Saab Key Programming

Saab cars that were built prior to 1994 come with an immobilizer system made up of coded keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that this can be very expensive. This is why you should always have a spare key at hand.

Transponder key

The transponder keys are keys with an electronic chip that transmits a signal to the car when it is placed in the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals are the same, the car will unlock itself and begin. This is a great way to avoid car theft and keep your car safe from thieves.

Transponder keys are a popular feature in automobiles, however you should be aware they aren't as secure as traditional keys made of metal. The metal component of a traditional keys can be easily copied and cut, but transponders have an electronic chip that protects it. The chip has a unique code that's programmed into a car's computer order to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and programmed to match. The car will not start if the key is not programmed to match.

It is crucial to have a spare saab car key key. This is particularly important if you reside in a rural region that has many car thieves. You can obtain a replacement key for your Saab by going to the dealership without paying pricey costs. In the majority of instances, you can get a brand new key made right on the spot for less than half the cost you'd pay at the dealer.

Key for Wired

Saab cars typically come with two keys upon purchase. If you have only one, it's recommended to purchase an extra key fob as soon as is possible, because if 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 cars.

The next step is to connect the row and column wires to the microcontroller. This is the most difficult part of the project and requires a significant amount of soldering. There is no standardized way to do this, but it is essential to determine the routes you'll use to solder the columns and rows. There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 columns.

After the rows and column are joined then it's time to connect the key switches. To do this, you need to place an inverter over each key switch pin and solder it. This will shield the pins from current, preventing them from getting shorted. A diode allows current to only flow in one direction. It features a visual indicator of a black line that shows the direction in which the current will flow.

Sanabria says that some of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jumpstarting the battery

The majority of people have an item in their trunk to jump-start their vehicle in the event of an emergency, but it might not be a good idea for newer cars. These vehicles are equipped with a number of digital and electronic devices that communicate with each other. A surge in voltage when the battery is connected to another can fry these components and render your car unable how to get a saab replacement key drive.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clear, unpainted metal surface under the hood of the affected car. The engine block is a good alternative. The black cable should not be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite the gasoline that is in the engine compartment.

Once the cables are connected, you need to begin the car and let it run about five minutes. Then disconnect the cables in reverse. Be aware that the battery of your saab 93 key fob 9-3 is charged during your drive, which means it can take a while for the battery to come down. You should consider purchasing an additional key fob when you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.

Replacement case

Many Saab owners have only one key for their car and if they lose that the cost will be. It's expensive to buy a key and requires replacing the CIM or TWICE in the case of older models. It's recommended to have a backup key in the event of theft or other disaster and the most effective way is to buy an extra key as quickly as you can. Even if the key is "new" it won't work.

The dealer will charge you top dollar for only one working key. We can, however, reset and reprogram the computer's EEPROM to prepare it to accept a new key without replacing the whole system. This could help you save a significant amount of money. It's cheaper to do this instead of waiting until you lose your only key.
