saab ignition key replacement (hagan-wiley.technetbloggers.de) Key Programming

Saab cars built since 1994 use an immobilizer system that relies on keys that are coded. The addition of a key requires an entirely new transponder and programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

This can be expensive. Always keep a spare set of keys at hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to the car when it is placed in the ignition. The car then analyzes the signal to determine whether it is the same as the one in the key. If the signals match the car will be able to unlock itself and begin. This is a fantastic way to protect your vehicle from theft.

Transponder keys are an increasingly popular feature in cars, but you should be aware they are not as secure as traditional keys made of metal. While the metal part of a traditional key could be cut and copied but a transponder key is protected by an electronic chip. This chip contains an individual code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob and allow it to turn on. However, it is only able to do so if the key fob has a non-modified chip that has been programmed to match the original. The car won't start if the key is not programmed to match.

It's important to make sure that you have an extra key for your Saab. This is especially true for those who live in a rural area where there are numerous car thieves. The good thing is that you can obtain a replacement key for your Saab without having to go to a dealership and pay the hefty prices that they ask. In the majority of instances, you can get a new key made on-the-spot for less than half the price of what you'd pay at a dealer.

Key for Wired

saab key cars typically come with two keys when they are new. If you have only one, it's a good idea to get an extra key fob as quickly as you can since if you lose it, your car will require the replacement of a CIM unit and the locking cylinders will need to be replaced. This can be costly especially for used vehicles.

The next step is to connect the row and columns wires to your microcontroller. This is the most difficult part of the project, and will require a lot of soldering. There is no standard method to accomplish this, however it is crucial to plan the routes you'll use to solder the columns and rows. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 columns.

After the columns and rows are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins from current, and prevent them from being cut off. A diode allows the current to flow in a single direction, and it also has a a black band visual indicator that shows the direction in which current will flow.

Sanabria says that some of the tools available in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 will assist shoppers 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.

Jumpstarting the battery

Most people keep a few sets of jumper cables in their trunk to use in an emergency however, jumping a battery on newer cars might not be the best choice. These vehicles are equipped with a number of electronic devices and computers that communicate with each other. A voltage surge when the battery is connected another can fry the components making your car inoperable.

Start the vehicle you are using and allow it to run for around two minutes before connecting the cables to the battery that is not working. Attach the red clip to the positive terminal on 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 is an ideal choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite the gasoline in the engine compartment.

Once the cables are connected, start the vehicle and allow it to run for around five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 will be recharged while you drive. It will take a while for it to recharge again. It is recommended to purchase another key fob as soon as possible. The replacement of the one that works requires the installation and programming of a new computer chip.

Replacement Case

Saab owners often only have one car key, and if it is lost, they will be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE in the case of older models. It's best to have a spare key in case of theft or other disaster the best solution is to purchase a second key as soon as you can. Even even if the key is "new" it will not function.

The majority of locksmiths won't be able to help when you only have one working key and the dealer will charge for the cost of replacing the computer in your vehicle to make a new replacement. However, we can reset and re-program your computer's EEPROM to accept a new key without replacing the whole system. This can help you save money. It's also much less expensive than waiting until you lose your one key.
