Reprogramming Car Keys

Transponder keys are said to be more secure for cars and are more difficult to copy by thieves. However, a key may need to be reprogrammed when it becomes damaged or lost.

You can reprogram your key fobs at home, however you must be aware of the correct procedure. For the best results, you must have the following items:

Keys

Nearly all modern vehicles require a transponder key or fob in order to operate, providing security and anti-theft protection. The keys have to be programmed to the specific vehicle and its features by a licensed locksmith or dealer. It is expensive to replace them if they're lost, so it's best to keep extras on hand. You can purchase key fobs that can be replaced in online stores as well as numerous brick-and-mortar auto shops. How do you ensure that the one you have bought is genuine? Do you know whether it was programmed for another car or if it could be reprogrammed for yours?

If you want to program a new key the first step is to ensure that your vehicle is running. Insert the key that you wish to reprogramme into the ignition, but do not turn it. You will only have just a few seconds before the car's system resets the commands and then exits programming mode. It is important that you move quickly and don't wait between each step. Turn off the engine to avoid this. Switch the key from "on" to "off" to test the system. You should hear a chime indicating that the process was successful. The door locks will be able to cycle.

Certain cars with more modern technology have rolling key technology that stops thieves from using a stolen vehicle's key to start it. This technology is still vulnerable to a technique dubbed a replay attack, which allows thieves to record the signal from the key fob on the vehicle and reproduce it later to open the car. To prevent this, manufacturers have added an additional security feature known as the CAN bus protocol to stop attacks on hacking.

Certain manufacturers also employ special encryption on their key fobs, which are not decoded by an ordinary program. These types of cars will need to be programmed by a professional, and you should only attempt this process if you have experience working with electronic devices. Refer to the manual for your car or go to the website of the manufacturer to find out how to program it. The steps to follow will differ according to the type of vehicle.

Transponder chips

Car keys with transponder chips need special reprogramming to work. Any hardware store can offer you a new car key, but the real challenge is in making it work with your car. A reprogrammed key will need to be matched with the exact identification number of your vehicle otherwise it won't even start the engine.

Transponder chips are a common feature in modern cars and are designed to prevent car theft. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is inserted. The car then recognizes the signal and begins the engine if it matches the original frequency that was programmed into the vehicle. The car is also programmed to shut down when it detects an incompatible frequency. This makes it more difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then start it.

The chip and the key are connected via the circuit board which includes an induction coil. When the key is put in the ignition, a magnetic field is generated around the transponder. This generates a signal, which is taken up by the coil and then transmitted to the key identification number. The key's identification number is returned to the car key reprogrammed and the engine is started when the identification number matches.

There are many methods to program a transponder key however, they all require an instrument that is specifically designed for the purpose. You can purchase these tools online or at most locksmiths for cars. They are not cheap, but they are crucial for programming the chip into your car.

You can also use a reprogrammable transponder key that has been previously programmed for a different vehicle. In this instance you'll need sure that the key has not been damaged or the transponder been altered in any way. To check this, you'll need scanners or computers with a USB port to scan the chip and determine its identity.

The process of reprogramming the transponder key is simple, however it requires special software and a scanning tool. If you're just beginning, it's best to seek the assistance of an auto locksmith. You should also avoid buying second-hand keys, since they are likely already programmed and won't work with your vehicle.

EZ Installer

Until recently the time when car owners wanted to replace their key fob had to go to an authorized dealer to get it electronically paired with the vehicle. This is because modern keys need to be "paired" to a specific vehicle to function, which required expensive and complicated equipment that only dealers had access to. The EZ Installer from Car Keys Express solves this issue for retailers and locksmiths by easing the process of pairing modern keys with vehicles.

The EZ Installer is a basic, "plug and play" OBD device that pairs 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 on mobile key programming devices to provide simple instructions. The EZ Installer works with most modern vehicles that include proximity keys or push-button start. Go to the compatibility guide on Tom's website to determine if your vehicle is compatible.

A full-money-back guarantee is provided in the event that the device cannot successfully program a key or remote purchased from Tom's for a vehicle compatible.

Contrary to conventional programming equipment that costs retailers and key professionals thousands of dollars with typical per-key "token" fees, the EZ Installer Pro doesn't charge these fees at all which means it can be used as long as a retailer or key professional would like it to be. The EZ Installer also eliminates the requirement for expensive monthly service contracts and updates, so it could reduce costs for retailers while offering customers the same high-quality service as OEM equipment. It also offers a top warranty that covers both hardware and software for the duration of your life.
