Saab Key Programming

Saab cars made since 1994 have an immobilizer system that is based on codes for keys. A new transponder is required to allow the addition of an additional key, and special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

The problem is that it can be very costly. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder is a key equipped with an electronic chip. The chip sends a signal when the key is placed into the ignition. The car then analyzes the signal to see if it matches that of the key. If the signals match, the car will open and start. This is a great way to protect your car from theft.

Transponder keys are a popular feature in cars, but you must be aware that they aren't as secure 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. The chip is equipped with an individual code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. But, it's only able to do so 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 has not been programmed to match.

It is crucial to have an extra Saab key. This is especially true especially if you live in a rural region that has numerous car thieves. You can obtain a replacement key for your Saab by visiting the dealership without paying their pricey cost. You can have the replacement key on the spot for less than half the price you'd pay at a dealership.

Key for Wired

Saab cars are typically delivered with two keys. If you have only one, you should get an additional key as quickly as you can. This is because if you lose it, the car will need a new CIM and the locking cylinders replaced. This can be costly especially if buying a second-hand car.

The next step is to connect the column and row wires to the microcontroller. This is the most laborious part of the project, and will require a lot of soldering. It's not a common way to go about it, however, you should consider how to get a saab replacement key you will route and saab key programming solder each column and row. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 column.

After the columns and rows are joined then it's time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins on the key switch from current and prevent them from being shorted. A diode can only allow the flow of current to be in one direction, and it comes with a an indicator of black color that indicates the direction current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY customers in some cases replace keys in the program and restore lost saab keys immobilizer information, Sanabria says. The tools plug into the OBD port and automatically guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk for emergencies, but jumping a battery for newer vehicles may not be the best option. These cars are equipped with a variety of electronic devices and computers that communicate with each other. A surge in voltage when a battery is connected to another could cause damage to the components making your car unusable.

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 of the black cable to an unpainted, clean metal surface underneath the car's hood. The engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could create sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, you need to start the car and let it run for approximately five minutes. Then disconnect them in reverse. Be aware that the battery of your Saab 9-3 is recharged when you drive, and it will take a while for the battery to go back down again. You should purchase a second key fob, as soon as you can. Replacing the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Saab owners usually only have one car key, and if that is lost, they will be charged. It's costly to add the key and also requires replacing the CIM or TWICE in the case of older models. In the event of theft or other catastrophe, it is best to have an extra key. Even even if the key is "new", it won't work.

The dealer will charge you the most expensive dollar for Saab Key Programming only one working key. We can, however, reset and reprogram the computer's EEPROM to accept a new key without replacing the entire system. This can save you a significant amount of money. It's also a lot cheaper than waiting until you lose your only key.
