Saab Key Programming

Saab cars manufactured since 1994 have an immobilizer feature built on coded keys. A new transponder is required in order to enable the inclusion of an additional key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

It can be costly. This is why you should always have a spare key at hand.

Transponder key

The transponder is a key that is equipped with an electronic chip. The chip transmits a signal when the key is placed into the ignition. The car checks to see whether the signal matches with the one on the key. If the signals match it will unlock and start. This is a great method to prevent car theft and keep your vehicle safe from thieves.

Transponder keys are a popular feature in automobiles, but you should be aware they aren't as secure as classic keys made of metal. While the metal parts of a traditional key can be cut and copied, a transponder is protected by an electronic chip. This chip contains an individual code that is encoded into the car's system to identify it.

When a saab ignition key replacement, see this page, key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob if it is equipped with a chip that is unmodified and has been programmed to match. The car won't start if the key is not programmed to match.

It is important to have a spare saab key replacement near me key. This is particularly important especially if you live in a rural region that has many car thieves. The good news is that it's possible to get a replacement key for your Saab without having to go to an auto dealer and pay the expensive prices they ask. You can get a replacement key created on the spot at a fraction of the cost you would spend at the dealership.

Wired key

Saab cars usually come with two keys when they are new. If you only have one, it is an ideal idea to purchase an extra key fob as quickly as you can as 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 costly especially for cars that are used.

The next step is to wire the column and row 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's important to plan out the way you'll route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. This 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. To do this, put a diode across each pin of the key switch and solder it. This will protect the pins from current, thus preventing them from being shortened. A diode only allows the current to flow in a single direction, and it also has a a black band visual indicator that indicates the direction current will flow.

Sanabria states that a number of the tools available in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508, can help customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools connect to the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

A majority of people keep the set in their trunk to jump start a vehicle in an emergency, but it might not be the best idea for cars with more modern technology. These vehicles are equipped with electronic devices and computers that communicate with each other. A surge in voltage when a battery is hooked up to another can fry these components and render your vehicle unable to drive.

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

Once the cables are connected, turn on the vehicle you are not using and let it run for approximately five minutes before you disconnect them in reverse order. Be aware that the battery of the Saab 9-3 gets recharged while you drive, so it can take a while to get the battery back down again. It's a good idea to invest in a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand 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 car and if they lose it, the cost will be. The reason for this is that it's expensive to replace a key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft, or other catastrophe, it is best to have an extra key. Even even if the key is "new" it will not function.

Most locksmiths can't help you with a single working key and the dealer will charge you high prices to replace the computer in your vehicle for a replacement. However, we can reset and re-program the computer's EEPROM in order to prepare it to accept the new key without having to replace the entire system. This could help you save a significant amount of money. It's also less expensive than waiting until you lose your one key.
