Reprogramming Car Keys

Transponder keys for car keys are thought to keep vehicles safer and are less likely to be duplicated by thieves. However, a key may need to be reprogrammed if it becomes damaged or lost.

You can reprogram key fobs yourself, but you must know the proper procedure. For the best results, you must have the following items:

Keys

Modern cars require a transponder key to operate. This is a security feature and anti-theft protection. These keys are programmed by a locksmith or authorized dealer to work with the car's systems and the specific model. It's expensive to replace them if they become lost, so it's a good idea to have spares available. You can also find replacement keys fobs on various websites and in many brick-and-mortar auto shops. How can you know that the one you purchased is authentic? Can you tell whether the unit is programmed to work with a different vehicle, or if it can be programmed differently?

To program a new car key, you must first verify that your vehicle is running. Insert the key you'd like to program into the ignition, but don't turn it. There are just a few minutes before the system resets all commands and exits the programming mode. Therefore, it is important to move quickly and not pause between steps. To avoid this happening, shut off the engine. You can check the car's system by turning the key to the "on" position and then back to the "off" position. The door locks should cycle, and you'll hear a sound that indicates that the process was successful.

Certain cars with more modern technology have rolling key technology that prevents thieves from using stolen cars' key to open it. This feature is still vulnerable to a technique dubbed replay attacks that allows thieves to record the signal from the key fob on the vehicle, then reproduce it to unlock the car. To combat this, manufacturers have added the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.

Certain manufacturers employ a specific encryption on their keys that can't be decoded with an ordinary program. You should only try this method if your previous experience is with electronic devices. Check the manual of your car or go to the website of the manufacturer for information on how to program it. The steps to follow will differ depending on the model of vehicle.

Transponder chips

Car keys that feature transponder chips require special programming to function. Any hardware store can make you an entirely new car key, however the real challenge lies in implementing it to your vehicle. The key must be programmed to match the exact identification code on your car, or else it will not start.

Transponder chips are a common feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit which transmits a radio frequency signals when the key is inserted in the ignition. The car detects the signal and begins the engine only if the signal is in line with the original that was programmed in the vehicle. The car is also programmed so that it will stop when it detects an incorrect frequency. This makes it difficult for novice car thefts to connect a vehicle to a hot wire and then turn it on.

A circuit board equipped with an induction coil connects the chip to the key. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This creates a signal which is received by the coil and sent to the key reprogramming's identification number. The key's ID number is sent back to the vehicle, and if it matches, the engine will begin to run.

There are a variety of ways to program a key transponder, however all require an instrument that is specifically designed for. You can buy these tools on the internet or at many automotive locksmiths. These tools aren't inexpensive, but they are vital for programming the chip in your car.

You can also use a reprogrammable transponder key that was previously programmed for another vehicle. In this case, you'll need to make sure that the key is not damaged or the transponder been altered in any way. To accomplish this, you can use scanners or computers equipped with an USB port to scan the chip and determine its identity.

Reprogramming a transponder is a simple procedure, but requires specific software. It also requires a scanner tool. If you're new to the process it is recommended to seek the assistance of an auto locksmith. Don't buy used keys since they could already be programmed and will not work with your vehicle.
