Saab Ignition Key Replacement Key Programming

saab car key cars manufactured since 1994 use an immobilizer system that is based on a set of keys. The addition of a key requires an entirely new transponder and programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The problem is that it can be very expensive. Always keep a spare set of keys available.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal to car when it is inserted into ignition. The car checks to see whether the signal matches the one on the key. If the signals are the same the car will be able how to open a saab 93 without a key unlock itself and begin. This is a great way to protect your car from theft.

Transponder keys are a common feature in automobiles, but you must be aware that they're not as secure as traditional keys made of metal. The metal portion of a traditional key is easily cut or copied, while the transponder is protected by an electronic chip which protects it. This chip contains 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. But, it's only able to do this if the fob has an unmodified chip that has been programmed to match it. The car will not start when the key isn't programmed to match.

It is essential to have an extra Saab key. This is especially true if you live in a rural region where there are many car thieves. You can get a brand new key for your Saab by visiting the dealership without paying high prices. In most instances, you can get a new key created on-the-spot for less than half the cost of what you would pay at a dealer.

Wired key

Saab cars typically come with two keys when new. If you only have one, it's best to acquire an additional key fob as quickly as you can as if you lose it, your car will require an entirely new CIM unit and the locking cylinders have to be replaced. This could be expensive particularly if you are buying a used car.

The next step is to connect the row and column wires to the microcontroller. This is the most difficult part of the project and will require a good deal of soldering. There isn't a standard way to accomplish this, however it is important to think about the route you'll take and solder the rows and columns. There are 22 microcontroller wires as well as pins to connect for this keyboard. It includes 5 rows and 17 columns.

After the columns and rows are joined It is now time to connect the key switches. To do this, place a diode across each key switch pin and then solder it. This will protect the pins from current, thus preventing them from getting shorted. The diode will only allow the current to flow in a single direction, and it comes with a an indicator of black color that shows the direction in which current will flow.

Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in certain cases create replacement keys and restore lost immobilizer data Sanabria says. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.

Jump-starting the battery

The majority of people have the set in their trunks to jump start a car in case of emergency, but it may not be the best idea for newer cars. These vehicles are equipped with numerous digital and computer systems that communicate with one another. A voltage spike when a battery is hooked up to another can fry these components, rendering your vehicle undriveable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface underneath the hood of the affected car. The engine block is a good alternative. Don't connect the black cable to the negative terminal of the dead battery as it could ignite an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, turn on the vehicle you are not using and let it run for approximately five minutes before disconnecting them in reverse order. Keep in mind that the battery on the Saab 9-3 will be charged when you drive, and it can take a while for the battery to come back down again. You should consider purchasing another key fob as soon as you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Many saab ignition key 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 costly to replace a key, and this 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 recommended to have a spare key. Even even if the key is "new", it will not function.

The dealer will charge you the highest dollar if you only have one working key. We can, however, reset and reprogram the computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This can help you save money. It's less expensive rather than wait until you lose your only key.
