saab car keys Key Programming
Saab cars that were built prior to 1994 have an immobilizer system made up of coded keys. Adding an extra key requires a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
It can be costly. It is recommended to always have an extra set of keys in your possession.
Transponder key
The transponder is a piece of key that is equipped with an electronic chip. The chip transmits a signal when the key is put into the ignition. The car will then check the signal to determine whether it is the same as the one that is in the key. If the signals are identical the car will then unlock itself and begin. This is a fantastic way to guard your car against theft.
Transponder keys are a common feature in automobiles, but you should be aware that they aren't as secure as classic metal keys. While the metal component of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip is a unique code that is inserted into the car's computer in order to identify it.
The car will recognize the Saab keyfob and permit it to be turned on. The car can only recognize the key fob if it has a chip that is unmodified and programmed to match. The car will not start when the key isn't programmed to match.

saab Car keys by visiting the dealership without paying their expensive prices. You can have a replacement key created on the spot at a fraction of the cost you would spend at a dealership.
Key for Wired
Saab cars are usually supplied with two keys. If you only have one, it's a good idea to get an additional key fob as quickly as you can as if you lose it, the car will require a new CIM unit, and the locking cylinders will need to be replaced. This could be expensive particularly if you are purchasing a used car.
The next step is to wire the wires for the column and row to the microcontroller. This is the most laborious component of the project and will require lots of soldering. There isn't a standard method to go about it, but you need to determine how to route and solder each column and row. There are 22 microcontroller wires and pins that you can connect to this keyboard. It includes 5 rows and 17 columns.
After the columns and rows are joined, it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the key switch pins from current and also prevent them from being shorted. The diode allows current to only flow in one direction. It features a visual indicator with a black band that indicates which direction current will flow.
A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in some cases create replacement keys and restore
lost saab keys immobilizer information, Sanabria says. The tools plug into the OBD port and guide the customer through the process, making it more simple than replacing the computer in the vehicle.
Jump-starting the battery
A majority of people keep a set in their trunk to jump start a vehicle in an emergency, but this might not be a good idea for newer cars. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A voltage spike when a battery is hooked up to another could cause damage to the components and render your car unable to drive.
Start the working vehicle and let it run for about two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged car's hood. The engine block would be an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create a spark, which would ignite gasoline in the engine compartment.
After the cables have been connected, you can start the car and let it run about five minutes. Then, disconnect the cables in reverse. The battery in your
saab 93 replacement key 9-3 is recharged as you drive. It will take some time for it to return to its original state. It's a good idea purchase a spare key fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and a special program to convince it that your missing 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 it, it's going to cost them. The reason for this is that it's not cheap to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's recommended to have a spare key in case of theft or other disaster and the best option is to purchase an extra key as quickly as you can. Even when the key is "new", it will not work.
Most locksmiths can't help you with a single working key and the dealer will charge you top dollar to replace the computer in your car to create a replacement. However, we can reset and reprogram the computer's EEPROM in order to prepare it to accept a new key without replacing the entire system. This could save you a significant amount of money. It's cheaper to do this than waiting until you loose the only key.
