Transponder keys are said to be more secure for cars and harder to copy by thieves. A key may have to be reprogrammed in event that it is damaged or lost.

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

Keys

Most modern cars require a transponder key to operate. This provides security and anti-theft protection. The keys have to be programmed to your particular vehicle and its systems by a certified locksmith or dealer. They are expensive to replace if lost and it is recommended to keep spare keys in the car. You can locate key fobs to replace them in online stores as well as many brick and mortar auto shops. How can you know that the one you bought is genuine? Are you able to tell if the unit has been programmed to work with another vehicle, or if it can be reprogrammed?

If you are planning to program an entirely new key, the first step is to ensure that your car is on and running. Insert the key you wish to program into the ignition, but do not turn it. You will only have a few seconds before the car's system reverts the commands and exits programming mode. For this reason, it is crucial to be quick and not wait between steps. Stop the engine to stop this. Change 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. The feature is still vulnerable to a technique known as a replay attack. It allows thieves to record and reproduce the signal from the vehicle key fob key programming to open the car. To stop this, manufacturers introduced the security feature known as the CAN bus protocols to ward off hacking.

Certain manufacturers employ a specific encryption on their keys, which cannot be decoded by a simple program. These types of vehicles require programming by a professional, so you should only try this with someone who has experience with electronic devices. Check the manual of your car or look up the website of the manufacturer to learn how to program it. The steps to follow will differ according to the type of vehicle.

Transponder chips

Car keys with transponder chips require special reconfiguration to work. Any hardware store can offer you an entirely new car key, but the real challenge lies in integrating it with your car. The key needs to be programmed to match the exact identification number of your vehicle, or else it will not start.

Transponder chips, used to stop theft of cars are a standard feature of modern cars. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is placed. The car is able to detect the signal and starts the engine only if the signal is in line with the one programmed in the vehicle. The car is also programmed to stop when it detects an incorrect frequency. This makes it more difficult for thieves with no experience to hot-wire a vehicle and then start it.

The chip and the key are connected via a circuit board that includes an induction coil. When the key is inserted into the ignition, it creates an electromagnetic field around the transponder. This produces a signal which gets amplified by the coil which transmits it to the key's identification number. The ID number of the key is sent back to the vehicle and if it matches the engine will begin to run.

There are several methods to program a key transponder, but all require a special tool. You can buy these tools on the internet or at many automotive locksmiths. They are not cheap, but they are essential for programming the chip to your vehicle.

You can also use an reprogrammable key that was previously programmed for an alternative vehicle. In this scenario, make sure that the key isn't damaged or that the transponder has not been altered in any way. You can read the chip using a scanner, or a computer with a USB connector.

Reprogramming an transponder is a simple process, but requires special software. It also requires the use of a scanner. It is recommended to contact an auto locksmith for help if you're a novice. Avoid buying used keys because they may already be programmed, and they won't work with your vehicle.
