Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Based on the model and make, the process may be as simple as using a spare key to program the onboard computer, or as complicated as OBD2 programming or EEPROM.
The majority of US and Asian car makers share their programming protocols with auto tool makers so that they can develop hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
Transponder chips are found in a lot of modern cars to prevent car theft. These are tiny computer microchips that emit low-level radio waves. The microchips are equipped with an unique serial number that authenticates your keys when you insert it into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has been extremely successful in preventing car theft. This technology has also saved car owners a great deal of money since they don't have to buy new vehicles.
The basic concept behind the transponder system is to make it impossible for thieves to get into your car without the right key. In the past, car thieves would use an ordinary screwdriver to force the ignition switch in your car into "on" mode, or hot-wire it in order to bypass the system. Transponder chips have dramatically reduced these types of thefts.
When you insert the transponder keys in the ignition, the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed with the frequency of the chip within the key. The car's onboard computer will then recognise that the key is valid and allow fuel to flow, power the starter or start it.
Some vehicles only recognize a specific type of transponder chip, depending on the manufacturer. This is why it is important to ensure that your automotive locksmith has the right equipment to program your vehicle's keys and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming device that is compatible with different models and car brands. This is a more cost-effective option than purchasing individual tools for every brand of vehicle. These are less common however, there are specialist automotive key programming tools that can only be used on a specific model of vehicle. The best automotive locksmiths are equipped to work on any vehicle. Be sure to choose an established company that has this kind of equipment.
Key FOBs
Key FOBs are programmeable transponder chip devices that allow your vehicle to open doors and start the engine using the push of a button ignition. It is also possible to press buttons to activate features such as trunk locks, door locks or controls for the fuel flap. Some fobs also have additional functions that can be controlled with the press of a button, such as the "smart" key fob that lets you summon your car into parking spaces that are difficult to access, like you would with a Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the assistance of a user guide, but you'll need to contact an automotive locksmith in the event that yours isn't working. A professional is better equipped to connect your computer to the vehicle via the OBD port on the steering wheel.
Most key fobs today have security features that make it difficult for hackers to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators that generate a unique unlock code each time you press the button. This stops attackers from recording and playing back the unlock signal in order to gain access to your vehicle.
In some cases, you can buy the replacement keyfob at an auto dealer or other retailer. Your locksmith at your auto will then program it to work with your vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party firms who produce the tools used by auto locksmiths to program their customer's keys.
Certain aftermarket key fobs can be advertised as compatible with any vehicle. However, locksmiths for automotive strongly discourage using them as they are likely to work poorly or not at all. They recommend buying fobs made specifically for your vehicle to ensure they will work properly and are less prone to issues like interference or incompatibility. This will save you money over time, as you avoid costly repairs or replacements of your fobs.

One key element of this technology is a transponder chip that requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to work. Key fobs come with built-in security features that will prevent hot-wiring (like in a film) and the car won't start without the correct key.
Key fobs are slightly more complicated than a traditional mechanical key. This is why they are usually handled by experienced professional auto locksmiths. The cost of a key fob will vary based on the vehicle model and the type of key, but they typically run between $85 to $400. This includes labor costs to program the keyfob as well as any replacement parts.
To make the process more difficult the car key fobs use a special software system to work with the car's onboard computer. The software blocks access to unauthorized users by allowing the key to operate if it has been programmed to that specific car. If you change your keys, you will have to program the new key fob to the car in order for it to function.
This is done by using a programming tool for keys for cars that are compatible with the brand of your vehicle. This tool permits a locksmith to connect to the OBD port in the vehicle, and then enter the programming mode. The key programming tool could be a handheld device that is inexpensive device or a fancy one that can perform a wide range of things that go beyond key programming (like reading and cloning the eeprom files in the ECU).
Some people attempt to program their keys by themselves using these tools. However, this is best left to an expert auto locksmith.

EEPROM programming is another method that can be used to program new car keys. It is more complicated and requires a thorough understanding of how electronic systems operate. This is why it's best left to a professional who has a lot of experience working on these types of systems.
Locksmiths can program a key quickly by using onboard programming. It takes as little as a minute when everything is done correctly. However, if the key isn't in correct situation or the procedure is not adhered to, it could take as long as a half hour.
There are numerous key programmer scanners available that support different car models and makes. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their wide range of vehicle models. However, neither can program every vehicle on the market.
