Saab Key Programming

Saab cars built from 1994 have an immobilizer system that relies on keys that are coded. A new transponder is required for the addition of an extra key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

It can be costly. You should always keep an extra set of keys on hand.

Transponder key

The transponder is a type of key equipped with an electronic chip. The chip sends a signal when the key is inserted into the ignition. The car will then check the signal to see whether it is the same as the one that is in the key. If the signals are in sync it will unlock and begin. This is a great way to safeguard your car from theft.

Transponder keys could be an extremely popular accessory for cars, but they are not as safe as traditional keys made of metal. The metal component of a traditional key can easily be cut and copied, however transponders are protected by an electronic chip which protects it. The chip is a unique code that's programmed into a car's computers in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car will only recognize the key fob if it is equipped with an unmodified chip and programmed to match. If not, the car will reject the key and not start.

It's essential to ensure that you have a spare key for your Saab. This is especially true for those who live in a rural location where there are a lot of car thieves. The good part is that you can get a replacement key for your Saab without needing to visit a dealer and pay the high prices they ask. In most instances, you can get an original key made on the spot at a fraction of the cost of what you would pay at dealerships.

Wired key

saab keys replacement cars typically come with two keys when they are new. If you only own one, you should purchase an extra key as soon as you can. This is because if you lose it and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly particularly for used cars.

The next step is to wire the wires for the column and row to the microcontroller. This is the toughest aspect of the project and will require lots of soldering. There is no standard method to accomplish this, however it is crucial to plan the way you'll route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered together, it is time to connect the key switches. To do this you must place a diode on each pin on the key switch and solder it. This will shield the pins from current, and prevent them from getting shorted. A diode lets current only flow in one direction. It has a visual indicator, a black band, that shows the direction in which the 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 programme replacement keys and recover the lost immobilizer's data, Sanabria says. The tools connect to the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep a set of jumper cables in their trunks for emergency situations however, jumping a battery on modern vehicles may not be the best choice. They have numerous digital and electronic devices that communicate with each other. A surge in voltage when batteries are connected to another battery could damage the components and render your vehicle unusable.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip How To Program Saab 9-3 Key Fob the positive terminal of the battery that is good. (It will read "POS" or "+".) 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. Don't connect the black cable to the negative terminal of the dead battery because this could cause an ignition that ignites the gasoline in the engine bay.

Once the cables are connected the disabled vehicle and allow it to run for around five minutes before disconnecting the cables in reverse order. Keep in mind that the battery on the Saab 9-3 will be charged when you drive, and it could take a while for the battery to come back to its original level. It is recommended to purchase another key fob when you can. 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 that key, it will cost them. The reason for this is that it's not inexpensive to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's best to have a backup key in case of theft or any other catastrophe the best solution is to purchase a second key as soon as you are able to. Don't buy a secondhand key even when it's "new." Claimed-new keys purchased from third-party sellers won't work and are likely to fail at the critical moment.

The majority of locksmiths won't be able to help with a single working key, and the dealer will charge you for the cost of replacing the computer in your car to make a replacement. We can reset and reprogram the computer's EEEPROM to get it ready to accept a replacement key without having to replace the entire system. This can save you a lot of money. It's also less expensive than waiting until you lose your only key.
