start it.
A circuit board that has an induction coil connects the chip to the key. When the key is placed in the ignition, it creates an electromagnetic field around the transponder. This creates a signal that is taken up by the coil, which then transmits it to key's identification number. 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 ways to program a key transponder, however each requires the use of a specific tool. You can buy these tools online or at most automotive locksmiths. These tools aren't cheap but are essential to program your car's chip.
You can also make use of a transponder key that can be reprogrammed that was previously programmed for another vehicle. In this case, make sure the key has not been damaged or that the transponder isn't altered in any way. To accomplish this, you'll need scanners or a computer with an USB port to scan the chip and determine its identity.
The process of reprogramming a transponder key is quite simple, but it requires special software and a scanning tool. It's best to ask an auto locksmith for help if you're a novice. Avoid buying used keys because they might already be programmed and won't work with your vehicle.
EZ Installer
For a long time, owners of cars who needed to replace their key fob had no option than to go to a dealership to get their key paired to the vehicle. It is because to make modern keys work, 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 used by locksmiths and retailers.
The EZ Installer, a basic "plug-and-play" OBD device, connects new keys to vehicles without the use of complicated equipment or tokens to facilitate programming. It works by connecting directly to the vehicle's standard OBD port and using an app on mobile key programming devices to provide simple-to-follow instructions. The EZ Installer is compatible with most newer vehicles that have proximity keys or push button start. Check the compatibility guide at Tom's website to determine if your vehicle is compatible.
If the device is unable to program a remote or key purchased from Tom's into a vehicle that is compatible, a full refund is provided.

It is available for as long as a key professional or retailer needs. The EZ Installer eliminates the need for costly monthly service contracts and software updates. This lets retailers save money while providing their customers the same high-quality service as OEM equipment.
