Saab Key Programming
Saab cars that were built prior to 1994 come with an immobilizer system based on coded keys. To add an additional key, you need an entirely new transponder and programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
It can be costly. This is the reason why you should always have a spare key at hand.
Transponder key
The transponder is a piece of key that has an electronic chip. This chip sends a signal when the key is placed in the ignition. The car checks to see whether the signal matches the one on the key. If the signals match it will open itself and begin. This is a great way to stop car theft and keep your vehicle safe from thieves.
Transponder keys are a common feature in cars, but you should be aware that they aren't as secure as classic metal keys. While the metal portion of a conventional key can be cut and copied, a transponder is protected by an electronic chip. The chip has a unique code that is encoded into the car's system to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it is only able to do so if the key fob has a non-modified chip that has been programmed to match it. Otherwise, the car will refuse to accept the key and will not start.
It's essential to ensure that you have an extra key for your Saab. This is particularly important if you live in a rural region where there are a lot of car thieves. You can get a brand new key for your saab replacement keys by going to the dealership and not paying their high prices. You can get the replacement key on the spot for less than half the price you'd spend at an auto dealer.
Key for Wired
Saab cars usually come with two keys upon purchase. If you only have one, you should get an additional key as soon as you can. This is because if you lose it 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 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 determine how to connect and solder each column and row. For this keyboard, there are five 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 the time to connect them to the key switches. To do this, place a diode on each key switch pin and then solder it. This will shield the pins from current, and prevent them from being cut off. The diode will only allow current to flow in one direction, and it comes with a an indicator in black that indicates the direction current will flow.
A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- may aid shop customers or DIY users in some cases replace keys in the program and restore lost immobilizer data, Sanabria says. The tools plug into the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.
Jump starting the battery
Most people keep a set of jumper cables in their trunks in case of emergency, but jumping a battery on modern automobiles might not be the best option. These cars have a variety of electronic devices and computers that communicate with one another. A voltage surge when a battery is connected to another can fry the components and render your vehicle unusable.
Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean unpainted metal surface underneath the hood of the disabled vehicle. The engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline in the engine compartment.
Once the cables are connected, start the disabled vehicle and let it run for approximately five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 will recharge as you drive. It will take some time for it to recharge again. It is recommended to purchase an additional key fob as soon as you can. Replacing the one that works requires the installation and programming of a brand new computer chip.
Replacement case
Saab owners usually only have one car key, and if that is lost, they will be charged. It's expensive to buy a key and requires replacing the CIM or TWICE for older models. It's best to have a backup key in case of theft or any other catastrophe and the best option is to purchase a second key as soon as you can. Even when the key is "new" it won't work.
The dealer will charge you the most expensive dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a new key without replacing the entire system. That can save you a significant amount of money. It's also less expensive than waiting until you lose the only key.
