Reprogramming Car Keys
Transponder keys are thought to be more secure for vehicles and more difficult to copy by thieves. The key could need to be programmed again in the case of damage or lost.
You can change the key fobs you own however, you must be aware of the correct procedure. You must have these things to ensure the best results:
Keys
Almost all modern cars require a transponder key or fob in order to operate, ensuring security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and the specific model. They can be costly to replace if they are lost therefore, you should have spares in your car. You will also find replacement key fobs at various online stores and in many brick-and-mortar auto shops. How do you ensure that the key fob you bought is authentic? Are you able to tell if it has been programmed to work with another vehicle or if it can be programmed to work with your car?
To program a new car key, you must first ensure that your car is running. Insert the key that you'd like to reprogramme into the ignition, but do not turn it. You will only have a couple of seconds before the car's system resets commands and leaves programming mode. This is why it is important to move quickly and not pause between steps. Turn off the engine to prevent this. You can check the system of your car by turning the key to the "on" position, then back to the "off" position. There should be a chime signalling that the procedure was successful. The door locks will cycle.
Certain newer vehicles have rolling key technology, which keeps thieves from using a stolen vehicle's key to open it. This feature is still vulnerable to a technique known as replay attack. It allows thieves to record and later reproduce the signal received from the vehicle key fob to unlock the car. To stop this, manufacturers have added a security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.
Certain manufacturers have a unique encryption on their keys, which can't be decoded with an easy program. You should only attempt this method if you have experiences are with electronics. Check the manual of your car or look up 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 require a special reprogramming to work. Any hardware store can make you an entirely new car key, but the real challenge lies in integrating it with your vehicle. The key you reprogrammed needs to be compatible with the specific identification number of your vehicle otherwise it won't even start the engine.
Transponder chips are a common feature of modern automobiles and are designed to guard against car theft. The chip is a microcircuit that emits a radio frequency signal when the key is inserted into the ignition. The car then scans for the signal and starts the engine if it matches the original signal that was programmed into the vehicle. The car is also programmed so that it will shut down when it detects an incorrect frequency. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.
A circuit board that has an induction coil that connects the chip to the key. When the key is inserted into the ignition it creates an electric field around the transponder. This generates a signal that gets amplified by the coil which then transmits it to key's identification number. The ID number of the key is then sent back to the vehicle and if it is in line with the engine will begin to run.
There are a variety of methods to program a key transponder, but all of them require a special tool. These tools can be purchased online or from most automotive locksmiths. These tools are not cheap but are essential for programming the chip in your car.
You can also use a reprogrammable transponder key that has been previously programmed for a different vehicle. In this instance, you must ensure that the key isn't damaged or that the transponder isn't altered in any way. To accomplish this, you can use scanners or computers with an USB port to read the chip and determine its identity.
Reprogramming an transponder's key is simple, but it requires specialized software and a scan tool. It's best to ask an auto locksmith for assistance in case you're not an expert. Avoid buying used keys as they might already be programmed, and they won't work with your car.
EZ Installer
For a long time, owners of cars who required a replacement for their key fob had no choice than to visit an auto dealer to have their key electronically paired to the vehicle. This is because modern keys need to be "paired" to a specific vehicle in order to function and work, which required the use of expensive and complicated equipment that only dealers could access. The EZ Installer by Car Keys Express simplifies the process of pairing modern keys with vehicles used by retailers and locksmiths.
