Automotive Locksmith Key Programming
Modern cars need some type of key programming. Based on the model and make the process could be as simple as using a spare key to program the onboard computer or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian auto manufacturers use the same programming protocols as auto tool makers, which means they can design tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are found in a lot of modern cars to guard against theft of vehicles. These are microchips in the form of computers that emit radio signals at a low level. They have a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has proven to be an immense success in stopping auto theft. This technology has also helped car owners save a good amount of money by not having to buy new vehicles.
The transponder system's basic idea is to make it hard for thieves to start your vehicle without a valid key. In the past, car thieves would force the ignition switch of your car into the "on" position with a flat screwdriver or even hot-wire the car to bypass the system completely. These types of thefts have been drastically reduced with the introduction of the transponder chip.
When you insert the transponder key in the ignition, the signal is received by an antenna hidden around the barrel. This antenna is programmed so that it can detect the particular frequency of the chip within the key. The onboard computer of the car will then recognise the key as valid and allow fuel flow and power the starter to begin the engine.
Based on the manufacturer, certain vehicles can only recognize a specific type of transponder chip. It is therefore essential that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that is compatible with different models and manufacturers of cars. This is a cheaper alternative to purchasing individual tools for every brand of vehicle. They are not as common however, there are specialist automotive key programming tools that can only work on a particular type of vehicle. The best automotive locksmiths have the tools to work on any vehicle. Make sure you select a reputable firm that has this type of equipment.
Key FOBs
As the name implies, key FOBs house the transponder chips programmable that enable your car to recognize and unlock the doors or start the engine using push-button ignition. They also have buttons that you can press to trigger features like door locks, trunk release or control of the fuel flap. Some fobs have additional functions that can be controlled by the button presses for example, a "smart" key fob that lets you summon your car into tight parking spots similar to a Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help from an instruction manual, however you'll need to contact an automotive locksmith if yours isn't working. This is because a professional locksmith has the specialized equipment and access to the programming tools needed to connect your car's computer to the on-board diagnostics (OBD) port located beneath the steering wheel.
The majority of key fobs are equipped with security features to make it more difficult for criminals to duplicate and copy the signals they transmit. They include pseudo-random generators that generate a fresh unlock code each time you press the button on your key fob. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In most instances you can purchase an alternative key fob from the dealer or other retailer and then have it programmed by your automotive locksmith to be compatible with your specific vehicle. This is because most of the major US and Asian car manufacturers share their key fob programming protocols with third-party companies who make the tools that locksmiths for auto employ to program their customers' keys.
Certain key fobs from the aftermarket may be marketed as compatible with any vehicle. However, programming car key for automotive strongly discourage using them as they're likely to function 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 function correctly and are less susceptible to issues such as interfering or incompatibility. This will save you money in the long run by avoiding expensive repairs or replacing your fobs.
Vehicle Manufacturers' Programming Tools
The automotive industry has come a long way and today's vehicles need computer technology to function. Transponder chips are an essential part of this technology. It has to be programmed by a locksmith, mechanic, or dealer to work. These key fobs are equipped with security features to stop hot-wiring, as in a movie. The car will not start if the keys are not correct.
Key fobs are a little more complex than a conventional mechanical key. This is why they are usually handled by experienced professional auto locksmiths. The cost of a car key fob varies dependent on the type and model of key, but it is typically between $85 and $400. This includes the labor to program the key fob as well as the costs for any necessary replacement parts.
To make the process more complicated, these car key fobs use a special software system to work with the car's onboard computer. The software blocks unauthorized access by allowing the key to function if it has been programmed to the car in question. If you replace your keys, you'll have to program the new key fob in the car to allow it to work.
This is accomplished using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. The key programming device can be an handheld device that is cheap or sophisticated and capable of doing more than just programming keys (like reading the eeprom file inside the ECU).
While some may try to program their own keys with these tools, it's a job best left to a professional auto locksmith. It's easy to make mistakes using the software systems if you aren't aware of the intricacies. This could lead to damage. It's important to remember that a professional with experience will help you avoid these issues.
On-Board programming
If your car is old enough it could still be equipped with a metal key that you can use to open doors and turn the ignition. However, modern vehicles are equipped with transponder chips that must be recognized by the computer system of the car to allow it to start. This is an additional layer of security to keep thieves from stealing the car and then driving off with a stolen vehicle. A certified locksmith will have the necessary tools and software to create a new key that works with the security system of your vehicle.
Your locksmith will need to obtain a key blank that is that is compatible with the vehicle's model and make. Once the key is in your possession, your locksmith will link the programming scanner to your car's diagnostic port. This will put the vehicle into an exclusive programming mode which will allow the locksmith to add a new key into the system.

The key programmer scanner communicates with the computer of the vehicle to transmit the code. The computer will detect the code and add it to the list of approved key. In some cases the scanner may also be able to delete keys that have been stolen or lost from the system.
The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires a thorough understanding of how electronic systems function. This is why it's best left to a professional who has years of expertise working on these types of systems.
Locksmiths can program keys quickly using onboard programming. If everything is done correctly it could take as little as one minute. If the key isn't in proper situation or the procedure isn't adhered to, it could take up to an hour.
There are many different key programmer scanners that can be used with different models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both very popular amongst locksmiths because they support a broad range of vehicle models. The system cannot program every vehicle. Additionally, these devices cost a lot. It is best to buy a programmer which will receive regular updates from the manufacturer as new technologies are developed. In the event that your machine is not updated, it will become obsolete quickly.
