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 onboard programming with a spare working key or as complex as OBD2 or EEPROM programming.
Most US and Asian automobile manufacturers use the same programming protocols as auto tool manufacturers to allow them to develop hardware and software for locksmiths in the automotive industry to use.
Transponder Chips
The majority of newer cars have what are called transponder chips to prevent car theft. These are small computer microchips that emit radio signals at a low level. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is plugged into the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down. This technology has proven to be an immense success in stopping auto theft. This technology has also helped car owners save a huge deal of money by not having to replace their vehicles.
The basic concept behind the transponder system is to make it difficult for thieves to get into your vehicle without a valid key. In car key programmer , car thieves would simply force the ignition switch of your car into the "on" position with an ordinary screwdriver or make use of hot-wires to bypass the system altogether. Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will send an electrical signal that is detected by a hidden antenna that is positioned around the barrel of the ignition. The antenna is programmed with the frequency of the chip inside the key. The car's onboard computer will then recognise that the key is genuine and allow fuel to flow, power up the starter, or even begin it.
Some vehicles only recognize specific type of transponder chip according to the manufacturer. This is why it is crucial to make sure that your automotive locksmith has the appropriate equipment to program your vehicle's keys and fobs correctly.
A reputable locksmith for cars should have a multi-vehicle key programming device that can work on many different car manufacturers and models.

These aren't as popular, but there are specialised automotive key programmers that can only work on a particular brand of vehicle. The top automotive locksmiths have the appropriate tools to work on any type of vehicle, so ensure you choose a reputable business that offers these types of tools.
Key FOBs
As the name implies, key FOBs are home to the transponder chips that can be programmed to allow your car to recognize and unlock the doors or start the engine using push-button ignition. They also have buttons you can push to activate features like door locks, trunk release or control of the fuel flap. Some fobs have additional functions that can be controlled using the press of a button for example, the "smart" key fob that allows you to get your car to parking spots that are tight similar to a Tesla or Genesis GV60.
You can program some replacement key fobs yourself using the assistance of a user guide, but you'll need to call an automotive locksmith if the one you have isn't working. A professional locksmith 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. Certain key fobs come with pseudo-random code generators that generate a new unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In some cases you can purchase the replacement keyfob at an auto dealer or other retailer. Your locksmith at your auto will then program it to work with your car. This is because the majority of the major US and Asian car makers use key fob programming protocols with third-party firms that make the tools that locksmiths for auto utilize to programme keys for their customers.

This will save money in the long run by avoiding costly repairs or replacements of your fobs.
Tool for programming the vehicle manufacturers

The cost of the car key fob is according to the type and model of key, but is generally between $85 and $400. This includes labor costs to program the keyfob as well as any replacement parts.
To make the process more complicated the car key fobs make use of a special software to communicate with the car's onboard computer. The software prevents unauthorized access by only permitting the key to function if it has been programmed to that specific car. This means that if you get your keys replaced, you'll need to have the new key fob programed to the car to function.
This is accomplished using a programming tool for keys for cars that are compatible with the vehicle's brand. This tool allows locksmiths to connect to the OBD port of the vehicle and then enter programming mode. Key programming tools can either be an inexpensive handheld device or a more expensive one that can perform a wide range of things beyond just key programming (like reading and cloning the eeprom files in the ECU).
Some people may try to program their keys by themselves using these tools. However this should be left to an experienced auto locksmith. It's easy to make a mistake when using software systems if you don't understand the nuances. This could lead to damage.

You can also program new keys by using EEPROM. It is more complicated and requires a thorough understanding of how electronic systems operate. It is best to delegate it to a professional who has experience with these systems.
Onboard programming is the most efficient way for a locksmith to program the new key. It takes as little as an hour if everything is executed correctly. However, if the key isn't placed in the right state or the procedure isn't adhered to, it could take up to a half hour.
There are numerous key programmer scanners that can be used with different car models and makes. Both the Smart Pro and Autel IM608 Pro have become extremely popular among locksmiths due to their wide range of models for vehicles. No system can program every vehicle.
