Saab Key Programming

Saab cars manufactured since 1994 have an immobilizer feature based on coded keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The issue is that it can be extremely expensive. You should always keep an extra set of keys at hand.

Transponder key

The transponder is a type of key that has an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car checks to see whether the signal is the same as the one on the key. If the signals are the same the car will be able to unlock itself and begin. This is a fantastic way to protect your vehicle from theft.

Transponder keys are an increasingly popular feature in automobiles, however you should be aware they aren't as secure as classic metal keys. While the metal part of a traditional key could be cut and copied the transponder is protected by an electronic chip. This chip has a unique code programmed into the car's computers to identify it.

When a Saab 9-3 Key Not Accepted Contact Service (Cameradb.Review) 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 a chip that is unmodified and has been programmed to match. Otherwise, the car will reject the key and won't start.

It's important to make sure that you have an extra key for your Saab. This is particularly true if you reside in a rural area that is home to numerous car thieves. You can purchase a new key for your Saab by going to the dealership, without having to pay their pricey cost. In the majority of instances, you can get a new key made on-the-spot at a fraction of the cost you would pay at a dealer.

Wired key

Saab cars typically come with two keys when they are new. If you only have one, it is an ideal idea to purchase an extra key fob as soon as possible as if you lose it, your car will require the replacement of a CIM unit, and the locking cylinders have to be replaced. This can be costly especially for cars that are used.

The next step is to wire the row and column wires to the microcontroller. This is the most laborious part of the project and it will require lots of soldering. There's no standard way to go about it, but you should think about how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins that you need 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 across each pin on the key switch and solder it. This will shield the pins from current, preventing them from being shorted. The diode allows current to only flow in one direction. It has a visual indicator of a black line that indicates which direction current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunks to use in an emergency, but jumping a battery in newer cars might not be the most efficient option. These vehicles have many digital and electronic devices that communicate with one another. A surge in voltage while a battery is hooked up to another one could damage the components and render your vehicle unable to drive.

Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal on 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 would be an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite the gasoline that is in the engine compartment.

After the cables have been connected, begin the car and let it run for about five minutes. Then disconnect them in reverse. Be aware that the battery of your Saab 9-3 is charged when you drive, so it could take a while for the battery to go back to normal. It's a good idea buy a spare key fob as soon as you can, because replacing the one that works requires the installation of a new computer module and a special program to convince it that the lost saab key keys aren't attempting to steal the car.

Replacement case

Many Saab owners have only one key for their vehicle and if they lose it, key, it will cost them. 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, as well as programming. In the event of theft or any other calamity, it is best to have an extra key. Don't buy a secondhand key, even the case that it's "new." Claimed-new keys from sellers selling aftermarket keys won't work and are likely to fail at the crucial moment.

The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer to be able to accept a replacement key without replacing the entire system. This could save you a great deal of money. It's also a lot cheaper than waiting until you lose your sole key.
