Saab Key Programming
Saab cars manufactured from 1994 have an immobilizer system based on a set of keys. To add an additional key, you need an entirely new transponder and programming. This is usually done at the dealer using a special Tech2 diagnostic tool.
It can be costly. This is the reason why you should always have a spare key available.
Transponder key
The transponder can be described as a key that has an electronic chip. The chip transmits a signal when the key is inserted into the ignition. The car will check to see whether the signal matches the one on the key. If the signals match it will unlock and start. This is a great way to stop auto theft and keep your vehicle safe from thieves.
Transponder keys could be a popular addition to cars, but they are not as safe as traditional metal keys. The metal part of the traditional keys can be easily cut and copied, whereas the transponder is protected by an electronic chip that guards it. The chip has a unique code programmed into the car's computer to identify it.
The car will recognize the Saab keyfob, and allow it to turn on. However, it will only do this if the fob is unmodified and has a chip that has been programmed to match. The car will not start if the key is not programmed to match.
saab ignition key thekeylab.co.uk is important to have a spare Saab key. This is particularly true when you live in a rural area that is home to numerous car thieves. The good part is that you can find a new key for your Saab without having to go to a dealer and pay the expensive prices that they charge. You can have an original key made on the spot at a fraction of the price you'd spend at dealerships.
Wired key
Saab cars are usually delivered with two keys. If you only own one, you should get an additional key as quickly as you can. This is because, if it's lost the car will require a new CIM and the locking cylinders replaced. This can be costly especially if you're buying a second-hand car.
The next step is to wire the row and column wires to the microcontroller. This is the toughest part of the project and it will require a lot of soldering. There is no standard method to accomplish this, but it is important to think about the route you'll take and solder the rows and columns. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are joined, it is time to connect the key switches. To do this, you need to place a diode across each key switch pin and solder it. This will shield the pins that are used for key switches from current and stop them from being shorted. A diode allows current to flow in one direction, and it also has a a black band visual indicator that indicates which way the current will flow.
Sanabria states that some of the tools offered in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508, can help customers who are shopping or DIY users to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the car's computer.
Jump-starting the battery
Most people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery for newer vehicles may not be the best idea. These vehicles are equipped with numerous digital and computers that communicate with one another. A voltage spike when a battery is hooked up to another could cause damage to these components, rendering your car unable to drive.
Connect the cables to the vehicle that is working. Let it run for two minutes. 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 of the black cable to an unpainted, clean metal surface beneath the damaged car's hood. The engine block would be a good choice. Do not connect the black cable to the negative terminal on the dead battery, as this could cause an ignition that ignites the gasoline in the engine bay.
After the cables have been connected, you should begin the car and let it run for approximately five minutes. Then disconnect the cables in reverse. Be aware that the battery of the Saab 9-3 gets recharged while you drive, so it will take a while for the battery to come down. You should consider purchasing an additional key fob as soon as possible. Replacing the original one that works requires the installation and programming of a new computer chip.
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 purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or any other disaster it is advisable to have an extra key. Even even if the key is "new", it will not work.
The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without the need to replace the entire system. That can help you save money. It's cheaper to do this instead of waiting until you lose the only key.
