"Ask Me Anything": Ten Responses To Your Questions About Automotive Locksmith Key Programming

Automotive Locksmith Key Programming

Modern automobiles require some kind of key programming. Depending on the car's maker 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.

Most US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, so they can develop hardware or software for locksmiths in the automotive industry.

Transponder Chips

Transponder chips are found in a variety of newer vehicles to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number which authenticates your key when you insert it into the ignition barrel. If your vehicle does not recognize the signal, the engine will be shut down. This technology has proved to be an immense success in stopping auto theft. This technology has also helped car owners save a good deal of money as they do not have to purchase new cars.

Transponder chips have dramatically reduced the number of thefts.

When you insert a transponder keys into the ignition, it will transmit the signal which is detected by a hidden antenna circling the barrel of the ignition. This antenna is programmed to read the specific frequency of the chip within the key. The computer onboard of the car will then recognize the key as valid and will allow fuel flow, power the starter or start the engine.

This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.

In most cases, you can purchase an additional key fob at the dealer or other retailer and then have it programmed by a locksmith for your vehicle to be compatible with your specific vehicle. This is because the majority of the major US and Asian automobile manufacturers have key fob programming protocols with third-party companies that make the tools that locksmiths use to program their customers' keys.

While some aftermarket key fobs are advertised as compatible with all vehicles, most automotive locksmiths don't recommend using them because they're likely to work poorly or not at all.

This will save you money in the long run by avoiding costly repairs or replacing your fobs.
