What Freud Can Teach Us About Saab Ignition Key Replacement

Saab Key Programming

Saab cars built since about 1994 have an immobilizer feature that is based on codes for keys. A new transponder is required in order to enable the addition of a second key, and special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

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

Transponder key

The transponder key is a key with an electronic chip that transmits a signal to the car when it is placed in the ignition. The car then checks the signal to see whether it is identical to the one on the key. If the signals are the same it will open itself and start. This is a great method to guard your car against theft.

Transponder keys are a favored feature in cars, but you must be aware that they aren't as secure as classic metal keys. While the metal part of a conventional key can be cut and copied the transponder is protected by an electronic chip. The chip has a unique code that is inserted into a car's computers in order to identify it.

The car will recognize the Saab keyfob and permit it to turn on. However, it can only do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. If not, the car will reject the key and won't start.

Wired key

saab 93 key cars typically come with two keys upon purchase. If you only have one, it's a good idea to get an additional key fob as quickly as you can as if you lose it, your car will require the replacement saab 9-3 key of a CIM unit, and the locking cylinders have to be replaced.

The next step is to connect the row and column wires to the microcontroller. This is the most challenging part of the project and will require a large deal of soldering. There's no standard way to do this, but it is crucial to plan the route you'll take and solder the columns and rows. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered together, it is time to connect the key switches. To do this, put a diode over each pin of the key switch and then solder it. This will shield the pins from current and prevent them from being shorted. A diode only allows the flow of current to be in one direction, and it comes with a an indicator of black color that indicates which way the current will flow.

Sanabria says that some of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508, can help customers who are shopping or DIY customers to program replacement key for saab 93 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 car's computer.

Jump starting the battery

Most people keep an item in their trunks to start a car in an emergency, but it may not be the best idea for cars with more modern technology.

The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline that is in the engine compartment.

Once the cables are connected, you can start the car and let it run for approximately five minutes. Then, disconnect the cables in reverse. The battery in the saab keys replacement 9-3 will charge while you drive. It will take some time for it to recharge again. You should invest in an additional key fob when you can. Replacing the one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners have only one key for their car and if they lose it, the cost will be. It's expensive to buy a key and requires replacing the CIM or TWICE for older models.
