Saab Key Programming
Saab cars built from 1994 have an immobilizer system that relies on keys that are coded. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
It can be costly. It is always advisable to keep a spare set of keys in your possession.
Transponder key
The transponder is a piece of key with an electronic chip. This chip sends a signal when the key is placed into the ignition. The car then examines the signal to determine whether it matches the one that is in the key. If the signals are identical the car will be able to unlock itself and begin. This is a great method to stop car theft and keep your vehicle safe from thieves.
Transponder keys could be an extremely popular accessory for cars, but they are not as safe as traditional metal keys. The metal part of the traditional key can easily be cut or copied, while transponders have an electronic chip which protects it. This chip contains 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. The car will only recognize the key fob if the device has an unmodified chip and 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 especially important especially if you live in a rural location that has many car thieves. You can obtain a replacement key for your Saab by going to the dealership, without having to pay their pricey cost. You can get an original key made on the spot for less than half of what you would pay at a dealership.
Key for Wired
Saab cars are usually supplied with two keys. If you have only one, it is recommended to get an additional key as fast as you can. saab 93 key programming is because, if it's lost and the car needs an entirely new CIM and the locking cylinders replaced. This could be expensive especially if you're purchasing a used car.
The next step is to wire the column and row wires to the microcontroller. This is the most difficult part of the project and requires a significant amount of soldering. There is no standard method 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 five rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.
After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins from current, preventing them from being shortened. A diode permits current to only flow in only one direction. It features a visual indicator of a black line that shows the direction in which the current will flow.
Sanabria says that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 will assist shoppers or DIY customers to program replacement keys and restore immobilizer data. The tools connect to OBD ports and guide the customer through each step which makes the process much easier than replacing the vehicle's computer.
Jumpstarting the battery
A lot of people keep an assortment of tools in their trunk to jump-start their car in an emergency, however it might not be a good idea for cars with more modern technology. These vehicles are equipped with many digital and computer systems that communicate with one another. A surge in voltage when the battery is connected to another can fry the components and render your car unable to drive.
Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the car's hood. The engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery because it could ignite an ignition that ignites the gasoline in the engine bay.
After the cables have been connected, you can start the car and allow it to run for around five minutes. Then, disconnect the cables in reverse. Be aware that the battery of your Saab 9-3 is charged while you drive, so it will take a while for the battery to go down. It's 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 special programming to convince it that your missing keys aren't in the process of trying to steal the car.
Replacement case
Saab owners typically only have one car key, and if it is lost, they will be charged. The reason for this is that it's not cheap to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is best to have a second key in the event of theft or any other catastrophe and the most effective way is to purchase an additional key as early as you can. But don't buy a used key, even when it's "new." Keys that are claimed as new from sellers selling aftermarket keys won't work and are almost guaranteed to fail in the most critical moment.
Most locksmiths can't help you with a single working key and the dealer will charge you top dollar to replace the computer in your vehicle to make a replacement. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a new key without the need to replace the entire system. This can save you a lot of money. It's much cheaper rather than wait until you lose the only key.
