Saab Key Programming

saab 93 key fob cars built since about 1994 have an immobilizer system that is based on codes for keys. The addition of a key requires a new transponder, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

It can be costly. This is why it is important to always have a spare key at hand.

Transponder key

The transponder is a key with an electronic chip. The chip sends a signal when the key is put into the ignition. The car then examines the signal to see whether it matches that of the key. If the signals match the car will then unlock and begin. This is a great way to stop car theft and keep your car secure from thieves.

Transponder keys are a favored feature in cars, but you should be aware they're not as secure as traditional metal keys. The metal portion of a traditional key can be easily cut and copied, whereas transponders have an electronic chip that protects it. This chip contains a unique code programmed into the car's computer to identify it.

The car will recognize the saab keys keyfob and permit it to be turned on. The car can only recognize the key fob if it has an unmodified chip and programmed to match. The car won't start if the key is not programmed to match.

It is vital to have a spare saab 9-3 key fob programming key. This is particularly important especially if you reside in a rural area where there are many car thieves. The good news is that it's possible to get a replacement key for your Saab without needing to visit an auto dealer and pay the high prices that they demand. In most instances, you can get a brand new key made right on the spot at a fraction of the price of what you would pay at an auto dealer.

Key for Wired

saab key replacement cars are usually delivered with two keys. If you have only one, you need to purchase an additional key as fast as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This could be expensive particularly if you are purchasing a used vehicle.

The next step is to wire the wires for the column and row to the microcontroller. This is the most difficult part of the project and will require a great deal of soldering. There is no standardized way to do this, but it is essential to determine how you will route and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has 5 rows and 17 column.

After the rows and column are soldered together after which it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins that are used for key switches from current and prevent them from being shorted. A diode allows current to flow in one direction, and has a an indicator of black color that indicates the direction current will flow.

Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could assist customers at the shop or DIY customers in some cases create replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jump starting the battery

A lot of people keep a set of jumper cables in their trunks for emergency situations however, jumping a battery on modern vehicles might not be the best option. These cars have a variety of computers and digital devices that communicate with each other. A surge in voltage while a battery is hooked up to another battery could fry these components and render your vehicle undriveable.

Start the vehicle you are using and allow it to run for approximately two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of 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 car's hood. The engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery as it could spark an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, you should start the vehicle and let it run about five minutes. Then disconnect the cables in reverse. Keep in mind that the battery on the Saab 9-3 will be charged when you drive, so it could take a while to get the battery down. You should invest in an additional key fob when you can. Replacing the only one that works requires the installation and programming of a new computer chip.

replacement saab key Case

Saab owners typically only have one car key, and if that is Lost Saab Keys, they'll be charged. The reason is that it's costly to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is recommended to have a backup key in the event of theft or any other catastrophe the best solution is to purchase a second key as soon as you are able to. Don't buy a secondhand key even if it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't be effective and are almost guaranteed to fail at the critical moment.

The dealer will charge the highest 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 having to replace the entire system. This could help you save money. It's also a lot cheaper than waiting until you lose your one key.
