Saab Key Programming

Saab cars made since 1994 feature an immobilizer system that relies on a set of keys. The addition of a key requires a new transponder and 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 can be described as a key equipped with an electronic chip. This chip sends out a signal when the key is inserted in the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals match it will unlock and start. This is a fantastic way to guard your car against theft.

Transponder keys may be a popular addition to cars, but they are not as safe as traditional keys made of metal. The metal part of the traditional key can easily be cut or copied, while transponders are protected by an electronic chip that protects it. This chip contains an unique code that's programmed into a car's computers in order to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. The car will only recognize the key fob when it has an unmodified chip and has been programmed to match. The car will not start in the event that the key is not programmed to match.

It's important to make sure that you have an extra key for your Saab. This is particularly important for those who live in a rural location where there are a lot of car burglars. You can get a brand new key for your saab ignition key replacement by going to the dealership, without having to pay their pricey cost. In most instances, you can get an original key made on the spot at a fraction of the cost you'd pay at the dealer.

Key for Wired

Saab cars are typically delivered with two keys. If you only have one, it is an ideal idea to purchase an extra key fob as soon as possible since if you lose it, the car will require the replacement of a CIM unit, and the locking cylinders will have to be replaced. This can be costly especially if buying a second-hand car.

The next step is to connect the row and columns wires to your microcontroller. This is the most difficult component of the project and it will require lots of soldering. There is no standardized way to accomplish this, but it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's the time to connect them to key switches. To do this, you need to place a diode on each pin of the key switch and then solder it. This will protect the key switch pins from current and keep them from being shorted. A diode lets current only flow in only one direction. It comes with a visual indicator, a black band, that indicates which direction current will flow.

Sanabria says that some of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 can assist customers shopping or DIY customers to program replacement keys and restore immobilizer information. The tools connect to OBD ports and guide the customer through each step, making the process easier than replacing the vehicle's computer.

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 cars are equipped with a variety of digital and computer systems that communicate with one another. A voltage surge when the battery is connected another battery could damage the components and render your vehicle 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 good battery (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 choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, you can start the vehicle and let it run for approximately five minutes. Then, disconnect them in reverse. Keep in mind that the battery on your saab replacement key 9-3 is charged when you drive, so it may take some time for the battery to go back to normal. It's a good idea to invest in a spare key fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and special programming to convince it that the lost keys are not trying to steal the car.

Replacement case

Saab owners usually only have one car key, and if that is lost, they will be charged. The reason is that it's costly to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft or any other disaster it is best to have a spare key. Even it's "new", it won't work.

The majority of locksmiths won't be able to help with a single working key, and the dealer will charge you for the cost of replacing the computer in your vehicle to make a replacement. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept a new key without replacing the entire system. This can save you lots of money. It's also much less expensive than waiting until you lose your only key.
