Saab cars made from 1994 have an immobilizer system that is based on a set of keys. In order to add a second key, it requires an entirely new transponder and programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

The issue is that this can be extremely expensive. It is recommended to always have a spare set of keys at hand.

Transponder key

The transponder keys are keys equipped with an electronic chip. It transmits a signal to the car when it is inserted into the ignition. The car then checks the signal to determine whether it is the same as the one on the key. If the signals are identical, the car will unlock itself and begin. This is a fantastic way to protect your vehicle from theft.

Transponder keys are an extremely popular accessory for cars, but they are not as secure as traditional keys made of metal. While the metal part of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. This chip contains a unique code that is programmed into the car's computers to identify it.

The car will recognize the saab ignition key Replacement keyfob and permit it to be turned on. The car can only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. Otherwise, the car will reject the key and won't start.

This can be costly particularly if you are buying a second-hand car.

The next step is to wire the wires of the column and row to the microcontroller. This is the most tedious component of the project and it will require a lot of soldering. There is no standard method to accomplish this, but it is essential to determine the route you'll take and solder the rows and columns. 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 the key switches. To do this, you need to place a diode over each pin on the key switch and solder it. This will shield the pins that are used for key switches from current and keep them from being shorted. The diode allows current to only flow in one direction. It has a visual indicator that is black, that indicates which direction current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can help customers in the shop, or even DIY customers in some cases programme replacement keys and recover the lost saab keys immobilizer's data, Sanabria says. The tools plug into OBD ports and guide the user through each step making the process simpler than replacing the vehicle's computer.

Jump-starting the battery

Most people keep an assortment of tools in their trunks to jump-start their vehicle in the event of an emergency, but it may not be a good idea for vehicles that are newer. These vehicles have many digital and computer systems that communicate with each other. A voltage surge while the battery is connected to another can fry these components, rendering your vehicle unable to drive.

Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the disabled car's hood--the engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline that is in the engine compartment.

After the cables have been connected, begin the car and let it run about five minutes. Then, disconnect the cables in reverse. Be aware that the battery in your Saab 9-3 is charged while you drive, so it may take some time to get the battery back down again. It's a good idea to purchase a spare fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and a special program to convince it that the lost keys aren't attempting to steal the car.

Replacement Case

Many Saab owners have only one key for their car and if they lose that key, it will cost them. It's costly to add the key and also requires replacing the CIM or TWICE for older models. It's best to have a second key in the event of theft or other disaster and the best option is to buy an extra key as soon as you can. Even it's "new", it won't work.

The dealer will charge you the most expensive dollars if you only have one working key. However, we can reset and reprogram the computer's EEPROM in order to prepare it to accept the new key, without replacing the whole system. This can save you a significant amount of money. It's also much less expensive than waiting until you lose your only key.
