saab 93 key fob Key Programming

saab keys cars built since about 1994 come with an immobilizer system that is based on codes for keys. To add an additional key, you need a new transponder, as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

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

Transponder key

The transponder keys are keys with an electronic chip that sends a signal back to the car when it is put into the ignition. The car will check to see whether the signal matches with the one on the key. If the signals match it will open and start. This is a great way to protect your car from theft.

Transponder keys are an increasingly popular feature for automobiles, but they are not as secure as traditional metal keys. The metal part of the traditional keys can be easily copied and cut, but transponders have an electronic chip that guards it. The chip has a unique code that is inserted into a car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it can only do so if the key fob is equipped with a chip that is not modified that has been programmed to match. The car will not start when the key isn't programmed to match.

It is vital to have a spare saab car key key. This is particularly important when you live in a rural location that has numerous car thieves. The good news is that it's possible to find a replacement key to your Saab without having to go to an auto dealership and pay the hefty prices that they demand.

Key for Wired

saab key battery replacement cars are usually delivered with two keys. If you only have one, it is an ideal idea to purchase an extra key fob as soon as possible as if you lose it, your car will require a new CIM unit and the locking cylinders will need to be replaced. This can be costly especially if purchasing a used vehicle.

The next step is to wire the wires of the column and row to the microcontroller. This is the most difficult part of the project and will require a large deal of soldering. There's no standard way to do it, but you should plan how to open a saab 93 without a key to route and solder each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the rows and column are soldered together, it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins of the key switch from current and stop them from being shorted. The diode will only allow current to flow in one direction, and it also has a an indicator in black that indicates which way the current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY users in some cases replace keys in the program and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer inside the vehicle.

Jump starting the battery

The majority of people have a set of jumper cables in their trunks to use in an emergency however, jumping a battery for newer automobiles might not be the best choice. These vehicles have many electronic devices and computers that communicate with one another. A voltage spike when the battery is connected another battery could damage the components making your car unusable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the car's hood. The engine block would be a good option. Do not connect the black cable to the negative terminal of the dead battery, as this could cause a spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the disabled vehicle and let it run for approximately five minutes before disconnecting them in reverse order. Be aware that the battery in your Saab 9-3 is charged when you drive, and it can take a while for the battery to go down. It's a good idea invest in a spare key fob as soon as you can, because replacing the sole working one requires the installation of a brand new computer module and special programming to convince the system that your lost keys aren't attempting to steal the car.

Replacement Case

Saab owners usually have only one car key, and if that is lost saab key (Suggested Web page), they'll be charged. The reason for this is that it's expensive to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other calamity it is advisable to have a spare key. But don't buy a used key, even it's "new." Claimed-new keys from aftermarket sellers will not be effective and are almost guaranteed to fail at the crucial moment.

The dealer will charge the highest dollar for only one working key. We can reset and reprogram the EEEPROM of your computer to be able to accept a new key without replacing the entire system. That can save you a lot of money. It's also much less expensive than waiting until you lose your only key.
