saab keys replacement cars manufactured since 1994 feature an immobilizer that relies on a set of keys. A new transponder is required to allow the addition of an extra key, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.
The problem is that this can be very expensive. It is recommended to always have a spare set of keys available.
Transponder key
The transponder is a piece of key with an electronic chip. The chip sends a signal when the key is inserted into the ignition. The car is able to check whether the signal matches with the one on the key. If the signals match then the car will be able to unlock and start. This is a great method to stop car theft and keep your car secure from thieves.
Transponder keys are a favored feature in vehicles, but you should be aware they're not as secure as traditional metal keys. The metal part of the traditional keys can be easily cut and copied, whereas transponders have an electronic chip which protects it. The chip has a unique code that is programmed into the car's computer to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if it has an unmodified chip and programmed to match. The car won't start in the event that the key is not programmed to match.
It's crucial to ensure that you have a spare key for your Saab. This is especially true especially if you reside in a rural area, where there are a lot of car burglars. You can obtain a replacement key for your Saab by visiting the dealership without paying high costs. You can have an original key made on the spot for less than half the price you'd pay at a dealership.
Wired key
saab car keys cars typically come with two keys when they are new. If you have only one, it is best to acquire an additional key fob as quickly as you can as if you lose it the car will require an entirely new CIM unit, and the locking cylinders will have to be replaced. This can be costly 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 challenging part of the project and will require a large amount of soldering. There's no standard way to accomplish this, however it is important to think about the way you'll route and solder the rows and columns. There are 22 microcontroller wires and pins to connect for this keyboard. It has five rows and 17 column.
Once the rows and columns are soldered, it's time to connect them to the key switches. To do this you must place a diode across each key switch pin and solder it. This will shield the pins from current, and prevent them from being shortened. A diode only allows the current to flow in a single direction, and it has an indicator of black color that indicates the direction in which current will flow.
Some of the tools available 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 data Sanabria says. The tools plug into OBD ports and guide the customer through each step which makes the process much easier than replacing the car's computer.
Jump starting the battery
The majority of people have a set of jumper cables in their trunk for emergency situations, but jumping a battery on newer cars might not be the most efficient option. These vehicles are equipped with computers and digital devices which communicate with each other. A surge in voltage when the battery is connected to another one could damage the components and render your car undriveable.
Start the working vehicle and allow it to run for around 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 have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface underneath the hood of the disabled vehicle. The engine block is a great option. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks that could ignite gasoline in the engine compartment.
After the cables have been connected, you can start the vehicle and allow it to run for around five minutes. Then disconnect the cables in reverse. Be aware that the battery in the Saab 9-3 gets recharged while you drive, so it can take a while to get the battery down. It's a good idea invest in a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and special programming to convince it that your Lost Saab Key keys aren't attempting to steal the car.
Replacement Case
Many Saab owners have only one key for their car and if they lose that they'll be charged. It's expensive to add an additional key and it requires replacing the CIM or TWICE in the case of older models. In the event of theft, or other catastrophe, it is best to have a spare key. But don't buy a used key, even when it's "new." Keys that are claimed as new purchased from third-party sellers won't work and are likely to fail at the crucial moment.
The dealer will charge you the highest dollar if you have only one working key. We can, however, reset and reprogram the computer's EEPROM to accept the new key, without replacing the entire system. This can save you a lot of money. It's cheaper to do this than waiting until you loose the only key.
