Automotive Locksmith Key Programming

Most modern-day cars require some type of key programming. Depending on the vehicle's make and model, the process can be as simple as onboard programming with a spare working key or as complicated as EEPROM or OBD2 programming.

The majority of US and Asian car makers have programming protocols that they share with auto tool manufacturers in order to create hardware and software for locksmiths in the automotive industry to use.

Transponder Chips

Transponder chips are used in a variety of newer vehicles to stop theft of cars. These are tiny computer microchips that emit radio waves of low-level. They have a unique serial number which authenticates your keys when you insert it into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been an immense success in stopping auto theft. This technology has also saved car owners a great deal of money by not having to replace their vehicles.

The basic idea behind the transponder system is to make it difficult for thieves to open the doors of your car without the proper key. In the past, thieves would use an ordinary screwdriver to force the ignition switch of your vehicle into "on" mode or even hot-wire it in order to get around the system. Transponder chips have dramatically reduced the number of thefts.

When you insert the transponder key into the ignition the signal is received by an antenna that is concealed around the barrel. This antenna is programmed with the frequency of the chip within the key. The car's computer onboard will detect that the key is valid and allow the fuel to flow, then power up the starter or start it.

Certain vehicles only recognize a certain type of transponder chips, 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.

For instance, a "smart key" that allows you summon your car to parking spaces, like a Tesla or Genesis GV60.

While some replacement key fobs can be programmed by you with the assistance of a user's manual but you'll usually require an automotive locksmith to get a brand new one programmed if yours stops functioning. This is because a professional has the equipment that is specialized and access to the programming tools needed to connect your car's computer to the OBD (OBD) port that is located under 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 that they transmit. Some key fobs have pseudo-random code generators, which generate a different unlock code every time you press the button. This is to prevent attackers from capturing and playing back the unlock signal to gain access to your car.


In some cases you can purchase the replacement keyfob at a dealership or another retailer. The locksmith you choose to use will then program it to work with your car.

The cost of the car key fob can vary according to the type and model of key, but it is generally between $85 to $400. This includes labor costs to program the keyfob as well as any replacement parts.

These car key fobs are more complicated due to the fact that they use software that interacts with the computer onboard of the car. The software blocks unauthorized access by allowing the key to function if it has been programmed to the car in question. This means that if you need your keys replaced, you'll need to have the new key fob programmed to the car to function.

This tool lets the locksmith connect to the OBD port (OBD) within the vehicle and then enter the programming mode. Key programming tools can be a handheld device that is inexpensive device or a fancy one that can perform many things beyond key programming (like reading and cloning the Eeprom files within the ECU).

You can also program new keys by using the EEPROM. It is more complicated and requires a thorough understanding of electronic systems. This is why it should be left to a professional that has extensive experience working on these types of systems.

Onboard programming is the most efficient method for locksmiths to program a new key. If everything is done correctly it can take as little as one minute. If the key isn't in the proper condition or the procedure isn't followed exactly, it can take up to a half hour.
