Saab Key Programming

Saab cars manufactured since 1994 utilize an immobilizer system that is based on key codes. A new transponder is required for the addition of an extra key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

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

Transponder key

The transponder is a type of key equipped with an electronic chip. This chip sends a signal when the key is inserted into the ignition. The car then analyzes the signal to determine whether it matches the one on the key. If the signals are identical the car will be able to unlock itself and start. This is a great way to protect your vehicle from theft.

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

When a saab Car keys key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob if the device has 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 vital to have an extra Saab key. This is especially true when you live in a rural location where there are numerous car thieves. You can purchase a new key for your Saab by going to the dealership and not paying their pricey prices. In most instances, you can get a new key made on-the-spot at a fraction of the cost you would pay at an auto dealer.

Wired key

Saab cars typically come with two keys when they are new. If you have only one, you should get an extra key as soon as you can. This is because, if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially for used cars.

The next step is to connect the wires for columns and row to your microcontroller. This is the most tedious component of the project and it will require a lot of soldering. It's not a standard way to do it, but you must plan how to route and solder each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has 5 rows and 17 column.

Once the rows and columns are soldered, it's the time to connect them to key switches. To do this, place a diode across each pin on the key switch and then solder it. This will shield the pins from current and prevent them from getting shorted. A diode permits current to only flow in only one direction. It comes with a visual indicator that is black, that indicates which direction current will flow.

Sanabria says that a few of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 can assist shoppers or DIY users to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the car's computer.

Jumpstarting the battery

A lot of people keep a set of jumper cables in their trunk for emergencies however, jumping a battery in newer vehicles may not be the most efficient option. These cars have a variety of electronic devices and Saab Car keys computers that communicate with each other. A surge in voltage when the battery is connected to another could cause damage to the components, rendering your car undriveable.

Connect the cables to the vehicle that is working. Let it 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 a clean, unpainted metal surface underneath the disabled vehicle's hood. An engine block is an ideal choice. Don't connect the black cable to the negative terminal of the dead battery as it could spark an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle and let it run for approximately five minutes. Then disconnect them in reverse. Be aware that the battery of the Saab 9-3 will be charged when you drive, so it will take a while to get the battery down. It's a good idea purchase a spare 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 it that your lost keys aren't trying to steal the car.

Replacement Case

Many saab key fob programming owners have only one key for their car and if they lose that it's going to cost them. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other calamity it is best to have an extra key. However, don't purchase a secondhand key, even when it's "new." Keys that are claimed as new from sellers selling aftermarket keys won't work and are likely to fail in the crucial moment.

The dealer will charge you the highest dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a new key without having to replace the entire system. This could save you a lot of money. It's also much less expensive than waiting until you lose your sole key.
