Transponder key

The transponder is a key equipped with an electronic chip. This chip sends out a signal when the key is inserted in the ignition. The car then examines the signal to determine whether it matches that of the key. If the signals are the same it will open itself and start. This is a fantastic way to safeguard your car from theft.

Transponder keys are a favored feature in vehicles, but you should be aware that they are not as secure as traditional keys made of metal. While the metal part of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. The chip has a unique code that is programmed into a car's computer order to identify it.

The next step is to connect the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There's no standard way to do it, but you need to consider how you will route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the pins of the key switch from current and also prevent them from being shorted. A diode permits current to only flow in only one direction. It has a visual indicator with a black band that shows the direction in which the current will flow.

A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or DIY users in some cases create replacement keys and restore lost immobilizer data Sanabria says.

Jumpstarting the battery

A lot of people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery on newer vehicles may not be the best option. These vehicles are equipped with a number of computers and digital devices that communicate with each other. A surge in voltage when batteries are connected to another can fry the components, rendering your car undriveable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of the disabled vehicle. The engine block is an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline inside the engine compartment.

Once the cables are connected, turn on the vehicle you are not using and let it run for about five minutes before disconnecting the cables in reverse order.

Replacement case

Many saab key fob repair owners have only one key for their vehicle and if they lose it, they'll be charged. The reason is that it's not cheap to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is recommended to have a second key in case of theft or any other catastrophe, and the best way is to buy an extra key as early as you can. But don't buy a used key even if it's "new." Keys that are claimed as new from aftermarket sellers will not be effective and are almost guaranteed to fail at the crucial moment.
