Saab Key Programming
Saab Ignition Key cars that were built prior to 1994 come with an immobilizer system built on coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done at the dealer using a Tech2 diagnostic tool.
It can be costly. This is the reason why you should always have a spare key available.
Transponder key
The transponder keys are keys equipped with an electronic chip. It sends a signal to the car when it is put into the ignition. The car then examines the signal to see whether it is identical to the one on the key. If the signals are in sync, the car will unlock and begin. This is a fantastic way to protect your car from theft.
Transponder keys may be an increasingly popular feature for cars, but they are not as secure as traditional metal keys. While the metal portion of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. This chip contains an unique code that is inserted into the car's computer in order to identify it.
The car will recognize the saab key fob repair keyfob, and allow it to be turned on. The car will only recognize the key fob if it has a chip that is unmodified and programmed to match. If not, the car will reject the key and not start.
It is vital to have an extra saab replacement keys key. This is particularly true when you live in a rural area that is home to numerous car thieves. The good thing is that you can find a new key for your Saab without needing to visit a dealer and pay the hefty prices that they charge.

Key for Wired
saab key code cars are usually provided with two keys. If you only have one, it's recommended to purchase an extra key fob as soon as is possible as if you lose it the car will require the replacement of a CIM unit, and the locking cylinders need to be replaced. This can be costly particularly for used cars.
The next step is to wire the wires of the column and row to the microcontroller. This is the toughest component of the project and it will require lots of soldering. There is no standard method to do this, but it's important to plan out how you will route and solder the columns and rows. For this keyboard, there are five 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 together, it is time to connect the key switches. To do this, put an inverter over each key switch pin and solder it. This will shield the pins that are used for key switches from current and prevent them from being shorted. A diode lets current only flow in only one direction. It comes with a visual indicator, a black band, that shows which way current will flow.
Sanabria says that some of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 will assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and automatically guide the customer through the procedure, making it much easier than replacing the computer inside the vehicle.
Jump-starting the battery
A majority of people keep an item in their trunk to jump start a car in an emergency, but this might not be the best option for vehicles with newer technology. They have numerous electronic devices and computers that communicate with one another. A voltage surge while a battery is hooked up to another could cause damage to these components and render your car 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 of the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface beneath the hood of the disabled car. The engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery as it could ignite an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, turn on the vehicle that has been disabled and let it run for about five minutes before disconnecting the cables in reverse order. Remember that the battery on the Saab 9-3 will be charged while you drive, so it may take some time for the battery to go down. You should purchase a second key fob, when you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.
Replacement Case
saab replacement key programming owners usually have only one car key, and if that is lost, they will be charged. The reason for this is that it's costly to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's best to have a backup key in the event of theft or other disaster and the most effective way is to purchase an extra key as soon as you are able to. However, don't purchase a secondhand key, even when it's "new." Claimed-new keys from sellers selling aftermarket keys won't be effective and are almost guaranteed to fail at the critical moment.
The dealer will charge the highest dollar for only one working key. However, we can reset and reprogram the computer's EEPROM in order to prepare it to accept the new key without having to replace the entire system. This can save you lots of money. It's also much less expensive than waiting until you lose the only key.
