The first step in reprogramming a transponder is to ensure that the key is equipped with an electronic circuit board or transponder of the proper type. The key must also be compatible with the vehicle's onboard computer and include the key ring properly positioned around the ignition barrel.
This type of reprogramming is typically done using a transponder cloning machine, which is able to copy a specific circuit board or transponder. This equipment is available from some major blank manufacturers as well as experts in reprogramming. The cloning machine must car key program near me be able to read the information transmitted by each transponder that is being copied. Some cloning devices can be upgraded and can be used to copy the latest transponders when they are released.

A lot of automakers now require keys to transmit the unique VIN number of the vehicle as well as the transponder code. These additional security measures require specific key programming procedures that are usually not available to independent mechanics unless they have access to a dealer-only tool such as Autel's IM608 Immobilizer Scan Tool or Launch Tech's X-Prog3 scanner for immobilizers.
When programming a new key it is important to select the right PIN that is easy for you to remember but difficult for someone else to guess.
