20 Resources To Make You Better At Saab Ignition Key Replacement
Saab Key Programming
Saab cars that were built prior to 1994 come with an immobilizer system made up of coded keys. A new transponder is required to allow the addition of an additional key, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.
The issue is that this could be very expensive. It is recommended to always have a spare set of keys on hand.
Transponder key
The transponder key comes equipped with an electronic chip. It sends a signal to the car when it is put into the ignition. The car will check to see whether the signal matches the one on the key. If the signals are in sync the car will then unlock and begin. This is a great way to protect your vehicle from theft.
Transponder keys are an increasingly popular feature for automobiles, but they are not as safe as traditional keys made of metal. While the metal portion of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. The chip has a unique code that is programmed into a car's computers in order to identify it.
The car will recognize the Saab keyfob, and allow it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and has been programmed to match. The car will not start in the event that the key has not been programmed to match.
It is essential to ensure that you have a spare key for your Saab. This is particularly important when you live in a rural area where there are a lot of car thieves. The good news is that you can find a replacement key to your Saab without needing to visit an auto dealership and pay the high prices that they ask. In the majority of instances, you can get a new key made on-the-spot at a fraction of the cost you'd pay at the dealer.
Key for Wired
Saab cars usually come with two keys when new. If you have only one, you need to purchase an additional key as fast as you can. This is because, if it's lost and the car needs a new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.
The next step is to wire the wires of the column and row to the microcontroller. This is the most tedious 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 how you will route and solder the columns and rows. There are 22 microcontroller pins and wires to connect for this keyboard. It has five rows and 17 column.
After the columns and rows are soldered together It is now time to connect the key switches. Solder saab car key on each key switch pin. This will shield the pins from current, thus preventing them from being shorted. A diode allows current to flow in one direction, and has a an indicator in black that indicates the direction in which current will flow.
Sanabria states that some of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer data. The tools plug into OBD ports and help the customer through each step, making the process easier than replacing the vehicle's computer.
Jump starting the battery
A lot of people keep a set of jumper cables in their trunks for emergencies however, jumping a battery on newer vehicles may not be the best idea. These vehicles are equipped with many digital and computers that communicate with one another. A voltage surge while a battery is hooked up to another battery could fry these components and leave your vehicle undriveable.
Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of the affected vehicle. The engine block is a great option. Don't connect the black cable to the negative terminal of the dead battery, as it could ignite a spark that ignites the gasoline in the engine bay.
Once the cables are connected, turn on the vehicle that has been disabled and let it run for approximately five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 will recharge while you drive. It will take a while for it to return to its original state. It is a good idea to buy a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a new computer module and special programming to convince it that the lost keys aren't attempting 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 buy keys and will require replacing the CIM or TWICE in the case of older models. It is best to have a second key in the event of theft or other disaster and the best option is to buy an extra key as early as you can. Even even if the key is "new", it will not function.
Most locksmiths can't help you in the event that you only have one 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 computer's EEEPROM to make it ready to accept a new 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 your only key.
