Reprogramming Car Keys
Transponder keys are thought to be more secure for cars and harder to copy by thieves. However, a key might need to be reprogrammed if it becomes damaged or lost.
You can program key fobs yourself but you must be aware of the proper procedure. You should have these items to ensure the most effective results:
Keys
The majority of modern vehicles require a transponder key to operate. This provides security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with your car's system and specific model. They are expensive to replace in the event of loss, so it is recommended to keep spare keys in the car. You can find key fobs to replace them in online stores as well as numerous brick-and-mortar auto shops. But how do you know that the new one you purchased is authentic? Do you know whether the unit has been programmed to work with another vehicle or if it could be reprogrammed?
If you are planning to program an entirely new key first, you need to ensure that your car is on and running. Insert the key you'd like to program into the ignition, but do not turn it. You have only a few seconds left before the system will reset all commands and exits the programming mode. It is crucial to be quick and don't be patient between each step. Stop the engine to prevent this. Change the key from "on" to "off" to test the system. There should be car key programming indicating that the process was successful. The door locks will be able to cycle.
Some newer cars use a rolling key technology, which prevents thieves from using a stolen car's key to open it. The technology is still susceptible to a technique dubbed replay attacks that allows thieves to record the signal received from the key fob on the vehicle and then replicate it to open the car. To stop this, manufacturers have added security features known as the CAN bus protocols to stop hacking.
Certain manufacturers employ a specific encryption on their keys that cannot be decoded using a simple program. These kinds of cars require programming by a professional. Therefore, you should only try this with someone who has experience with electronics. It's a good idea to read the owner's manual for your car or look up the manufacturer online, as the steps will differ depending on the vehicle type.
Transponder chips
Car keys with transponder chips require a specific reprogramming to work. Any hardware store can make you a new car key, but the real challenge is in integrating it with your car. The key has to be programmed to match the exact identification number on your car, otherwise it won't 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 inserted. The car then recognizes the signal and then starts the engine in case it matches the original frequency that was programmed into the vehicle. The car also shuts down if the frequency is not valid. This makes it harder for thieves who aren't experienced to wire a vehicle hot and then start it.
A circuit board with an induction coil connects the chip to the key. When the key is put in the ignition the magnetic field is generated around the transponder. This generates a signal, which is received by the coil and sent to the key's identification. The key's identification number is transmitted back to the car and the engine will start if the identification number matches.
There are several methods to program a transponder key however, all require a special tool. These tools are available online or from most automotive locksmiths. These tools aren't cheap but are essential to program your car's chip.
You may also use a reprogrammable transponder key that has been previously programmed for another vehicle. In this instance, you'll need to make sure that the key is not damaged or the transponder has been altered in any way. To accomplish this, you can use scanners or a computer equipped with a USB port to read the chip and determine its identity.
The process of reprogramming a transponder key is quite easy, but it will require an expertly designed software and scan tool. It's best to ask an auto locksmith for assistance for those who are new to the process. Avoid buying used keys as they could already be programmed and will not work with your vehicle.
