Transponder Chips

The majority of newer cars have transponder chips in order to prevent theft. These are tiny computer microchips that emit radio waves of low-level. They are equipped with a unique digital serial number that authenticates the key to your vehicle when it is connected to the ignition barrel.

The antenna is programmed to detect the particular frequency of the chip within the key. The car's computer onboard will recognize that the key is valid and allow the fuel to flow, then power up the starter or start it.

If you decide to replace your keys, you'll need to program the new key fob into the car for it to function.

The most popular method to accomplish this is using an auto key programming tool that is compatible with the brand of the vehicle. This tool allows a locksmith to connect to the OBD port on the vehicle, and then enter the programming mode. The key programming tool can be a simple handheld device or a high-end one that is capable of performing many things beyond just key programming (like reading and cloning the eeprom files in the ECU).

You can also program new keys using the EEPROM. It is more complex and requires an in-depth understanding of how electronic systems operate. This is why it should be left to a professional who has extensive experience working on these types of systems.

Onboard programming is the quickest method for locksmiths to program an entirely new key. It can take as little as one minute if everything is completed correctly. If the key isn't in good working order or the procedure isn't followed precisely, the procedure could be as long as half an hour.

There are a variety of key programmer scanners that support different makes and models of vehicles. Both the Smart Pro and Autel IM608 Pro have become extremely popular with locksmiths due to their wide selection of vehicle models.
