Automotive Locksmith Key Programming Modern cars require some type of key programming. Based on the model and manufacturer the process could be as simple as using a spare key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming. The majority of US and Asian car manufacturers share their programming protocols with auto tool makers in order to create software and hardware for automotive locksmiths to use. Transponder Chips Transponder chips are used in many newer cars to prevent car theft. These are tiny computer microchips which emit low-level radio waves. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been extremely successful in preventing car theft.

Transponder chips have drastically reduced these types of thefts. When you place the transponder key into the ignition, the signal is picked up by an antenna hidden around the barrel. The antenna is programmed with the frequency of the chip within the key. The car's computer onboard will recognize that the key is valid and allow fuel to flow, turn the starter or begin it. Depending on the manufacturer, certain vehicles can only recognize certain types of transponder chip. This is why it is essential to ensure that your locksmith for automotive has the appropriate equipment to program your car's key and fobs correctly.

Certain fobs come with additional functions that can be controlled with the press of a button for example, a “smart” key fob that lets you summon your car into tight parking spots as you would with a Tesla or Genesis GV60.

Toolkits for Programming Vehicles of Manufacturers The automotive industry has come a long way, and today's vehicles require computer technology to function. A transponder chip is an essential component of this technology. It needs to be programmed by a locksmith mechanic, or dealer to work. Key fobs come with built-in security features that prevent hot-wiring (like in a film) and the car won't start if it doesn't have the right key. These key fobs are a little more complex than the mechanical keys and that's why they are usually in the hands of a reputable professional auto locksmith. The cost of a car key fob varies depending on the type and model of key, but it is generally between $85 to $400. This includes labor costs to program the keyfob as well as any replacement parts. To complicate the process, these car key fobs utilize a specific software system to work with the car's onboard computer. The software prevents unauthorized access by allowing the key to operate if it has been programmed to that specific car. If you change your keys, you will need to program the new key fob in the car to allow it to work. This is accomplished using a programming tool for car keys that is compatible with the brand of your vehicle. This tool lets the locksmith connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. Key programming devices can be a handheld device that is inexpensive or one that is extravagant and can do more than just programming keys (like reading the eeprom file in the ECU). Some people might attempt to program their keys themselves using these tools. However, this is best left to an expert auto locksmith. It is easy to make mistakes using the software systems if you don't understand the nuances. This could lead to damage. It's important to keep in mind that an experienced professional will help you avoid these problems. On-Board Programming If your vehicle is old enough that you'll have a traditional key made of metal to open the doors and turn on the ignition. However, modern cars come with transponder chips that need to be recognized by the car's computer system to allow it to start. This adds another layer of security to keep thieves from stealing the car and driving away with a stolen vehicle. A certified locksmith will have the right tools and software to create a new key that is compatible with the security system of your vehicle. Your locksmith will have to purchase an uncut key that is that is compatible with the vehicle's model and make. Once your locksmith has the key, he'll connect the programming scanner to the diagnostic port of your vehicle. This will put your car into an exclusive programming mode that will allow the locksmith to add a new key to the system. The key programmer scanner communicates with the computer of the vehicle to send the code. The computer will recognize the code and add it into the list of approved key. In some instances the scanner may also be able to delete lost or stolen keys from the system. Programming EEPROM is another method that can be used to program new car keys. It is more complex and requires an in-depth understanding of how electronic systems operate. This is why it's best left to a professional who has years of expertise working on these types of systems. Locksmiths can program keys quickly by using onboard programming. It can take as little as an hour if everything is executed correctly. If the key is not in good working order or the procedure isn't followed precisely, the procedure could be as long as half an hour. There are numerous key programmer scanners which can work with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they cover a wide range of vehicle models. However, no system can be programmed for every vehicle on the market. These devices are also expensive. It's a good idea buy a programmer that receives regular updates as the manufacturer develops new technologies. In the event that your machine is not updated, it will be obsolete in a short time.
