Saab Key Programming

Saab 9 3 Key Replacement cars made since 1994 have an immobilizer system based on coded keys. A new transponder is required in order to enable the inclusion of an additional key, and special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

The issue is that it can be very costly. Always keep an extra set of keys available.

Transponder key

The transponder key is a key with an electronic chip that sends a signal to the car when it is inserted into the ignition. The car will then check the signal to determine whether it matches the one on the key. If the signals match, the car will unlock and begin. This is a great way to stop car theft and keep your car safe from thieves.

Transponder keys are a common feature in vehicles, but you should be aware that they're not as secure as classic metal keys. The metal portion of a traditional key can be easily cut and copied, however the transponder is protected by an electronic chip which protects it. The chip has a unique code that is inserted into a car's computer in order to identify it.

The car will recognize the saab ignition key replacement keyfob and allow it to be turned on. However, it is only able to do this if your key fob has a non-modified chip that has been programmed to match. Otherwise, the car would reject the key and refuse to start.

Key for Wired

Saab cars typically come with two keys upon purchase. If you have only one, it is an ideal idea to purchase an extra key fob as quickly as you can since if you lose it, the car will require the replacement of a CIM unit, and the locking cylinders will need to be replaced. This can be costly especially if you're purchasing a used car.

The next step is connecting the wires of columns and row to your microcontroller. This is the most laborious part of the project and it will require a lot of soldering. There's no standard way to do this, but it is essential to determine the route you'll take and solder the columns and rows. There are 22 microcontroller pins and wires to connect to this keyboard. It has five rows and 17 columns.

After the rows and column are soldered together then it's time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from getting shorted. The diode allows current to only flow in one direction. It has a visual indicator of a black line that shows which way current will flow.

Sanabria says that some of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 can assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer data. The tools connect to the OBD port and guide the customer through the process, making it more simple than replacing the computer in the vehicle.

Jumpstarting the battery

The majority of people have a set in their trunk to jump-start a vehicle in an emergency, but it might not be the best idea for newer cars. These cars have a variety of digital and electronic devices that communicate with one another. A voltage spike when a battery is connected to another one could cause damage to the parts, rendering your car undriveable.

Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".)

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

Once the cables are connected, turn on the disabled vehicle and allow it to run for around five minutes before you disconnect the cables in reverse order. Be aware that the battery of your Saab 9-3 is recharged when you drive, and it can take a while for the battery to come back to normal. You should invest in another key fob when you can. The replacement of the one that works requires the installation and programming of a new computer chip.

Replacement Case

Many saab 900 key owners have only one key for their car and if they lose that the cost will be. It's costly to add an additional key and it requires replacing the CIM or TWICE in the case of older models.
