Saab Key Programming

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

It can be costly. It is recommended to always have a spare set of keys available.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal back to the car when it is inserted into the ignition. The car then checks the signal to determine whether it is identical to that of the key. If the signals match, the car will unlock itself and begin. This is a great method to protect your vehicle from theft.

Transponder keys could be a popular addition to cars, but they're not as secure as traditional metal keys. While the metal part of a traditional key could be cut and copied but a transponder key is protected by an electronic chip. This chip has a unique code that is 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 it has a chip that is unmodified and has been programmed to match. The car will not start in the event that the key has not been programmed to match.

It's crucial to ensure that you have an extra key for your saab 93 replacement key. This is particularly true if you reside in a rural area with numerous car thieves. You can get a new key for your saab key replacement near me by going to the dealership without paying their pricey cost. You can get an original key made on the spot for less than half what you would pay at an auto dealer.

Key for Wired

Saab cars are usually delivered with two keys. If you have only one, it's a good idea to get an extra key fob as soon as possible as if you lose it, your car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This can be expensive especially for cars that are used.

The next step is to connect the row and columns wires to your microcontroller. This is the most tedious part of the project, and it will require lots of soldering. It's not a standard way to go about it, but you must determine how to route and connect 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 columns and rows are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. The diode allows current to only flow in only one direction. It features a visual indicator with a black band that shows which way current will flow.

Sanabria says that some of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 will assist customers shopping or DIY customers to program replacement key for saab 93 keys and restore immobilizer information. The tools connect to the OBD port and guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jump starting the battery

The majority of people have an assortment of tools in their trunk to jump-start their vehicle in an emergency, but it might not be a good idea for cars with more modern technology. These cars have a variety of electronic devices and computers that communicate with one another. A voltage spike when a battery is connected to another one could cause damage to the parts making your car unusable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block is an ideal choice. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, you can start the vehicle you are not using and let it run for approximately five minutes before disconnecting the cables in reverse order. The battery in your saab key battery replacement 9-3 will recharge as you drive. It will take a while for it to drop back down. It's a good idea to 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 a special program to convince the system that your lost keys aren't trying to steal the car.

replacement saab key case

Saab owners usually have only one car key, and if that is lost, they'll be charged. The reason for this is that it's costly to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is recommended to have a second key in the event of theft or other disaster, and the best way is to buy an extra key as soon as you are able to. But don't buy a used key even the case that it's "new." Keys that are claimed as new from a second-hand store will not work and are almost guaranteed to fail in the most critical moment.

The dealer will charge you the most expensive dollar for only one working key. We can, however, reset and reprogram the computer's EEPROM to accept the new key without having to replace the entire system. This can save you a significant amount of money. It's also much less expensive than waiting until you lose your one key.
