saab replacement key Key Programming

Saab cars made since 1994 feature an immobilizer system that is based on key codes. In order to add a second key, it requires an entirely new transponder and programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

It can be costly. You should always keep a spare set of keys available.

Transponder key

The transponder keys are keys equipped with an electronic chip. It transmits a signal to the car when it is put into the ignition. The car then checks the signal to see whether it 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 method to prevent car theft and keep your car secure from thieves.

Transponder keys are a popular feature in cars, but you must be aware that they are not as secure as classic keys made of metal. While the metal parts of a traditional key could be cut and copied, a transponder is protected by an electronic chip. This chip has a unique code programmed into the car's computers to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. However, it is only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. In the absence of that, the car will reject the key and won't start.

It is essential to ensure that you have a spare key for your Saab. This is especially important when you live in a rural area with many car thieves. The good news is that it's possible to obtain a replacement key for your saab ignition key without having to go to a dealership and pay the expensive prices that they demand. In the majority of instances, you can get a brand new key made right on the spot at a fraction of the price of what you'd pay at a dealer.

Key for Wired

Saab cars are usually supplied with two keys. If you own only one, you should get an additional key as soon as you can. This is because if the key is lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This could be expensive especially if you're purchasing a used car.

The next step is to connect the row and columns wires to your microcontroller. This is the most tedious part of the project and it will require a lot of soldering. There's no standard way to go about it, but you must plan how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered together after which it is time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current and prevent them from being shortened. A diode permits current to only flow in one direction. It is equipped with a visible indicator that is black, that indicates which direction current will flow.

Sanabria states that a number of the tools available in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 will assist customers who are shopping or DIY users to program replacement keys and restore immobilizer data. The tools connect to OBD ports and guide the customer through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk for Saab Ignition Key emergency situations, but jumping a battery on modern vehicles may not be the most efficient option. These vehicles are equipped with many digital and computers that communicate with each other. A voltage surge while the battery is connected to another could cause damage to the components and render your car undriveable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of the disabled vehicle. The engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks that could ignite the gasoline that is in the engine compartment.

After the cables have been connected, you need to start the car and let it run for about five minutes. Then, disconnect them in reverse. The battery in the saab replacement keys 9-3 will charge while you drive. It takes a while for it to fall back. It is recommended to purchase a second key fob, as soon as you can. The replacement of the 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 key, it will cost them. The reason for this is that it's not cheap to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It is recommended to have a second key in case of theft or any other catastrophe and the best option is to purchase an extra key as early as you can. Don't purchase a used key, even the case that it's "new." Claimed-new keys from a second-hand store will not work and are almost guaranteed to fail in the most critical moment.

The dealer will charge the highest dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a replacement key without replacing the entire system. This could help you save a significant amount of money. It's also less expensive than waiting until you lose your only key.
