The Ultimate Cheat Sheet On Automotive Locksmith Key Programming
Automotive Locksmith Key ProgrammingModern cars need some form of key programming. Based on the car's make and model, the procedure can be as easy as onboard programming using an extra working key or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automakers use the same programming protocols as auto tool makers, which means they can develop hardware or software for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves of low-level. They have a unique serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your car doesn't recognise the signal, it will shut down the engine. This technology has been extremely successful in preventing theft of cars. This technology has also helped car owners save a good deal of money as they do not have to buy new vehicles.
The basic idea behind the transponder system is to make it impossible for thieves to start your vehicle without a valid key. In the past, car thieves would simply force your ignition switch to the "on" position using an ordinary screwdriver or use hot wires to disable the system entirely. Transponder chips have dramatically reduced these types of thefts.
When you place the transponder key into the ignition, the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed to match the frequency of the chip in the key. The onboard computer in the car will then recognize the key as valid and allow fuel flow, power the starter or begin the engine.
Some vehicles only recognize certain type of transponder chip, depending on the manufacturer. It is therefore important that your automotive locksmith is equipped with the right equipment to program your car's keys and remotes.
A good automotive locksmith should have a multi-vehicle key programming tool that works with different models and manufacturers of cars. This is a much cheaper option than buying specific tools for each model of vehicle. These aren't as popular but there are automotive key programming tools that can only work on a specific model of vehicle. The top automotive locksmiths have the right equipment to tackle any type of vehicle, so ensure you choose a reputable firm that has these types of tools.
Key FOBs
Key FOBs are programmeable transponder chip devices that allow your vehicle to unlock doors and start the engine using the push of a button. It is also possible to press buttons to trigger features such as door locks, trunk releases or control of the fuel flap. Certain fobs can be controlled with the press of buttons. For example the "smart key" that lets you call your car to parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
You can program spare key fobs by yourself with the help from an instruction manual, however you'll need to contact an automotive locksmith in the event that yours has stopped working. A professional locksmith is better equipped to connect the computer of your vehicle via the OBD port under the steering wheel.
The majority of key fobs are equipped with security features to make it difficult for attackers to clone and replicate the signals that they transmit. They include pseudo-random generators that generate a fresh unlock code each time you press the key fob's button. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In most cases you can purchase an alternative key fob from the dealership or another retailer and have it programmable by your locksmith in your car to work with your particular vehicle. This is because most of the major US and Asian car makers use key fob programming protocols with third-party companies that produce the tools locksmiths for auto utilize to programme keys for their customers.
Certain aftermarket key fobs can be marketed as being compatible with all vehicles. However, professional locksmiths recommend against using them because they are likely to work poorly or not work even work at all. Instead, they suggest purchasing fobs designed specifically for your vehicle, so that you are certain they'll function properly and be less susceptible to issues like interfering or not working. This will save money in the long run by avoiding costly repairs or replacements of your fobs.
Tool for Programming Vehicle Manufacturers'

Key programming devices can be a handheld device that is affordable or sophisticated and capable of doing more than just programming keys (like reading the eeprom file inside the ECU).

You can also program new keys with EEPROM. It is more complicated and requires a deep understanding of electronic systems. It's best to leave it to a professional with expertise with these systems.
Onboard programming is the fastest way for a locksmith to program an entirely new key. When everything is done correctly it could take just one minute. However, if the key isn't in correct condition or the procedure isn't strictly followed, it could take up to a half hour.
There are many website key programmer scanners on the market that work with various car models and makes. The Smart Pro and the Autel IM608 Pro are both popular with locksmiths since they can be used with a variety of vehicle models. The system cannot program every vehicle. Furthermore, these systems cost a lot. It's a good idea purchase a programer that will get regular updates as the manufacturer releases new technologies.
