Saab Key Programming
Saab cars manufactured since 1994 feature an immobilizer mechanism made up of coded keys. A new transponder is required for the addition of an additional key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
The problem is that it can be very expensive. It is always advisable to keep an extra 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 put into the ignition. The car checks to see whether the signal matches the one on the key. If the signals match the car will then open and start. This is a great method to stop car theft and keep your car safe from thieves.
Transponder keys are a common feature in vehicles, but you should be aware they aren't as secure as classic keys made of metal. While the metal part of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip is a unique code that's programmed into a car's computer in order 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 when it has a chip that is unmodified and has been programmed to match. Otherwise, the car will refuse to accept the key and will not start.
It's crucial to ensure that you have an extra key for your Saab. This is particularly important for those who live in a rural region where there are many car thieves. The good part is that you can get a replacement saab 9-3 key key for your saab 9-3 replacement key without needing to visit a dealer and pay the expensive prices that they ask. In the majority of instances, you can get an original key made on the spot for less than half the cost of what you'd pay at a dealer.
Key for Wired
saab Ignition Key Replacement cars are typically delivered with two keys. If you have only one, it is a good idea to get an additional key fob as quickly as you can in case you lose it, the car will require an entirely new CIM unit and the locking cylinders need to be replaced. This can be expensive especially for used vehicles.
The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There's no standard way to do this, but it is essential to determine the way you'll route and solder the rows and columns. There are 22 microcontroller pins and wires to connect to this keyboard. It has five rows and 17 column.
After the rows and column are soldered together after which it is time to connect the key switches. To do this you must place a diode on each key switch pin and solder it. This will shield the pins from current, thus preventing them from getting shorted. A diode allows current to flow in one direction, and it comes with a the black band as a visual indicator that indicates which way the current will flow.
Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could aid shop customers or DIY customers in certain cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools connect to the OBD port and guide the user through the process, making it more simple than replacing the computer inside the vehicle.
Jumpstarting the battery
A lot of people keep a set of jumper cables in their trunk to use in an emergency, but jumping a battery for newer vehicles might not be the best option. These vehicles are equipped with numerous digital and computers that communicate with each other. A surge in voltage when the battery is connected to another could cause damage to these components and render your vehicle undriveable.
Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood--the engine block is a good choice. Do not connect the black cable to the negative terminal on the dead battery, since this could trigger an ignition that ignites the gasoline in the engine bay.
Once the cables are connected, you should start the car and let it run for about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 will be recharged while you drive. It will take some time for it to fall back. It's a good idea to purchase a spare key fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and special programming to convince it that the lost saab key keys are not trying to steal the car.
Replacement case
Many saab key replacement cost owners only have one key for their car and if they lose that it's going to cost them. The reason for this is that it's not inexpensive to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's recommended to have a spare key in the event of theft or other disaster, and the best way is to purchase an additional key as quickly as you can. Even even if the key is "new" it will not function.
The dealer will charge you top dollars if you only have one working key. However, we can reset and re-program the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This could save you a lot of money. It's also cheaper than waiting until you lose the only key.
