Reprogramming Car Keys

Transponders in car keys are believed to make vehicles more secure and less likely to be duplicated by thieves. Keys may need to be reprogrammed in event of damage or lost.

You can reprogram your key fobs at home, however you must be aware of the proper procedure. For the best results, you must have the following items:

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 authorized dealer to work with the car's systems and the specific model. They are costly to replace if lost and you should keep extras handy. You can find key fobs to replace them in online stores as well as many brick-and mortar auto shops. How can you ensure that the key you purchased is genuine? Are you able to tell whether the unit is programmed to work with another vehicle or if it could 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 reprogramme into the ignition, but don't turn it. You only have a couple of seconds before the car's system resets the commands and exits programming mode. For this reason, it is important to move quickly and not be able to wait between steps. Stop the engine to avoid this. You can test the system of your car by turning the key to the "on" position and then back to the "off" position. You should hear a chime to indicate that the process was successful. The door locks will be able to cycle.

Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to start the car. The technology is still susceptible to a technique dubbed a replay attack 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 security features known as the CAN bus protocols to ward off hacking.

Certain manufacturers also have special encryption on their key fobs, that cannot be decoded with an easy program. You should only attempt this method if your previous experiences are with electronic devices. It is recommended to read the owner's manual of your vehicle or search for the manufacturer on the internet, since the steps will differ depending on the car model.

Transponder chips

Car keys with transponder chips require special reprogramming to work. While any hardware store can cut keys for you, the real issue is how to integrate it with your specific car. The key has to be programmed to match the exact identification number on your vehicle, or else it won't be able to start.

Transponder chips, which are used to prevent car theft are a standard feature of modern cars. The chip is a tiny microcircuit which transmits a radio-frequency signal when the ignition key is put in. The car is able to detect the signal and starts the engine only if the signal matches the original that was programmed into the vehicle. The car is also programmed so that it will stop if it detects an invalid frequency. This makes it more difficult for novice car thefts to hot-wire a vehicle and then turn it on.

The key and the chip are connected via 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, which is absorbed by the coil before being sent to the key's identification number. The key's identification number is sent back to the car and the engine is started when the identification number matches.

There are a variety of ways to program a transponder, but all of them require a special tool. You can purchase these tools online or at most locksmiths for cars. These tools are not expensive, but they are essential to program your car's chip.


You could also utilize a transponder that is reprogrammable that was previously programmed for a different vehicle. In this case you'll need to make sure that the key has not been damaged or the transponder been altered in any way. To accomplish this, you'll need scanners or a computer with a USB port to read the chip and determine its identity.

Reprogramming a transponder is a simple procedure, but requires special software. It also requires a scanner tool. It's best to ask an auto locksmith for help for those who are new to the process. Avoid buying used keys because they may already be programmed and will not work with your vehicle.
