The 12 Best Saab Ignition Key Replacement Accounts To Follow On Twitter
Saab Key Programming
Saab cars manufactured since 1994 feature an immobilizer that relies on a set of keys. A new transponder is required to allow the addition of an extra key, and special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
The issue is that this can be extremely expensive. This is why you should always have a spare key at hand.
Transponder key
The transponder is a piece of key that is equipped with an electronic chip. This chip sends out a signal when the key is put in the ignition. The car then checks to see whether the signal matches the one on the key. If the signals are the same, the car will unlock itself and begin. This is a great way to stop auto theft and keep your car secure from thieves.
Transponder keys are a favored feature in automobiles, but you should be aware that they're not as secure as traditional keys made of metal. The metal component of a traditional key can be easily cut or copied, while a transponder has an electronic chip that protects it. The chip contains a unique code that is programmed into a car's computers in order to identify it.
The car will recognize the Saab keyfob and permit it to turn on. But, it's only able to do this if your key fob is unmodified and has a chip that has been programmed to match the original. The car won't start in the event that the key is not programmed to match.
It is essential to ensure that you have a spare key for your Saab. This is particularly true for those who live in a rural region that has many car thieves. You can get a new key for your Saab by going to the dealership, without having to pay their expensive cost. You can have an original key made on the spot at a fraction of what you would spend at a dealership.
Key for Wired
Saab cars usually come with two keys upon purchase. If you only have one, it is recommended to get an additional key as soon as you can. This 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 are purchasing a used vehicle.
The next step is connecting the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a lot of soldering. It's not a common way to go about it, but you need to think about how to route and connect each column and row. 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 rows and column are joined then it's time to connect the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and also prevent them from being shorted. A diode can only allow current to flow in one direction, and it comes with a an indicator of black color that indicates the direction in which current will flow.
Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in certain instances program replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into the OBD port and guide the user through the procedure, making it simpler than replacing the computer inside the vehicle.
Jump-starting the battery
A majority of people keep an assortment of tools in their trunks to jump-start their car in case of emergency, but this might not be a good idea for newer cars. These vehicles are equipped with numerous digital and computer systems that communicate with each other. A surge of voltage when the battery is connected to another could cause damage to the components making your car inoperable.
Connect the cables to the vehicle that is operating. Let G28CarKeys run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean and unpainted metal surface underneath the hood of the damaged vehicle. The engine block is a good alternative. Do not 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.
After the cables have been connected, you need to start the car and allow it to run for around five minutes. Then, disconnect the cables in reverse. The battery in the Saab 9-3 will charge while you drive. It takes a while for it to drop back down. It's a good idea invest in a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince it that your lost keys aren't in the process of trying to steal the car.
Replacement case
Saab owners often only have one car key, and if that is lost, they will be charged. The reason for this is that it's expensive to replace a 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 other catastrophe, it is best to have an extra key. But don't buy a used key even it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't be effective and are almost guaranteed to fail in the most critical moment.
The majority of locksmiths won't be able to help in the event that you only have one working key and the dealer will charge high prices to replace the computer in your vehicle to make a replacement. However, we can reset and re-program the computer's EEPROM in order to prepare it to accept the new key without having to replace the whole system. This can help you save a significant amount of money. It's also a lot cheaper than waiting until you lose your sole key.
