Saab Key Programming

Saab cars that were built prior to 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required for the addition of an extra key, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

It can be costly. It is always advisable to keep a spare set of keys available.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It transmits a signal to the car when it is inserted into the ignition. The car then checks to see if the signal matches the one on the key. If the signals are the same, the car will unlock itself and begin. This is a great method to deter car theft and keep your vehicle secure from thieves.

Transponder keys are an extremely popular accessory for cars, but they're not as secure as traditional keys made of metal. While the metal parts of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. The chip has an individual code that is embedded into the car's computer to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. However, it will only do this if the key fob is unmodified and has a chip that has been programmed to match the original. The car will not start in the event that the key is not programmed to match.

It's essential to ensure that you have a spare key for your Saab. This is especially important if you reside in a rural area with numerous car thieves. The good part is that you can get a replacement key for your Saab without needing to visit a dealer and pay the high costs that they ask. In the majority of instances, you can get a new key created on-the-spot for less than half the price of what you'd pay at an auto dealer.

Key for Wired

Saab cars typically come with two keys upon purchase. If you only have one, it's an ideal idea to purchase an additional key fob as soon as is possible in case 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 if you're buying a used car.

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. It's not a standard way to do it, but you should determine how To program saab 9-3 key fob to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins that are used for key switches from current and stop them from being shorted. A diode permits current to only flow in one direction. It is equipped with a visible indicator with a black band that shows the direction in which the current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in certain cases create replacement keys and restore lost immobilizer data Sanabria says. The tools plug into the OBD port and automatically guide the customer through the process, making it easier than replacing the computer inside the vehicle.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunk in case of emergency, but jumping a battery for newer vehicles may not be the best idea. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A surge in voltage when a battery is connected to another one could cause damage to the parts and render your vehicle unusable.

Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the non-working one. 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 of the black cable to a clean, unpainted metal surface underneath the 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 cause sparks, which would ignite gasoline in the engine compartment.

Once the cables are connected, you need to start the car and allow it to run for around five minutes. Then disconnect the cables in reverse. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to drop back down. It's a good idea to invest in a spare key fob as soon as you can, since replacing the sole working one requires the installation of a brand new computer module and special programming to convince the system that your lost keys aren't in the process of trying to steal the car.

Replacement case

saab 93 key fob replacement owners usually only have one car key, and if that is lost, they will be charged. It's costly to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It is best to have a spare key in case of theft or any other catastrophe, and the best way is to purchase an additional key as quickly as you can. Don't purchase a used key even it's "new." Keys that are claimed as new from a second-hand store will not perform and are almost certain to fail in the crucial moment.

The dealer will charge you top dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM to make it ready to accept a new key without the need to replace the entire system. This could save you a great deal of money. It's also a lot cheaper than waiting until you lose your only key.
