saab spare key Key Programming

Saab cars built since 1994 use an immobilizer system based on keys that are coded. In order to add a second key, it requires a new transponder, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The issue is that this can be quite costly. This is why you should always have a spare key on hand.

Transponder key

The transponder is a key with an electronic chip. This chip sends a signal when the key is inserted in the ignition. The car will check to see if the signal matches the one on the key. If the signals are in sync then the car will be able to unlock and start. This is a great method to deter car theft and keep your car secure from thieves.

Transponder keys are a common feature in automobiles, but it is important to know that they're not as secure as traditional metal keys. The metal component of the traditional key can be easily copied and cut, but the transponder is protected by an electronic chip which protects it. The chip has an unique code that is embedded into the car's computer to identify it.

When a Saab Ignition Key key fob is used the car recognizes it and allows 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 when the key isn't programmed to match.

It is crucial to have a spare Saab key. This is especially true for those who live in a rural area that is home to numerous car thieves. You can get a brand new key for your Saab by going to the dealership without paying their high cost. You can get a replacement saab 9-3 key key created on the spot for less than half the cost you would pay at the dealership.

Wired key

saab 9 3 key replacement cars are usually delivered with two keys. If you only have one, it's an ideal idea to purchase an additional key fob as soon as is possible, because if you lose it the car will require an entirely new CIM unit and the locking cylinders have to be replaced. This could be expensive, especially if you are purchasing a used car.

The next step is to wire the column and row wires to the microcontroller. This is the most laborious aspect of the project and will require a lot of soldering. There isn't a standard way to do this, but it is important to think about the route you'll take and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

After the rows and column are soldered together, it is time to connect the key switches. To do this, place an inverter over each key switch pin and solder it. This will shield the pins on the key switch from current and also prevent them from being shorted. A diode allows current to only flow in only one direction. It is equipped with a visible indicator that is black, that shows which way current will flow.

Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY users in some cases replace keys in the program and restore the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunks in case of emergency, but jumping a battery on newer vehicles might not be the most efficient option. 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 to another could cause damage to the components making your car inoperable.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of the affected car. The engine block is a good alternative. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline that is in the engine compartment.

Once the cables are connected, you need to start the vehicle and let it run about five minutes. Then, disconnect the cables in reverse. The battery in the Saab 9-3 will charge while you drive. It may take a while it to recharge again. It's a good idea invest in a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince it that your missing keys aren't trying to steal the car.

Replacement case

Many Saab owners have only one key for their vehicle and if they lose that it's going to cost them. The reason for this is that it's not inexpensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft, or any other catastrophe it is best to have a spare key. But don't buy a used key, even when it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't perform and are almost certain to fail in the crucial moment.

Most locksmiths cannot help you in the event that you only have one working key and the dealer will charge you high prices to replace the computer in your car to create a replacement. We can reset and reprogram the computer's EEEPROM to get it ready to accept a replacement key without the need to replace the entire system. This could save you a significant amount of money. It's also less expensive than waiting until you lose the only key.
