What Are Key Programmers? The majority of modern vehicles have ignition and key systems that require reprogramming at some point. This is the reason key programmers come in handy. There are three scenarios where shops may require key programming capabilities. They could run into a no-start diagnostic or a customer is in need of an extra key or the keys are missing. OBD-II Key Programmer Units A car key programmer is a device that allows one to modify or add a code of a transponder in an automobile's keyfob. This can be done to permit a different key to operate the car, or to permit someone else to drive the vehicle. These devices are expensive and may require training and expertise to operate. These devices are usually used by auto repair shops or locksmiths with professional experience however, they are difficult to locate for home mechanics. The best programmers are designed to be simple to use however, others are more complex and designed for professional use. They can be difficult to operate without instruction.

The ideal device for you will depend on your requirements and a few even come with the option of a remote control that permits you to use the device while in the driver's seat.

Self-Programming Keys Locksmiths are often able to re-program key fobs and new car keys. However, this procedure requires the use of an instrument known as a “key programmer.” These devices could be standalone units or part of a more sophisticated scan tools designed by automotive mechanics, manufacturers and dealers. The main programmers are designed to work bidirectionally with your vehicle's OBD II connector. They can be used with a variety of models and makes. Certain car makers will not allow a locksmith to reprogram keys for their automobiles. This is to ensure security. This stops anyone from creating a copy of your existing working key and then using it to steal your car. In many cases, the car's computer won't let the key to be programmed more then once. This is the way the system stops hot-wiring stolen vehicles like in films. Even the T-800 Terminator could not be able to leave with Sarah Conner's car! Certain car manufacturers do this because they don't want to include instructions on how to make additional keys or reprogram a key fob in their owner's manuals. These companies assume that their customers will be idiots and won't be able to figure out how to do things on their own. They make it more difficult for them to do so. Fortunately that the majority of major US and Asian automakers have shared their key programming protocols with tool makers who design and manufacture this type of device. Consequently, there are a wide variety of key programmers available for these brands of cars that permit reprogramming existing keys or the creation of additional fobs. The devices are priced differently in terms of cost and performance, but they are generally inexpensive enough to be used by a locksmith to provide this kind of service. The simplest, least expensive devices are designed to work with one or two vehicles, whereas the more sophisticated, sophisticated ones are sold to dealers and can cost a lot of money. You should go through online reviews and do some research before you buy an important programmer. Transponder Clone Keys Whenever a car key is inserted into the ignition, it transmits an low-level radio signal to the transponder chip. The signal is accompanied by an individual serial number that ensures that the key is the correct one for the vehicle. The system is designed to make it difficult to steal a vehicle because the vehicle will only start once it receives the right signal from the correct key. Key cloning devices can be used to duplicate keys, without having to reprogram the computer in the car to recognize the new key. Cloning a car key requires two things: a method to get the data off of the original key and a device that can write that data onto another chip. The majority of cloning devices are compatible well with a variety of keys. Some machines, however, only work with certain types and brands. A good cloning system will not only determine if there is a chip within the key but also the type of chip it is. This is crucial because there are many different types and brands of chips that are used in the present. It is easy to mix up the chips when switching them between different key shells, so it is crucial that a cloning device differentiate between them. Advanced systems will have an identification feature that lets them identify the different types of chips. This will prevent keys from being programmed for an incompatible vehicle, and it's also a defense against stealing the original key in order to use it in a different vehicle. The right equipment will allow you to replace keys on-site, thereby saving your customers the hassle and cost of having to return their vehicle to the dealer. The equipment also enables locksmiths to provide more services and attract customers. In just a few short years the cost of the mere a few dozen keys per week will be enough to pay for the majority of these units. This is a good time to begin offering this service, since many of the top automakers are urging their dealers to offer more key duplication and replacement services. Key Fobs Key fobs are useful for a variety of reasons. They are popular in apartment building access systems and can also be used to control small household devices, like garage door openers. They use radio frequency identification or RFID. When you tap the fob against the reader, it transmits a specific frequency that can be identified and allowed access. These systems are usually monitored and controlled from a central computer system which means you can grant different levels of access to different people. You can also utilize the key fob to lock or unlock your vehicle. It is more secure than a physical key as it blocks the possibility that someone could copy the key. Plus, you can easily remove your key fob from use if it is stolen or lost unlike traditional keys. A key fob can be used to gain access to a facility without the requirement of an account number or password. This is an extremely useful feature for industrial and commercial environments where it is difficult to track and manage access to employees. Fobs are also useful in preventing cyber attacks, that can be caused by lost or stolen keys that provide malicious users with access to a system to install malware or steal data, and also engage in other cybercrimes. Fobs can be used in apartment complexes or gated communities to permit residents access to common areas like the pool and storage facilities. They can also be programmed to open doors at individual homes, which makes it easy for a tenant to allow access to cleaning crews, babysitters and pet walkers. To program a keyfob you'll need a device capable of communicating with computer system in the vehicle. Many locksmiths and auto technicians utilize an instrument known as the Smart Pro, which is a powerful programming device that can handle all major brands and models. It also has the ability to read transponder chip data, clone key and perform some OE-level programming. Although it's not inexpensive, it's a great option for anyone in need of an effective key programming tool.
