Saab Key Programming

saab 9-3 key fob replacement cars produced since 1994 use an immobilizer that relies on coded keys. A new transponder is required for the addition of a second key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this could be very expensive. It is recommended to always have an extra set of keys in your possession.

Transponder key

The transponder can be described as a key that is equipped with an electronic chip. The chip sends a signal when the key is placed into the ignition. The car then checks to see if the signal matches the one on the key. If the signals match, the car will unlock itself and start. This is a great way to stop auto theft and keep your vehicle safe from thieves.

Transponder keys are a common feature in automobiles, however you must be aware that they are not as secure as traditional metal keys. While the metal component of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code that's programmed into a car's computer order to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob if the device has an unmodified chip and programmed to match. The car will not start when the key isn't programmed to match.

It is important to have a spare Saab Ignition key key. This is particularly true when you live in a rural location that has many car thieves. The good thing is that you can obtain a replacement key for saab 93 key for your Saab without having to go to an auto dealer and pay the high prices that they demand. In most instances, you can get a new key made on-the-spot at a fraction of the cost of what you'd pay at a dealer.

Wired key

saab key fob replacement cars usually come with two keys upon purchase. If you only have one, it is a good idea to get an extra key fob as soon as you can, because if you lose it, the car will require an entirely new CIM unit and the locking cylinders will have to be replaced. This could be expensive especially if buying a second-hand car.

The next step is to wire the wires for the column and row to the microcontroller. This is the most difficult part of the project and will require a good deal of soldering. It's not a common way to do it, but you should plan how to route and connect each column and row. There are 22 microcontroller wires and pins to connect to this keyboard. It has 5 rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to the key switches. Solder a diode to each key switch pin. This will shield the pins from current, and prevent them from getting shorted. The diode will only allow current to flow in one direction, and it has the black band as a visual indicator that indicates which way the current will flow.

Sanabria says that a few of the tools sold in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 will assist customers shopping or DIY customers to program replacement keys and restore immobilizer data. The tools connect to OBD ports and guide the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunk for emergency situations, but jumping a battery for newer vehicles may not be the best idea. These vehicles have many computers and digital devices that communicate with each other. A voltage surge when the battery is connected to another can fry the components making your car inoperable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface beneath the damaged car's hood. 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 create sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, you need to begin the car and let it run for approximately five minutes. Then disconnect the cables in reverse. Remember that the battery on your Saab 9-3 is charged while you drive, so it may take some time for the battery to go down. It's a good idea buy a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a brand new computer module and special programming to convince the system that your lost keys aren't attempting to steal the car.

Replacement case

Many Saab owners have only one key for their car and if they lose it, they'll be charged. The reason for this is that it's not inexpensive to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other catastrophe it is recommended to have an extra key. Don't purchase a used key even it's "new." Keys that are claimed as new from sellers selling aftermarket keys won't work and are almost guaranteed to fail at the crucial moment.

The dealer will charge you top dollar for only one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without the need to replace the entire system. This can save you a great deal of money. It's also much less expensive than waiting until you lose your sole key.
