Automotive Locksmith Key Programming

Modern cars need some form of key programming. Depending on the vehicle's make and model, the process can be as simple as programming onboard using a spare working key or as complex as EEPROM or OBD2 programming.

Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can create tools or hardware for automotive locksmiths.

Transponder Chips

Most newer cars use transponder chips to stop car theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been extremely successful in preventing car theft. This technology has also helped cheap car key programming owners save a good amount of money by not having to buy new vehicles.

Transponder chips have drastically reduced the number of thefts.

When you insert the transponder keys into the ignition the signal is received by an antenna that is hidden within the barrel. The antenna is programmed to match the frequency of the chip inside the key. The car's onboard computer will recognize that the key is valid and allow fuel to flow, turn up the starter or begin it.

Some vehicles only recognize a certain type of transponder chip, depending on the manufacturer. This is why it's crucial to make sure that your locksmith for automotive has the appropriate equipment to program your car's keys and fobs properly.

Key FOBs

A professional locksmith is more equipped to connect the computer of your vehicle to the OBD port under the steering wheel.

Today, most key fobs include security features that make it difficult for hackers to clone or replicate the signals they transmit.
