Saab Key Programming
Saab cars produced from 1994 have an immobilizer system based on keys that are coded. A new transponder is required for addition of an additional key, and special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.
This can be expensive. This is why you should always have a spare key available.
Transponder key
The transponder can be described as a key that is equipped with an electronic chip. The chip transmits a signal when the key is put into the ignition. The car then checks to see whether the signal matches the one on the key. If the signals are identical the car will then unlock itself and start. This is a great method to stop car theft and keep your vehicle secure from thieves.
Transponder keys may be an extremely popular accessory for cars, but they're not as secure as traditional keys made of metal. The metal portion of a traditional key is easily cut and copied, whereas a transponder has an electronic chip which protects it. The chip has a unique code that's programmed into a car's computer order to identify it.
The car will recognize the saab 93 key keyfob and permit it to turn on. However, it can only do this if the fob is unmodified and has a chip that has been programmed to match. If not, the car will reject the key and won't start.
It is vital to have an extra saab ignition key key. This is especially important especially if you reside in a rural location where there are numerous car thieves. You can purchase a new key for your saab ignition key replacement by visiting the dealership and not paying their pricey cost.

Wired key
saab 9 3 key replacement cars usually come with two keys when they're new. If you have only one, it's recommended to purchase an extra key fob as quickly as you can as if you lose it, the car will require the replacement of a CIM unit, and the locking cylinders will have to be replaced. This can be expensive particularly 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 great amount of soldering. There's no standard way to accomplish this, however it is important to think about the routes you'll use to solder the columns and rows. 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 solder it. This will shield the pins from current, and prevent them from getting shorted. A diode lets current only flow in only one direction. It is equipped with a visible indicator with a black band that shows the direction in which the current will flow.
Some of the tools offered at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- could help customers in the shop, or even DIY users in some cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools connect to the OBD port and automatically guide the user through the procedure, making it simpler than replacing the computer inside the vehicle.
Jumpstarting the battery
Most people keep a set of jumper cables in their trunk for emergencies however, jumping a battery in newer automobiles might not be the best choice. These vehicles are equipped with many digital and computer systems that communicate with each other. A voltage spike when the battery is connected to another can fry these components and render your vehicle unable to drive.
Start the working vehicle and let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of the disabled vehicle. The engine block is a great option. The black cable should not be connected to the negative terminal of the dead battery. This could create sparks, which could ignite the gasoline inside the engine compartment.
Once the cables are connected, you can start the vehicle that has been disabled and let it run for approximately five minutes before disconnecting them in reverse order. Be aware that the battery of your Saab 9-3 is charged while you drive, so it could take a while for the battery to go down. It's a good idea buy a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and special programming to convince the system that your lost keys aren't in the process of trying to steal the car.
Replacement case
Many Saab owners have only one key for their car and if they lose that it's going to cost them. The reason is that it's costly to replace a key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's best to have a spare key in the event of theft or any other catastrophe, and the best way is to purchase an additional key as soon as you are able to. Even even if the key is "new" it won't work.
The dealer will charge you top dollars if you only have one working key. However, we can reset and re-program your computer's EEPROM to prepare it to accept an alternative key without replacing the whole system. This could save you a significant amount of money. It's cheaper to do this instead of waiting until you lose the only key.
