Saab cars built since 1994 utilize an immobilizer system based on coded keys. A new transponder is required in order to enable the addition of a second key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
The issue is that it can be very expensive. This is why it is important to always have a spare key at hand.
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 check to see whether the signal matches with the one on the key. If the signals are in sync then the car will be able to unlock and start. This is an excellent way to guard your car against theft.
Transponder keys are a popular feature in automobiles, however it is important to know that they are not as secure as classic keys made of metal. The metal part of the traditional key is easily cut and copied, however transponders are protected by an electronic chip that safeguards it. The chip contains a unique code that is programmed into a car's computer order to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if your key fob has an unmodified chip that has been programmed to match it. Otherwise, the car would reject the key and not start.
It's essential to ensure that you have an extra key for your Saab. This is especially true for those who live in a rural area where there are a lot of car burglars. The good part is that you can obtain a replacement key for your Saab without having to go to a dealership and pay the high costs that they demand. In the majority of cases, you can have an original key made on the spot at a fraction of the price of what you would pay at a dealer.
Key for Wired
Saab cars are usually delivered with two keys. If you only own one, you should get an additional key as soon as you can. This is because if the key is lost the car will require a new CIM and the locking cylinders replaced. This could be expensive particularly if you are buying a used car.
The next step is to connect the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a lot of soldering. There is no standardized way to accomplish this, but it is crucial to plan the route you'll take and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has five rows and 17 column.
After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, you need to place a diode across each pin on the key switch and solder it. This will protect the key switch pins from current and prevent them from being shorted. A diode permits current to only flow in only one direction. It has a visual indicator with a black band that shows the direction in which the current will flow.
Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in some cases replace keys in the program and restore lost immobilizer data, Sanabria says. The tools plug into the OBD port and guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.
Jumpstarting the battery
A lot of people keep an item in their trunk to jump start a vehicle in the event of an emergency, however it might not be the best option for vehicles with newer technology. They have numerous digital and electronic devices that communicate with one another. A voltage surge while a battery is hooked up to another one could damage these components, rendering your vehicle unable to drive.
Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the battery that is not working. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the vehicle's hood. An engine block is an excellent choice. Do not connect the black cable to the negative terminal of the dead battery, since this could cause a spark that ignites the gasoline in the engine bay.
Once the cables are connected, turn on the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. The battery in the Saab 9-3 will charge while you drive. It may take a while it to return to its original state. It is recommended to purchase another key fob as soon as possible. Replacing the only one that works requires the installation and programming of a brand new computer chip.
Replacement Case
saab replacement key programming owners typically only have one car key, and if it is lost, they'll be charged. The reason for this is that it's not cheap to add a new key, and it involves 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 advisable to have a spare key. But don't buy a used key even it's "new." Claimed-new keys from sellers selling aftermarket keys won't work and are almost guaranteed to fail in the crucial moment.
Most locksmiths can't help you if you have only one working key, and the dealer will charge you top dollar to replace the computer in your car to create a
replacement saab 9-3 key. We can reset and reprogram the EEEPROM of your computer for it to accept a new key without having to replace the entire system. This could save you lots of money. It's less expensive instead of waiting until you lose the sole key.
