Saab cars produced from 1994 have an immobilizer system that relies on coded keys. To add an additional key, you need a new transponder and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

It can be costly. This is why you should always have a spare key on hand.

Transponder key

The transponder key comes with an electronic chip that sends a signal to car when it is placed in the ignition. The car will then check the signal to see whether it is the same as the one on the key. If the signals are identical the car will then unlock itself and begin. This is an excellent way to guard your car against theft.

Transponder keys may be an extremely popular accessory for cars, but they're not as safe as traditional metal keys. The metal part of the traditional keys can be easily cut and copied, however the transponder is protected by an electronic chip that protects it. This chip has an unique code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. The car can only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. The car won't start if the key is not programmed to match.

It is crucial to have a spare Saab 93 Replacement Key key. This is especially true when you live in a rural area with numerous car thieves.

This is because if it's lost saab key, the car will need an entirely new CIM and the locking cylinders replaced. This can be expensive especially for used vehicles.

The next step is connecting the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a good amount of soldering. There is no standard method to do this, but it is important to think about how you will route and solder the rows and columns. There are 22 microcontroller wires and pins to connect to this keyboard. It has five rows and 17 columns.

Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, you need to place a diode over each key switch pin and solder it. This will shield the pins from current, preventing them from being shorted. A diode allows current to only flow in only one direction. It has a visual indicator of a black line that indicates the direction in which current will flow.

Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may help customers in the shop, or even DIY customers in certain cases create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into the OBD port and guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

Most people keep a set in their trunks to start a vehicle in the event of an emergency, but it might not be a good idea for cars with more modern technology. These vehicles are equipped with computers and digital devices which communicate with each other. A voltage spike when the battery is connected to another one could cause damage to the parts making your car unusable.

Connect the cables to the vehicle that is operating. Allow it to 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 a clean, unpainted metal surface underneath the disabled car's hood--the engine block is an excellent choice. Don't connect the black cable to the negative terminal on the dead battery because this could cause an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, turn on the disabled vehicle and let it run for about five minutes before you disconnect them in reverse order. Be aware that the battery of the Saab 9-3 will be charged when you drive, and it could take a while for the battery to come back to its original level. You should consider purchasing a second key fob, as soon as possible. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

saab 9 3 key replacement owners typically only have one car key, and if it is lost, they'll be charged. It's expensive to add the key and also requires replacing the CIM or TWICE for older models. It's best to have a second key in case of theft or any other catastrophe, and the best way is to buy an extra key as soon as you are able to. However, don't purchase a secondhand key even if it's "new." Keys that are claimed to be new from aftermarket sellers will not work and are almost guaranteed to fail in the most critical moment.

The dealer will charge you top 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 replacement key without replacing the entire system. This can save you a significant amount of money. It's less expensive than waiting until you lose the sole key.
