Automotive Locksmith Key Programming

Modern cars require some type of key programming. Based on the model and make, the process may be as simple as using a spare key to programme the computer onboard, or as complicated as EEPROM or OBD2 programming.

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

Transponder Chips

Transponder chips are in a variety of newer vehicles to stop theft of cars. These are tiny computer microchips which emit low-level radio waves. The microchips have a unique serial number that authenticates your keys when you plug it 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 huge deal of money since they don't have to replace their vehicles.

In the past, thieves used an ordinary screwdriver to force the ignition switch in your car into the "on" mode or even wire it hot to evade 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 transmits the signal which is picked up by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed to detect the specific frequency of the chip inside the key. The car's onboard computer will then recognise that the key is genuine and allow fuel to flow, turn the starter or start it.

Depending on the manufacturer certain vehicles can only recognize a specific type of transponder chip. It is therefore important that your locksmith for cars is equipped with the correct equipment to program a car key your car's keys and remotes.

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

While some replacement keys can be programmed with the help of a user manual however, you'll typically require an auto locksmith to get a brand new one programmed in case yours stops functioning.

The majority of key fobs come with security features to make it harder for attackers replicate and clone the signals that they transmit. Certain key fobs come with pseudo-random code generators which generate a new unlock code every time you press the button.

Key fobs are more complicated than a traditional mechanical key, which is why they are usually in the hands of a reputable, professional auto locksmith. The cost of a key fob will differ based on the vehicle model and the key type however, they generally cost between $85 to $400. This includes the cost of labor to program the key fob as well as the costs for any required replacement parts.

Programming EEPROM is another method that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. It's best to leave it to a professional who has knowledge of these systems.

Locksmiths can program keys quickly with onboard programming. When everything is done correctly it could take just one minute. If the key is not in the right condition or the procedure isn't followed exactly, the process can be as long as half an hour.
