14 Common Misconceptions About Saab Ignition Key Replacement

Saab Key Programming

saab key fob programming cars manufactured since 1994 utilize an immobilizer system that is based on a set of keys. The addition of a key requires a new transponder, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The problem is that this can be very expensive. Always keep an extra set of keys at hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. This chip sends out a signal when the key is placed in the ignition. The car checks to see if the signal matches the one on the key. If the signals are the same the car will then unlock itself and begin. This is a great method to guard your car against theft.

Transponder keys are an increasingly popular feature for cars, but they're not as safe as traditional keys made of metal. While the metal parts of a conventional 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 the car's computer in order to identify it.

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

It is essential to have a spare Saab key. This is especially important especially if you live in a rural area with many car thieves. The good news is that you can obtain a replacement key for your saab ignition key replacement without having to go to a dealership and pay the high costs that they charge. In the majority of cases, you can have a new key made on-the-spot at a fraction of the cost of what you'd pay at the dealer.

Wired key

Saab cars are usually delivered with two keys. If you have only one, it is a good idea to get an additional key fob as soon as you can since if you lose it, the car will require the replacement of a CIM unit and the locking cylinders will need to be replaced. This can be expensive especially for cars that are used.

The next step is to connect the column and row 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 common way to go about it, however, you should consider how you will connect and solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode to each key switch pin. This will shield the pins from current, thus preventing them from being cut off. A diode allows current to only flow in one direction. It has a visual indicator that is black, that shows which way current will flow.

Sanabria says that a few of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508, can help shoppers 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

A lot of people keep a set of jumper cables in their trunk in case of emergency, but jumping a battery in newer cars might not be the best option. These vehicles are equipped with computers and digital devices which communicate with one another. A voltage spike when a battery is connected to another one could cause damage to the parts making your car inoperable.

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 have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface under the hood of the disabled car. The engine block is a great choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite gasoline in the engine compartment.

After the cables have been connected, you can start the vehicle and allow it to run for around five minutes. Then, disconnect the cables in reverse. Be aware that the battery in the saab replacement key 9-3 gets recharged when you drive, so it will take a while for the battery to come back to its original level. It is recommended to purchase 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 vehicle and if they lose that key, it will cost them. It's expensive to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It's best to have a spare key in the event of theft or other disaster, and the best way is to purchase an additional key as early as you can. But don't buy a used key, even the case that it's "new." Claimed-new keys from sellers selling aftermarket keys won't be effective and are almost guaranteed to fail in the crucial moment.

The dealer will charge you the most expensive dollars if you only have one working key. However, we can reset and reprogram the computer's EEPROM to accept the new key without having to replace the entire system. That can save you a lot of money. It's also cheaper than waiting until you lose the only key.
