10 Misconceptions That Your Boss May Have Concerning Saab Ignition Key Replacement

saab ignition key Key Programming

saab 9-3 key fob programming cars produced since 1994 use an immobilizer system that relies on keys that are coded. To add an additional key, you need a new transponder, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

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

Transponder key

The transponder can be described as a key that is equipped with an electronic chip. The chip transmits a signal when the key is put in the ignition. The car then examines the signal to determine if it matches the one on the key. If the signals are identical the car will then unlock itself and begin. This is a great way to avoid auto theft and keep your vehicle secure from thieves.

Transponder keys are a popular feature in automobiles, however you must be aware that they aren't as secure as traditional keys made of metal. The metal part of the traditional key can easily be cut and copied, however transponders are protected by an electronic chip that guards it. The chip is equipped with a unique code that is programmed into the car's computer to identify it.

When a saab key fob, read this article, is used, the car recognizes it and allows it to turn on. However, it is only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. If not, the car will reject the key and refuse to start.

Wired key

saab key programming cars are usually supplied with two keys. If you own only one, you need to 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 costly especially if purchasing a used vehicle.

The next step is to wire the wires of the column and row to the microcontroller. This is the most difficult aspect of the project and it will require lots of soldering. There is no standard method to do this, but it's important to plan out the routes you'll use to solder the rows and columns. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 column.

After the columns and rows are soldered together It is now time to connect the key switches. Solder a diode to each key switch pin. This will shield the key switch pins from current and keep them from being shorted. The diode will only allow the current to flow in a single direction, and has a an indicator in black that indicates which way the current will flow.

Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and automatically guide the customer through the process, making it easier than replacing the computer inside the vehicle.

Jump starting the battery

Most people keep a set in their trunks to jump-start their vehicle in the event of an emergency, but this might not be the best idea for cars with more modern technology. These vehicles are equipped with numerous digital and computers that communicate with one another. A surge in voltage when batteries are connected to another one could cause damage to the parts and render your vehicle unusable.

Start the working vehicle and let it run for about two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface under the hood of the affected vehicle. The engine block is a good alternative. Don't connect the black cable to the negative terminal of the dead battery, since it could spark a spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle that is disabled and let it run for about five minutes before disconnecting the cables in reverse order. The battery in your saab key fob repair 9-3 will be recharged as you drive. It takes a while for it to recharge again. It's a good idea invest in a spare key fob as soon as you can, since replacing the sole working one requires the installation of a new computer module and special programming to convince the system that your lost keys aren't attempting to steal the car.

Replacement Case

Many Saab owners only have one key for their car and if they lose it, they'll be charged. The reason for this is that it's not cheap to replace a key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's best to have a second key in case of theft or any other catastrophe and the best option is to purchase an additional key as early as you can. Even if the key is "new" it won't work.

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