Why We Love Reprogramming Car Key (And You Should Also!)
Reprogramming Car Keys

Car keys with transponders are thought to keep vehicles safer and are more difficult for thieves to duplicate. However, a key might need to be reset when it becomes damaged or lost.

You can change the key fobs you own but you must be aware of the correct procedure. To get the best results, you must have the following items:

Keys

Most modern cars require a transponder key to operate. This gives security and protection against theft. These keys must be programmed to the specific car and its systems by a certified dealer or locksmith. They are costly to replace in the event of loss therefore, it is recommended to keep spare keys in the car. You can also find replacement keys fobs in various online stores and in a variety of brick-and-mortar automotive shops. How can you be sure that the one you purchased is authentic? Do you know if the unit has been programmed to work with another vehicle or if yours can be programmed again?

If you're looking to program a new key first, you need to ensure that your vehicle is on and running. Insert the key you want to reprogram into the ignition without turning it. There are only a couple of seconds before the car's system resets the commands and then exits programming mode. It is crucial to move quickly and don't be patient between each step. Shut off the engine to prevent this. You can test the car's system by turning the key to the "on" position, then back to the "off" position. You should hear a sound indicating that the process was successful. The door locks will cycle.

Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the vehicle. This technology is still vulnerable to a technique dubbed a replay attack that allows thieves to record the signal from the key fob on the vehicle, then reproduce it to unlock the car. To prevent this, manufacturers have added the security feature known as the CAN bus protocols to prevent hacking.

Certain manufacturers have a unique encryption on their keys, which cannot be decoded by a simple program. You should only try this method if you have experience is in electronics. Consult your car's manual or look up the website of the manufacturer to find out how to program it. The steps are different depending on the model of vehicle.

Transponder chips

Car keys with transponder chips require a special programming to function. Any hardware store can give you an entirely new car key, however the real challenge lies in making it work with your car. The key needs to be programmed to match the exact identification number on your car, or else it will not start.

Transponder chips are a common feature of modern automobiles and are designed to guard against car theft. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is placed. The car then scans for the signal and begins the engine in case it matches the original signal that was programmed into the vehicle. The car is also programmed to stop if it detects an invalid frequency. This makes it harder for thieves with no experience to connect a vehicle to a hot wire and then turn it on.

The chip and the key are connected by an electronic circuit board that contains an induction coil. When the key is put in the ignition, a magnetic field is generated around the transponder. This generates a signal that is received by the coil and sent to the key identification number. The key's identification number is then transmitted back to the car, and the engine starts when the identification number matches.

There are several methods to program a key transponder, but all require an instrument that is specifically designed for. These tools are available through the internet or from many automotive locksmiths. These tools aren't expensive, but they are essential to program your car's chip.

You may also use a resettable key that was programmed for another vehicle. In this scenario, make sure that the key isn't damaged or that the transponder isn't altered in any way. To accomplish this, you'll need scanners or a computer with an USB port to scan the chip and determine its identity.

Reprogramming the transponder key is simple, but it requires an expertly designed software and scan tool. If you're new to the process it is recommended to seek help from an auto locksmith. Avoid buying used keys as they may already be programmed and will not work with your vehicle.

EZ Installer

For decades, car owners who required replacement of their key fob had no choice than to visit an auto dealer to have their key connected to the vehicle. This is because modern keys have to be "paired" to a specific vehicle in order to function in a way that required the use of expensive and complex equipment that only dealers had access to. The EZ Installer by Car Keys Express simplifies the process of pairing modern keys with vehicles for retailers and locksmiths.

The EZ Installer is a simple, "plug and play" OBD device that connects new keys to vehicles without the need for expensive equipment or programming tokens. It connects directly to the standard OBD port of the vehicle and uses an application that is mobile that provides easy-to-follow instructions. The EZ Installer works with most modern vehicles, including those that have proximity keys or push-button start. Check the compatibility guide at Tom's website to determine whether your vehicle is compatible.

If the device fails to program a remote or key purchased from Tom's into a vehicle that is compatible, a full refund is provided.


Unlike traditional programming equipment, which costs retailers and key professionals hundreds of thousands of dollars in "token" fees per key, the EZ Installer Pro does not charge these costs. It can be used as long as a key professional or retailer wants. The EZ Installer also eliminates the necessity for expensive monthly service contracts and updates, meaning that it will save retailers money while providing customers with the same high-quality service as OEM equipment. It also offers a leading warranty that covers both hardware and software for the duration of your life.

Tools

Locksmiths, auto mechanics, and owners of vehicles can utilize car key programming tools to create new keys for cars. These tools can communicate with the vehicle's immobilizer system to create new keys and remote controls. They can also be used to clone existing keys and create duplicate keys. These tools are an invaluable tool for anyone who owns a vehicle.

Autel Maxisys MS906BT is one of the most well-known tools for programming keys for cars. This vehicle diagnostic scanner has advanced features that are OE-grade and is compatible with most of the major brands. It also has a key programming function and can backup current important data.
