Saab Key Programming

Saab cars made since 1994 use an immobilizer system based on key codes. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The issue is that this can be extremely expensive. This is why it is important to always keep a spare key in your possession.

Transponder key

The transponder keys are keys with an electronic chip that sends a signal to the car when it is inserted into ignition. The car then checks the signal to see if it matches the one in the key. If the signals are in sync, the car will unlock and start. This is a great way to deter car theft and keep your car safe from thieves.

Transponder keys could be an increasingly popular feature for automobiles, but they are not as secure as traditional metal keys. While the metal parts of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip is a unique code that is programmed into a car's computers in order to identify it.

The car will recognize the saab fob key replacement keyfob and allow it to turn on. But, it's only able to do this if your key fob is equipped with a chip that is not modified that has been programmed to match. In the absence of that, the car will reject the key and not start.

It is vital to have an extra Saab key. This is particularly important if you reside in a rural area with numerous car thieves. The good news is that you can get a replacement key for your Saab Ignition Key Replacement without having to go to a dealership and pay the expensive prices that they ask. You can have a replacement key made on the spot for less than half what you would spend at dealerships.

Key for Wired

Saab cars are typically delivered with two keys. If you have only one, it's recommended to purchase an additional key fob as soon as is possible in case you lose it, your car will require the replacement of a CIM unit, and the locking cylinders will need to be replaced. This can be costly especially if you're purchasing a used vehicle.

The next step is to wire the wires of the column and row to the microcontroller. This is the most laborious component of the project and will require lots of soldering. There isn't a standard way to accomplish this, however it is important to think about the route you'll take and solder the rows and columns. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has five rows and 17 columns.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this, you need to place a diode over each pin on the key switch and then solder it. This will shield the pins of the key switch from current and keep them from being shorted. The diode will only allow the flow of current to be in one direction, and it also has a an indicator of black color that indicates which way the current will flow.

Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can aid shop customers or DIY customers in certain instances program replacement saab key keys and restore the lost immobilizer's data, Sanabria says. The tools connect to the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunk in case of emergency however, jumping a battery on modern vehicles may not be the most efficient option. These vehicles are equipped with many digital and computer systems that communicate with each other. A voltage spike when the battery is connected another can fry the components and render your vehicle unusable.

Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the non-working one. 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 underneath the vehicle's hood. An engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery because this could cause an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, begin the car and allow it to run for around five minutes. Then disconnect them in reverse. Remember that the battery on the Saab 9-3 will be charged during your drive, which means it could take a while to get the battery back down again. You should invest in an additional key fob when you can. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement Case

Saab owners often only have one car key, and if that is lost, they'll be charged. It's expensive to buy a key and requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other catastrophe it is recommended to have a spare key. Even it's "new" it won't work.

The dealer will charge you the highest dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM to get it ready to accept a replacement key without replacing the entire system. This can help you save money. It's also cheaper than waiting until you lose your one key.
