Reprogramming Car Keys
Car keys with transponders are believed to make vehicles safer and are more difficult for thieves to duplicate. The key could need to be reprogrammed in the event of damage or lost.
You can change the key fobs you own but you must be aware of the correct procedure. It is essential to have these items to get the most effective results:
Keys
Almost all modern cars require a transponder fob or transponder keys to work, which provides security and protection against theft. These keys must be programmed to your particular vehicle and its systems by an authorized dealer or locksmith. It's expensive to replace them if they become lost, so it's better to keep extras on hand. You will also find replacement key fobs in various online stores and in many brick-and mortar auto shops. How can you ensure that the key you purchased is genuine? Are you able to tell whether the unit is programmed to work with a different vehicle, or if it can be reprogrammed?
If you're looking to program an entirely new key the first step is to ensure that your vehicle is running. Insert the key you want to program into the ignition, but do not turn it. There are just a few minutes before the system resets all commands and exits the programming mode. It is important that you be quick and don't delay between each step. To avoid this happening, turn off the engine. You can check the car's security system by turning the key to the "on" position, then back to the "off" position. The door locks should be able to cycle, and you'll hear a sound that indicates that the process was successful.
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 method known as replay attacks that allows thieves to record the signal from the vehicle's key fob and then replicate it to unlock the car. To prevent this, manufacturers have introduced an additional security feature known as the CAN bus protocol to thwart attacks on hacking.
Certain manufacturers also have special encryption on their key fobs which are not decoded by a simple program. You should only try this process if your experiences are with electronic devices. Check the manual of your car or visit the website of the manufacturer for information on how to program it. The steps to follow will differ according to the type of vehicle.
Transponder chips
Car keys with transponder chips require a special reprogramming to work. While any hardware store can cut keys for you, the main issue is how to integrate it with your specific car. The key needs to be programmed to match the exact identification code on your car, otherwise it will not start.
Transponder chips are a standard feature of modern automobiles and are designed to prevent car theft. The chip is a microcircuit which transmits a radio frequency signal when the key is inserted into the ignition. The car detects the signal and begins the engine only if the signal is in line with the one programmed into the vehicle. The car will also shut down if a frequency is invalid. This makes it difficult for novice car thefts to hot-wire a vehicle and then start it.
The chip and the key are linked by the circuit board which includes an induction coil. When the key is put in the ignition it creates a magnetic field created around the transponder. This produces a signal which gets absorbed by the coil, which sends it to the key's identification number. The key's identification code is returned to the car, and the engine starts if the identification number matches.
There are many ways to program a transponder keys, however, they all require an instrument that is specifically designed for the purpose. You can buy these tools on the internet or at many locksmiths for cars. They are not cheap, but they're vital for programming the chip to your vehicle.
You could also use a resettable key that was programmed for a different vehicle. In this scenario, ensure that the key isn't damaged or the transponder has not been altered in any way. The chip can be read with a scanner, or a computer that has a USB connector.
The process of reprogramming the transponder key is simple, but it requires special software and a scanning tool. If you're a beginner it is recommended to seek help from an auto locksmith. Avoid buying used keys because they might already be programmed, and they won't work with your car.
EZ Installer
For decades, car owners who required a replacement for their key fob had no other option than to go to a dealer to get their key connected to the vehicle. This is because modern keys need to be "paired" to the vehicle of the owner in order to work in a way that required the use of expensive and complicated equipment that only dealers could access. The EZ Installer from Car Keys Express solves this issue for locksmiths and retailers by making it easier for pairing modern keys with vehicles.
The EZ Installer, a basic "plug-and-play" OBD device, pairs new keys with vehicles without the use of complex equipment or tokens for programming. It connects directly to the vehicle's standard OBD port and using an app for mobile devices to provide simple-to-follow instructions. The EZ Installer is compatible with the majority of newer models that include proximity keys or push button start. Go to the compatibility guide on Tom's website to see if your vehicle is compatible.
A full money-back guarantee is offered in the event that the device cannot successfully program a key or remote purchased from Tom's for a compatible vehicle.
Unlike traditional programming equipment that costs key professionals thousands of dollars with typical per-key "token" charges, the EZ Installer Pro doesn't charge any fees which means it can be used as long as a key professional wants to use it. The EZ Installer also eliminates the requirement for expensive monthly service agreements and updates, which means it could save retailers money while providing the same quality service as OEM equipment. It also offers a leading warranty that covers hardware and software for the remainder of your life.
