The Most Pervasive Issues In Automotive Locksmith Key Programming
Automotive Locksmith Key ProgrammingModern cars require some type of key programming. Depending on the car's maker and model, the procedure could be as simple as onboard programming with an extra working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian auto manufacturers share their programming protocol with auto tool makers, so they can create software or hardware for locksmiths in the automotive industry.
Transponder Chips
Transponder chips are found in many newer cars to prevent car theft. These are microchips in the form of computers that emit low-level radio signals. They have a unique serial number that authenticates your keys when you plug it 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 enormous success in preventing theft of cars. This technology has also saved car owners a great deal of money since they don't have to replace their vehicles.
The basic idea behind the transponder system is to make it difficult for thieves to get into your car without the proper key. In the past car thieves used a flat screwdriver to force the ignition switch in your car into "on" mode or even hot-wire it to get around the system. These types of thefts have been drastically reduced thanks to the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it transmits an electrical signal that is picked up by a hidden antenna circling the barrel of the ignition. This antenna is programmed to detect the particular frequency of the chip inside the key. The car's computer onboard will detect that the key is genuine and allow fuel to flow, power up the starter or begin it.
Based on the manufacturer, certain vehicles can only accept a specific type of transponder chip. This is why it is crucial to make sure that your locksmith in the automotive industry has the right equipment to program your car's keys and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming device that can work on many different models and manufacturers of cars. This is a cheaper alternative to purchasing separate tools for each brand of vehicle. These aren't as popular, but there are specialised automotive key programming tools that can only work on a particular brand of vehicle. The most reliable automotive locksmiths will have the appropriate tools to deal with any kind of vehicle, so be sure you find a reputable company that offers these types of tools.
Key FOBs
As the name suggests, key FOBs house the 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 push to activate features such as door locks, trunk release or fuel flap control. Some fobs also have additional functions that can be controlled by the push of a button like the "smart" key fob that lets you get your car into parking spaces that are difficult to access similar to the Genesis GV60 or Tesla.

While certain replacement key fobs can be programmed with the assistance of a user's manual but you'll usually need an automotive locksmith to get a new one programmed if yours stops functioning. A professional locksmith is more equipped to connect the computer of your vehicle to the OBD port on the steering wheel.
The majority of key fobs come with security features to make it more difficult for criminals to replicate and clone the signals they transmit. Certain key fobs feature 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 to gain access to your vehicle.
In many cases you can purchase an alternative key fob from the dealership or another retailer and have it programmed by your locksmith in your car to work with your particular vehicle. This is because most of the major US and Asian car makers have key fob programming protocols with third-party companies who create the tools locksmiths for auto employ to program keys for their customers.
While some of the aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths do not recommend using them as they are likely to function poorly or not at all. Instead, they suggest purchasing fobs specifically designed for your vehicle so that you can be certain they'll function correctly and are less prone to issues like interference or incompatibility. This will save you money over the long term by avoiding expensive repairs or replacing the fobs.

It needs to be programmed by a locksmith, mechanic or dealer to function. Key fobs come with built-in security features that stop hot-wiring (like in a film) and the car won't start if it doesn't have the right key.

The cost of the car key fob is depending on the model and type of key, but it is typically between $85 to $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 use a special software system to connect to the car's onboard computer. The software blocks access to unauthorised users by only allowing keys programmed for a specific vehicle to work. This means that if you get your keys replaced, you'll need to have the new key fob programed to the car for it to work.
This is done by using a tool for programming car keys that is compatible with the brand of your vehicle. This tool allows the locksmith to connect to the OBD port (OBD) in the vehicle and then enter an programming mode. The key programming tool could be a simple handheld device or a more expensive one that can do a wide range of things beyond just key programming (like reading and cloning Eeprom files within the ECU).
While some may try to program their own keys with these tools, this is an activity best left to a professional auto locksmith. It's easy to make a mistake with the software systems if you don't understand the nuances. This could lead to damage.

You can also program new keys using the EEPROM. It is more complex and requires a thorough understanding of electronic systems. This is why it's best left to a professional that has years of expertise working on these types of systems.
Locksmiths can program a key quickly using onboard programming. It takes as little as an hour if everything is completed correctly. If the key isn't in the proper situation or the procedure isn't followed exactly, it can take as long as a half hour.
There are numerous key programmer scanners which can work with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due to their wide range of models for vehicles. However, no system can be programmed for every vehicle in existence.
