Automotive Locksmith Key Programming
The majority of modern cars require some form of key programming. Depending on the vehicle's make and model, the process could be as simple as onboard programming using a spare working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian automakers share their programming protocol with auto tool makers, so they can create hardware or software for locksmiths in the automotive industry.
Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves of low-level. The microchips are equipped with an unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has been an immense success in stopping auto theft. It has also saved many car owners a lot of money as they don't need to replace their vehicles.
The principle of the transponder system is to make it hard for thieves to open the doors of your vehicle without the correct key. In the past, thieves would force your ignition switch to the "on" position with an ordinary screwdriver or use hot wires to disable the system altogether. These types of thefts have drastically decreased with the introduction of the transponder chip.
When you place the transponder key in the ignition, the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed with the frequency of the chip in the key. The car's onboard computer will recognise that the key is valid and allow fuel to flow, power the starter or begin it.
Some vehicles only recognize specific type of transponder chip depending on the manufacturer. Therefore, it is essential that your automotive locksmith is equipped with the correct equipment to program your car's keys and remotes.
A reputable locksmith for automotive will possess a multi-vehicle programing tool that can be used on a variety of different car models and manufacturers. This is a far cheaper option than buying specific tools for each model of vehicle. They are not as common however, there are specialist automotive key programmers that can only be used on a specific brand of vehicle. The best automotive locksmiths have the tools to work on any vehicle. Make sure you select an established company that has this type of equipment.
Key FOBs
The name implies that key FOBs contain transponder chips that can be programmed to enable your car to recognize and unlock the doors or start the engine using push-button ignition. They also have buttons you can press to activate features like trunk release, door locks or fuel flap control. Some fobs have additional functions that can be controlled using the press of a button, such as the "smart" key fob that lets you summon your car into tight parking spots as you would with a Tesla or Genesis GV60.
While some replacement keys can be programmed with the assistance of a user's manual but you'll usually require an automotive locksmith to have a new one programmed if yours stops working. This is because an expert locksmith has the right equipment and access to the tools for programming needed to connect your car's computer to the on-board diagnostics (OBD) port located beneath the steering wheel.
Most key fobs today have security features that make it difficult for attackers to clone or replicate the signals they transmit. They include pseudo-random generators that generate a new unlock code each time you press the button on the key fob. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases, you can buy an alternative keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of the major US and Asian car manufacturers have key fob programming protocols with third-party firms that create the tools auto locksmiths use to program their customers' keys.
While some of the aftermarket key fobs are marketed as being compatible with any vehicle however, the majority of locksmiths for automotive don't recommend using them because they will likely only work poorly or not at all. Instead, they suggest purchasing fobs designed specifically for your vehicle, so that you can be sure they'll function correctly and are less prone to issues such as interfering or incompatibility. This will save you money in the long run by avoiding costly repairs or replacing the fobs.
Tool for Programming Vehicle Manufacturers'

Key fobs are a bit more complex than your traditional mechanical keys, which is why you'll typically find them in the hands of a reputable professional auto locksmith. The cost of a key fob may vary based on the vehicle model and the key type however, they generally cost between $85 to $400. This includes labor costs to program the keyfob as well as any replacement parts.
Car key fobs are more complicated due to the fact that they use an operating system that communicates with the onboard computer of the car. The software blocks unauthorized access by only allowing the key to function if it has been programmed for the specific car. If you change your keys, you will have to program the new key fob into the car for it to function.
This is done by using a programming tool for car keys that is compatible with your vehicle's brand. This tool allows locksmiths to connect to the OBD port of the vehicle and then enter programming mode. Key programming devices can be a handheld device that is inexpensive or one that is fancy and can do more than just program keys (like reading the eeprom file inside the ECU).
Some people attempt to program their keys on their own using these tools. However this should be left website to an expert auto locksmith. It's easy to make a mistake with the software systems if you don't know the nuances. This could result in damage.

On-Board programming

Once the key is received, your locksmith will link the programming scanner to your car's diagnostic port. This will put the car into a special programing mode, which will allow locksmiths to add keys 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 to the list of approved keys. In some cases the scanner may also be able to erase keys that have been stolen or lost from the system.
You can also program new keys with the EEPROM. It is more complicated and requires a deep understanding of how electronic systems function. It is best to delegate it to a professional with experience with these systems.
Onboard programming is the quickest method for locksmiths to program the new key. If everything is done correctly, it can take just one minute. If the key is not in the correct condition or the procedure isn't followed exactly, the process can take as long as a half hour.
There are numerous key programmer scanners that support different vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they can be used with a variety of vehicle models. No system can program every vehicle. They are also expensive. It is best to buy one that will receive regular updates from the manufacturer whenever new technologies are introduced. Your computer's programming software will soon become obsolete if you don't do this.
