Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the car's make and model, the procedure can be as simple as programming onboard using an extra working key or as complex as EEPROM or OBD2 programming.
The majority of US and Asian car makers have programming protocols that they share with auto tool manufacturers to allow them to develop software and hardware for locksmiths in the automotive industry to use.
Transponder Chips
Most modern cars are equipped with transponder chips in order to prevent theft. These are tiny computer microchips which emit radio waves at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has proven to be an immense success in stopping auto theft. This technology has also helped car owners save a good deal of money as they do not have to purchase new cars.
The principle of the transponder system is to make it impossible for thieves to start your vehicle without a valid key. In the past, thieves would use the flat screwdriver to push the ignition switch in your car to go into "on" mode, or wire it hot to get around the system. Transponder chips have drastically decreased the likelihood of theft.
When you insert the transponder key into the ignition, the signal is received by an antenna that is concealed around the barrel. The antenna is programmed to match the frequency of the chip within the key. The computer onboard of the car will then recognise the key as being valid and allow fuel flow, power the starter or start the engine.
Depending on the manufacturer, certain vehicles can only recognize a specific type of transponder chip. It is therefore essential that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes.
A reputable locksmith for automotive will have a multi-vehicle programming device that can be used on many different car models and manufacturers. This is a less expensive alternative to purchasing specific tools for each type of vehicle. There are also specially-designed automotive key programmer devices that are only suitable for specific models of vehicles however, they are less popular. The top automotive locksmiths are equipped to work on any vehicle. Make sure you select a reliable company that is equipped with this kind of equipment.
Key FOBs
Key FOBs are programmeable transponder chip devices that permit your vehicle to open doors and start the engine with the push of a button ignition. You can also press buttons to activate features like trunk locks, door locks or fuel flap controls. Certain fobs can be controlled by pressing buttons. For example, a "smart key" that allows you summon your car to parking spaces, such as a Tesla or Genesis GV60.
While some replacement keys can be programmed by you with the help of a user manual but you'll usually require an automotive locksmith to get a new one programmed in case yours stops working. A professional is better equipped to connect your computer to the vehicle via the OBD port located under the steering wheel.
Most key fobs today include security features that make it difficult for attackers to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators, which generate a different unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal in order to gain access to your car.
In many cases you can buy an additional key fob at the dealership or another retailer and have it programmable by your automotive locksmith to work with your particular vehicle. This is because the majority of major US and Asian auto manufacturers share their key-fob programming protocols with the third-party firms who create the tools used by auto locksmiths to program their customer's keys.
Although some key fobs from the aftermarket are marketed as being compatible with all vehicles however, the majority of locksmiths for automotive do not recommend using them as they're likely to work poorly or not at all. Instead, they suggest buying 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 incompatibility. This will save you money over time, as you avoid costly repairs or replacements for your fobs.
Toolkits for Programming Vehicles of Manufacturers

One of the key components of this technology is a transponder chip which requires to be programmed to the vehicle by a locksmith or dealer/mechanic in order to function. Key fobs are fitted with security features to stop hot-wiring, like in a movie. The car will not start without the correct keys.
Key fobs are more complicated than a traditional mechanical keys and are the reason they are usually in the hands of a skilled professional auto locksmith. The cost of a car key fob varies depending on the model and type of key, but it is generally between $85 and $400. This includes the cost of labor to program the key fob and the costs for any required replacement parts.
To complicate the process the car key fobs use a special software system to communicate with the car's onboard computer. The software blocks unauthorized access by only allowing the key to function if it has been programmed to that specific car. If you change your keys, you will need to program the new key fob to the car for it to work.
The most popular method to accomplish this is using an auto key programming tool that is compatible with the model of the vehicle. This tool allows a locksmith to connect to the OBD port on the vehicle and then enter programming mode. Key programming tools can be a simple handheld device or a high-end one that can perform various things that go beyond key programming (like reading and cloning the Eeprom files within the ECU).
Some people might attempt to program their keys themselves using these tools. However this should be left to an expert auto locksmith. It's easy to make a mistake when using software systems if you don't know the intricacies. This can lead to damage.

On-Board Programming
If your car is of a certain age to be considered old-fashioned, you'll have a traditional metal key that you can use to open the doors and turn off the ignition.

This will put the vehicle into the mode of programming that allows the locksmith to add a new key into the system.
To accomplish this, the key programmer scanner will communicate with the car's computer and send an exact code. The computer will be able to recognize the code and add it to the list of keys approved by. In some cases the scanner may also be able to remove keys that here are stolen or lost from the system.
Programming EEPROM is another method that can be used to program new car keys. It is more complicated and requires a thorough understanding of electronic systems. It is best to leave it to a professional who has knowledge of these systems.
Locksmiths can program a key quickly using onboard programming. If everything is done correctly it could take as little as one minute. However, if the key isn't in proper state or the procedure isn't strictly followed, it could take as long as a half hour.
There are numerous key programmer scanners that support different vehicle models and makes. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they support a broad range of automobile models. However, no system will be able to program every single vehicle that exists. These devices are also expensive. It's a good idea purchase a computer that receives regular updates as the manufacturer releases new technologies. Your programming machine will quickly become outdated if you don't do this.
