Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on the vehicle's make and model, the process can be as easy as onboard programming using a spare key that works or as complex as OBD2 or EEPROM programming.
The majority of US and Asian automakers have a programming protocol that they share with auto tool manufacturers, so they can design software or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with transponder chips to stop car theft. These are tiny computer microchips that emit radio signals at a low level. They have a unique serial number which authenticates your key whenever you plug it into the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has proven to be an immense success in stopping auto theft. It also saves many car owners a lot of money as they don't need to replace their vehicles.
The principle of the transponder system is to make it impossible for thieves to get into your car without the right key. In the past, thieves used an ordinary screwdriver to force the ignition switch of your vehicle into "on" mode, or wire it hot to get around the system. These types of thefts have drastically reduced with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will transmit the signal which is received by a hidden antenna around the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The onboard computer of the car will recognize the key as valid and will allow fuel flow and power the starter to start the engine.
Certain vehicles only recognize a specific type of transponder chip depending on the manufacturer. It is therefore important that your locksmith for cars is equipped with the appropriate equipment to program your car's keys and remotes.
A reputable locksmith for cars should have a multi-vehicle key programming tool that can work on many different models and car brands. This is a cheaper solution than buying specific tools for each type of vehicle. There are also specially-designed key programming devices for automotive that can only be used on specific models of vehicles however they are not as popular. The top automotive locksmiths have the right equipment to tackle any type of vehicle, so be sure you choose a reputable firm that has these types of tools.
Key FOBs

They also have buttons that you can push to activate features such as door locks, trunk release or fuel flap control. Certain fobs can be controlled with the press of buttons. For instance an "smart key" that lets you call your car to parking spaces, like a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you using the help of a user manual, you'll often require an auto locksmith to get a brand new one programmed if the one you have isn't working. A professional locksmith is more equipped to connect the computer of your car via the OBD port located under the steering wheel.
The majority of key fobs today include security features that make it difficult for attackers to duplicate or duplicate the signals they transmit. These include pseudo-random sequence generators that generate an entirely new unlock code every time you press the button on your key fob. This blocks attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many instances you can purchase an additional key fob at the dealer or from another retailer and then have it programmed by your locksmith in your car to fit your particular vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party firms who make the tools used by auto locksmiths to program their customer's keys.
While some aftermarket key fobs are advertised as compatible with all vehicles however, the majority of locksmiths for automotive don't recommend using them since they are likely to function poorly or not at all. They recommend buying fobs made specifically for your vehicle so that they work correctly and are less susceptible to issues such as interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing your fobs.

The cost of a key fob can vary based on the vehicle model and the type of key however they usually cost between $85 to $400. This includes the labor cost to program the keyfob as well as any 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 prevents unauthorised access by only permitting keys that have been 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 programmed to the car for it to work.
The most popular method to accomplish this is using a car key programming tool that is compatible with the model of the vehicle. This tool allows locksmiths to connect to the OBD port in the vehicle and then enter programming mode. Key programming devices can be an handheld device that is inexpensive or one that is extravagant and can do more than just programming keys (like reading the eeprom file inside the ECU).

You can also program new keys using the EEPROM. 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.
Onboard programming is the fastest way for a locksmith to program an entirely new key. It takes as little as an hour if everything is executed correctly. However, if the key isn't placed in the correct state or the procedure isn't strictly followed, it could take as long as a half hour.
There are a variety of key programmer scanners available that can be used with different vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both very well-liked by locksmiths due to the fact that they support a broad range of automobile models.
