10 Things Everybody Hates About Saab Ignition Key Replacement
Saab Key Programming

Saab cars built since about 1994 have an immobilizer system built on coded keys. The addition of a key requires an entirely new transponder and programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this can be extremely expensive. This is why it is important to always keep a spare key in your possession.

Transponder key

The transponder is a piece of key that is equipped with an electronic chip. This chip sends a signal when the key is inserted into the ignition. The car then analyzes the signal to determine whether it is identical to the one that is in the key. If the signals are in sync then the car will be able to unlock and begin. This is a great way to avoid auto theft and keep your car secure from thieves.

Transponder keys are an increasingly popular feature in automobiles, but it is important to know that they aren't as secure as traditional metal keys. The metal component of the traditional key can easily be cut and copied, whereas transponders have an electronic chip that guards it. This chip contains a unique code programmed into the car's computers to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it is only able to do so if the key fob is unmodified and has a chip that has been programmed to match. Otherwise, the car will reject the key and refuse to start.

It's crucial to ensure that you have an extra key for your Saab. This is particularly important especially if you reside in a rural area where there are many car thieves. The good news is that you can get a replacement key for your Saab without needing to visit a dealership and pay the high prices that they demand. In most instances, you can get a new key created on-the-spot at a fraction of the cost you'd pay at an auto dealer.

Key for Wired

Saab cars typically come with two keys when they're new. If you have only one, you should get an extra key as soon as you can. This is because if you lose it and the car needs a new CIM and the locking cylinders replaced. This can be costly particularly for used cars.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most challenging part of the project and will require a large deal of soldering. There isn't a standard way to accomplish this, however it is important to think about how you will route and solder the rows and columns. 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 the time to connect them to key switches. To do this, put a diode on each key switch pin and solder it. This will shield the pins from current, preventing them from being shortened. A diode only allows current to flow in one direction, and it has an indicator of black color that indicates which way the current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in certain cases program replacement keys and restore lost immobilizer data Sanabria says. The tools connect to OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jump-starting the battery

Most people keep a set of jumper cables in their trunks for emergencies, but jumping a battery on modern automobiles might not be the best choice. These vehicles have many computers and digital devices that communicate with each other. A surge of voltage when the battery is connected to another battery could damage the components making your car inoperable.

Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach saab key programming near me on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood. The engine block would be an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite the gasoline inside the engine compartment.

Once the cables are connected the vehicle you are not using and let it run for approximately five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 will be recharged while you drive. It will take some time for it to return to its original state. It's a good idea to purchase a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and a special program to convince the system that your lost keys are not trying to steal the car.

Replacement Case

Many Saab owners have only one key for their vehicle and if they lose that they'll be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE for older models. It is best to have a spare key in the event of theft or any other catastrophe and the best option is to purchase an additional key as soon as you can. But don't buy a used key, even if it's "new." Keys that are claimed to be new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the most critical moment.

The dealer will charge the highest dollar if you only have one working key. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept the new key without having to replace the whole system. That can save you a significant amount of money. It's cheaper to do this than wait until you lose your only key.
