Reprogramming Car Keys
Transponder keys are believed to be more secure for cars and harder to copy by thieves. However, a key might require reprogramming if it becomes damaged or lost.
You can change the key fobs you own but you must be aware of the proper procedure. You should have these items to achieve the most effective results:
Keys
Most modern vehicles require some kind of transponder key or fob in order to work, which provides security and anti-theft protection. The keys are programmed by a locksmith or authorized dealer to work with the car's systems and the specific model. They are expensive to replace in the event of loss therefore, you should keep extras handy. You can purchase replacement key fobs in online stores as well as numerous brick-and-mortar auto shops. But how do you know that the one you purchased is authentic? Can you tell whether it has been programmed for a different vehicle or if it can be reprogrammed for yours?
To program a new car keys, first make sure that your car is running. Insert the key you wish to program into the ignition, but do not turn it. There are only a couple of seconds before the car's system reverts the commands and exits programming mode. For this reason, it is important to move quickly and not wait between steps. To avoid this happening, shut off the engine. You can test the car's system by turning the key to the "on" position and then back to the "off" position. There should be a chime signalling that the procedure was successful. The door locks will cycle.
Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to open the vehicle. This feature is still vulnerable to a technique dubbed a replay attack. It allows thieves to record and then reproduce the signal from the vehicle key fob to unlock the car. To combat this, manufacturers added security features known as the CAN bus protocols to prevent hacking.
Certain manufacturers also employ special encryption on their key fobs which cannot be decoded by a simple program. It is best to only attempt this method if you have experience is with electronics. It's a good idea to read the owner's manual of your vehicle or look up the manufacturer online, as the steps will differ depending on the car model.
Transponder chips
Car keys that feature transponder chips require a special reconfiguration to work. Any hardware store can offer you a new car key, but the real challenge lies in implementing it to your car. The key needs to be programmed to match the exact identification number of your vehicle, or else it won't start.
Transponder chips are a typical feature in modern cars and are designed to stop car theft. The chip is a microcircuit that transmits a radio frequency signal when the key is inserted in the ignition. The car detects the signal, and starts the engine only if it matches the one programmed into the vehicle. The vehicle is also programmed to stop if it detects an invalid frequency. This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and then start it.
A circuit board that has an induction coil connects the chip to the key. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This produces a signal which is absorbed by the coil, which sends 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 start.
There are several ways to program a key transponder, however all of them require a special tool. You can buy these tools online or from most automotive locksmiths. These tools are not inexpensive, but they are vital to program your car's chip.
You can also use an reprogrammable key that was previously programmed for a different vehicle. In this instance you'll need sure that the key has not been damaged or the transponder has been altered in any way. To accomplish this, you can use scanners or a computer with a USB port to scan the chip and determine its identity.
Reprogramming a transponder is a simple process, but requires specific software. It also requires the use of a scanner. It's best to ask an auto locksmith for help for those who are new to the process. Don't buy used keys since they could 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 other option than to go to a dealership to have their key electronically paired to the vehicle. This is because in order to make modern keys function they have to be "paired". This required expensive and complex equipment that was only available to dealers. The EZ Installer from Car Keys Express solves this issue for retailers and locksmiths by making it easier for pairing modern keys with vehicles.
The Easy Installer is a straightforward, "plug and play" OBD device that connects new keys to vehicles, without the need for expensive equipment or programming tokens. It works by connecting directly to the vehicle's standard OBD port, and then using an app for mobile devices to provide simple-to-follow instructions. The EZ Installer works with all newer vehicles that include proximity keys or push button start. To determine if it'll work for a particular vehicle, look up the compatibility guide on Tom's website.
If the device fails to program the remote or key purchased from Tom's into a compatible vehicle, a full refund is provided.
In contrast to traditional programming equipment, which can cost key professionals tens of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these fees. It is able to be used for as long as the key professional or retailer wants. The EZ Installer eliminates the need for costly monthly service contracts and software updates. This lets retailers save money while offering their customers the same top quality service as OEM equipment.
