Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the process can be as easy as programming onboard using a spare working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian automakers use the same programming protocols as auto tool makers, which means they can develop hardware or software for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are in many newer cars to guard against theft of vehicles. These are tiny computer microchips that emit low-level radio signals. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has proven to be an immense success in stopping auto theft. It also saves many car owners a lot of money as they don't have to buy new their cars.
The basic concept behind the transponder system is to make it hard for thieves to open the doors of your car without the right key. In the past, car thieves would force your ignition switch to the "on" position with the flat screwdriver, or make use of hot-wires to bypass the system altogether. These kinds of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits a signal that is received by a hidden antenna circling the barrel of the ignition. The antenna is programmed to detect the particular frequency of the chip inside the key. The car's onboard computer will then recognize that the key is legitimate and allow the fuel to flow, then power the starter or begin it.
Based on the manufacturer, some vehicles will only recognise the specific type of transponder chip. Therefore, it is essential that your locksmith in the automotive industry is equipped with the correct equipment to program your keys and remotes for your vehicle.
A good automotive locksmith will have a multi-vehicle programming device that can be used on many different automobile models and manufacturers. This is a cheaper option than buying specific tools for each model of vehicle. There are also specialised automotive key programmer devices that are only suitable for specific brands of vehicles however they are not as frequently used. The most reliable automotive locksmiths will have the right equipment to tackle any type of vehicle, so ensure you choose a reputable business that has these types of tools.
Key FOBs
Key FOBs are programmeable transponder chip devices that permit your vehicle to open doors and begin the engine with a push button ignition. You can also press buttons to activate features such as trunk releases, door locks or controls for the fuel flap. Some fobs can be controlled with the press of buttons. For instance the "smart key" that lets you call your car to tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the help of the user guide, however you'll need to contact an automotive locksmith if the one you have has stopped functioning. A professional locksmith is better equipped to connect the computer of your car via the OBD port on the steering wheel.
Most key fobs today have security features that make it difficult for criminals to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators, which generate a new unlock code every time you press the button. This is to prevent attackers from capturing and replaying the unlock signal in order to gain access to your vehicle.
In many instances you can buy an additional key fob at the dealer or other retailer and have it programmed by a locksmith for your vehicle to work with your particular vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with third-party companies that produce the tools used by auto locksmiths to program their customer's keys.
While some aftermarket key fobs are advertised as compatible with all vehicles, most automotive locksmiths don't recommend using them because they're likely to work poorly or not at all. Instead, they recommend purchasing fobs that are specifically made for your specific vehicle so that you are certain they'll work properly and are less susceptible to issues such as interfering or incompatibility. This will save you money over time, as you avoid costly repairs or replacements for your fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has made huge advances in the last couple of decades. Today's vehicles are computer-driven. 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 with embedded security features that prevent hot-wiring (like in a movie) and the car won't start without the right key.
Key fobs can be somewhat more complicated than a traditional mechanical key. This is why they're usually in the hands of seasoned professional auto locksmiths. The cost of a car key fob varies according to the type and model of key, but it is generally between $85 to $400. This includes the cost of labor to program the key fob as well as the cost of any needed replacement parts.
To complicate the process to make the process more complicated, these key fobs for cars use a special software system to communicate with the car's onboard computer. The software blocks access by unauthorised persons by only permitting keys that have been programmed for a specific car to work. If you change your keys, you'll have to program the new key fob into the car in order for it to work.
This is accomplished using a programming tool for car keys that is compatible with the vehicle's brand. This tool lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter a programming mode. The key programming device can be a handheld device that's cheap or extravagant and can do more than just program keys (like reading the eeprom files in the ECU).
Some people might try to program their keys by themselves using these tools. However, this is best left to an expert auto locksmith. If you're not familiar with the ins and outs of the various software systems, it's easy to accidentally change settings that could potentially damage the vehicle. It's important to remember that a professional with experience will assist you in avoiding these issues.
On-Board programming
If your vehicle is older than you, you'll still have a traditional key made of metal to use to unlock the doors and turn over the ignition.

This is a further layer of security that prevents car thieves from starting and then driving off with a stolen car. A locksmith certified will have the tools and software required to program a key that will function in your car's system.
Your locksmith will first need to obtain a blank key compatible with your vehicle's make and model. Once the key is in hand, your locksmith will link the scanner for programming to your car's diagnostic port. This will put your car into the mode of programming which will allow the locksmith to add a new key to the system.
To do this, the key programming scanner will communicate with the car's computer system to transmit an exact code. The computer will recognize the code and add it to the list of keys that are approved. In G28 some instances, a scanner can also remove keys that have been stolen or lost.
You can also program new keys using EEPROM. It is more complex and requires a deep understanding of how electronic systems work. This is why it's best left to a professional that has years of experience working on these types of systems.
Locksmiths can program keys quickly by using onboard programming. It can take less than one minute if everything is done correctly. If the key isn't in the right condition or the procedure isn't being followed exactly, the process can take up to half an hour.
There are a variety of key programmer scanners that support various models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both very popular with locksmiths since they can be used with a variety of vehicle models. However, neither 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 when the manufacturer introduces new technologies. Your programming machine will quickly become outdated if you don't take this step.
