A Comprehensive Guide To Saab Ignition Key Replacement. Ultimate Guide To Saab Ignition Key Replacement
Saab Key Programming

Saab cars made since 1994 utilize an immobilizer system that is based on a set of keys. A new transponder is required for the inclusion of an additional key, as well as special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

The problem is that it can be quite costly. It is always advisable to keep a spare set of keys in your possession.

Transponder key

The transponder is a key that is equipped with an electronic chip. The chip transmits a signal when the key is placed in the ignition. The car checks to see if the signal matches the one on the key. If the signals are identical, the car will unlock itself and start. This is an excellent way to guard your car against theft.

Transponder keys are a popular feature in automobiles, but you must be aware that they're not as secure as traditional metal keys. The metal component of the traditional key can easily be cut or copied, while the transponder is protected by an electronic chip which protects it. This chip contains an unique code that is 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. However, it can only do this if the fob is unmodified and has a chip that has been programmed to match. The car won't start in the event that the key is not programmed to match.

It's essential to ensure that you have an extra key for your Saab. This is particularly important especially if you reside in a rural area, where there are a lot of car burglars. You can purchase a new key for your Saab by visiting the dealership without paying expensive costs. In the majority of cases, you can have a new key created on-the-spot for less than half the cost you'd pay at an auto dealer.

Key for Wired

Saab cars typically come with two keys when they are new. If you only have one, it is recommended 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 have to be replaced. This can be costly particularly if you are buying a used car.

The next step is connecting the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There isn't a standard method to go about it, however, you should think about how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins from current, preventing them from being shorted. The diode allows current to only flow in only one direction. It comes with a visual indicator of a black line that shows which way current will flow.


A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may help shop customers or even DIY customers in certain cases programme replacement keys and recover lost immobilizer data Sanabria says. The tools connect to the OBD port and guide the customer through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump starting the battery

Most people keep a few sets of jumper cables in their trunk in case of emergency however, jumping a battery for newer automobiles might not be the best choice. These vehicles are equipped with many digital and computer systems that communicate with one another. A voltage surge while a battery is hooked up to another could cause damage to the components and render your vehicle unable to drive.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface underneath the hood of your disabled vehicle. The engine block is a good option. saab 9-3 key fob programming The Keylab connect the black cable to the negative terminal of the dead battery, as it could spark a spark that ignites the gasoline in the engine bay.

After the cables have been connected, start the vehicle and let it run for approximately five minutes. Then, disconnect the cables in reverse. Keep in mind that the battery on the Saab 9-3 gets recharged during your drive, which means it could take a while for the battery to come down. You should invest in a second key fob, when you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement Case

Saab owners usually have only one car key, and if it is lost, they'll be charged. It's expensive to buy the key and also requires replacing the CIM or TWICE for older models. It is best to have a backup key in the event of theft or any other catastrophe and the best option is to purchase an additional key as soon as you are able to. Don't purchase a used key, even it's "new." Keys that are claimed-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 highest dollar if you have only one working key. We can reset and reprogram the EEEPROM of your computer to make it ready to accept a replacement key without having to replace the entire system. This can save you a lot of money. It's less expensive than waiting until you lose your only key.
