Reprogramming Car Keys

Transponder keys are believed to be more secure for cars and are more difficult to copy by thieves. A key may have to be reprogrammed in the event of damage or lost.

You can reprogram your key fobs at home, but you must know the right process. You must have these things to ensure the best results:

Keys

Almost all modern cars require some kind of transponder fob or transponder keys to operate, providing security and protection against theft. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. It's costly to replace them if they become lost, so it's best to keep extras on hand. You can locate replacement key fobs in online stores and many brick-and mortar auto shops. How do you ensure that the key fob you bought is authentic? Are you able to tell if it has been programmed for a different vehicle or if it is able to be reprogrammed to fit your vehicle?

To program a new car key, you must first ensure that your car is running. Insert the key you want to reprogram into the ignition without turning it. You have just a few minutes before the system resets all commands and leaves the programming mode. This is why it is important to move quickly and not be able to wait between steps. To prevent this from happening, shut off the engine. Turn the key from "on" to "off" to test the system. You should hear a sound signalling that the procedure was successful. The door locks will go through a cycle.

Certain vehicles of recent years use rolling keys to stop thieves from using stolen keys to start the vehicle. This technology is still vulnerable to a technique known as a replay attack which allows thieves to record the signal from the key fob on the vehicle, then reproduce it to open the car. To counter this, manufacturers have added a security feature called CAN bus protocol to prevent attacks on hacking.

Some manufacturers use a special encryption on their keys, which cannot be decoded using an easy program. It is best to only attempt this process if your experience is in electronic devices. 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 special reprogramming in order to function. Any hardware store can offer you a new car key, but the real challenge lies in implementing it to your vehicle. The key you reprogrammed needs to be matched with the specific identification number of your vehicle otherwise it won't even start the engine.

Transponder chips, used to stop theft of cars are a standard feature of modern cars. The chip is a microcircuit that transmits a radio frequency signals when the key is placed into the ignition. The car detects the signal and begins the engine only if it matches the original one that was programmed in the vehicle. The car key programming and cutting also shuts down if a frequency is not valid. This makes it more difficult for thieves who are not experienced to wire a vehicle and then start it.

The chip and the key are connected by the circuit board which includes an induction coil. When the key is inserted into the ignition it creates an electric field around the transponder. This creates a signal that is amplified by the coil which transmits 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 begin to run.

There are many ways to program a transponder, but all require the use of a specific tool. These tools can be purchased through the internet or from many automotive locksmiths. These tools are not cheap but are essential to program your car's chip.

You can also use an reprogrammable key that was previously programmed for another vehicle. In this case, make sure the key has not been damaged or that the transponder is not altered in any way. You can read the chip by using a scanner or a computer equipped with a USB connector.

Reprogramming a transponder key is quite simple, however it requires an expertly designed software and scan tool. If you're just beginning, it's best to seek help from an auto locksmith. Avoid buying used keys because they could already be programmed, and they won't be compatible with your vehicle.

EZ Installer

Until recently those who wanted to replace their key fob were forced to visit an authorized dealer to get it electronically linked to the vehicle. It is because for modern keys to function they have 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 to vehicles for locksmiths and retailers.

A full money-back guarantee is offered in the event that the device fails to successfully program a remote or key purchased from Tom's for a vehicle compatible.

Contrary to conventional programming equipment which costs key retailers and professionals many thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these costs. It is available for as long as the key professional or retailer wants. The EZ Installer also eliminates the requirement for expensive monthly service agreements and updates, which means it will save retailers money while offering customers the same high-quality service as OEM equipment.
