Saab Key Programming

The issue is that this could be very costly. This is the reason why you should always have a spare key available.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal back to the car when it is placed in the ignition. The car then checks to see whether the signal matches the one on the key. If the signals match then the car will be able to unlock and start. This is a great way to prevent car theft and keep your vehicle secure from thieves.

Transponder keys are an extremely popular accessory for cars, but they are not as secure as traditional metal keys. While the metal parts of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. This chip contains an unique code which is programmed into a car's computer in order to identify it.

The car will recognize the saab 93 key replacement keyfob, and allow it to turn on. The car can only recognize the key fob when it has an unmodified chip and programmed to match. The car will not start in the event that the key is not programmed to match.

If you have only one, it is best to acquire an extra key fob as soon as is possible in case you lose it the car will require the replacement of a CIM unit and the locking cylinders need to be replaced. This can be expensive especially for used vehicles.

The next step is to wire the wires for the column and row to the microcontroller. This is the most laborious aspect of the project and it will require lots of soldering. There isn't a standard way to do this, but it's important to plan out the route you'll take and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

Once the rows and columns are soldered, it's the time to connect them to the key switches. Solder a diode to each key switch pin. This will protect the pins from current, and prevent them from getting shorted. The diode will only allow current to flow in one direction, and has a an indicator in black that indicates the direction in which current will flow.

Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could aid shop customers or DIY customers in some cases program replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.

Jump starting the battery

The majority of people have a set of jumper cables in their trunk for emergency situations however, jumping a battery in newer vehicles might not be the most efficient option. These cars have a variety of computers and digital devices that communicate with each other. A voltage surge while a battery is hooked up to another can fry these components and leave your car unable to drive.

Connect the cables to the vehicle that is working. Let it run for two minutes. 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 of the black cable to an unpainted, clean metal surface underneath the disabled car's hood. The engine block is a good choice. 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 inside the engine compartment.

Once the cables are connected, start the vehicle that has been disabled and allow it to run for around five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 will be recharged as you drive. It takes a while for it to drop back down. You should invest in another key fob as soon as possible. The replacement of the one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners only have one key for their car and if they lose that they'll be charged. The reason is that it's costly to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft, or any other catastrophe it is best to have a spare key. But don't buy a used key, even when it's "new." Claimed-new keys from aftermarket sellers will not perform and are almost certain to fail at the crucial moment.
