Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the model and make, the process may be as simple as using an extra key to program the onboard computer or as complex as OBD2 programming or EEPROM.
Most US and Asian car makers share their programming protocols with auto tool makers to allow them to develop tools and hardware for automotive locksmiths to use.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to stop car theft. These are tiny computer microchips which emit low-level radio waves. They have 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, it will shut down the engine. This technology has proven to be extremely successful in preventing theft of cars. It has also saved many car owners a lot of money because they don't have to replace their cars.
The basic idea behind the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, thieves would simply push your car's ignition switch into the "on" position with the flat screwdriver, or make use of hot-wires to bypass the system entirely. Transponder chips have drastically reduced the number of thefts.
When you insert the transponder key in the ignition the signal is received by an antenna that is hidden within the barrel. The antenna is programmed to match the frequency of the chip in the key. The onboard computer in the car will recognize the key as being valid and allow fuel flow and start the starter. start the engine.
Some vehicles only recognize certain type of transponder chip according to the manufacturer. It is therefore important that your locksmith for cars is equipped with the appropriate equipment to program your car's keys and remotes.
A reputable locksmith for automotive will have a multi-vehicle programming device which can be used with different models and brands of cars. This is a cheaper option than buying separate tools for each type of vehicle. There are also specialised key programming tools for automobiles that can only be used on specific models of vehicles however, they are less popular. The top automotive locksmiths have the tools needed to work on any vehicle. Be sure to choose a reliable company that is equipped with this kind of equipment.
Key FOBs
The key FOBs are programmable transponder chips that allow your vehicle to unlock doors and begin the engine with the push of a button. They also have buttons you can push to activate features like trunk release, door locks or control of the fuel flap. Certain fobs come with additional functions that can be controlled using the button presses like a "smart" key fob that allows you to bring your car into tight parking spots similar to a Tesla or Genesis GV60.
While some replacement keys can be programmed by you with the assistance of a user's manual, you'll often require an auto locksmith to have a new one programmed if yours stops working. A professional is better equipped to connect the computer of your car via the OBD port located under the steering wheel.
The majority of key fobs are equipped with security features to make it more difficult for criminals to replicate and clone the signals they transmit. Some key fobs have pseudo-random code generators that generate a unique unlock code every time you press the button. This prevents attackers capturing and playing back the unlock signal to gain access to your vehicle.
In many cases you can buy a replacement key fob from the dealership or another retailer and have it programmed by a locksmith for your vehicle to work with your specific vehicle. This is because the majority of the major US and Asian automobile manufacturers use key fob programming protocols with third-party companies who produce the tools locksmiths use to programme keys for their customers.
While some aftermarket key fobs are advertised as compatible with all vehicles, most automotive locksmiths don't recommend using them since they are likely to function poorly or not at all. Instead, they suggest purchasing fobs that are specifically made for your vehicle, so that you are certain they'll function correctly and are less prone to issues such as interfering or not working. This will save you money over time, as you avoid costly repairs or replacements for your fobs.

Key fobs with embedded security features that will prevent hot-wiring (like in a film) and the car won't start if it doesn't have the correct key.
Key fobs are a little more complex than a standard mechanical key. This is why they are usually in the hands of seasoned professional auto locksmiths. The cost of a key fob may differ based on the vehicle model and the key type, but they typically run between $85 and $400. This includes the labor required to program the key fob, as well as the costs for any required replacement parts.
These car key fobs are more complex because they utilize software that interacts with the computer onboard of the car. The software blocks access to unauthorised users by only permitting keys that have been programmed specifically for a particular car to work. This means that if you get your keys replaced, you'll need to have the new key fob programed to the car in order for it to function.
This is accomplished by using a tool for programming keys for cars that are compatible with the vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter a programming mode. The key programming tool could be a simple handheld device or a high-end one that is capable of performing many things that go beyond key programming (like reading and cloning Eeprom files within the ECU).

You can also program new keys with EEPROM. It is more complex and requires a thorough understanding of electronic systems. It's best to leave it to a professional who has experience with these systems.
Locksmiths can program a key quickly with onboard programming. It can take as little as a minute when everything is done correctly. If the key is not in the right condition or the procedure isn't followed exactly, the process can take up to half an hour.
