Saab Key Programming
Saab cars built since 1994 feature an immobilizer system that relies on a set of keys. In order to add a second key, it requires a new transponder and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The issue is that this can be very costly. It is always advisable to keep a spare set of keys in your possession.
Transponder key
The transponder keys are keys with an electronic chip that sends a signal to car when it is inserted into ignition. The car checks to see if the signal matches the one on the key. If the signals match the car will then unlock and begin. This is a great way to safeguard your car from theft.
Transponder keys may be an extremely popular accessory for cars, but they are not as safe as traditional keys made of metal. While the metal portion of a traditional key may be cut and copied the transponder is protected by an electronic chip. This chip has an unique code that is embedded 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. However, it is only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. Otherwise, the car would refuse to accept the key and will not start.
It is vital to have an extra Saab key. This is particularly important if you reside in a rural area that is home to many car thieves. You can get a new key for your Saab by visiting the dealership without paying expensive costs. You can have the replacement key on the spot for less than half of the price you'd spend at an auto dealer.
Key for Wired
Saab cars usually come with two keys when they're new. If you only own one, you should get an additional key as quickly as you can. This is because if the key is lost and the car needs a new CIM and the locking cylinders replaced. This could be expensive especially if buying a used car.
The next step is to connect the row and column wires to the microcontroller. This is the most difficult component of the project and will require lots of soldering. There isn't a standard way to accomplish this, however it is crucial to plan the route you'll take and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered together, it is time to connect the key switches. To do this, you need to place a diode across each key switch pin and then solder it. This will shield the pins from current, thus preventing them from being shorted. A diode only allows the current to flow in a single direction, and it has an indicator in black that indicates which way the current will flow.
Sanabria says that a few of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508, can help customers who are shopping or DIY customers to program replacement keys and restore immobilizer data. The tools connect to OBD ports and help the customer through each step and make the process more straightforward than replacing the vehicle's computer.
Jumpstarting the battery
A lot of people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery on modern automobiles might not be the most efficient option. These vehicles have many electronic devices and computers that communicate with each other. A voltage surge when the battery is connected to another battery could damage the components making your car unusable.
Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach saab key replacement cost The Key Lab of the black cable to an unpainted, clean metal surface beneath the damaged vehicle's hood. An engine block is an ideal choice. Don't connect the black cable to the negative terminal of the dead battery, since it could spark an ignition that ignites the gasoline in the engine bay.
Once the cables are connected, start the disabled vehicle and let it run for approximately five minutes before disconnecting the cables in reverse order. Be aware that the battery in the Saab 9-3 gets recharged when you drive, so it could take a while for the battery to go back down again. It's a good idea to purchase a spare fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that your lost keys aren't trying to steal the car.
Replacement case
Many Saab owners have only one key for their car and if they lose it, they'll be charged. It's expensive to purchase keys and will require replacing the CIM or TWICE for older models. In the event of theft, or any other disaster it is recommended to have a spare key. Even when the key is "new", it won't work.
The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a replacement key without having to replace the entire system. This can save you lots of money. It's cheaper to do this rather than wait until you lose the only key.
