Transponder key

The transponder key is a key equipped with an electronic chip. It transmits a signal to the car when it is placed in the ignition. The car will then check the signal to determine whether it is identical to that of the key. If the signals are in sync the car will then unlock and begin. This is a fantastic way to protect your vehicle from theft.

There is no standardized way to accomplish this, however it's important to plan out how you will route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the columns and rows are joined then it's time to connect the key switches. To do this, place an inverter over each key switch pin and then solder it. This will shield the pins that are used for key switches from current and also prevent them from being shorted. The diode will only allow the flow of current to be in one direction, and it also has a an indicator of black color that shows the direction in which current will flow.

Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help customers in the shop, or even DIY customers in certain cases create replacement keys and restore the lost immobilizer's data, Sanabria says.

Jump starting the battery

A lot of people keep the set in their trunks to jump start a car in case of emergency, but this might not be a good option for vehicles with newer technology.

Start the vehicle you are using and allow it to run for around two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface under the hood of your disabled car. The engine block is a great alternative. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite the gasoline that is in the engine compartment.

After the cables have been connected, you should start the car and let it run for approximately five minutes. Then, disconnect the cables in reverse.

Replacement Case

saab 9-3 key fob programming owners often only have one car key, and if it is lost, they'll be charged. The reason is that it's not inexpensive to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's best to have a backup key in the event of theft or other disaster and the best option is to purchase an additional key as soon as you are able to.
