Reprogramming Car Keys
Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. A key may have to be reprogrammed in case of damage or lost.
You can reprogram your key fobs at home, but you must be aware of the proper procedure. To get the best results, you must have the following items:
Keys
Most modern cars require a transponder key in order to operate. This is a security feature and anti-theft protection. These keys must be programmed to the specific car and its systems by a licensed dealer or locksmith. They are costly to replace in the event of loss therefore, you should have spares in your car. You will also find replacement key fobs on various websites and in a variety of brick-and-mortar automotive shops. How can you ensure that the one you bought is authentic? Are you able to tell whether the unit is programmed to work with a different vehicle or if yours can be reprogrammed?
If you want to program a new key, the first step is to ensure that your vehicle is on and running. Insert the key that you want to reprogramme into the ignition, but don't turn it. There are only a few seconds before the car's system resets the commands and leaves programming mode. It is essential to move quickly and don't delay between each step. Turn off the engine to avoid this. You can test the system of your car by turning the key to the "on" position, then back to the "off" position. The door locks should cycle, and you will hear a chime signalling that the process was successful.
Certain newer vehicles utilize rolling keys to stop thieves from using stolen keys to open the vehicle. The feature is still vulnerable to a technique called replay attack. It allows thieves to record and then reproduce the signal received from the key fob of the vehicle to open the car. To stop this, manufacturers have introduced a security feature called the CAN bus protocol to stop attacks on hacking.
Certain manufacturers have a unique encryption on their keys that cannot be decoded by an easy program. You should only attempt this process if your experience is with electronics. Consult your car's manual or go to the website of the manufacturer to find out how to program it. The steps will vary depending on the model of vehicle.
Transponder chips
Car keys with transponder chips need special reprogramming to work. While any hardware store can cut a new key for you, the main challenge is making it function to work with the specific car you own. The key must be programmed to match the exact identification code on your car, or else it won't start.
Transponder chips, used to protect cars from theft, are a common feature of modern automobiles. The chip is a microcircuit which emits a radio frequency signal when the key is inserted into the ignition. The car can detect the signal and starts the engine only if it matches the original one that was programmed into the vehicle. The car is also programmed so that it will stop when it detects an incompatible frequency. This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and then start it.
The chip and the key are connected via the circuit board which includes an induction coil. When the key is placed in the ignition, a magnetic field is created 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 transmitted back to the vehicle and if it is in line with the engine will begin to run.
There are a few different methods to program a transponder keys, however, they all require an instrument that is specifically designed for the purpose. You can purchase these tools online or at most locksmiths in the automotive industry. They are not cheap, but they are vital for programming the chip in your car.
You can also utilize a transponder that is reprogrammable that was previously programmed for another vehicle. In this instance, you must make sure the key isn't damaged or the transponder is not altered in any way. To do this, you can use scanners or a computer equipped with a USB port to identify the chip and establish its identity.
Reprogramming a transponder key is quite simple, however it requires specialized software and a scan tool. It's best to ask an auto locksmith for assistance for those who are new to the process. Don't buy used keys since they may already be programmed, and they won't work with your vehicle.
