Five Tools Everybody Who Works In The Saab Ignition Key Replacement Industry Should Be Utilizing
Saab Key Programming

Saab cars built since 1994 use an immobilizer system based on keys that are coded. A new transponder is required in order to enable the addition of an extra key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

This can be expensive. You should always keep an extra set of keys on hand.

Transponder key

The transponder is a piece of key that is equipped with an electronic chip. This chip sends a signal when the key is placed into the ignition. The car will then check the signal to see whether it is identical to the one in the key. If the signals match then the car will be able to open and start. This is an excellent way to protect your car from theft.

Transponder keys can be a popular addition to automobiles, but they are not as secure as traditional metal keys. The metal portion of a traditional keys can be easily cut and copied, however the transponder is protected by an electronic chip that protects it. The chip is equipped with an individual code that is encoded into the car's system 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 so if the key fob has an unmodified chip that has been programmed to match the original. The car will not start in the event that the key has not been programmed to match.

It's crucial to ensure that you have an extra key for your Saab. This is particularly important if you live in a rural area where there are many car thieves. The good news is that it's possible to obtain a replacement key for your Saab without having to go to an auto dealer and pay the hefty prices they ask. You can have a replacement key created on the spot for less than half of what you would pay at dealerships.

Key for Wired

Saab cars are usually provided with two keys. If you own only one, you should purchase an additional key as quickly as you can. This is because if you lose it and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be expensive especially for used vehicles.

The next step is to connect the wires for the column and row to the microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. There isn't a standard way to accomplish this, but it is important to think about 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.

After the rows and column are soldered together then it's time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current and prevent them from getting shorted. The diode allows current to only flow in only one direction. It features a visual indicator that is black, that indicates which direction current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in certain instances replace keys in the program and restore lost immobilizer data Sanabria says. The tools plug into OBD ports and guide the user through each step making the process simpler than replacing the car's computer.

Jump starting the battery

Most people keep a set of jumper cables in their trunk for emergency situations, but jumping a battery in newer cars might not be the most efficient option. These cars have a variety of electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another battery could fry these components and render your car undriveable.

Connect the cables to the vehicle working. Let it run for two minutes. 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 an unpainted, clean metal surface underneath the disabled car's hood--the engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite the gasoline inside the engine compartment.

Once the cables are connected the disabled vehicle and let it run for about five minutes before you disconnect the cables in reverse order. Be aware that the battery in the Saab 9-3 will be charged while you drive, so it could take a while for the battery to come back to its original level. It is a good idea to purchase a spare fob as soon as you can, since 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 are not trying to steal the car.

Replacement case

Saab owners often only have one car key, and if it is lost, they'll be charged. saab 9-5 key replacement to buy a key and requires replacing the CIM or TWICE for older models. It is best to have a second key in the event of theft or other disaster, and the best way is to purchase a second key as quickly as you can. Even when the key is "new" it will not function.

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