Are You Responsible For A Saab Ignition Key Replacement Budget? 12 Top Notch Ways To Spend Your Money
Saab Key Programming

Saab cars that were built prior to 1994 have an immobilizer system made up of coded keys. A new transponder is required to allow the addition of an additional key, and special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

The issue is that it can be very costly. It is always advisable to keep a spare set of keys at hand.

Transponder key

The transponder key is a key with an electronic chip that transmits a signal to the car when it is put into the ignition. The car checks to see if the signal matches the one on the key. If the signals are identical the car will be able to unlock itself and start. This is a great way to deter car theft and keep your vehicle secure from thieves.

Transponder keys are a popular feature in automobiles, however you must be aware that they're not as secure as traditional metal keys. The metal part of the traditional key is easily cut and copied, whereas transponders are protected by an electronic chip which protects it. This chip has a unique code that is programmed into the car's computers to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. However, it is only able to do this if the fob has a non-modified chip that has been programmed to match. In the absence of that, the car will refuse to accept the key and will not start.

It's essential to ensure that you have a spare key for your Saab. This is especially important when you live in a rural area, where there are numerous car thieves. You can get a brand new key for your Saab by going to the dealership without paying high prices. You can get the replacement key on the spot for less than half what you would pay at an auto dealer.

Key for Wired

Saab cars usually come with two keys when new. If new saab key have only one, it is best to acquire an extra key fob as soon as you can in case you lose it, your car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This can be costly especially for used vehicles.

The next step is to wire the row and column wires to the microcontroller. This is the most challenging part of the project and will require a large deal of soldering. It's not a standard way to do it, but you need to determine how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins 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 on the key switch from current and stop them from being shorted. A diode can only allow the flow of current to be in one direction, and it has the black band as a visual indicator that indicates the direction in which current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or DIY customers in some cases replace keys in the program and restore lost immobilizer data Sanabria says. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the vehicle's computer.

Jump starting the battery

A lot of people keep the set in their trunks to start a car in an emergency, but it might not be a good idea for vehicles that are newer. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A surge in voltage while the battery is connected to another could cause damage to these components and render your vehicle undriveable.

Connect the cables to the vehicle working. 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 to a clean unpainted metal surface underneath the hood of your disabled vehicle. The engine block is a great choice. Don't connect the black cable to the negative terminal on the dead battery, since this could cause a spark that ignites the gasoline in the engine bay.

Once the cables are connected the vehicle that is disabled and let it run for about five minutes before you disconnect them in reverse order. The battery in the Saab 9-3 will charge as you drive. It will take some time for it to recharge again. You should invest in an additional key fob as soon as possible. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Saab owners usually only have one car key, and if it is lost, they'll be charged. It's expensive to purchase keys and will require replacing the CIM or TWICE in the case of older models. It's best to have a second key in case of theft or other disaster and the best option is to purchase an additional key as soon as you can. However, don't purchase a secondhand key even if it's "new." Claimed-new keys from sellers selling aftermarket keys won't work and are likely to fail in the crucial moment.


The dealer will charge the highest dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer to be able to accept a replacement key without the need to replace the entire system. That can save you a significant amount of money. It's also less expensive than waiting until you lose your only key.
