Transponder key
The transponder is a piece of key that has an electronic chip. This chip sends a signal when the key is put in the ignition.

This is because if the key is lost the car will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially if you are purchasing a used vehicle.
The next step is connecting the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a large deal of soldering. There is no standard method to accomplish this, but it is important to think about the route you'll take and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has five rows and 17 columns.
After the rows and column are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, preventing them from being shortened. A diode permits current to only flow in one direction. It features a visual indicator, a black band, that shows the direction in which the current will flow.
Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY users in some cases programme replacement keys and recover lost immobilizer data, Sanabria says. The tools connect to OBD ports and guide the user through each step which makes the process much easier than replacing the car's computer.
Jump-starting the battery
Most people keep a set of jumper cables in their trunks for emergencies, but jumping a battery on newer vehicles might not be the best idea. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A voltage spike when a battery is connected to another battery could damage the components and render your vehicle unusable.
Start the vehicle you are using and allow it to run for approximately two minutes before connecting the cables to the battery that is not working. Attach the red clip on the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged car's hood. The engine block would be a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline inside the engine compartment.

In the event of theft or any other calamity it is best to have an extra key. Don't purchase a used key, even it's "new." Keys that are claimed-new from a second-hand store will not work and are likely to fail at the crucial moment.
The dealer will charge you the highest dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to be able to accept a new key without having to replace the entire system. This can save you a significant amount of money.
