Saab Key Programming

Saab cars made since 1994 feature an immobilizer system that relies on key codes. To add an additional key, you need a new transponder, as well as special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

The problem is that it can be very expensive. This is why you should always have a spare key available.

Transponder key

The transponder key is a key with an electronic chip that sends a signal to the car when it is inserted into ignition. The car then examines the signal to determine whether it is identical to that of the key. If the signals are identical the car will be able to unlock itself and start. This is a great method to stop car theft and keep your vehicle secure from thieves.

Transponder keys are a popular addition to cars, but they're not as secure as traditional metal keys. The metal component of the traditional keys can be easily cut and copied, however transponders are protected by an electronic chip that safeguards it. The chip is a unique code that is programmed into a car's computers in order to identify it.

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

It is vital to have a spare Saab key. This is particularly true especially if you live in a rural location that has numerous car thieves. You can get a new key for your Saab by going to the dealership without paying their pricey prices. You can get a replacement key made on the spot for less than half what you would spend at the dealership.

Wired key

Saab cars are usually provided with two keys. If you only have one, it's best to acquire an extra key fob as soon as possible since if you lose it, your car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This could be expensive especially if you're purchasing a used vehicle.

The next step is to connect the column and row wires to the microcontroller. This is the toughest part of the project, and will require lots of soldering. It's not a common way to go about it, but you must think about how to program saab 9-3 key fob to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this you must place a diode on each key switch pin and then solder it. This will shield the pins of the key switch from current and keep them from being shorted. A diode lets current only flow in one direction. It has a visual indicator of a black line that shows which way current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could assist customers at the shop or DIY users in some cases replace keys in the program and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and guide the user through each step and make the process more straightforward than replacing the car'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 in newer vehicles might not be the most efficient option. They have numerous electronic devices and computers that communicate with each other. A surge in voltage while the battery is connected to another can fry these components, rendering your vehicle undriveable.

Start the working vehicle and let it run for about two minutes before you connect the cables to the battery that is not working. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of your disabled vehicle. The engine block is an excellent option. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which could ignite gasoline in the engine compartment.

After the cables have been connected, you should start the car and allow it to run for around five minutes. Then disconnect them in reverse. The battery in your saab 93 key replacement ignition key (find more information) 9-3 will be recharged as you drive. It will take a while for it to drop back down. You should invest in an additional key fob when you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.

Many Saab owners have only one key for their vehicle and if they lose that the cost will be. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE for older models. In the event of theft or any other catastrophe, it is best to have a spare key. Even it's "new", it won't work.

The dealer will charge you the most expensive dollar if you have only one working key. 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 less expensive than wait until you lose the only key.
