Saab Key Programming

Saab cars built since 1994 use an immobilizer system that relies on keys that are coded. In order to add a second key, it requires an entirely new transponder and programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The issue is that it can be very costly. It is recommended to always have an extra set of keys at hand.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal to car when it is placed in the ignition. The car will check to see if the signal matches the one on the key. If the signals match, the car will unlock and start. This is a great way to prevent auto theft and keep your car safe from thieves.

Transponder keys may be an increasingly popular feature for cars, but they are not as secure as traditional metal keys. While the metal part of a conventional key can be cut and saab 900 Key copied but a transponder key is protected by an electronic chip. The chip has a unique code embedded into the car's computer to identify it.

The car will recognize the Saab keyfob and allow it to be turned on. The car can only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. In the absence of that, the car will reject the key and refuse to start.

It is essential to have a spare saab spare key key. This is especially true especially if you live in a rural area that is home to numerous car thieves. You can purchase a new key for «link» your Saab by going to the dealership without paying pricey cost. You can have the replacement key on the spot for less than half the price you'd spend at the dealership.

Wired key

Saab cars are usually 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, because if you lose it, your car will require the replacement of a CIM unit, and the locking cylinders will have to be replaced. This can be expensive especially for cars that are used.

The next step is to connect the wires for the column and row to the microcontroller. This is the most tedious component of the project and will require lots of soldering. It's not a standard way to go about it, but you need to consider how you will route and solder each column and row. For this keyboard, there are five rows and 17 columns, which means 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. Solder a diode on each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. A diode lets current only flow in only one direction. It comes with a visual indicator of a black line that shows which way current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY customers in certain cases program replacement keys and restore lost immobilizer information, Sanabria says. The tools connect to OBD ports and guide the user through each step which makes the process much easier than replacing the vehicle's computer.

Jump-starting the battery

A lot of people keep an item in their trunks to jump-start a vehicle in an emergency, but this might not be a good idea for vehicles that are newer. These vehicles are equipped with many electronic devices and computers that communicate with each other. A surge in voltage when a battery is connected to another can fry the components making your car inoperable.

Start the vehicle you are using and let it run for about two minutes before connecting the cables to the non-working one. 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 under the hood of the affected car. The engine block is an excellent choice. Do not connect the black cable to the negative terminal on the dead battery as this could trigger an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle and let it run for approximately five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will recharge as you drive. It will take a while for it to return to its original state. You should invest in an additional key fob as soon as possible. Replacing the one that works requires the installation and programming of a brand new computer chip.

Replacement case

Many Saab owners only have one key for their vehicle and if they lose it, it's going to cost them. The reason is that it's not inexpensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or any other catastrophe, it is best to have an extra key. Don't buy a secondhand key even when it's "new." Keys that are claimed to be new from a second-hand store will not work and are almost guaranteed to fail in the most critical moment.

Most locksmiths aren't able to help in the event that you only have one working key, and the dealer will charge you high fees to replace the computer in your vehicle for a replacement. We can reset and reprogram the computer's EEEPROM to get it ready to accept a replacement key without replacing the entire system. This could save you a significant amount of money. It's cheaper to do this than waiting until you lose your only key.
