Saab Key Programming

Saab cars built since 1994 utilize an immobilizer that relies on key codes. A new transponder is required in order to enable the addition of an extra key, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

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

Transponder key

The transponder can be described as a key equipped with an electronic chip. The chip sends a signal when the key is placed in the ignition. The car then checks to see whether the signal matches the one on the key. If the signals are the same, the car will unlock itself and start. This is a great method to guard your car against theft.

Transponder keys could be an extremely popular accessory for cars, but they're not as safe as traditional keys made of metal. The metal part of the traditional key can be easily cut and copied, whereas transponders are protected by an electronic chip that safeguards it. The chip has a unique code that is inserted 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 has been programmed to match. The car will not start when the key isn't programmed to match.

It's essential to ensure that you have a spare key for your Saab. This is especially important when you live in a rural area, where there are numerous car thieves. You can get a brand new key for your saab replacement keys by visiting the dealership without paying high cost. You can have a replacement key made on the spot for less than half the price you'd pay at dealerships.

Key for Wired

Saab cars are typically delivered with two keys. If you only own one, you should purchase an additional key as quickly as you can. This is because if you lose it the car will require an entirely new CIM and the locking cylinders replaced. This could be expensive, especially if you are buying a used car.

The next step is to wire the row and column wires to the microcontroller. This is the most challenging part of the project and will require a large deal of soldering. It's not a standard way to do it, but you should think about how to connect and solder each column and row. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 column.

Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, put a diode across each key switch pin and solder it. This will shield the pins from current, preventing them from being shorted. A diode can only allow current to flow in one direction, and has a an indicator in black that indicates which way the current will flow.

Sanabria says that some of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 can assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data. 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

The majority of people have an assortment of tools in their trunks to jump-start their vehicle in the event of an emergency, but it might not be the best idea for vehicles that are newer. These vehicles are equipped with numerous digital and computer systems that communicate with one another. A surge of voltage when a battery is connected to another could cause damage to the components making your car unusable.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood--the engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite the gasoline in the engine compartment.

Once the cables are connected, start the vehicle and let it run for approximately five minutes. Then, disconnect the cables in reverse. Keep in mind that the battery on the saab car key 9-3 will be charged when you drive, and it could take a while for the battery to come back down again. It is a good idea to invest in a spare key fob as soon as you can, because replacing the one that works requires the installation of a new computer module and special programming to convince it that your missing keys aren't trying to steal the car.

Replacement case

saab 9-3 replacement key owners typically only have one car key, and if it is lost, they'll be charged. The reason for this is that it's expensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other disaster it is advisable to have an extra key. However, don't purchase a secondhand key even when it's "new." Claimed-new keys from a second-hand store will not be effective and are almost guaranteed to fail at the critical moment.

The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM to get it ready to accept a new key without having to replace the entire system. This can save you lots of money. It's more affordable than waiting until you loose the only key.
