Saab Key Programming
Saab cars built from 1994 have an immobilizer system based on key codes. Adding an extra key requires an entirely new transponder and programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
This can be expensive. It is always advisable to keep a spare set of keys available.
Transponder key
The transponder key is a key equipped with an electronic chip. It transmits a signal to the car when it is inserted into the ignition. The car then analyzes the signal to determine whether it matches the one that is in the key. If the signals are in sync, the car will open and start. This is a great method to prevent car theft and keep your car secure from thieves.
Transponder keys can be an extremely popular accessory for automobiles, but they are not as safe as traditional metal keys. The metal part of the traditional key can easily be cut and copied, whereas the transponder is protected by an electronic chip that protects it. This chip has a 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 will only do so if the key fob has an unmodified chip that has been programmed to match. The car will not start in the event that the key is not programmed to match.
It is vital to have a spare Saab key. This is particularly true if you reside in a rural area that is home to many car thieves. You can get a brand new key for your Saab by going to the dealership without paying their high cost. In most cases, you can have a brand new key made right on the spot at a fraction of the price of what you would pay at dealerships.
Key for Wired
saab spare key cars are usually delivered with two keys. If you have only one, it's recommended to purchase an additional key fob as soon as possible, because if you lose it, the car will require an entirely new CIM unit, and the locking cylinders will need to be replaced. This can be expensive especially for cars that are used.
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 is no standard method to accomplish this, however it is essential to determine the way you'll route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered, it's time to connect them to key switches. To do this, you need to place a diode over each pin on the key switch and solder it. This will shield the pins from current, preventing them from getting shorted. A diode can only allow current to flow in one direction, and has a a black band visual indicator that indicates which way the current will flow.
Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or DIY customers in certain cases replace keys in the program and restore lost immobilizer data, Sanabria says. The tools connect to OBD ports and guide the user through each step making the process simpler than replacing the vehicle's computer.
Jump starting the battery
Most people keep a set in their trunks to jump-start their vehicle in the event of an emergency, but it might not be a good idea for vehicles that are newer. These vehicles have many digital and electronic devices that communicate with one another. A voltage surge when the battery is connected another could cause damage to the components making your car inoperable.
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's good. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood--the engine block is a good option. Do not connect the black cable to the negative terminal on the dead battery as it could ignite an ignition source that ignites gasoline in the engine bay.
After the cables have been connected, you should start the vehicle and allow it to run for around five minutes. Then disconnect them in reverse. Keep in mind that the battery on your saab fob key replacement 9-3 is recharged during your drive, which means it will take a while for the battery to go down. It is a good idea to invest in 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 lost saab keys keys aren't attempting to steal the car.
Replacement case
saab key fob replacement owners usually have only one car key, and if that is lost Saab Keys, they'll be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE for older models. It's recommended to have a backup key in the event of theft or other disaster the best solution is to buy an extra key as quickly as you can. Even if the key is "new" it won't work.
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 a new key without replacing the whole system. That can save you lots of money. It's also cheaper than waiting until you lose your sole key.
