Saab Key Programming

saab replacement keys cars built since about 1994 have an immobilizer feature built on coded keys. A new transponder is required for addition of a second key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that this could be quite costly. It is recommended to always have a spare set of keys available.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal back to the car when it is put into the ignition. The car then examines the signal to determine if it matches the one in the key. If the signals are the same the car will then unlock itself and start. This is a great way to deter auto theft and keep your vehicle secure from thieves.

Transponder keys are an extremely popular accessory for cars, but they are not as secure as traditional metal keys. The metal component of a traditional key is easily cut and copied, however transponders are protected by an electronic chip that guards it. This chip contains a unique code that is programmed into the car's computers to identify it.

The car will recognize the saab Key programmer keyfob and allow it to turn on. The car will only recognize the key fob when it has an unmodified chip and has been programmed to match. The car will not start in the event that the key has not been programmed to match.

It is vital to have an extra Saab key. This is especially true if you reside in a rural location that has numerous car thieves. The good part is that you can find a replacement key to your Saab without needing to visit an auto dealer and pay the high prices that they charge. You can get the replacement key on the spot for less than half of the cost you would pay at the dealership.

Wired key

Saab cars typically come with two keys when they're new. If you only have one, it is a good idea to get an extra key fob as soon as possible, because if you lose it, your car will require a new CIM unit, and the locking cylinders will need to be replaced. This could be expensive, especially if you are buying a second-hand car.

The next step is to connect the wires of the column and row to the microcontroller. This is the most laborious part of the project and will require a lot of soldering. There's no standard way to do this, but it's important to plan out how you will route and solder the columns and rows. There are 22 microcontroller wires and pins to connect for this keyboard. It includes 5 rows and 17 columns.

Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, place a diode on each pin on the key switch and solder it. This will protect the pins of the key switch from current and keep them from being shorted. A diode lets current only flow in one direction. It has a visual indicator of a black line that indicates which direction current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 PRO and Saab Key Programmer IM508 -- could aid shop customers or DIY users in some cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools connect to OBD ports and help the customer through each step, making the process easier than replacing the vehicle's computer.

Jumpstarting the battery

Most people keep an item in their trunks to jump-start a car in case of emergency, but this might not be a good idea for cars with more modern technology. These vehicles are equipped with many electronic devices and computers that communicate with one another. A surge of voltage when batteries are connected to another can fry the components, rendering your car undriveable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface underneath the hood of the damaged vehicle. 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 result in a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, start the vehicle that is disabled and allow it to run for around five minutes before you disconnect the cables in reverse order. Be aware that the battery in your Saab 9-3 is charged while you drive, so it can take a while for the battery to go back down again. It's a good idea to buy a spare key fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and special programming to convince it that the lost keys aren't trying to steal the car.

Replacement Case

Saab owners usually only have one car key, and if that is lost, they'll be charged. The reason is that it's not inexpensive to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is best to have a second key in case of theft or other disaster the best solution is to purchase an extra key as early as you can. Don't buy a secondhand key, even the case that it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't perform and are almost certain to fail at the crucial moment.

Most locksmiths cannot help you when you only have one working key and the dealer will charge high prices to replace the computer in your vehicle to make a new replacement. However, we can reset and re-program your computer's EEPROM to accept the new key, without replacing the entire system. This could save you a lot of money. It's less expensive instead of waiting until you lose the only key.
