It has 5 rows and 17 columns.

After the columns and rows are soldered together, it is time to connect the key switches. To do this you must place an inverter over each pin of the key switch and solder it. This will shield the pins from current, and prevent them from getting shorted. The diode allows current to only flow in only one direction. It comes with a visual indicator of a black line that shows which way current will flow.

Some of the tools offered at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- can assist customers at the shop or DIY users in some cases programme replacement saab key keys and recover the lost immobilizer's data, Sanabria says. The tools plug into OBD ports and guide the customer through each step and make the process more straightforward than replacing the car's computer.

Jump-starting the battery

Most people keep a set of jumper cables in their trunk for emergency situations, but jumping a battery in newer automobiles might not be the most efficient option. These vehicles are equipped with digital and computers that communicate with each other. A surge in voltage when a battery is connected to another can fry the components, rendering your car undriveable.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface under the hood of the disabled car. The engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery as it could ignite an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, you can start the disabled vehicle and let it run for approximately five minutes before disconnecting them in reverse order. The battery in the Saab 9-3 will charge as you drive. It may take a while it to recharge again. It is recommended to purchase an additional key fob when you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.

It is best to have a backup key in the event of theft or any other catastrophe, and the best way is to purchase an extra key as soon as you are able to. But don't buy a used key even it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't work and are almost guaranteed to fail at the critical moment.

Most locksmiths can't help you when you only have one working key and the dealer will charge you for the cost of replacing the computer in your vehicle to make a replacement. However, we can reset and re-program your computer's EEPROM to accept the new key, without replacing the entire system. This could help you save a significant amount of money. It's also a lot cheaper than waiting until you lose your only key.
